 ## Workspace Restriction
 
-Filesystem tools (`read_file`, `write_file`, `edit_file`, `list_dir`, `apply_patch`) resolve paths through the workspace path resolver (`agent/tools/filesystem.py` / `agent/tools/path_utils.py`), which enforces that the resolved path must lie under the active workspace when workspace restriction is enabled. The media upload directory is always an internal extra read root while restricted.
+Filesystem tools (`read_file`, `write_file`, `edit_file`, `list_dir`) resolve paths through `_resolve_path` (`agent/tools/filesystem.py`), which enforces that the resolved path must lie under `allowed_dir` (typically the configured workspace), plus the media upload directory (`get_media_dir()`) and any `extra_allowed_dirs`.
 
-Additional filesystem roots must be capability-specific. `extra_allowed_dirs` is a legacy read-only alias. Use `extra_read_allowed_dirs` for read-only roots, `extra_write_allowed_dirs` only when a write-capable tool is intentionally allowed to modify an extra directory, and exact file allowlists when a tool may modify only specific files.
+Shell execution (`ExecTool`, `agent/tools/shell.py`) also respects `restrict_to_workspace`: if enabled and `working_dir` is outside the workspace, the command is rejected before execution.
 
-Shell execution (`ExecTool`, `agent/tools/shell.py`) also respects `restrict_to_workspace` as an application-level guard: if enabled and `working_dir` is outside the workspace, the command is rejected before execution, and command text is checked for obvious workspace escapes. This is not process-level isolation; use an exec sandbox backend for that.
+**Rule**: Any new path-handling logic must go through `_resolve_path` or perform an equivalent `allowed_dir` check.

-**Rule**: Any new path-handling logic must go through the workspace path resolver or perform an equivalent containment check with explicit read/write capability semantics.
 
 ## SSRF Protection
 
-All outbound HTTP requests from agent tools must pass through `validate_url_target` (`security/network.py`). By default it blocks loopback, RFC1918 private addresses, CGNAT ranges, link-local ranges, and cloud metadata endpoints (including `169.254.169.254`).

 The only escape hatch is `configure_ssrf_whitelist(cidrs)`, which reads from `config.tools.ssrf_whitelist` at load time.
 
-HTTP/SSE MCP transports are part of this boundary: validate configured MCP URLs before probing or constructing clients, and validate each outgoing HTTP request before redirects are followed. Local/private HTTP MCP endpoints are allowed only through the explicit SSRF whitelist. Stdio MCP servers are not part of the HTTP SSRF path.
-
 **Rule**: Do not add direct `httpx.get` / `requests.get` calls in tools. Route through the existing web fetch utilities or replicate the `validate_url_target` check.
 
 ## Shell Sandbox
 
-`tools/sandbox.py` provides optional command wrapping. The only backend currently shipped is `bwrap` (bubblewrap), intended for containerized deployments. On Windows and bare-metal Linux without `bwrap`, commands run in the native shell with workspace restriction as an application-level guard only.

+**Install from PyPI**
 
 ```bash
-python -m pip install nanobot-ai
+pip install nanobot-ai

-
-If pip reports `externally-managed-environment` on macOS or Linux, use the one-command installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or install inside a virtual environment.
-
-**Install from source**
-
-```bash
-git clone https://github.com/HKUDS/nanobot.git
-cd nanobot
-python -m pip install -e .
-```
-
-Verify the install:
-
-```bash
-nanobot --version
 ```
 
 ## 🚀 Quick Start
 
 **1. Initialize**
 
-Skip this step if the one-command setup already started the wizard and Quick Start finished there.
-
 ```bash
 nanobot onboard
 ```
 
-Use `nanobot onboard --wizard` if you prefer an interactive setup.
-
 **2. Configure** (`~/.nanobot/config.json`)
 
-Skip this step if you already configured provider and model settings in the wizard.
+Configure these **two parts** in your config (other options have defaults). Add or merge the following blocks into your existing config instead of replacing the whole file.
 
-`nanobot onboard` creates `~/.nanobot/config.json` and `~/.nanobot/workspace/`. Configure these **two parts** in the config file. Add or merge the following blocks into the existing file instead of replacing the whole file.
+*Set your API key* (e.g. [OpenRouter](https://openrouter.ai/keys), recommended for global users):
-
-The example below uses a generic OpenAI-compatible `custom` provider so the compact path does not recommend one hosted service. Provider examples are recipes, not rankings or endorsements. For copyable provider-specific setup, see [Provider Cookbook](./docs/provider-cookbook.md).
-
-*Set your API key*:
 
 ```json
 {
   "providers": {
-    "custom": {
+    "openrouter": {
-      "apiKey": "your-api-key",
+      "apiKey": "sk-or-v1-xxx"
-      "apiBase": "https://api.example.com/v1"
     }
   }
 }
 ```
 
-*Set a model preset and make it active*:
+*Set your model* (optionally pin a provider — defaults to auto-detection):
 
 ```json
 {
-  "modelPresets": {
-    "primary": {
-      "label": "Primary",
-      "provider": "custom",
-      "model": "model-id-from-your-provider",
-      "maxTokens": 8192,
-      "contextWindowTokens": 200000,
-      "temperature": 0.1
-    }
-  },
   "agents": {
     "defaults": {
-      "modelPreset": "primary"
+      "provider": "openrouter",
+      "model": "anthropic/claude-opus-4-6"
     }
   }
 }
 ```
 
-Direct `agents.defaults.provider` and `agents.defaults.model` still work for existing configs, but named presets are the recommended path because they also power `/model` switching and `fallbackModels`.
+**3. Chat**
-
-For another provider, the same config shape still applies:
-
-| Replace | Where |
-|---|---|
-| Provider config key | `providers.<provider>` |
-| API key | `providers.<provider>.apiKey` |
-| Preset provider name | `modelPresets.primary.provider` |
-| Model ID | `modelPresets.primary.model` |
-| Endpoint URL, only when needed | `providers.<provider>.apiBase` |
-
-**3. Open the WebUI**
-
-If Quick Start enabled the WebSocket channel, start the gateway:
-
-```bash
-nanobot gateway
-```
-
-Leave that terminal open, then open `http://127.0.0.1:8765` in your browser. Enter the WebUI password you set in the wizard, then send your first message there.
-Prefer not to keep a terminal open? Use `nanobot gateway --background`, then manage it with `nanobot gateway status`, `logs`, `restart`, and `stop`.
-
-For manual or terminal-only setup, test one CLI message:
-
-```bash
-nanobot status
-nanobot agent -m "Hello!"
-```
-
-In `nanobot status`, it is normal for most providers to say `not set`. The active preset's provider should be configured, and `Config` plus `Workspace` should show check marks.
-
-If that works, start an interactive chat:
 
 ```bash
 nanobot agent
 ```

-## After the First Reply Works
-
-Do not configure everything at once. Pick one next surface:
-
-If a local `nanobot agent` session can already answer normally, you can also ask nanobot to help configure itself: have it read the relevant docs, inspect your current config, make one specific next change, and tell you when to run `/restart`.

-## Reading Strategy
-
-Use the docs in this order when you are unsure where to go:
-
-1. If terminal commands or config files are new to you, [`start-without-technical-background.md`](./start-without-technical-background.md) explains the setup words and uses one concrete provider example so there is only one decision at a time.
-2. [`quick-start.md`](./quick-start.md) proves installation, config loading, and provider access.
-3. [`concepts.md`](./concepts.md) explains the runtime model so later pages are easier to scan.
-4. [`provider-cookbook.md`](./provider-cookbook.md) gives pasteable provider, fallback, local model, and Langfuse recipes.
-5. A task guide, such as [`chat-apps.md`](./chat-apps.md), [`image-generation.md`](./image-generation.md), or [`deployment.md`](./deployment.md), gets one workflow working.
-6. [`configuration.md`](./configuration.md) is the source of truth when you need a specific field, default value, or advanced option.
-7. [`troubleshooting.md`](./troubleshooting.md) helps isolate whether a failure is install, config, provider, gateway, channel, or tool related.

-Main files:
-
-| Area | Files |
-|---|---|
-| Message events and queue | `nanobot/bus/events.py`, `nanobot/bus/queue.py` |
-| Turn orchestration | `nanobot/agent/loop.py` |
-| Provider/tool conversation loop | `nanobot/agent/runner.py` |
-| Context construction | `nanobot/agent/context.py` |
-| Session storage and compaction | `nanobot/session/manager.py` |
-| Long-term memory and Dream | `nanobot/agent/memory.py` |
-
-## Agent Loop vs Agent Runner
-
-`AgentLoop` owns the channel-facing turn:
-
-- receives inbound messages;
-- determines the effective session and workspace scope;
-- builds context;
-- wires hooks, progress, and channel metadata;
-- publishes outbound messages.
-
-`AgentRunner` owns the model-facing loop:
-
-- sends messages to the selected provider;
-- handles streaming deltas and reasoning blocks;
-- executes tool calls;
-- feeds tool results back into the model;
-- stops when a final answer is produced or runtime limits are hit.
-
-Keep this split in mind when debugging. If a problem is about channel routing, session keys, workspace selection, or outbound delivery, start in `agent/loop.py`. If it is about provider calls, tool calls, streaming, or iteration limits, start in `agent/runner.py`.
-
-## Providers
-
-Provider metadata is centralized in `nanobot/providers/registry.py`. Configuration fields live in `nanobot/config/schema.py`.
-
-Provider selection uses:
-
-- explicit `agents.defaults.provider` or preset provider;
-- provider registry keywords;
-- API key prefixes and API base URL hints;
-- local provider fallback when `apiBase` is configured;
-- gateway fallback for providers that can route many model families.
-
-Provider implementations live in `nanobot/providers/`. Most hosted providers use the OpenAI-compatible implementation, while Anthropic, Azure OpenAI, AWS Bedrock, OpenAI Codex, and GitHub Copilot have specialized paths.
-
-Useful docs:
-
-- [`providers.md`](./providers.md) for practical setup;
-- [`configuration.md#providers`](./configuration.md#providers) for exact provider reference.
-
-## Channels
-
-Channels translate external platforms into `InboundMessage` events and send `OutboundMessage` events back to the platform.
-
-Main files:
-
-| Area | Files |
-|---|---|
-| Base channel contract | `nanobot/channels/base.py` |
-| Built-in channels | `nanobot/channels/*.py` |
-| Discovery and lifecycle | `nanobot/channels/manager.py` |
-| WebSocket/WebUI channel | `nanobot/channels/websocket.py` |
-
-Channels are discovered through built-in module scanning and plugin entry points. A custom channel should follow [`channel-plugin-guide.md`](./channel-plugin-guide.md).
-
-## WebUI and Gateway
-
-`nanobot gateway` starts:
-
-- enabled chat channels;
-- the WebSocket channel when configured;
-- workspace-scoped cron service;
-- system jobs such as Dream and heartbeat;
-- the health endpoint on `gateway.port`.
-
-The packaged WebUI is served by the WebSocket channel, not the health endpoint:
-
-| Surface | Default |
-|---|---|
-| Health endpoint | `http://127.0.0.1:18790/health` |
-| WebUI/WebSocket | `http://127.0.0.1:8765` |
-
-WebUI source lives in `webui/`. The production build is written to `nanobot/web/dist/` and bundled into the wheel.
-
-Useful docs:
-
-- [`webui.md`](./webui.md) for the WebUI user guide;
-- [`../webui/README.md`](../webui/README.md) for frontend source development;
-- [`websocket.md`](./websocket.md) for protocol details.
-
-## Tools
-
-Tools are discovered from `nanobot/agent/tools/` and plugin entry points.
-
-Important files:
-
-| Tool area | Files |
-|---|---|
-| Tool base and schema | `nanobot/agent/tools/base.py`, `nanobot/agent/tools/schema.py` |
-| Discovery | `nanobot/agent/tools/registry.py` |
-| Shell execution | `nanobot/agent/tools/shell.py` |
-| Filesystem tools | `nanobot/agent/tools/filesystem.py` |
-| Web search/fetch | `nanobot/agent/tools/web.py` |
-| MCP tools | `nanobot/agent/tools/mcp.py` |
-| Cron | `nanobot/agent/tools/cron.py`, `nanobot/cron/` |
-| Image generation | `nanobot/agent/tools/image_generation.py` |
-| Runtime self-inspection | `nanobot/agent/tools/self.py` |
-
-Tool behavior is part of the model contract. Keep user-visible tool names, schemas, and error messages stable unless a change is intentional.
-
-## Config and Paths
-
-The config schema lives in `nanobot/config/schema.py`. Loading and saving live in `nanobot/config/loader.py`. Runtime path helpers live in `nanobot/config/paths.py`.
-
-Defaults:
-
-| Path | Default |
-|---|---|
-| Config | `~/.nanobot/config.json` |
-| Workspace | `~/.nanobot/workspace/` |
-| Sessions | `<workspace>/sessions/*.jsonl` |
-| Memory | `<workspace>/memory/` |
-| Cron store | `<workspace>/cron/jobs.json` |
-| WebUI/media/log runtime data | config directory subdirectories such as `webui/`, `media/`, and `logs/` |
-
-The schema accepts both camelCase and snake_case keys, but saves config with camelCase aliases.
-
-## Memory and Sessions
-
-Session history is the near-term conversation replay. Memory is the longer-term workspace state.
-
-| Store | File area |
-|---|---|
-| Session JSONL files | `<workspace>/sessions/` |
-| Long-term memory | `<workspace>/memory/MEMORY.md` |
-| Consolidation source history | `<workspace>/memory/history.jsonl` |
-| Bootstrap identity files | `<workspace>/SOUL.md`, `<workspace>/USER.md`, templates under `nanobot/templates/` |
-
-Dream is implemented in `nanobot/agent/memory.py` and scheduled by the runtime when enabled.
-
-## Security Boundaries
-
-Security-sensitive code paths include:
-
-| Boundary | Files |
-|---|---|
-| Workspace scope | `nanobot/security/workspace_access.py`, `nanobot/security/workspace_policy.py` |
-| Shell sandboxing | `nanobot/agent/tools/shell.py` |
-| SSRF/network checks | `nanobot/security/network.py`, `nanobot/agent/tools/web.py` |
-| PTH guard and CLI startup security | `nanobot/security/` and CLI entrypoints |
-| Channel access control | channel config in `nanobot/channels/*.py` |
-
-When changing tools, channels, file access, WebUI workspace behavior, or network fetching, treat security as part of the functional behavior and update docs if the user-facing boundary changes.
-
-## Extension Points
-
-| Extension | How |
-|---|---|
-| Provider | Add `ProviderSpec` in `providers/registry.py`, add schema field in `config/schema.py`, implement provider only if the generic backend is not enough |
-| Channel | Implement `BaseChannel`, expose an entry point, follow [`channel-plugin-guide.md`](./channel-plugin-guide.md) |
-| Tool | Implement a tool under `agent/tools/` or expose a plugin entry point |
-| MCP | Add `tools.mcpServers` config |
-| Skill | Add workspace skill files under `<workspace>/skills/` or built-in skills under `nanobot/skills/` |
-
-Prefer existing registry/discovery patterns over ad hoc wiring.
-
-## Testing and Verification
-
-Common checks:
-
-```bash
-pytest tests/test_openai_api.py::test_function -v
-ruff check nanobot/
-cd webui && bun run test
-cd webui && bun run build
-```
-
-Choose tests based on the changed surface:
-
-| Change | Minimum useful verification |
-|---|---|
-| Provider behavior | Provider unit tests or a mocked API path; `nanobot agent -m "Hello!"` with safe config when possible |
-| Channel behavior | Channel tests plus `nanobot gateway` startup path |
-| WebUI behavior | WebUI tests/build and, for routing/settings/chat changes, browser-level verification through the gateway |
-| Tool behavior | Tool unit tests and an agent-run path when schema or model-facing behavior changes |
-| Docs | Link checks, command accuracy against CLI/schema, and `git diff --check` |
-
-For user-facing flows, prefer at least one verification path through the public surface the user actually touches: CLI command, HTTP endpoint, WebSocket/WebUI, chat channel, or packaged import.

 Connect nanobot to your favorite chat platform. Want to build your own? See the [Channel Plugin Guide](./channel-plugin-guide.md).
 
-Before configuring a chat app, make sure the local CLI path works:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-If that fails, fix installation, config, provider, or model setup first with [`quick-start.md`](./quick-start.md), [`providers.md`](./providers.md), and [`troubleshooting.md`](./troubleshooting.md). Chat apps require `nanobot gateway` to stay running after the channel is configured.
-
-Most examples below are snippets to merge into `~/.nanobot/config.json`.
-
-## Common Setup Pattern
-
-Every chat app uses the same shape:
-
-1. Create or prepare the bot/account in the chat platform.
-2. Copy the token, secret, QR login state, webhook URL, or account ID that platform gives you.
-3. Merge that platform's JSON snippet into `~/.nanobot/config.json`.
-4. Keep access control narrow at first with `allowFrom` or the platform-specific allow list.
-5. Check that nanobot can see the configured channel:
-
-```bash
-nanobot channels status
-```
-
-6. Start the gateway and leave that terminal running:
-
-```bash
-nanobot gateway
-```
-
-7. Send a message from the allowed account. In group chats, follow that channel's `groupPolicy` behavior: many channels default to mention-only, while Matrix and WhatsApp default to open group replies.
-
-If `nanobot channels status` does not show the channel as enabled, the config snippet is in the wrong place, the channel name is misspelled, or the config file you edited is not the one nanobot is reading. If the channel is enabled but messages do not arrive, run `nanobot gateway --verbose` and compare the platform-side credentials, event permissions, and allow lists.
-
-> `["*"]` allows anyone who can reach that channel to talk to the bot. Use it only when that is intentional, or temporarily while testing in a private sandbox.

-## Local triggers
-
-Use `/trigger <name>` when a local script or another service should be able to
-send a message into the current chat/session later. A name is required; plain
-`/trigger` only shows the usage hint.
-
-Create the trigger from the chat where future messages should arrive:
-
-```text
-/trigger PR review
-```
-
-nanobot replies with a trigger ID and a command shaped like:
-
-```bash
-nanobot trigger trg_8K4P2Q9X "Review PR #4502"
-```
-
-Replace `"Review PR #4502"` with the message you want nanobot to receive. The
-trigger is bound to the session where it was created, so the message goes back
-to that same chat. Keep `nanobot gateway` running so trigger messages can be
-delivered. The trigger message starts an automation turn recorded in that
-session with the message you passed to the CLI; it is not treated as a normal
-user message. If that session is already running a turn, the trigger waits
-until the session is idle instead of being injected into the active turn.
-
-Trigger deliveries are stored in the workspace until their linked agent turn
-finishes successfully. If the gateway exits after claiming a delivery but before
-the turn completes, the next gateway start requeues that delivery. This is an
-at-least-once local queue: a delivery may run more than once if the process
-exits at the wrong time, so external scripts should make repeated trigger
-messages safe. If the delivery reaches the agent and the agent turn fails, the
-delivery is marked failed in Automations instead of retrying forever.
-
-For longer or generated content, omit the message argument and pipe stdin:
-
-```bash
-printf '%s\n' "Review the latest failed CI job" | nanobot trigger trg_8K4P2Q9X
-```
-
-If an external webhook should wake nanobot up, run your own small webhook
-service and have it call the trigger command after it builds the final message:
-
-```bash
-nanobot trigger <trigger-id> "<message>"
-```
-
-If you run multiple nanobot instances, pass the same config or workspace
-selector used by the gateway:
-
-```bash
-nanobot trigger --config ./bot-a/config.json trg_8K4P2Q9X "Nightly report"
-nanobot trigger --workspace ./bot-a/workspace trg_8K4P2Q9X "Nightly report"
-```
-
-Manage triggers from the WebUI Automations view. You can search, pause/resume,
-rename, delete, and copy the trigger command there. A session may have multiple
-triggers, just like it may have multiple scheduled automations.
-
 ## Periodic Tasks
 
-Periodic background checks are driven by `HEARTBEAT.md` in your workspace (`~/.nanobot/workspace/HEARTBEAT.md`). When `nanobot gateway` starts, it registers a protected heartbeat cron job by default. Every 30 minutes, that job checks the file; if it finds tasks under `## Active Tasks`, the agent executes them and delivers only results that pass the notification gate to your most recently active chat channel. If there are no active tasks, or the result is routine with nothing useful to report, the heartbeat is skipped silently.
+The gateway wakes up every 30 minutes and checks `HEARTBEAT.md` in your workspace (`~/.nanobot/workspace/HEARTBEAT.md`). If the file has tasks under `## Active Tasks`, the agent executes them and delivers results to your most recently active chat channel. If there are no active tasks, the heartbeat is skipped silently.
-
-Use heartbeat for recurring checks that should usually stay quiet. User-created cron jobs are different: they run as scheduled turns in the chat/session where they were created and normally deliver the result back to that channel.
 
 **Setup:** edit `~/.nanobot/workspace/HEARTBEAT.md` (created automatically by `nanobot onboard`):
 
 ```markdown
 ## Active Tasks
 
-- Check weather forecast and notify me only if storms are expected
+- [ ] Check weather forecast and send a summary
-- Scan inbox for urgent emails and notify me if any are found
+- [ ] Scan inbox for urgent emails
 ```
 
-The agent can also manage this file itself - ask it to "add a periodic background check" or "check this periodically but only notify me if something changes" and it will update `HEARTBEAT.md` for you. Completed tasks should be deleted from the file, not moved to another section.
+The agent can also manage this file itself — ask it to "add a periodic task" and it will update `HEARTBEAT.md` for you. Completed tasks should be deleted from the file, not moved to another section.
-
-You can change the interval or disable the built-in heartbeat in `~/.nanobot/config.json`:
-
-```json
-{
-  "gateway": {
-    "heartbeat": {
-      "enabled": true,
-      "intervalS": 1800
-    }
-  }
-}
-```
-
-The heartbeat job is visible in `cron(action="list")` as `heartbeat`, but it is system-managed and cannot be removed with the `cron` tool. To stop it, set `gateway.heartbeat.enabled` to `false` and restart the gateway.
 
 > **Note:** The gateway must be running (`nanobot gateway`) and you must have chatted with the bot at least once so it knows which channel to deliver to.

-
-## Choose a Command
-
-| Goal | Command | Notes |
-|---|---|---|
-| Check the install | `nanobot --version` | If this fails, try `python -m nanobot --version` |
-| Create or refresh config | `nanobot onboard` | Creates `~/.nanobot/config.json` and `~/.nanobot/workspace/` |
-| Use guided setup | `nanobot onboard --wizard` | Best when you prefer prompts over hand-editing JSON |
-| Check config without calling a model | `nanobot status` | Reads the default config and summarizes the active model/provider |
-| Send one test message | `nanobot agent -m "Hello!"` | First proof that install, config, provider, model, and workspace all work |
-| Chat in the terminal | `nanobot agent` | Interactive local chat; exit with `exit`, `/exit`, `:q`, or `Ctrl+D` |
-| Use WebUI or chat apps | `nanobot gateway` | Keep this terminal running, or use `nanobot gateway --background` |
-| Deliver a local trigger | `nanobot trigger <id> "message"` | Created first with `/trigger <name>` in the target chat/session |
-| Serve an OpenAI-compatible API | `nanobot serve` | Starts `/v1/chat/completions`, `/v1/models`, and `/health` |
-| Check chat channel setup | `nanobot channels status` | Useful before starting `nanobot gateway` |
-| Log in to QR/OAuth-style channels | `nanobot channels login <channel>` | Used by channels such as WhatsApp and WeChat |
-| Log in to OAuth model providers | `nanobot provider login <provider>` | Used by OAuth providers such as OpenAI Codex and GitHub Copilot |
-
-## Global
-
-```bash
-nanobot --help
-nanobot --version
-python -m nanobot --help
-python -m nanobot --version
-```
-
-`python -m nanobot ...` is useful when the package is installed but the `nanobot` script is not on `PATH`.
-
-## Common Patterns
-
-Most day-to-day commands use the default config and workspace. Advanced or multi-instance runs usually pass both paths explicitly:
-
-```bash
-nanobot agent --config ./bot-a/config.json --workspace ./bot-a/workspace -m "Hello"
-nanobot gateway --config ./bot-a/config.json --workspace ./bot-a/workspace
-nanobot serve --config ./bot-a/config.json --workspace ./bot-a/workspace
-```
-
-Use `--verbose` on long-running processes when you need startup or runtime logs:
-
-```bash
-nanobot gateway --verbose
-nanobot serve --verbose
-```
-
-Long-running commands keep working until you stop them. Press `Ctrl+C` in that terminal
-to stop foreground `nanobot gateway` or `nanobot serve`. If you started the gateway
-with `--background`, use `nanobot gateway stop`.

-
-## Gateway
-
-`nanobot gateway` starts enabled chat channels, WebUI/WebSocket when configured, cron-backed system jobs, Dream, heartbeat, and the health endpoint. By default it runs in the foreground, which keeps existing scripts and terminal workflows unchanged. Use `--background` when you want a local macOS, Linux, or Windows process that you can manage from the CLI.
-
-| Command | Description |
-|---|---|
-| `nanobot gateway` | Start the gateway in the foreground with config defaults |
-| `nanobot gateway --verbose` | Show verbose runtime output |
-| `nanobot gateway --port <port>` | Override `gateway.port` for the health endpoint |
-| `nanobot gateway --workspace <path>` | Override workspace |
-| `nanobot gateway --config <path>` | Use a specific config file |
-| `nanobot gateway --background` | Start the gateway as a background process |
-| `nanobot gateway status` | Show the recorded background gateway PID, state file, and log file |
-| `nanobot gateway logs --no-follow` | Print recent background gateway logs and exit |
-| `nanobot gateway logs` | Follow background gateway logs |
-| `nanobot gateway restart` | Restart the recorded background gateway with the current config |
-| `nanobot gateway stop` | Stop the recorded background gateway |
-| `nanobot gateway install-service` | Install a systemd user service or macOS LaunchAgent |
-| `nanobot gateway install-service --dry-run` | Preview the generated service file and system commands |
-| `nanobot gateway uninstall-service` | Remove the installed system service |
-
-For custom instances, pass the same selector flags to management commands:
-
-```bash
-nanobot gateway --background --config ./bot-a/config.json --workspace ./bot-a/workspace
-nanobot gateway status --config ./bot-a/config.json --workspace ./bot-a/workspace
-nanobot gateway stop --config ./bot-a/config.json --workspace ./bot-a/workspace
-nanobot gateway install-service --config ./bot-a/config.json --workspace ./bot-a/workspace --name bot-a
-```
-
-`--background` is a lightweight detached process. `install-service` is for
-login/startup integration: Linux uses a systemd user service; macOS uses a
-LaunchAgent plist. System services run the foreground gateway under the OS
-supervisor rather than nesting another background process.
-
-Default health endpoint:
-
-```text
-http://127.0.0.1:18790/health
-```
-
-The bundled WebUI is served by the WebSocket channel, usually on port `8765`, not by the gateway health endpoint.
-
-## Local Triggers
-
-`nanobot trigger` delivers one local message to a trigger that was created from
-a chat/session with `/trigger <name>`.
-
-```bash
-nanobot trigger trg_8K4P2Q9X "Review PR #4502"
-```
-
-Keep `nanobot gateway` running so the message can be delivered to the linked
-chat/session. The message is recorded as an automation turn in that session,
-not as a normal chat message typed by the user.
-
-The command writes to a workspace-local durable queue. If `nanobot gateway` is
-not running yet, the message waits in that workspace. If the target session is
-already running a turn, the trigger waits for that session to become idle. If the
-gateway exits after claiming a delivery but before the linked turn completes,
-the next gateway start requeues that delivery. The queue is at-least-once, not
-exactly-once, so the same message can be delivered again after an interrupted
-process. If the agent receives the delivery and the turn fails, the delivery is
-marked failed instead of retried indefinitely. Each delivery also writes an
-audit record under `<workspace>/triggers/runs`. Run one gateway consumer per
-workspace; this local queue is not a distributed multi-consumer queue.
-
-Use stdin when another local process generates the message:
-
-```bash
-generate-report | nanobot trigger trg_8K4P2Q9X
-```
-
-Options:
-
-| Command | Description |
-|---|---|
-| `nanobot trigger <id> "message"` | Deliver one message through a trigger |
-| `nanobot trigger <id>` | Read the message from stdin |
-| `nanobot trigger --config <path> <id> "message"` | Use the workspace from a specific config |
-| `nanobot trigger --workspace <path> <id> "message"` | Use a specific workspace |
-
-Triggers are managed in the WebUI Automations view instead of through separate
-`list`, `revoke`, or `delete` CLI subcommands. From there you can pause/resume,
-rename, delete, search, and copy the command for each trigger.
-
-For webhooks or other external systems, run your own small service and have it
-call this CLI after it decides what message nanobot should receive.

-
-## Runtime Shape
-
-nanobot has one small core loop and several ways to enter it:
-
-| Part | What it does |
-|---|---|
-| Agent loop | Builds context, selects the session, calls the provider, runs tools, and publishes replies |
-| Providers | LLM backends such as OpenRouter, Anthropic, OpenAI, Bedrock, Ollama, vLLM, and other OpenAI-compatible APIs |
-| Channels | User-facing transports such as CLI, WebUI/WebSocket, Telegram, Discord, Slack, Feishu, WeChat, Email, and others |
-| Tools | Capabilities the model may call, including files, shell, web search/fetch, MCP, cron, image generation, and subagents |
-| Memory | Workspace files and session history that keep useful context across turns |
-| Gateway | Long-running process that connects enabled channels and serves the health endpoint |
-
-The simplest path is `nanobot agent -m "Hello!"`: one inbound message goes through the agent loop and prints the reply in your terminal. The long-running path is `nanobot gateway`: channels receive messages from chat apps or the WebUI, publish them to the same agent loop, and send replies back to the originating channel.
-
-## Config vs Workspace
-
-The default instance lives under `~/.nanobot/`:
-
-| Path | Meaning |
-|---|---|
-| `~/.nanobot/config.json` | Instance configuration: providers, model defaults, channels, tools, gateway, API, and runtime options |
-| `~/.nanobot/workspace/` | Agent workspace: memory, sessions, heartbeat tasks, cron jobs, skills, and generated artifacts |
-
-You can override both with command flags:
-
-```bash
-nanobot onboard --config ./bot-a/config.json --workspace ./bot-a/workspace
-nanobot agent --config ./bot-a/config.json --workspace ./bot-a/workspace -m "Hello"
-nanobot gateway --config ./bot-a/config.json --workspace ./bot-a/workspace
-```
-
-The config file controls what nanobot may use. The workspace is where nanobot keeps state for that instance.
-
-## Config Format
-
-`config.json` accepts both camelCase and snake_case keys. The docs use camelCase because nanobot writes config back to disk with camelCase aliases, for example `apiKey`, `modelPresets`, `intervalS`, and `maxToolResultChars`.
-
-Most examples are partial snippets. Merge them into the existing file created by `nanobot onboard`; do not replace the whole file unless you want to reset the instance.
-
-## One Agent Turn
-
-A normal turn follows this flow:
-
-1. A channel receives a user message and publishes it to the message bus.
-2. The agent loop chooses a session key and builds context from the workspace, skills, memory, recent messages, channel metadata, and runtime settings.
-3. The provider receives the model request.
-4. If the model asks for tools, the runner executes them and feeds results back to the model.
-5. The final reply is saved to the session and sent back through the channel.
-
-That flow is the same whether the message starts in the CLI, WebUI, Telegram, Discord, or another channel.
-
-## CLI, Gateway, API, and WebUI
-
-| Entry point | Command | Use it for |
-|---|---|---|
-| CLI one-shot | `nanobot agent -m "..."` | First-run checks, scripts, and quick local questions |
-| CLI interactive | `nanobot agent` | Terminal chat with persistent session history |
-| Gateway | `nanobot gateway` | Chat apps, WebUI, heartbeat, Dream, and long-running service mode |
-| OpenAI-compatible API | `nanobot serve` | Programmatic access through `/v1/chat/completions` |
-| WebUI | `nanobot gateway` plus WebSocket channel | Browser workbench served by the WebSocket channel on port `8765` |
-
-The gateway health endpoint is on `gateway.port` (`18790` by default). The browser WebUI is served by the WebSocket channel (`8765` by default), not by the health endpoint.
-
-## Provider and Model Selection
-
-The active model should normally come from a named `modelPresets` entry selected by `agents.defaults.modelPreset`. Direct `agents.defaults.provider` and `agents.defaults.model` still form the implicit `default` preset for older or minimal configs. The active provider is resolved in this order:
-
-1. If the active preset provider or implicit default provider is not `"auto"`, nanobot uses that provider.
-2. If provider is `"auto"`, nanobot tries to infer the provider from the model name, configured API keys, local provider base URLs, or gateway providers.
-3. OAuth providers such as OpenAI Codex and GitHub Copilot require explicit login and explicit provider/model selection inside the active preset.
-
-Pin the provider inside the preset when setting up for the first time. It is easier to debug:
-
-```json
-{
-  "modelPresets": {
-    "primary": {
-      "provider": "openrouter",
-      "model": "anthropic/claude-opus-4.5"
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-See [`providers.md`](./providers.md) for practical examples and [`configuration.md#providers`](./configuration.md#providers) for the full provider reference.
-
-## Channels and Sessions
-
-Each channel maps inbound messages to a session key. That lets independent conversations keep separate history. The WebUI also supports multiple chats and workspace-scoped metadata for project workspaces.
-
-`agents.defaults.unifiedSession` can intentionally share one session across channels for a single-user multi-device setup. Leave it off if you expect separate people, groups, channels, or projects to keep separate context.
-
-## Memory, Sessions, and Dream
-
-nanobot uses two related stores:
-
-| Store | Location | Purpose |
-|---|---|---|
-| Sessions | `<workspace>/sessions/*.jsonl` | Recent conversation turns replayed into context |
-| Memory | `<workspace>/memory/MEMORY.md` and `<workspace>/memory/history.jsonl` | Long-term facts and consolidated history |
-
-Dream is a periodic consolidation job. It reads accumulated history and updates workspace memory so useful context can survive beyond short session replay.
-
-See [`memory.md`](./memory.md) for the detailed design.
-
-## Tools and Safety
-
-Tools are discovered automatically from built-in modules and plugin entry points. Common tool groups include:
-
-- file read/write/edit and patching;
-- shell execution with configurable sandboxing;
-- web search and web fetch with SSRF checks;
-- MCP servers;
-- cron reminders, local triggers, and heartbeat tasks;
-- image generation;
-- subagents and runtime self-inspection.
-
-Security-sensitive controls live in [`configuration.md#security`](./configuration.md#security). For production or shared chat apps, also configure channel access controls such as `allowFrom`, pairing, or WebSocket tokens.
-
-## Background Jobs
-
-When `nanobot gateway` starts, it runs workspace-scoped automations and
-registers system jobs:
-
-- `dream`, when `agents.defaults.dream.enabled` is true;
-- `heartbeat`, when `gateway.heartbeat.enabled` is true.
-
-Heartbeat reads `<workspace>/HEARTBEAT.md`. If the file has tasks under `## Active Tasks`, nanobot executes them and sends only useful/actionable results to the most recently active chat target. Routine "nothing changed" results are suppressed.
-
-User-created reminders use the same cron service but are not the same as the
-protected heartbeat system job. They run as scheduled turns in their origin
-chat/session and normally deliver the result back to that channel.
-
-Local triggers are also session-bound, but they do not have their own
-schedule. Create one from the target chat with `/trigger <name>`, then call
-`nanobot trigger <id> "<message>"` when a local script or external service wants
-nanobot to respond in that session. Webhook servers, third-party auth, and
-event-to-message formatting stay outside nanobot. Trigger deliveries are stored
-in the workspace until the linked agent turn finishes successfully. If the
-target session is busy, the trigger waits until that session is idle instead of
-being injected into the active turn. The message is recorded as an automation
-turn in that session. Delivery is at-least-once, so external systems should
-tolerate repeated trigger messages; a delivery that reaches the agent but fails
-is marked failed rather than retried forever.

 # Deployment
 
-Use this page after `nanobot agent -m "Hello!"` works locally. Deployment keeps long-running surfaces online: WebUI, chat apps, heartbeat, Dream, cron jobs, and channel connections.
-
-## Before You Deploy
-
-Check these once before Docker, systemd, or LaunchAgent:
-
-| Check | Why it matters |
-|---|---|
-| `nanobot status` shows the expected config and workspace | Confirms the process will read the instance you meant to run |
-| `nanobot agent -m "Hello!"` works | Proves install, config, provider, model, and workspace writes before adding a service layer |
-| Secrets are in environment variables or protected config files | API keys, bot tokens, OAuth state, and chat credentials should not be world-readable |
-| `~/.nanobot/` or your custom config/workspace path is persistent | Sessions, memory, channel login state, generated artifacts, and cron jobs live there |
-| Channel access control is intentional | Use `allowFrom`, pairing, WebSocket `token`/`tokenIssueSecret`, or private test channels before exposing the bot |
-| Ports are planned | Gateway health defaults to `18790`; WebUI/WebSocket defaults to `8765`; `nanobot serve` defaults to `8900` |
-| Logs are easy to reach | Use `docker compose logs`, `journalctl`, LaunchAgent log files, or `nanobot gateway --verbose` while diagnosing startup |
-
-Restart the deployed process after editing `config.json`. Long-running processes read config at startup.
-
-## Choose a Runtime
-
-| Runtime | Use it for | State location | Useful first command |
-|---|---|---|---|
-| Docker Compose | Repeatable container runs on Linux servers or workstations | Bind-mount `~/.nanobot` to `/home/nanobot/.nanobot` | `docker compose run --rm nanobot-cli agent -m "Hello!"` |
-| Docker CLI | Manual container testing or small one-off hosts | Bind-mount `~/.nanobot` to `/home/nanobot/.nanobot` | `docker run -v ~/.nanobot:/home/nanobot/.nanobot --rm nanobot status` |
-| systemd user service | Linux user-level gateway that restarts automatically | Host user's `~/.nanobot` unless you pass explicit paths | `systemctl --user status nanobot-gateway` |
-| macOS LaunchAgent | macOS gateway that starts after login | Host user's `~/.nanobot` unless the plist passes explicit paths | `launchctl list | grep ai.nanobot.gateway` |

-# Development
-
-This page collects contributor-facing notes for extending nanobot. User-facing setup and runtime options live in [`configuration.md`](./configuration.md).
-
-## Adding an LLM Provider
-
-nanobot uses the provider registry in `nanobot/providers/registry.py` as the source of truth for LLM provider metadata. Most OpenAI-compatible providers need only two changes.
-
-1. Add a `ProviderSpec` entry to `PROVIDERS`:
-
-```python
-ProviderSpec(
-    name="myprovider",
-    keywords=("myprovider", "mymodel"),
-    env_key="MYPROVIDER_API_KEY",
-    display_name="My Provider",
-    default_api_base="https://api.myprovider.com/v1",
-)
-```
-
-2. Add a field to `ProvidersConfig` in `nanobot/config/schema.py`:
-
-```python
-class ProvidersConfig(BaseModel):
-    ...
-    myprovider: ProviderConfig = Field(default_factory=ProviderConfig)
-```
-
-Environment variables, config matching, provider status, and WebUI credential display derive from those two entries.
-
-Useful `ProviderSpec` options:
-
-| Field | Description |
-|---|---|
-| `default_api_base` | Default OpenAI-compatible base URL. |
-| `env_extras` | Additional environment variables derived from the provider config. |
-| `model_overrides` | Per-model request parameter overrides. |
-| `is_gateway` | Provider can route many model families, like OpenRouter. |
-| `detect_by_key_prefix` | Match configured gateways by API-key prefix. |
-| `detect_by_base_keyword` | Match configured gateways by API base URL. |
-| `strip_model_prefix` | Strip `provider/` before sending the model to the upstream API. |
-| `supports_max_completion_tokens` | Use `max_completion_tokens` instead of `max_tokens`. |
-| `is_transcription_only` | Provider has credentials but cannot serve chat completions. |
-
-## Adding a Transcription Provider
-
-Transcription is intentionally split into two layers:
-
-- `nanobot/audio/transcription_registry.py` owns provider names, aliases, default models, and adapter loading.
-- `nanobot/providers/transcription.py` owns provider-specific HTTP behavior.
-
-Credentials still live under `providers.<provider>` so chat channels and WebUI resolve API keys and API bases the same way.
-
-1. Add provider credentials to `ProvidersConfig`.
-
-```python
-class ProvidersConfig(BaseModel):
-    ...
-    my_stt: ProviderConfig = Field(default_factory=ProviderConfig)
-```
-
-2. Add a `ProviderSpec` in `nanobot/providers/registry.py`.
-
-For transcription-only providers, set `is_transcription_only=True` so they show up in credential/settings surfaces but stay out of chat model selection.
-
-```python
-ProviderSpec(
-    name="my_stt",
-    keywords=("my_stt",),
-    env_key="MY_STT_API_KEY",
-    display_name="My STT",
-    default_api_base="https://api.example.com/v1",
-    is_transcription_only=True,
-)
-```
-
-3. Add an adapter class in `nanobot/providers/transcription.py`.
-
-Adapters receive resolved credentials and settings. They return an empty string for provider errors so channel voice messages fail quietly instead of crashing the agent loop.
-
-```python
-class MySTTTranscriptionProvider:
-    def __init__(
-        self,
-        api_key: str | None = None,
-        api_base: str | None = None,
-        language: str | None = None,
-        model: str | None = None,
-    ):
-        self.api_key = api_key or os.environ.get("MY_STT_API_KEY")
-        self.api_base = api_base or "https://api.example.com/v1"
-        self.language = language or None
-        self.model = model or "my-default-stt-model"
-
-    async def transcribe(self, file_path: str | Path) -> str:
-        ...
-```
-
-4. Register the adapter in `nanobot/audio/transcription_registry.py`.
-
-```python
-TranscriptionProviderSpec(
-    name="my_stt",
-    default_model="my-default-stt-model",
-    adapter="nanobot.providers.transcription:MySTTTranscriptionProvider",
-    aliases=("mystt",),
-)
-```
-
-5. Add tests.
-
-At minimum, cover:
-
-- config resolution in `tests/providers/test_transcription.py`
-- adapter request/response behavior and retry/error handling
-- WebUI settings payload/update behavior in `tests/webui/test_settings_api.py`
-- provider brand mapping if the provider appears in Settings
-
-6. Update user-facing docs.
-
-Add the provider to [`configuration.md`](./configuration.md) where users choose `transcription.provider`, but keep implementation details in this development guide.

-
-```text
-POST /v1/images/generations
-```
-
-The response must include generated images in `data[].b64_json` or `data[].url`. Native prediction APIs, such as Replicate's `/v1/models/{owner}/{model}/predictions`, are not directly compatible unless you put an OpenAI-compatible gateway in front of them.

-}
-```
-
-The `apiBase` is required. The provider sends requests to `{apiBase}/images/generations` using the OpenAI Images API format with `response_format: "b64_json"`. The `apiKey` is optional for local or unauthenticated endpoints. Reference-image edits are not supported by the generic `custom` provider.
-
-`extraBody` can adapt provider-specific quirks because it is merged last into the request body. Examples:
-
-- Agnes AI documents URL responses, so use `"extraBody": {"response_format": "url"}`.
-- Together AI documents `"response_format": "base64"`, so override the default.
-- Volcengine Ark Seedream models may require size hints such as `"2K"`, `"3K"`, `"4K"`, or explicit dimensions. Set `tools.imageGeneration.defaultImageSize` or `providers.custom.extraBody.size` to a value supported by the selected model.
-
-For compatibility with the default nanobot setting, custom maps `defaultImageSize: "1K"` to `1024x1024`. Other explicit size hints are passed through unchanged.

-
-## Choose a Recipe
-
-Match the recipe to the credential or endpoint you already have:
-
-| What you have | Recipe | Must match |
-|---|---|---|
-| A gateway key and model IDs that include a model family path, such as `provider/model-name` | [OpenRouter Gateway](#recipe-openrouter-gateway) | API key, provider config key, preset provider, and gateway model ID |
-| An OpenCode Zen or Go key | [OpenCode Zen or Go](#recipe-opencode-zen-or-go) | `OPENCODE_API_KEY`, the Zen/Go provider key, and a model ID from the matching OpenCode endpoint |
-| An OpenAI platform API key and OpenAI model ID | [OpenAI Direct](#recipe-openai-direct) | `OPENAI_API_KEY`, `provider: "openai"`, and an OpenAI model available to that account |
-| An Anthropic API key and Anthropic model ID | [Anthropic Direct](#recipe-anthropic-direct) | `ANTHROPIC_API_KEY`, `provider: "anthropic"`, and a non-gateway model ID |
-| A Kimi Coding Plan key | [Kimi Coding Plan](#recipe-kimi-coding-plan) | `KIMI_CODING_API_KEY`, `provider: "kimi_coding"`, and `model: "kimi-for-coding"` |
-| An OpenAI-compatible `/v1` endpoint that is not a named nanobot provider | [Custom OpenAI-Compatible Provider](#recipe-custom-openai-compatible-provider) | `apiBase`, optional API key, and the model ID served by that endpoint |
-| Ollama already running locally | [Ollama Local Model](#recipe-ollama-local-model) | Ollama `apiBase`, pulled model name, and local server availability |
-| vLLM, LM Studio, or another local OpenAI-compatible server | [vLLM or LM Studio](#recipe-vllm-or-lm-studio) | Local `/v1` base URL, any required key, and served model name |

-| A working agent and a Langfuse project | [Langfuse Tracing](#recipe-langfuse-tracing) | Langfuse env vars in the same process environment that starts nanobot |
-
-## How to Use a Recipe
-
-1. Install nanobot and run `nanobot onboard` once so `~/.nanobot/config.json` exists. Use `nanobot onboard --wizard` if you prefer prompts over hand-editing JSON.
-2. Put secrets in environment variables when possible.
-3. Merge the recipe snippet into `~/.nanobot/config.json`.
-4. Run `nanobot status`.
-5. Run `nanobot agent -m "Hello!"`.
-6. If the CLI works, then connect WebUI, gateway, or chat apps.
-
-The active model should normally come from `agents.defaults.modelPreset`, and that name should point to an entry in `modelPresets`. Direct `agents.defaults.provider` and `agents.defaults.model` still work for older configs, but presets are easier to switch and easier to reuse as fallbacks.
-
-## Secret Setup
-
-Environment variables keep API keys out of the config file.
-
-Use the variable name shown by the recipe you picked. The commands below use `OPENROUTER_API_KEY` only as an example; an OpenAI direct recipe uses `OPENAI_API_KEY`, an Anthropic direct recipe uses `ANTHROPIC_API_KEY`, and a custom endpoint can use any variable name you reference in `config.json`.
-
-**macOS / Linux**
-
-```bash
-export OPENROUTER_API_KEY="sk-or-v1-..."
-nanobot agent -m "Hello!"
-```
-
-**Windows PowerShell**
-
-```powershell
-$env:OPENROUTER_API_KEY = "sk-or-v1-..."
-nanobot agent -m "Hello!"
-```
-
-Environment variables set this way apply only to the current terminal. For long-running services such as systemd, Docker, LaunchAgent, or a remote shell, set the variables in that service environment before starting nanobot.
-
-## Recipe: OpenRouter Gateway
-
-This recipe applies when one API key routes many hosted model families.
-
-```json
-{
-  "providers": {
-    "openrouter": {
-      "apiKey": "${OPENROUTER_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "Primary",
-      "provider": "openrouter",
-      "model": "anthropic/claude-sonnet-4.5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Verify:
-
-```bash
-nanobot status
-nanobot agent -m "Hello!"
-```
-
-If this fails with `401` or `unauthorized`, check that `OPENROUTER_API_KEY` is visible in the same terminal or service that starts nanobot. If it fails with `model not found`, choose a model ID that OpenRouter lists for your account.
-
-## Recipe: OpenCode Zen or Go
-
-This recipe applies when your credential comes from OpenCode Zen or OpenCode Go.
-Both providers use `OPENCODE_API_KEY`; pick the provider block that matches the
-subscription or balance you want to use.
-
-OpenCode Zen:
-
-```json
-{
-  "providers": {
-    "opencodeZen": {
-      "apiKey": "${OPENCODE_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "OpenCode Zen",
-      "provider": "opencode_zen",
-      "model": "opencode/deepseek-v4-pro",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-OpenCode Go:
-
-```json
-{
-  "providers": {
-    "opencodeGo": {
-      "apiKey": "${OPENCODE_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "OpenCode Go",
-      "provider": "opencode_go",
-      "model": "opencode-go/deepseek-v4-flash",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Verify:
-
-```bash
-nanobot status
-nanobot agent -m "Hello!"
-```
-
-OpenCode's docs list models across multiple endpoint types. The `opencode_zen`
-and `opencode_go` providers in nanobot use the OpenAI-compatible
-`chat/completions` path. If a model fails with `model not found` or an endpoint
-shape error, choose a model that OpenCode lists under `chat/completions` for the
-matching Zen or Go endpoint.
-
-## Recipe: OpenAI Direct
-
-This recipe applies when you have an OpenAI API key and want to call OpenAI directly instead of through a gateway.
-
-```json
-{
-  "providers": {
-    "openai": {
-      "apiKey": "${OPENAI_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "OpenAI",
-      "provider": "openai",
-      "model": "gpt-5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 128000,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Verify:
-
-```bash
-OPENAI_API_KEY="sk-..." nanobot agent -m "Hello!"
-```
-
-If your shell cannot use inline environment variables, set `OPENAI_API_KEY` first and then run `nanobot agent -m "Hello!"`. If the provider rejects `apiType`, remove `apiType` unless you are using a documented OpenAI-specific mode.
-
-## Recipe: Anthropic Direct
-
-This recipe applies when your key comes from Anthropic and your model name is an Anthropic model ID, not an OpenRouter model path.
-
-```json
-{
-  "providers": {
-    "anthropic": {
-      "apiKey": "${ANTHROPIC_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "Anthropic",
-      "provider": "anthropic",
-      "model": "claude-sonnet-4-5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 200000,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Verify:
-
-```bash
-ANTHROPIC_API_KEY="sk-ant-..." nanobot agent -m "Hello!"
-```
-
-If you copied a model name such as `anthropic/claude-sonnet-4.5`, that is a gateway-style model path and belongs under `provider: "openrouter"`, not `provider: "anthropic"`.
-
-If you use an Anthropic-compatible proxy, keep the preset provider as `anthropic` and set `providers.anthropic.apiBase`:
-
-```json
-{
-  "providers": {
-    "anthropic": {
-      "apiKey": "${ANTHROPIC_API_KEY}",
-      "apiBase": "https://anthropic-proxy.example.com"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "Anthropic proxy",
-      "provider": "anthropic",
-      "model": "claude-sonnet-4-5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 200000,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Do not configure Anthropic-compatible endpoints as arbitrary custom provider names; named custom providers use the OpenAI-compatible request format.
-
-## Recipe: Kimi Coding Plan
-
-This recipe applies when your key comes from Kimi's Coding Plan endpoint. Nanobot uses a dedicated `kimi_coding` provider for this Anthropic Messages API endpoint; do not configure it as a generic `custom` provider.
-
-```json
-{
-  "providers": {
-    "kimiCoding": {
-      "apiKey": "${KIMI_CODING_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "kimiCoding": {
-      "label": "Kimi Coding",
-      "provider": "kimi_coding",
-      "model": "kimi-for-coding",
-      "maxTokens": 4096,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "kimiCoding"
-    }
-  }
-}
-```
-
-Verify:
-
-```bash
-nanobot status
-nanobot agent -m "Hello!"
-```
-
-The default base URL is `https://api.kimi.com/coding/v1`. This endpoint requires a Claude-compatible `User-Agent`; nanobot sends `claude-code/0.1.0` by default. If your account requires a different value, override it with `providers.kimiCoding.extraHeaders.User-Agent`.
-
-## Recipe: Custom OpenAI-Compatible Provider
-
-This recipe applies to an OpenAI-compatible service that is not a named nanobot provider.
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "${CUSTOM_API_KEY}",
-      "apiBase": "https://api.example.com/v1"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "Custom",
-      "provider": "custom",
-      "model": "provider-model-name",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Verify the endpoint before blaming nanobot:
-
-```bash
-curl -sS https://api.example.com/v1/models
-nanobot agent -m "Hello!"
-```
-
-`apiBase` is the HTTP base URL, not the model name. Include the version path when the service expects it, such as `/v1`. If the service requires a non-empty key but does not validate it, use a placeholder such as `"apiKey": "EMPTY"`.
-
-For multiple custom endpoints, do not overload the single `custom` block. Name each endpoint under `providers` and reference that same name from the preset:
-
-```json
-{
-  "providers": {
-    "workProxy": {
-      "apiKey": "${WORK_PROXY_API_KEY}",
-      "apiBase": "https://proxy.example.com/v1"
-    },
-    "lab-local": {
-      "apiBase": "http://127.0.0.1:8000/v1"
-    }
-  },
-  "modelPresets": {
-    "work": {
-      "label": "Work proxy",
-      "provider": "workProxy",
-      "model": "gpt-4o-mini",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    },
-    "lab": {
-      "label": "Lab local",
-      "provider": "lab-local",
-      "model": "served-model-name",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "work"
-    }
-  }
-}
-```
-
-These custom names behave like direct OpenAI-compatible providers: `apiBase` is required, `apiKey` is optional when the endpoint allows anonymous or placeholder credentials, and `apiType` should be left unset. They do not support Anthropic-compatible endpoints; use the `anthropic` provider with `apiBase` for that case.
-
-## Recipe: Ollama Local Model
-
-This recipe applies when Ollama is already installed and the model has been pulled locally.
-
-```bash
-ollama serve
-ollama pull llama3.2
-```
-
-```json
-{
-  "providers": {
-    "ollama": {
-      "apiBase": "http://localhost:11434/v1"
-    }
-  },
-  "modelPresets": {
-    "local": {
-      "label": "Local",
-      "provider": "ollama",
-      "model": "llama3.2",
-      "maxTokens": 2048,
-      "contextWindowTokens": 32768,
-      "temperature": 0.2
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "local"
-    }
-  }
-}
-```
-
-Verify:
-
-```bash
-curl -sS http://localhost:11434/v1/models
-nanobot agent -m "Hello!"
-```
-
-If you see `connection refused`, Ollama is not running or `apiBase` points to the wrong port. If the response is very slow, try a smaller local model or lower `contextWindowTokens`.
-
-## Recipe: vLLM or LM Studio
-
-This recipe applies when a local server exposes an OpenAI-compatible `/v1` API.
-
-```json
-{
-  "providers": {
-    "vllm": {
-      "apiBase": "http://127.0.0.1:8000/v1",
-      "apiKey": "EMPTY"
-    }
-  },
-  "modelPresets": {
-    "local": {
-      "label": "Local",
-      "provider": "vllm",
-      "model": "served-model-name",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.2
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "local"
-    }
-  }
-}
-```
-
-For LM Studio, use its local base URL and provider name:
-
-```json
-{
-  "providers": {
-    "lmStudio": {
-      "apiBase": "http://localhost:1234/v1"

-      "model": "local-model",
-      "maxTokens": 2048,
-      "contextWindowTokens": 32768
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "local"
-    }
-  }
-}
-```
-
-The config key can be `lmStudio` or `lm_studio`, but the preset provider should use the registry name `lm_studio`.
-
-## Recipe: Fallback Presets
-
-This recipe applies when one provider sometimes rate-limits, one model is expensive, or you want a local backup.
-
-```json
-{
-  "modelPresets": {
-    "fast": {
-      "label": "Fast",
-      "provider": "openrouter",
-      "model": "anthropic/claude-sonnet-4.5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    },
-    "deep": {
-      "label": "Deep",
-      "provider": "anthropic",
-      "model": "claude-sonnet-4-5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 200000,
-      "temperature": 0.1
-    },
-    "local": {
-      "label": "Local",
-      "provider": "ollama",
-      "model": "llama3.2",
-      "maxTokens": 2048,
-      "contextWindowTokens": 32768,
-      "temperature": 0.2
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "fast",
-      "fallbackModels": ["deep", "local"]
-    }
-  }
-}
-```
-
-`fallbackModels` belongs under `agents.defaults`. String entries are preset names, not raw model names. nanobot tries the active preset first, then the fallback presets in order.
-
-Keep fallback candidates realistic. If the local fallback has a smaller context window, nanobot must build context that fits the smallest window in the active chain.
-
-## Recipe: Langfuse Tracing
-
-This recipe applies after the agent works and you want observability for OpenAI-compatible provider calls.
-
-Install the optional package in the same Python environment that runs nanobot:
-
-```bash
-python -m pip install langfuse
-```
-
-Set the environment variables before starting nanobot:
-
-```bash
-export LANGFUSE_SECRET_KEY="sk-lf-..."
-export LANGFUSE_PUBLIC_KEY="pk-lf-..."
-export LANGFUSE_BASE_URL="https://cloud.langfuse.com"
-nanobot agent -m "Hello!"
-```
-
-PowerShell:
-
-```powershell
-$env:LANGFUSE_SECRET_KEY = "sk-lf-..."
-$env:LANGFUSE_PUBLIC_KEY = "pk-lf-..."
-$env:LANGFUSE_BASE_URL = "https://cloud.langfuse.com"
-nanobot agent -m "Hello!"
-```
-
-Langfuse is not a model provider in `config.json`. It is configured through environment variables and traces supported OpenAI-compatible provider calls. Native providers that do not use that client path may not produce Langfuse OpenAI-wrapper traces.
-
-## Recipe: Switch Models at Runtime
-
-Use this after you have more than one preset and are chatting through a supported channel.
-
-```json
-{
-  "modelPresets": {
-    "fast": {
-      "label": "Fast",
-      "provider": "openrouter",
-      "model": "anthropic/claude-sonnet-4.5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536
-    },
-    "local": {
-      "label": "Local",
-      "provider": "ollama",
-      "model": "llama3.2",
-      "maxTokens": 2048,
-      "contextWindowTokens": 32768
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "fast"
-    }
-  }
-}
-```
-
-In chat:
-
-```text
-/model
-/model local
-/model fast
-```
-
-`/model` switching is runtime-only. It does not rewrite `config.json`, and an in-progress turn keeps using the model it started with.
-
-## Quick Failure Map
-
-| Symptom | Usually means | First check |
-|---|---|---|
-| `401`, `unauthorized`, or `invalid API key` | The key is missing, wrong, expired, or under the wrong provider | Print or re-set the environment variable in the same terminal or service |
-| `model not found` | The model ID does not belong to the selected provider or gateway | Compare `modelPresets.<name>.provider` and `modelPresets.<name>.model` |
-| `connection refused` | Local server is not running or `apiBase` has the wrong port/path | Run `curl <apiBase>/models` |
-| `provider not found` | Provider name is misspelled or uses the config key instead of registry name | Use names such as `openrouter`, `openai`, `anthropic`, `ollama`, `vllm`, `lm_studio` |
-| Langfuse shows no traces | Env vars are missing, `langfuse` is not installed in the active Python environment, or the provider path is native | Run `python -m pip show langfuse` and restart nanobot from the same environment |

-# Providers and Models
-
-Use this page when the first reply fails because of provider/model mismatch, or when you want to adapt the concrete setup example to a different provider. If you already know which provider you want and only need a pasteable setup, use [`provider-cookbook.md`](./provider-cookbook.md).
-
-For every setup, answer three questions:
-
-1. Which provider owns the credential or endpoint?
-2. What model name does that provider expect?
-3. Does the provider need `apiKey`, `apiBase`, OAuth login, cloud credentials, or only a local server URL?
-
-Prefer a named `modelPresets` entry for the model/provider pair, then select it with `agents.defaults.modelPreset`. Direct `agents.defaults.provider` and `agents.defaults.model` still work for existing configs, but presets make runtime `/model` switching and fallback chains clearer. Pin `provider` inside the preset while setting up; you can switch back to `"auto"` later.
-
-## Choose a Provider Without Guessing
-
-The docs show concrete provider names so the JSON is copyable, not because nanobot ranks providers. Start from the service or endpoint you actually control:
-
-| If you have... | Configure... |
-|---|---|
-| An API key from a hosted provider or gateway | That provider's `providers.<name>.apiKey`, then a preset with that provider name and a model ID from that service. |
-| An OpenCode Zen or Go key | `providers.opencodeZen.apiKey` or `providers.opencodeGo.apiKey`, then a preset with `provider: "opencode_zen"` or `provider: "opencode_go"`. |
-| A company proxy or regional endpoint | The matching provider block plus `apiBase` if the proxy gives you a URL. |
-| A local OpenAI-compatible server | A local provider block such as `ollama`, `vllm`, `lmStudio`, or `custom`, usually with `apiBase`. |
-| An OAuth-based account | Run the matching `nanobot provider login ...` command, then select that provider explicitly in a preset. |
-| No provider yet | Pick one outside nanobot based on account access, pricing, regional availability, privacy requirements, and the model IDs you need. Then come back with its key and model ID. |
-
-## Minimal Shape
-
-```json
-{
-  "providers": {
-    "openrouter": {
-      "apiKey": "sk-or-v1-xxx"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "openrouter",
-      "model": "anthropic/claude-opus-4.5",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-The provider config gives nanobot credentials and endpoint details. The model preset names the provider/model pair. The agent defaults choose which named preset to use for normal turns. Replace the example provider and model together; mixing an API key from one provider with a model ID from another is the most common first-run failure.
-
-## Provider, Model, API Key, and Base URL
-
-These fields answer different questions:
-
-| Field | Where it lives | Meaning |
-|---|---|---|
-| `provider` | `modelPresets.<name>.provider` | Which nanobot provider adapter should send the request. |
-| `model` | `modelPresets.<name>.model` | The model ID expected by that provider or gateway. |
-| `apiKey` | `providers.<provider>.apiKey` | Credential for that provider. Use `${ENV_VAR}` for secrets. |
-| `apiBase` | `providers.<provider>.apiBase` | HTTP base URL of the provider endpoint. |
-| `proxy` | `providers.<provider>.proxy` | Optional HTTP proxy for this provider only. Supported for OpenAI-compatible providers and OpenAI Codex. |
-
-You usually omit `apiBase` for hosted built-in providers such as OpenRouter, Anthropic direct, OpenAI direct, Groq, or Bedrock because nanobot knows their default endpoints. Set `apiBase` for `custom`, local OpenAI-compatible servers, provider proxies, regional endpoints, or subscription endpoints. Include the API version path when the endpoint requires it, for example `https://api.example.com/v1` or `http://localhost:11434/v1`.
-
-Use `proxy` when one provider must send HTTP traffic through a proxy without changing process-wide `HTTP_PROXY` / `HTTPS_PROXY`. This is supported for providers that use nanobot's OpenAI-compatible client, including `openai`, `custom`, named custom providers, OpenRouter-style gateways, local OpenAI-compatible servers, and similar registry entries. It is also supported for `openai_codex`, including Codex OAuth token exchange/refresh and Codex Responses API requests. Native provider backends such as `anthropic`, `bedrock`, `azure_openai`, and `github_copilot` reject `proxy`; use their endpoint-specific configuration instead.
-
-## Common Provider Patterns
-
-### OpenRouter Gateway
-
-Gateway-style setup for model IDs served through OpenRouter.
-
-```json
-{
-  "providers": {
-    "openrouter": {
-      "apiKey": "${OPENROUTER_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "openrouter",
-      "model": "anthropic/claude-opus-4.5",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Use the model ID exactly as OpenRouter lists it.
-
-### OpenCode Zen and Go
-
-OpenCode Zen and OpenCode Go are OpenCode-managed gateways for coding-agent models.
-They share `OPENCODE_API_KEY`, but use separate provider config keys and default base
-URLs in nanobot.
-
-```json
-{
-  "providers": {
-    "opencodeZen": {
-      "apiKey": "${OPENCODE_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "opencode_zen",
-      "model": "opencode/deepseek-v4-pro",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-For OpenCode Go, switch the provider block and preset:
-
-```json
-{
-  "providers": {
-    "opencodeGo": {
-      "apiKey": "${OPENCODE_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "opencode_go",
-      "model": "opencode-go/deepseek-v4-flash",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    }
-  }
-}
-```
-
-OpenCode documents model IDs with `opencode/<model-id>` for Zen and
-`opencode-go/<model-id>` for Go. nanobot accepts those prefixes and strips them
-before sending the request to OpenCode. Use model IDs that OpenCode lists under
-the `chat/completions` endpoint; models listed only under `responses`,
-`messages`, or provider-specific endpoints are not handled by this
-OpenAI-compatible provider path.
-
-### Anthropic Direct
-
-```json
-{
-  "providers": {
-    "anthropic": {
-      "apiKey": "${ANTHROPIC_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "anthropic",
-      "model": "claude-opus-4-5",
-      "maxTokens": 8192,
-      "contextWindowTokens": 200000
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Anthropic direct uses the native Anthropic provider. Do not use an OpenRouter model ID unless the provider is OpenRouter.
-
-If you use an Anthropic-compatible proxy, keep the provider as `anthropic` and override `apiBase`:
-
-```json
-{
-  "providers": {
-    "anthropic": {
-      "apiKey": "${ANTHROPIC_API_KEY}",
-      "apiBase": "https://anthropic-proxy.example.com"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "anthropic",
-      "model": "claude-sonnet-4-5"
-    }
-  }
-}
-```
-
-Arbitrary custom provider names are OpenAI-compatible only; they do not use the Anthropic Messages API request format.
-
-### OpenAI Direct
-
-```json
-{
-  "providers": {
-    "openai": {
-      "apiKey": "${OPENAI_API_KEY}"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "openai",
-      "model": "gpt-5",
-      "maxTokens": 8192,
-      "contextWindowTokens": 128000
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-`providers.openai.apiType` may be set when you need to force a specific OpenAI API surface. Other providers reject `apiType`; leave it unset outside `providers.openai`. Replace the model with a model ID available to your OpenAI account.
-
-### Custom OpenAI-Compatible Endpoint
-
-The `custom` provider fits one OpenAI-compatible endpoint that is not represented by a named provider.
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "${CUSTOM_API_KEY}",
-      "apiBase": "https://example.com/v1"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "custom",
-      "model": "provider-model-name",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-`custom` does not infer a default base URL. Set `apiBase`.
-
-If you have more than one custom OpenAI-compatible endpoint, give each endpoint its own provider key under `providers` and use that same key in the model preset. The key can be a name that makes sense in your environment, such as `companyProxy`, `tenant-a`, or `dev-local`.
-
-```json
-{
-  "providers": {
-    "companyProxy": {
-      "apiKey": "${COMPANY_PROXY_API_KEY}",
-      "apiBase": "https://llm-proxy.example.com/v1"
-    },
-    "tenant-a": {
-      "apiBase": "https://tenant-a.example.com/v1"
-    }
-  },
-  "modelPresets": {
-    "company": {
-      "provider": "companyProxy",
-      "model": "gpt-4o-mini",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    },
-    "tenantA": {
-      "provider": "tenant-a",
-      "model": "served-model-name",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "company"
-    }
-  }
-}
-```
-
-Custom provider keys are treated as direct OpenAI-compatible providers. `apiBase` is required because nanobot cannot know the endpoint URL. `apiKey` is optional for local servers or private proxies that do not require one. Choose a name that does not conflict with a built-in provider name or alias, such as `openai`, `openai-codex`, `github-copilot`, or `lm-studio`. Do not set `apiType` on custom provider keys; `apiType` is only for `providers.openai`.
-
-If your custom endpoint documents a nonstandard thinking toggle, set `providers.<name>.thinkingStyle` to `thinking_type`, `enable_thinking`, or `reasoning_split`; nanobot then maps `reasoningEffort` onto that provider-specific request body. Leave it unset for ordinary OpenAI-compatible endpoints.
-
-This named custom provider path is not for Anthropic-compatible endpoints. For Anthropic-compatible proxies, use `providers.anthropic.apiBase` and set the preset provider to `anthropic`.
-
-### Ollama
-
-Start Ollama separately, then point nanobot at the OpenAI-compatible endpoint.
-
-```json
-{
-  "providers": {
-    "ollama": {
-      "apiBase": "http://localhost:11434/v1"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "ollama",
-      "model": "llama3.2",
-      "maxTokens": 4096,
-      "contextWindowTokens": 32768
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Most Ollama setups do not require an API key.
-
-### vLLM or Other Local OpenAI-Compatible Server
-
-```json
-{
-  "providers": {
-    "vllm": {
-      "apiBase": "http://127.0.0.1:8000/v1",
-      "apiKey": "EMPTY"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "vllm",
-      "model": "served-model-name",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Some OpenAI-compatible local servers require any non-empty API key even when they do not validate it.
-
-### LM Studio
-
-```json
-{
-  "providers": {
-    "lmStudio": {
-      "apiBase": "http://localhost:1234/v1"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "lm_studio",
-      "model": "local-model",
-      "maxTokens": 4096,
-      "contextWindowTokens": 32768
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-Config keys may be camelCase or snake_case. Provider names in model presets should use the registry name, such as `lm_studio`.
-
-### AWS Bedrock
-
-Bedrock can use the AWS credential chain, profile, region, or Bedrock bearer token depending on your AWS setup.
-
-```json
-{
-  "providers": {
-    "bedrock": {
-      "region": "us-east-1",
-      "profile": "default"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "provider": "bedrock",
-      "model": "bedrock/anthropic.claude-sonnet-4-5-20250929-v1:0",
-      "maxTokens": 8192,
-      "contextWindowTokens": 200000
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-See [`configuration.md#providers`](./configuration.md#providers) for Bedrock-specific notes.
-
-### OAuth Providers
-
-Some providers do not use API keys in `config.json`.
-
-```bash
-nanobot provider login openai-codex
-nanobot provider login github-copilot
-```
-
-Then explicitly select the provider and model in a preset. OAuth providers are not valid automatic fallbacks.
-
-For OpenAI Codex, add `providers.openai_codex.proxy` only when Codex OAuth/token refresh or Codex API requests must use a proxy:
-
-```json
-{
-  "providers": {
-    "openai_codex": {
-      "proxy": "http://127.0.0.1:7890"
-    }
-  },
-  "modelPresets": {
-    "codex": {
-      "provider": "openai_codex",
-      "model": "gpt-5.1-codex",
-      "reasoningEffort": "high"
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "codex"
-    }
-  }
-}
-```
-
-If you run the login command on a remote/headless machine and open the authorization URL in a local browser, paste the final `http://localhost:1455/auth/callback?...` redirect URL back into the terminal when prompted. See [`configuration.md#providers`](./configuration.md#providers) for the full OAuth provider notes.
-
-## Provider Resolution
-
-The recommended path is a named preset selected by `agents.defaults.modelPreset`. The effective model parameters come from:
-
-1. the named `modelPresets` entry referenced by `agents.defaults.modelPreset`;
-2. otherwise the implicit `default` preset built from `agents.defaults.model`, `provider`, `maxTokens`, `contextWindowTokens`, `temperature`, and related fields.
-
-Provider selection follows this practical rule:
-
-- Explicit `provider` in the active preset or implicit default config wins.
-- `provider: "auto"` tries model-name keywords, configured keys, local base URLs, and gateway providers.
-- Gateway providers such as OpenRouter and AiHubMix can route many model families, so the model name must be valid for that gateway.
-- Local providers should normally be explicit because generic local model names such as `llama3.2` do not always contain provider keywords.
-
-### Model Name Prefixes
-
-`family/model-name` does not always select provider `family`. Prefix-based provider inference only runs when the active provider is `"auto"`.
-
-- Explicit provider wins: `provider: "openrouter"` with `model: "anthropic/claude-sonnet-4.5"` calls OpenRouter, not Anthropic.
-- With `provider: "auto"`, a prefix matching a configured built-in or named custom provider can select that provider. Named custom prefixes are stripped before request, so `companyProxy/gpt-4o-mini` is sent upstream as `gpt-4o-mini`.
-- With an explicit named custom provider, the model is sent as written; `provider: "companyProxy"` with `model: "openai/gpt-4o-mini"` sends `openai/gpt-4o-mini` to `companyProxy`.
-
-Pin `provider` in presets when using gateway catalog IDs such as `anthropic/claude-sonnet-4.5`.
-
-## Model Presets
-
-Model presets are the recommended model configuration surface. Use them when you want named model choices, runtime `/model` switching, or reusable fallback targets.
-
-```json
-{
-  "modelPresets": {
-    "fast": {
-      "label": "Fast",
-      "provider": "openrouter",
-      "model": "anthropic/claude-sonnet-4.5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    },
-    "deep": {
-      "label": "Deep",
-      "provider": "anthropic",
-      "model": "claude-opus-4-5",

-```
-
-The preset name `default` is reserved for the implicit `agents.defaults` settings. Do not define `modelPresets.default`; use `/model default` to return to the direct `agents.defaults.*` fields in older configs.
-
-## Fallback Models
-
-Fallbacks are useful for transient provider failures, rate limits, or model availability issues. Keep fallbacks compatible with the task size and tool use. Prefer fallback presets so each candidate has a name and a complete provider, model, generation, and context-window configuration.
-
-```json
-{
-  "modelPresets": {
-    "fast": {
-      "label": "Fast",
-      "provider": "openrouter",
-      "model": "anthropic/claude-sonnet-4.5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    },
-    "deep": {
-      "label": "Deep",
-      "provider": "anthropic",
-      "model": "claude-opus-4-5",
-      "maxTokens": 8192,
-      "contextWindowTokens": 200000,
-      "temperature": 0.1
-    },
-    "localSmall": {
-      "label": "Local Small",
-      "provider": "ollama",
-      "model": "llama3.2",
-      "maxTokens": 4096,
-      "contextWindowTokens": 32768,
-      "temperature": 0.2
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "fast",
-      "fallbackModels": ["deep", "localSmall"]
-    }
-  }
-}
-```
-
-String entries in `fallbackModels` are preset names, not raw model names. nanobot tries them in order after the active preset. Each fallback preset uses its own `provider`, `model`, `maxTokens`, `contextWindowTokens`, `temperature`, and optional `reasoningEffort`.
-
-Use inline fallback objects only when a model is not worth naming as a preset:
-
-```json
-{
-  "modelPresets": {
-    "fast": {
-      "provider": "openrouter",
-      "model": "anthropic/claude-sonnet-4.5",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "fast",
-      "fallbackModels": [
-        {
-          "provider": "deepseek",
-          "model": "deepseek-v4-pro",
-          "maxTokens": 4096,
-          "contextWindowTokens": 262144
-        }
-      ]
-    }
-  }
-}
-```
-
-`fallbackModels` belongs under `agents.defaults`, not inside each preset. If fallback candidates use smaller context windows, nanobot builds context using the smallest window in the active chain so every candidate can receive the same prompt. See [`configuration.md#model-fallbacks`](./configuration.md#model-fallbacks) for failure conditions.
-
-## Quick Checks
-
-Run these before debugging a chat app:
-
-```bash
-nanobot status
-nanobot agent -m "Hello!"
-```
-
-If `nanobot agent -m "Hello!"` fails:
-
-| Symptom | Likely cause |
-|---|---|
-| 401, unauthorized, invalid API key | Key is missing, expired, copied with whitespace, or stored under the wrong provider |
-| model not found | Model ID does not exist for the selected provider or gateway |
-| connection refused | Local provider server is not running or `apiBase` points to the wrong port |
-| provider not found | The active preset uses a misspelled provider; use registry names such as `openrouter`, `anthropic`, `ollama`, `vllm`, `lm_studio` |
-| works in CLI but not chat app | Provider is fine; debug gateway/channel setup in [`chat-apps.md`](./chat-apps.md) or [`troubleshooting.md`](./troubleshooting.md) |

-

-      -> memory
-```
-
-## Before You Start
-
-Install and configure nanobot first. If you have not done that yet, follow the
-[Quick Start](quick-start.md) and complete the setup wizard. For SDK-only Python
-environments, install the package with:
-
-```bash
-python -m pip install nanobot-ai
-```
-
-`Nanobot.from_config()` reuses your normal `~/.nanobot/config.json` and
-`~/.nanobot/workspace/`. Provider, model, tools, memory, and session behavior
-match the CLI unless you override them. For the difference between config and
-workspace, see [Concepts: Config vs Workspace](concepts.md#config-vs-workspace).
-
-Before writing SDK code, run the same first-run checks from the main
-[Install and Quick Start](quick-start.md):
-
-```bash
-nanobot status
-```
-
-`nanobot status` should show the config path, workspace path, active model or
-preset, and provider summary. Then send one real message:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-A normal assistant reply means install, config, provider/model selection, and
-workspace access are all usable. Once that works, the SDK should see the same
-runtime.

-`await bot.aclose()` in a `finally` block.
-
-The SDK is async-first because agent runs may stream tokens, execute tools, and
-wait on external services. In a normal Python script, wrap your async function
-with `asyncio.run(...)` as shown above. In a notebook or another async app, call
-`await bot.run(...)` directly from your existing event loop.
-
-### Inspect What Happened
-
-`bot.run(...)` returns a `RunResult`, not just a string:
-
-```python
-result = await bot.run("Review this repository")
-
-print(result.content)     # final answer
-print(result.tools_used)  # tools the agent used
-print(result.usage)       # token usage when available
-print(result.stop_reason) # why the run stopped
-```
-
-### Continue A Conversation
-
-Use a `session_key` when you want history to carry across turns. Different
-session keys are isolated from each other:
-
-```python
-await bot.run("My name is Alice.", session_key="user:alice")
-result = await bot.run("What is my name?", session_key="user:alice")
-
-print(result.content)
-```
-
-This is the SDK equivalent of giving each user, task, eval case, or workflow
-its own conversation thread.
-
-### Stream A Long Answer
-
-For live output, use `bot.stream(...)`:
-
-```python
-from nanobot import STREAM_EVENT_TEXT_DELTA
-
-async for event in bot.stream("Write a migration plan"):
-    if event.type == STREAM_EVENT_TEXT_DELTA:
-        print(event.delta, end="", flush=True)

-
-Streaming returns structured events, so you can also observe tool calls,
-reasoning chunks, completion, and failures.

-
-[tool] list_dir
-Here are the top-level files I found...
-
-stop_reason: completed
-tools_used: ['list_dir']
-usage: {'prompt_tokens': ..., 'completion_tokens': ..., 'total_tokens': ...}

-stable `session_key`, stream events, keep the final `RunResult`, and let

-## Core Concepts
-
-| Concept | Meaning |
-|---------|---------|
-| `Nanobot` | The SDK object that owns one configured agent runtime. |
-| Run | One call to `bot.run(...)`, `bot.run_streamed(...)`, or `bot.stream(...)`. |
-| `session_key` | The conversation history key. Reuse it to continue a thread; change it to isolate a thread. |
-| Workspace | The local directory where file tools and shell tools operate. |
-| Tools | Capabilities the agent may call, such as file access, shell, web, or custom tools from your config. |
-| Memory | Long-term memory files managed by nanobot. |
-| Stream event | A typed event such as `text.delta`, `tool.started`, or `run.completed`. |
-| Model override | A temporary model or model preset used for one SDK instance or one run. |
-
-For most users, the mental model is:
-
-1. Create a `Nanobot` from config.
-2. Pick a `session_key`.
-3. Call `run` or `stream`.
-4. Read `RunResult` or stream events.
-5. Use session/memory/runtime helpers only when you need more control.
-
-## SDK Or OpenAI-Compatible API?
-
-nanobot has two programming surfaces:
-
-| Use | Choose | Why |
-|-----|--------|-----|
-| Python code running in the same process as nanobot | Python SDK | Direct access to `RunResult`, sessions, memory, runtime helpers, hooks, and stream events. |
-| Existing OpenAI-compatible clients, another language, or a separate process | [OpenAI-Compatible API](openai-api.md) | HTTP `/v1/chat/completions` compatibility with familiar client libraries. |
-
-The Python SDK is best when you are writing evals, notebooks, benchmark
-runners, product backends, local scripts, or integrations that should control
-nanobot directly.
-
-The OpenAI-compatible API is best when you already have an HTTP client, want
-process isolation, or need to call nanobot from a non-Python service.
 
 ## Common Patterns
 
 ### Use a specific config or workspace
 
-Set the workspace when your agent should work inside a specific project:
-
 ```python
 from nanobot import Nanobot
 
-async with Nanobot.from_config(workspace="/my/project") as bot:
+bot = Nanobot.from_config(
-    result = await bot.run("Explain the project structure")
+    config_path="~/.nanobot/config.json",
+    workspace="/my/project",
+)
 ```
 
-Use a custom config when you run multiple nanobot instances or test an isolated
-setup:
-
-```python
-async with Nanobot.from_config(
-    config_path="./bot-a/config.json",
-    workspace="./bot-a/workspace",
-) as bot:
-    result = await bot.run("Hello from bot A")
-```
-
-The config controls what nanobot may use. The workspace is where nanobot keeps
-state for that instance. See [multiple-instances.md](multiple-instances.md) for
-multi-instance CLI and gateway examples.
-
-### Choose a default or per-run model
-
-Set the SDK instance default model when you create the bot:
-
-```python
-bot = Nanobot.from_config(model="openai/gpt-4.1")
-```
-
-Override the model for one run without changing the instance default:
-
-```python
-result = await bot.run("Summarize this file", model="openai/gpt-4.1-mini")
-```
-
-Model presets from `config.json` work the same way:
-
-```python
-bot = Nanobot.from_config(model_preset="fast")
-
-result = await bot.run("Think deeply about this bug", model_preset="reasoning")
-```
-
-`model` and `model_preset` are mutually exclusive.
-
-For first setup, prefer named presets in `config.json`. Mixing an API key from
-one provider with a model ID from another is the most common first-run failure.
-For the exact difference between `provider`, `model`, `apiKey`, and `apiBase`,
-see [Providers: Provider, Model, API Key, and Base URL](providers.md#provider-model-api-key-and-base-url).
-If a run fails before the SDK does anything interesting, confirm the same
-provider and model work with `nanobot agent -m "Hello!"` first.
-
 ### Isolate conversations with `session_key`
 
 Different session keys keep independent conversation history:
@@ -306,131 +43,9 @@ await bot.run("hi", session_key="user-alice")
 await bot.run("hi", session_key="task-42")
 ```
 
-Use stable keys in product code:
-
-```python
-session_key = f"user:{user_id}"
-result = await bot.run(user_message, session_key=session_key)
-```
-
-Avoid using the default `"sdk:default"` for multiple users or unrelated
-workflows. It is convenient for local experiments, but stable product code
-should choose explicit keys such as `user:<id>`, `project:<id>`, or
-`eval:<case-id>`.
-
-### Handle failures
-
-For a normal non-streamed run, catch exceptions around `bot.run(...)` and inspect
-`RunResult.error` when the runtime returns a structured failure:
-
-```python
-try:
-    result = await bot.run("Review this repo", session_key="project:demo")
-except Exception as exc:
-    print(f"SDK call failed before a result was returned: {exc}")
-else:
-    if result.error:
-        print(f"Agent run failed: {result.error}")
-    else:
-        print(result.content)
-```
-
-For streamed runs, either consume the stream to completion or close it:
-
-```python
-run = await bot.run_streamed("Write a long answer", session_key="task:123")
-try:
-    async for event in run.stream_events():
-        ...
-finally:
-    if not run.done:
-        await run.aclose()
-```
-
-Use `await run.cancel()` when the user presses a stop button or leaves the page
-before the stream finishes.
-
-### Stream long-running output
-
-Use `bot.stream()` when you want Cursor/OpenAI-style live events instead of
-waiting for the final `RunResult`:
-
-```python
-from nanobot import (
-    STREAM_EVENT_RUN_COMPLETED,
-    STREAM_EVENT_TEXT_DELTA,
-    STREAM_EVENT_TOOL_STARTED,
-)
-
-async for event in bot.stream("Review this repository"):
-    if event.type == STREAM_EVENT_TEXT_DELTA:
-        print(event.delta, end="", flush=True)
-    elif event.type == STREAM_EVENT_TOOL_STARTED:
-        print(f"\nusing {event.name}")
-    elif event.type == STREAM_EVENT_RUN_COMPLETED:
-        print("\nfinal:", event.result.content)
-```
-
-Use `run_streamed()` when you also want a handle you can wait on:
-
-```python
-from nanobot import STREAM_EVENT_TEXT_DELTA
-
-run = await bot.run_streamed("Write a detailed migration plan")
-
-async for event in run.stream_events():
-    if event.type == STREAM_EVENT_TEXT_DELTA:
-        print(event.delta, end="", flush=True)
-
-result = await run.wait()
-```
-
-Always either consume the stream, call `await run.wait()` / `await run.text()`,
-or close it with `await run.cancel()` / `await run.aclose()`. Exiting
-`stream_events()` or `bot.stream()` early cancels the underlying run so a
-half-consumed stream cannot leave a background task stuck behind backpressure.
-
-### Import an existing transcript
-
-This is useful for evals, benchmark runners, migrations, and tests.
-
-Use `bot.sessions.ingest()` when you already have a transcript and want it to
-become nanobot session history. Ingesting a transcript does not call the model,
-execute tools, update memory, or compact automatically.
-
-```python
-await bot.sessions.ingest(
-    "eval:case-1",
-    [
-        {
-            "role": "user",

-
-| Constant | Value |
-|----------|-------|
-| `STREAM_EVENT_RUN_STARTED` | `run.started` |
-| `STREAM_EVENT_TEXT_DELTA` | `text.delta` |
-| `STREAM_EVENT_TEXT_COMPLETED` | `text.completed` |

 # Install and Quick Start
 
-This page gets one local nanobot reply working. After that, you can add the WebUI, chat apps, local models, web search, MCP, deployment, or custom plugins.
+## Install
-
-If you have never used a terminal or edited a config file before, use [`start-without-technical-background.md`](./start-without-technical-background.md) first. This page assumes you are comfortable pasting commands and editing JSON snippets.
-
-## Before You Start
-
-You need:
-
-- Python 3.11 or newer.
-- One LLM provider, company endpoint, subscription endpoint, or local model server you can call. The examples below use a generic OpenAI-compatible `custom` provider so the compact path does not recommend one hosted service; any supported provider works when the key, provider name, and model ID match.
-- Git only if you install from source.
-- Node.js or Bun only if you are developing the WebUI itself.
 
 > [!IMPORTANT]
-> Repository docs may describe features that are available first in source. Install from PyPI or `uv` for the stable day-to-day release; install from source when you want the newest repository behavior or plan to contribute.
+> This README may describe features that are available first in the latest source code.
+> If you want the newest features and experiments, install from source.
+> If you want the most stable day-to-day experience, install from PyPI or with `uv`.
 
-## 1. Install
+**Install from source** (latest features, experimental changes may land here first; recommended for development)
-
-Pick one install method.
-
-**One-command setup:**
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh
-```
-
-On Windows PowerShell:
-
-```powershell
-irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
-```
-
-The default command installs or upgrades `nanobot-ai` from PyPI, then starts `nanobot onboard --wizard`. It avoids system-wide pip installs by using an active virtual environment, `uv`, `pipx`, or a managed venv under `~/.nanobot/venv`. If Quick Start finishes and you enabled the WebSocket channel, go straight to [Open the WebUI](#5-open-the-webui).
-
-To preview the plan without changing your environment, pass `--dry-run`; combine it with `--dev` when you want to preview the main-branch install.
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dry-run
-```
-
-```powershell
-& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dry-run
-```
-
-To install the current `main` branch instead, pass `--dev`:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dev
-```
-
-```powershell
-& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dev
-```
-
-If `curl` or `irm` is unavailable, or GitHub raw downloads are blocked on your network, use one of the manual install methods below.
-
-If you prefer to inspect the script first, open [`../scripts/install.sh`](../scripts/install.sh) or [`../scripts/install.ps1`](../scripts/install.ps1).
-
-**Stable release with `uv`:**
-
-```bash
-uv tool install nanobot-ai
-nanobot --version
-```
-
-**Stable release with pip:**
-
-```bash
-python -m pip install nanobot-ai
-nanobot --version
-```
-
-Use pip only inside an environment you control. If pip reports `externally-managed-environment` on macOS or Linux, use the one-command installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or create a virtual environment first.
-
-**Latest source checkout:**
 
 ```bash
 git clone https://github.com/HKUDS/nanobot.git
 cd nanobot
-python -m pip install -e .
+pip install -e .
+```
+
+**Install with [uv](https://github.com/astral-sh/uv)** (stable release, fast)
+
+```bash
+uv tool install nanobot-ai
+```
+
+**Install from PyPI** (stable release)
+
+```bash
+pip install nanobot-ai
+```
+
+### Update to latest version
+
+**PyPI / pip**
+
+```bash
+pip install -U nanobot-ai
 nanobot --version
 ```
 
-If your shell cannot find `nanobot` after a pip install, run the module form:
+**uv**
-
-```bash
-python -m nanobot --version
-python -m nanobot onboard
-```
-
-On Windows, `~` in the docs means your user profile directory, for example `C:\Users\you`.
-
-The docs use `python` in commands. If your system exposes Python 3.11+ as `python3` or `py`, use that command in the same place, for example `python3 -m pip install nanobot-ai` or `py -m nanobot --version`.
-
-## 2. Initialize
-
-Skip this section if the one-command setup already started the wizard and Quick Start finished there.
-
-```bash
-nanobot onboard
-```
-
-Use the wizard if you prefer prompts instead of editing JSON by hand:
-
-```bash
-nanobot onboard --wizard
-```
-
-Initialization creates:
-
-| Path | What it is |
-|------|------------|
-| `~/.nanobot/config.json` | Main settings file for providers, models, channels, tools, gateway, and API |
-| `~/.nanobot/workspace/` | Agent workspace for memory, sessions, heartbeat tasks, skills, and artifacts |
-
-If you already have a config, `nanobot onboard` can refresh missing default fields without overwriting your existing values.
-
-## 3. Configure a Provider
-
-Skip this section if you already configured provider and model settings in the wizard.
-
-Open `~/.nanobot/config.json`. Add or merge these blocks into the file created by `nanobot onboard`; do not replace the whole file unless you want to reset the config.
-
-**API key:**
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "your-api-key",
-      "apiBase": "https://api.example.com/v1"
-    }
-  }
-}
-```
-
-**Model preset:**
-
-```json
-{
-  "modelPresets": {
-    "primary": {
-      "label": "Primary",
-      "provider": "custom",
-      "model": "model-id-from-your-provider",
-      "maxTokens": 8192,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-The provider and model inside a preset must match. The snippet above is only an example. For another provider, replace these values together:
-
-| Replace | Where |
-|---|---|
-| Provider config key, such as `custom` | `providers.<provider>` |
-| API key or environment variable | `providers.<provider>.apiKey` |
-| Preset provider name | `modelPresets.primary.provider` |
-| Model ID | `modelPresets.primary.model` |
-| Endpoint URL, only when needed | `providers.<provider>.apiBase` |
-
-Direct `agents.defaults.provider` and `agents.defaults.model` still work for existing configs, but named presets are the recommended path because they also power `/model` switching and fallback chains. For provider-specific examples across direct, gateway, OAuth, cloud, and local setups, see [`providers.md`](./providers.md).
-
-**What about `apiBase` / base URL?**
-
-`apiBase` is the HTTP base URL of the provider endpoint, not the model name. Most hosted providers in nanobot already know their default endpoint, so you usually only set `apiKey` and a model preset. Set `apiBase` when you are using:
-
-- `custom` for a third-party or self-hosted OpenAI-compatible API;
-- a local OpenAI-compatible server such as Ollama, vLLM, or LM Studio;
-- a provider-specific alternate endpoint, regional endpoint, proxy, or subscription endpoint.
-
-Examples:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "${CUSTOM_API_KEY}",
-      "apiBase": "https://api.example.com/v1"
-    }
-  }
-}
-```
-
-```json
-{
-  "providers": {
-    "ollama": {
-      "apiBase": "http://localhost:11434/v1"
-    }
-  }
-}
-```
-
-If the provider's docs say the endpoint is `/v1`, include `/v1` in `apiBase`. The model ID still belongs in the active `modelPresets` entry.
-
-If you prefer not to store secrets in `config.json`, reference an environment variable and set it before starting nanobot:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "${PROVIDER_API_KEY}",
-      "apiBase": "https://api.example.com/v1"
-    }
-  }
-}
-```
-
-## 4. Check the Setup
-
-```bash
-nanobot status
-```
-
-This should show the config path, workspace path, active model or preset, and provider summary. It does not send a message to the model, so use it as a quick config check before the first real request.
-
-Read it like this:
-
-| Status line | What you want |
-|---|---|
-| `Config` | A check mark. |
-| `Workspace` | A check mark. |
-| `Model` | The model or preset you expect. |
-| Provider list | Most providers can say `not set`; the provider used by the active preset should show a check mark, OAuth status, or local URL. |
-
-## 5. Open the WebUI
-
-If Quick Start enabled the WebSocket channel, start the gateway:
-
-```bash
-nanobot gateway
-```
-
-Leave that terminal open, then open `http://127.0.0.1:8765` in your browser. Enter the WebUI password you set in the wizard, then send your first message there.
-
-## 6. Test One CLI Message
-
-Use this path if you skipped Quick Start, declined the WebSocket channel, or want a terminal-only check.
-
-Run a one-shot CLI message:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-A successful first run proves that:
-
-- the `nanobot` command is installed;
-- `~/.nanobot/config.json` can be loaded;
-- the selected provider and model can answer;
-- the default workspace can be created and used.
-
-The reply text itself will vary. Any normal assistant answer means the install, config, provider, model, and workspace path are all usable.
-
-If that works, start an interactive CLI chat:
-
-```bash
-nanobot agent
-```
-
-After the interactive session can answer normally, nanobot can help with its own next setup step. Ask it to read the relevant docs, inspect your current `~/.nanobot/config.json`, and make one concrete change such as enabling WebUI, adding a provider preset, or configuring one chat channel. When nanobot says the config is updated, run `/restart` in the chat or restart the nanobot process manually so long-running processes reload `config.json`.
-
-Example prompt:
-
-```text
-Read docs/quick-start.md, docs/providers.md, and docs/configuration.md in this checkout.
-Then update ~/.nanobot/config.json to add a model preset named "primary" for my provider.
-Tell me exactly what changed and whether I need to run /restart.
-```
-
-Exit interactive mode with `exit`, `quit`, `/exit`, `/quit`, `:q`, or `Ctrl+D`.
-
-## 7. Choose Your Next Step
-
-| Want to... | Go to |
-|---|---|
-| Understand config, workspace, gateway, channels, memory, and tools | [`concepts.md`](./concepts.md) |
-| Copy another provider or local model setup | [`provider-cookbook.md`](./provider-cookbook.md) |
-| Understand provider/model matching | [`providers.md`](./providers.md) |
-| Open the bundled browser UI | [`webui.md`](./webui.md) |
-| Connect Telegram, Discord, WeChat, Slack, Email, or another chat app | [`chat-apps.md`](./chat-apps.md) |
-| Configure web search, MCP, security, memory, gateway, or runtime settings | [`configuration.md`](./configuration.md) |
-| Run with Docker, systemd, or LaunchAgent | [`deployment.md`](./deployment.md) |
-| Debug a failure | [`troubleshooting.md`](./troubleshooting.md) |
-
-## Updating
-
-**pip:**
-
-```bash
-python -m pip install -U nanobot-ai
-nanobot --version
-```
-
-If pip reports `externally-managed-environment`, upgrade with the same isolated method you used to install nanobot, such as `uv tool upgrade nanobot-ai`, `pipx upgrade nanobot-ai`, or the managed venv created by the one-command installer.
-
-**uv:**
 
 ```bash
 uv tool upgrade nanobot-ai
 nanobot --version
 ```
 
-**pipx:**
+**Using WhatsApp?** Rebuild the local bridge after upgrading:
 
 ```bash
-pipx upgrade nanobot-ai
+rm -rf ~/.nanobot/bridge
-nanobot --version
+nanobot channels login whatsapp
 ```
 
-**Source checkout:**
+## Quick Start
+
+> [!TIP]
+> Set your API key in `~/.nanobot/config.json`.
+> Get API keys: [OpenRouter](https://openrouter.ai/keys) (Global)
+>
+> For other LLM providers, please see [`configuration.md`](./configuration.md).
+>
+> For web search capability setup, please see the web-search section in [`configuration.md`](./configuration.md#web-search).
+
+**1. Initialize**
 
 ```bash
-git pull
+nanobot onboard
-python -m pip install -e .
-nanobot --version
 ```
 
-If you use WhatsApp from a source checkout, keep the optional dependencies installed:
+Use `nanobot onboard --wizard` if you want the interactive setup wizard.
+
+**2. Configure** (`~/.nanobot/config.json`)
+
+Configure these **two parts** in your config (other options have defaults).
+
+*Set your API key* (e.g. OpenRouter, recommended for global users):
+```json
+{
+  "providers": {
+    "openrouter": {
+      "apiKey": "sk-or-v1-xxx"
+    }
+  }
+}
+```
+
+*Set your model* (optionally pin a provider — defaults to auto-detection):
+```json
+{
+  "agents": {
+    "defaults": {
+      "model": "anthropic/claude-opus-4-5",
+      "provider": "openrouter"
+    }
+  }
+}
+```
+
+**3. Chat**
 
 ```bash
-python -m pip install -e ".[whatsapp]"
+nanobot agent
 ```
 
-## First-Run Troubleshooting
+That's it! You have a working AI agent in 2 minutes.
-
-| Symptom | What to check |
-|---------|---------------|
-| `nanobot: command not found` | Use `python -m nanobot ...`, or add your Python scripts directory to `PATH`. |
-| `ModuleNotFoundError: nanobot` | Confirm you installed into the same Python environment that is running the command. |
-| JSON parse errors | Check commas and braces in `~/.nanobot/config.json`; examples above are partial snippets to merge. |
-| Authentication or 401 errors | Check that the API key is valid, copied without spaces, and placed under the provider you selected. |
-| Provider/model errors | Make sure the active preset uses the provider that owns your API key and that the model exists there. |
-| The CLI works but a chat app does not reply | First keep `nanobot gateway` running, then follow [`chat-apps.md`](./chat-apps.md). |
-| WebUI does not open | Enable the WebSocket channel and open port `8765`, not the gateway health port `18790`. |

-# Start Without Technical Background
-
-This page is for you if you have never used a terminal, edited a JSON file, or configured an AI model before.
-
-The goal is small: get one local nanobot reply in your browser. Do not connect Telegram, Discord, Docker, local models, or deployment yet. Those are easier after the first reply works.
-
-## What You Are Setting Up
-
-You only need these words for Quick Start:
-
-| Word | Plain meaning |
-|---|---|
-| Terminal | A text window where you paste commands and press Enter. |
-| Command | One line of text you run in the terminal. |
-| API key | A password-like token from an AI provider. Do not share it publicly. |
-| Config file | The settings file nanobot reads when it starts. |
-| Wizard | An interactive terminal menu that edits the config file for you. |
-| Browser UI | The local web page where you chat with nanobot. |
-
-## 1. Open a Terminal
-
-You will paste commands into a terminal. Copy only the command text inside each code block; do not copy the ``` marks.
-
-| System | How to open it |
-|---|---|
-| Windows | Press `Win`, type `PowerShell`, then open **Windows PowerShell**. |
-| macOS | Press `Command` + `Space`, type `Terminal`, then press `Enter`. |
-| Linux | Open your app launcher, search for `Terminal`, then open it. |
-
-When the terminal opens, click inside it, paste the command, and press `Enter`. If a command prints text and returns to a prompt, that is usually normal.
-
-## 2. Install Python
-
-Install Python 3.11 or newer from [python.org](https://www.python.org/downloads/).
-
-On Windows, enable **Add python.exe to PATH** during installation if the installer shows that option.
-
-In that terminal, check Python:
-
-```bash
-python --version
-```
-
-If Windows says `python` is not found, close and reopen PowerShell. If it still does not work, try:
-
-```bash
-py --version
-```
-
-If `py` works but `python` does not, replace `python` with `py` in the commands below.
-
-If macOS or Linux says `python` is not found, try:
-
-```bash
-python3 --version
-```
-
-If `python3` works but `python` does not, replace `python` with `python3` in the manual commands below. The one-command installer already checks both `python3` and `python`.
-
-## 3. Get a Provider API Key
-
-nanobot does not create AI accounts or API keys for you. Use an AI provider account, company endpoint, subscription endpoint, or local model server that you already control. If the provider has an OpenAI-compatible base URL in its docs, keep that nearby too.
-
-For the setup path:
-
-1. Open your provider's API key page.
-2. Create or copy an API key.
-3. Keep the key private.
-4. Keep the provider's base URL nearby if the provider docs show one.
-
-## 4. Install nanobot
-
-The easiest path is the one-command installer. It installs or upgrades nanobot, then starts the setup wizard. On macOS and Linux it avoids system-wide pip installs by using an active virtual environment, `uv`, `pipx`, or a managed venv under `~/.nanobot/venv`.
-
-**macOS / Linux**
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh
-```
-
-**Windows PowerShell**
-
-```powershell
-irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
-```
-
-These commands install the stable PyPI package. To preview what the installer would do without changing your environment, pass `--dry-run`:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dry-run
-```
-
-```powershell
-& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dry-run
-```
-
-Use the development installer only when a maintainer asks you to test the current `main` branch:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dev
-```
-
-```powershell
-& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dev
-```
-
-If the command says `curl` or `irm` is not found, or it cannot download from GitHub, use one of the manual install commands below.
-
-If `uv` is installed, use:
-
-```bash
-uv tool install nanobot-ai
-```
-
-If you prefer pip, use it only inside an environment you control:
-
-```bash
-python -m pip install nanobot-ai
-```
-
-If pip reports `externally-managed-environment` on macOS or Linux, go back to the one-command installer, use `uv tool install nanobot-ai`, use `pipx install nanobot-ai`, or create a virtual environment first.
-
-Then check that nanobot is installed:
-
-```bash
-nanobot --version
-```
-
-If the terminal cannot find `nanobot`, use the module form:
-
-```bash
-python -m nanobot --version
-```
-
-Use `python3 -m nanobot --version` or `py -m nanobot --version` if that is the Python command that worked in step 2.
-
-## 5. Run the Setup Wizard
-
-The one-command installer starts this for you after installation. If you installed manually, run:
-
-```bash
-nanobot onboard --wizard
-```
-
-If `nanobot` is not found, run:
-
-```bash
-python -m nanobot onboard --wizard
-```
-
-Use `python3 -m nanobot onboard --wizard` or `py -m nanobot onboard --wizard` if that is the Python command that worked in step 2.
-
-The wizard is a terminal menu. It is not a graphical app, but it lets you choose options instead of hand-editing every JSON field.
-
-You will see a menu like this:
-
-```text
-> What would you like to do?
-  [Q] Quick Start
-  [A] Advanced Settings
-  [X] Exit
-```
-
-Move through the wizard like this:
-
-| When you see | Do this |
-|---|---|
-| A menu | Use the arrow keys to highlight an option, then press `Enter`. |
-| The provider menu | Choose the company or service you want to use. |
-| An endpoint menu | Choose the standard API or subscription plan endpoint that matches your key. |
-| An API key field | Paste the key, then press `Enter`. |
-| A provider base URL field | Paste the provider base URL from its docs, then press `Enter`. |
-| The Model ID field | Paste a model name from your provider, then press `Enter`. |
-| A back option in Advanced Settings | Choose it to return to the previous menu. |
-
-For the first setup, choose `[Q] Quick Start`. It configures the recommended local browser UI and default AI settings for you. Use `Advanced Settings` later only if you need a chat app, a tool setup, or provider-specific fields.
-
-1. Choose `[Q] Quick Start`.
-2. Choose the provider you want to use.
-3. Choose the endpoint if the wizard asks, such as Standard API, Coding Plan, Token Plan, or Step Plan.
-4. Paste your API key if the wizard asks for one.
-5. Paste the provider base URL if the wizard asks for one.
-6. Paste a model ID that provider can run.
-7. Confirm that Quick Start should enable the WebSocket channel for the local WebUI.
-8. Set the WebUI password when prompted.
-9. Review the Quick Start summary. The wizard saves and exits when Quick Start finishes.
-
-The recommended path enables `channels.websocket` for the local WebUI, requires a WebUI password, and writes default AI settings. You do not need to choose a separate chat app for the first run.
-
-If you already know that you need custom headers, provider-specific request fields, a chat app, or tools, choose `Advanced Settings` instead. [`provider-cookbook.md`](./provider-cookbook.md) has copyable examples for several common provider setups. After you change advanced settings, a save option appears in the main menu. Choose `[S] Save and Exit`.
-
-The wizard creates or updates:
-
-| Path | Meaning |
-|---|---|
-| `~/.nanobot/config.json` | Settings file. |
-| `~/.nanobot/workspace/` | Working folder for memory, sessions, and generated files. |
-
-If Quick Start finished successfully, skip to [Open the WebUI](#7-open-the-webui). The next two sections are only for manual setup.
-
-## Manual Setup: How to Merge JSON Snippets
-
-Most docs examples are snippets, not whole files. Your `config.json` has one outer `{ ... }`. Add new top-level sections such as `providers`, `modelPresets`, `agents`, or `channels` inside that same outer object.
-
-Do not paste two separate JSON objects into one file:
-
-```text
-{
-  "providers": { "...": "..." }
-}
-{
-  "channels": { "...": "..." }
-}
-```
-
-Merge them into one object:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "your-api-key",
-      "apiBase": "https://api.example.com/v1"
-    }
-  },
-  "channels": {
-    "websocket": {
-      "enabled": true,
-      "tokenIssueSecret": "your-webui-password",
-      "websocketRequiresToken": true
-    }
-  }
-}
-```
-
-Notice the comma after the `providers` block. JSON needs commas between sibling sections, but not after the last section. If this feels hard, use `nanobot onboard --wizard` whenever possible.
-
-## 6. Manual Setup: Config Fallback
-
-Use this only if the wizard is unavailable or you prefer opening the file yourself.
-
-Run `nanobot onboard` first if `~/.nanobot/config.json` does not exist yet.
-
-Use one of these commands:
-
-**Windows PowerShell**
-
-```powershell
-notepad "$env:USERPROFILE\.nanobot\config.json"
-```
-
-**macOS**
-
-```bash
-open -e ~/.nanobot/config.json
-```
-
-**Linux**
-
-```bash
-xdg-open ~/.nanobot/config.json
-```
-
-If this is a brand-new install and you have not configured anything else yet, replace the file with this minimal config:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "your-api-key",
-      "apiBase": "https://api.example.com/v1"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "Primary",
-      "provider": "custom",
-      "model": "model-id-from-your-provider",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  },
-  "channels": {
-    "websocket": {
-      "enabled": true,
-      "tokenIssueSecret": "your-webui-password",
-      "websocketRequiresToken": true
-    }
-  }
-}
-```
-
-Replace `your-api-key`, `https://api.example.com/v1`, `model-id-from-your-provider`, and `your-webui-password` with your own values.
-
-For copyable provider-specific examples, use [`provider-cookbook.md`](./provider-cookbook.md).
-
-Save the file.
-
-## 7. Open the WebUI
-
-First check that nanobot can read the saved setup:
-
-```bash
-nanobot status
-```
-
-This should show the config file path, workspace path, and the active model or preset. If `nanobot` is not found, use `python -m nanobot status`, `python3 -m nanobot status`, or `py -m nanobot status`, matching the Python command that worked in step 2.
-
-It is normal for most providers to say `not set`. Only the provider you selected for the active preset needs to look configured.
-
-Start the local browser UI:
-
-```bash
-nanobot gateway
-```
-
-Leave that terminal open, then open `http://127.0.0.1:8765` in your browser. Enter the WebUI password you set in the wizard or the `tokenIssueSecret` value from your manual config.
-
-Send this first message in the browser:
-
-```text
-Hello!
-```
-
-If that works, nanobot is installed and can call the model. You should see a normal assistant reply in the browser. The exact words will differ, but it should look like this shape:
-
-```text
-Hello! How can I help you today?
-```
-
-If `nanobot` is not found, run:
-
-```bash
-python -m nanobot gateway
-```
-
-Use `python3 -m nanobot gateway` or `py -m nanobot gateway` if that is the Python command that worked in step 2.
-
-Once this works, nanobot can help with its own next setup step. In the browser UI, ask it to read these docs and update your current config for one specific goal, then run `/restart` when nanobot tells you the config is ready. For example, ask it to add one provider preset or configure one chat app.
-
-## 8. If Something Fails
-
-Do not change many things at once. Check the exact error:
-
-| Error or symptom | What it usually means |
-|---|---|
-| `JSON parse error` | The config file has a missing comma, extra comma, or mismatched brace. Copy the example again. |
-| `401`, `unauthorized`, or `invalid API key` | The API key is wrong, expired, has extra spaces, or was pasted under the wrong provider. |
-| `model not found` | Your account cannot use the default model. Return to `nanobot onboard --wizard`, choose `Advanced Settings`, then edit `Model Presets`. |
-| `nanobot: command not found` | The install worked in Python, but your shell cannot find the script. Use `python -m nanobot ...`, `python3 -m nanobot ...`, or `py -m nanobot ...`, matching the Python command that worked earlier. |
-| No response after editing config | Restart the command. Long-running processes read config when they start. |
-
-For a fuller diagnosis path, see [`troubleshooting.md`](./troubleshooting.md).
-
-## What Not to Configure Yet
-
-Skip these until the first local message works:
-
-- `apiBase`: hosted built-in providers often already have default endpoints. You only need `apiBase` for local models, proxies, custom OpenAI-compatible providers, or special regional/subscription endpoints.
-- chat apps: first prove the local browser UI can answer.
-- fallback models: useful later, but not needed for the first reply.
-- Langfuse: useful for observability, but not needed for first setup.
-
-## Next Steps
-
-After the first reply works, choose only one next goal. Keep the terminal that runs `nanobot gateway` open whenever you use the WebUI or a chat app.
-
-### Open the Browser UI Again
-
-Run:
-
-```bash
-nanobot gateway
-```
-
-Leave that terminal open, then open `http://127.0.0.1:8765` in your browser.
-
-To stop the WebUI later, return to the gateway terminal and press `Ctrl+C`.
-
-If `nanobot` is not found, run `python -m nanobot gateway`, `python3 -m nanobot gateway`, or `py -m nanobot gateway`, matching the Python command that worked earlier. More details are in [`webui.md`](./webui.md).
-
-### Connect a Chat App
-
-1. Read the section for one app in [`chat-apps.md`](./chat-apps.md).
-2. Add only that app's config snippet. Merge it into the existing file instead of replacing the whole file.
-3. Run:
-
-```bash
-nanobot channels status
-nanobot gateway
-```
-
-4. Leave the gateway terminal open, then send a message from the allowed account.
-
-Start with a private chat or a test server. Do not set `allowFrom` to `["*"]` unless you intentionally want anyone who can reach that channel to talk to the bot.
-
-### Change Models or Add Backups
-
-Use [`providers.md`](./providers.md) when a provider/model pair fails, and [`provider-cookbook.md`](./provider-cookbook.md) when you want copyable snippets. Keep model choices in `modelPresets`, then select the active one with `agents.defaults.modelPreset`.
-
-### Ask for Help
-
-When you ask for help, include:
-
-- your operating system;
-- the command you ran;
-- `nanobot --version`;
-- `nanobot status`;
-- whether the browser UI can answer `Hello!`;
-- the exact error text;
-- a config snippet with API keys and tokens removed.
-
-Never paste real API keys, bot tokens, OAuth tokens, or private chat IDs into a public issue or chat.
-
-If you find a docs mistake, outdated command, or confusing step, please open an issue: <https://github.com/HKUDS/nanobot/issues>.

-# Troubleshooting
-
-Use this page to isolate where a failure lives. Start with the smallest surface that proves the most: local CLI first, then gateway, then WebUI or chat apps.
-
-## Fast Diagnosis Order
-
-Run these in order:
-
-```bash
-nanobot --version
-nanobot status
-nanobot agent -m "Hello!"
-```
-
-Then, only if the CLI works:
-
-```bash
-nanobot gateway
-```
-
-This separates failures into layers:
-
-| Layer | What it proves |
-|---|---|
-| `nanobot --version` | Install and shell command discovery |
-| `nanobot status` | Config path, workspace path, active model, and provider summary |
-| `nanobot agent -m "Hello!"` | Config loading, provider/model access, workspace writes, and agent loop |
-| `nanobot gateway` | Channel startup, cron system jobs, heartbeat, WebUI/WebSocket, and health endpoint |
-
-If `nanobot agent -m "Hello!"` fails, fix that before debugging WebUI, Telegram, Discord, Docker, systemd, or any chat app.
-
-## How to Read `nanobot status`
-
-`nanobot status` does not call a model. It only checks whether nanobot can find the default config, default workspace, active model or preset, and provider setup summary.
-
-The output has this shape:
-
-```text
-nanobot Status
-
-Config: /path/to/config.json ✓
-Workspace: /path/to/workspace ✓
-Model: provider/model-name (preset: primary)
-Provider A: not set
-Provider B: ✓
-Local Provider: ✓ http://localhost:11434/v1
-OAuth Provider: ✓ (OAuth)
-```
-
-Read it like this:
-
-| Line | Good sign | What to do if it looks wrong |
-|---|---|---|
-| `Config` | It points to the config file you meant to use and shows `✓`. | Run `nanobot onboard`, or pass `--config` to `nanobot agent`, `gateway`, or `serve` when testing a non-default instance. |
-| `Workspace` | It points to the workspace you meant to use and shows `✓`. | Run `nanobot onboard`, create the folder, fix permissions, or pass `--workspace` on commands that support it. |
-| `Model` | It shows the active model or the preset name you expect. | Set `agents.defaults.modelPreset` to the intended preset, or check `/model` if you changed models during a chat session. |
-| Provider rows | The provider used by the active preset shows `✓`, an OAuth marker, or a local URL. | Configure only the active provider first. It is normal for unused providers to say `not set`. |
-
-If `nanobot status` looks right but `nanobot agent -m "Hello!"` fails, the install and config paths are probably fine. Continue with [Provider and Model Problems](#provider-and-model-problems).
-
-## Installation Problems
-
-Use the same Python command for install checks and module fallback. On macOS/Linux that may be `python3`; on Windows it may be `python` or `py`.
-
-| Symptom | Check |
-|---|---|
-| `python: command not found` | Try `python3 --version` on macOS/Linux or `py --version` on Windows. Then replace `python` in docs commands with the command that worked. |
-| `curl: command not found` | The macOS/Linux one-command installer could not download the script. Install curl, or use a manual isolated install such as `uv tool install nanobot-ai` or `pipx install nanobot-ai`. |
-| `irm` is not recognized | PowerShell could not run the download helper. Use manual install: `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or `py -m pip install nanobot-ai` inside an environment you control. |
-| Could not download `raw.githubusercontent.com` | Your network, proxy, or firewall blocked the installer script download. Use manual install from PyPI, or configure your proxy and rerun the command. |
-| `nanobot: command not found` | Use the module form, for example `python -m nanobot ...`, `python3 -m nanobot ...`, or `py -m nanobot ...`. Reinstall with the same Python command, or add that Python's scripts directory to `PATH`. |
-| `No module named nanobot` | You are running a different Python than the one used for installation. Run `python -m pip show nanobot-ai`, `python3 -m pip show nanobot-ai`, or `py -m pip show nanobot-ai`, matching the command that installed nanobot. |
-| `pip is not available` | When the installer uses a virtual environment, it tries `python -m ensurepip --upgrade`. If that fails, install pip for that Python, or use a Python installer/distribution that includes pip. |
-| `externally-managed-environment` | Your system Python blocks global pip installs. Use the one-command installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or create a virtual environment; do not add `--break-system-packages` for nanobot. |
-| Installer chose the wrong Python | Set `PYTHON` before running the installer, such as `curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | PYTHON=python3 sh` or `$env:PYTHON="py"` before the PowerShell command. |
-| Editable source install does not update | From the repo root, run `python -m pip install -e .` again with the Python command used for development, then check `python -m nanobot --version` or `nanobot --version`. |
-| WebUI build tools missing | They are only needed for WebUI development. Packaged installs already include the WebUI bundle. |
-
-## Config Problems
-
-Default config path:
-
-```text
-~/.nanobot/config.json
-```
-
-Default workspace path:
-
-```text
-~/.nanobot/workspace/
-```
-
-`nanobot status` reads the default config. Use explicit paths on commands that support them when debugging multiple instances:
-
-```bash
-nanobot agent --config ./bot-a/config.json --workspace ./bot-a/workspace -m "Hello"
-nanobot gateway --config ./bot-a/config.json --workspace ./bot-a/workspace
-```
-
-Common config mistakes:
-
-| Symptom | Check |
-|---|---|
-| JSON parse error | Validate commas, braces, and quotes. Most docs examples are partial snippets to merge. |
-| Unknown or missing provider | Use provider registry names such as `openrouter`, `anthropic`, `openai`, `ollama`, `vllm`, `lm_studio`, or define a custom OpenAI-compatible provider key under `providers` and reference that exact key from the active preset. |
-| snake_case vs camelCase confusion | Both are accepted, but docs use camelCase because nanobot writes config with aliases such as `apiKey`, `modelPresets`, `intervalS`. |
-| Environment variable error | `${VAR_NAME}` references are resolved at startup. Set the variable before running nanobot. |
-| Edited config but behavior did not change | Restart `nanobot gateway`; long-running processes read config at startup. |
-
-To refresh missing defaults without overwriting existing settings, run:
-
-```bash
-nanobot onboard
-```
-
-When prompted about overwriting the config, choose the option that keeps current values and merges missing defaults.
-
-## Provider and Model Problems
-
-First prove the provider in the CLI:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-Then compare your config against [`providers.md`](./providers.md).
-
-If you need a known-good snippet instead of diagnosis, use [`provider-cookbook.md`](./provider-cookbook.md).
-
-| Symptom | Likely cause |
-|---|---|
-| 401, unauthorized, invalid API key | Key is missing, expired, pasted with whitespace, or under the wrong provider key. |
-| Model not found | The model ID belongs to a different provider or gateway. |
-| Provider cannot be inferred | Pin `modelPresets.<name>.provider` in the active preset instead of using `"auto"`. For legacy direct configs, pin `agents.defaults.provider`. |
-| Local model connection refused | Ollama, vLLM, LM Studio, or another local server is not running, or `apiBase` points to the wrong port. |
-| Bedrock validation error | Check AWS region, credentials, model access, model ID, and whether the model supports Converse. |
-| OAuth provider fails | Run `nanobot provider login openai-codex` or `nanobot provider login github-copilot`, then select the provider explicitly. |
-
-## Langfuse Problems
-
-Langfuse tracing is optional and controlled by environment variables.
-
-| Symptom | Check |
-|---|---|
-| `LANGFUSE_SECRET_KEY is set but langfuse is not installed` | Install `langfuse` in the same Python environment that runs nanobot, then restart the process. |
-| No traces appear | Set `LANGFUSE_SECRET_KEY`, `LANGFUSE_PUBLIC_KEY`, and `LANGFUSE_BASE_URL` before starting nanobot. |
-| Wrong Langfuse project or region | Check that the key pair and `LANGFUSE_BASE_URL` come from the same Langfuse project/region. |
-| Only some providers trace | Langfuse tracing applies to OpenAI-compatible provider calls; native providers may not use that client path. |
-
-See [`configuration.md#langfuse-observability`](./configuration.md#langfuse-observability) for setup commands.
-
-## Gateway Problems
-
-`nanobot gateway` is required for WebUI, chat apps, heartbeat, Dream, and long-running channel connections.
-
-Default ports:
-
-| Surface | Default |
-|---|---|
-| Gateway health endpoint | `http://127.0.0.1:18790/health` |
-| WebUI/WebSocket channel | `http://127.0.0.1:8765` |
-| OpenAI-compatible API (`nanobot serve`) | `http://127.0.0.1:8900` |
-
-Common gateway checks:
-
-```bash
-nanobot gateway --verbose
-```
-
-| Symptom | Check |
-|---|---|
-| Port already in use | Change `gateway.port`, `channels.websocket.port`, or the `--port` CLI flag for the relevant command. |
-| WebUI opened on `18790` but shows nothing useful | Open `8765`; `18790` is the health endpoint. |
-| Config changes ignored | Restart the gateway. |
-| Heartbeat never runs | Keep the gateway running, add tasks under `<workspace>/HEARTBEAT.md` -> `## Active Tasks`, and make sure `gateway.heartbeat.enabled` is true. |
-| Cron jobs disappeared after switching workspaces | Cron jobs are workspace-scoped at `<workspace>/cron/jobs.json`; check you are using the intended workspace. |
-
-## WebUI Problems
-
-The packaged WebUI is served by the WebSocket channel.
-
-Minimal config:
-
-```json
-{
-  "channels": {
-    "websocket": {
-      "enabled": true
-    }
-  }
-}
-```
-
-Then run:
-
-```bash
-nanobot gateway
-```
-
-Open:
-
-```text
-http://127.0.0.1:8765
-```
-
-If accessing from another device, bind the WebSocket channel to `0.0.0.0` and set `token` or `tokenIssueSecret`. The WebSocket channel refuses public binds without a token or token issue secret.
-
-See [`webui.md#lan-access`](./webui.md#lan-access) for LAN setup and [`../webui/README.md`](../webui/README.md) for frontend development.
-
-## Chat App Problems
-
-Before debugging a chat app:
-
-```bash
-nanobot agent -m "Hello!"
-nanobot channels status
-nanobot gateway
-```
-
-Then check:
-
-| Symptom | Check |
-|---|---|
-| Bot never replies | Gateway is not running, the channel is not enabled, or the bot/app token is wrong. |
-| Unknown sender ignored | Configure `allowFrom`, pairing, or the channel-specific allow list. |
-| Telegram fails | Confirm the BotFather token and `allowFrom` user ID. |
-| Discord replies missing | Enable Message Content intent and invite the bot with the required permissions. |
-| WhatsApp or WeChat login expired | Re-run `nanobot channels login whatsapp` or `nanobot channels login weixin`. |
-| Chat app works but WebUI does not | The provider and gateway are likely fine; debug the WebSocket channel separately. |
-
-See [`chat-apps.md`](./chat-apps.md) for channel-specific setup.
-
-## Tool and Workspace Problems
-
-| Symptom | Check |
-|---|---|
-| File access denied | Check `tools.restrictToWorkspace` and whether the target path is inside the active workspace. |
-| Shell commands fail in Docker | Sandbox settings may need Linux capabilities; see [`deployment.md`](./deployment.md). |
-| Web fetch blocked | SSRF protection blocks unsafe targets; use `tools.ssrfWhitelist` only for trusted private networks. |
-| MCP tools missing | Check `tools.mcpServers`, server startup command, environment variables, and tool allow list. |
-| Generated artifacts are missing | Check the active workspace and channel media directory. |
-
-## Memory and Session Problems
-
-| Symptom | Check |
-|---|---|
-| Conversation context seems wrong | Confirm the active workspace and session. WebUI chats and chat app threads may use different sessions. |
-| Memory does not update immediately | Dream consolidation is periodic; recent turns still live in session history. |
-| Old sessions appear after moving config | Session files are stored under `<workspace>/sessions/`; verify the workspace path. |
-| You want one shared session across devices | Set `agents.defaults.unifiedSession` intentionally; otherwise keep separate sessions. |
-
-## Collect Useful Evidence
-
-When opening an issue or asking for help, include:
-
-- install method and `nanobot --version`;
-- operating system and Python version;
-- the command you ran;
-- relevant `nanobot status` output;
-- sanitized config snippets, especially provider, model, channel, and tool settings;
-- gateway logs from `nanobot gateway --verbose`;
-- whether `nanobot agent -m "Hello!"` works.
-
-Never paste real API keys, bot tokens, OAuth tokens, or private chat IDs into public issues.

-# WebUI
-
-The WebUI is nanobot's browser workbench. Use it after a basic CLI reply already
-works, when you want a persistent chat workspace, visible agent activity,
-workspace controls, Apps, Skills, settings, and Automations in one place.
-
-The published `nanobot-ai` wheel already includes the WebUI bundle. You only need
-the `webui/` source directory when you are changing the frontend itself.
-
-## Open the WebUI
-
-First confirm your provider and model can answer:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-Then merge the WebSocket channel into your existing `~/.nanobot/config.json`.
-Set `tokenIssueSecret` to the password you will enter in the WebUI login form:
-
-```json
-{
-  "channels": {
-    "websocket": {
-      "enabled": true,
-      "tokenIssueSecret": "your-webui-password",
-      "websocketRequiresToken": true
-    }
-  }
-}
-```
-
-If you are new to JSON snippets, see
-[`start-without-technical-background.md#how-to-merge-json-snippets`](./start-without-technical-background.md#how-to-merge-json-snippets).
-
-Start the gateway:
-
-```bash
-nanobot gateway
-```
-
-Leave the gateway running and open
-[`http://127.0.0.1:8765`](http://127.0.0.1:8765). The WebUI is served by the
-WebSocket channel on port `8765` by default. The gateway health endpoint,
-`18790` by default, is not the browser UI.
-Enter `tokenIssueSecret` when the WebUI asks for a password.
-
-## What It Is For
-
-| Area | Use it for |
-|---|---|
-| Chat | Start, switch, search, fork, and delete browser sessions |
-| Agent activity | See thinking, tool calls, file activity, command output, and generated artifacts in context |
-| Workspace | Pick the project workspace before asking for file or shell work |
-| Access | Choose the access mode for local capabilities allowed by your gateway configuration |
-| Composer | Send text, images, voice input, slash commands, and `@` mentions for Apps or MCP presets |
-| Apps | Install, test, update, and use local CLI App adapters and MCP presets |
-| Skills | Inspect available built-in and workspace skills before relying on them |
-| Automations | Review, search, run, pause, edit, and delete scheduled and local-trigger agent turns |
-| Settings | Adjust models, providers, image generation, voice, web tools, runtime, and safety options |

-The sidebar is the session switcher. A session keeps its own history, title,
-workspace metadata, and linked automations. Use a new session when you want a
-separate context; use fork when you want to continue from an existing point
-without changing the original thread.
-
-The message timeline shows both user-visible replies and agent activity. Long
-tool or reasoning sections can be expanded when you need the details.
-
-## Workspace and Access
-
-Use the workspace picker before starting project-specific work. This gives the
-agent the right project context for file paths, shell commands, and session
-metadata.
-
-The access control in the composer controls the local capability level for the
-chat. It does not bypass your gateway, provider, shell sandbox, or operating
-system configuration; it only selects among the capabilities that are already
-available to this WebUI session.
-
-## Composer
-
-The composer supports plain messages, image attachments, voice input when
-transcription is configured, slash commands, and `@` mentions for installed Apps
-or MCP presets. The model badge shows the current model or preset and links back
-to model settings when setup is incomplete.
-
-For image generation, configure an image provider first and then use the WebUI
-image mode from the composer. See [`image-generation.md`](./image-generation.md)
-for provider setup and output behavior.
-
-## Apps
-
-Open Apps from the sidebar or settings navigation to manage integrations that
-nanobot can call from a chat. CLI Apps install local adapters that nanobot runs
-on your machine; they do not modify the native apps themselves. MCP presets add
-predefined MCP server configurations.
-
-Some MCP presets connect to hosted keyless endpoints. For example, the Firecrawl
-preset uses Firecrawl's hosted MCP endpoint for search, scrape, crawl, and
-extraction tools without requiring an API key. This does not replace nanobot's
-built-in web search provider; mention the Firecrawl MCP preset with `@` when a
-turn needs Firecrawl's richer web data tools.
-
-After an App or MCP preset is available, mention it from the composer with `@`
-to attach that capability to the next message.
-
-## Skills
-
-The Skills view shows the skill instructions available to the agent, including
-built-in skills and workspace-provided skills. Check this view when you want to
-know whether nanobot already has a focused workflow for a task before you ask it
-to perform that task.
-
-## Automations
-
-Automations are agent turns that run later in a linked chat/session. They should
-be created from the chat, channel, or session where they are supposed to run so
-nanobot keeps the correct target context. When an automation runs, it normally
-delivers the result back to that linked chat.
-
-There are two user-facing automation types:
-
-- Scheduled automations, created by the agent's cron tool, run at a time,
-  interval, or cron expression.
-- Local triggers, created with `/trigger <name>`, run when you call a local
-  command such as `nanobot trigger trg_8K4P2Q9X "Review PR #4502"`.
-
-If a GitHub webhook, CI system, or another service should wake nanobot up, keep
-that webhook/service outside nanobot and have it call the trigger command with
-the final message.
-
-Trigger deliveries use the same workspace as the gateway. They survive gateway
-restarts and are requeued if the process exits before the linked turn completes.
-If the linked session is already running a turn, the local trigger waits until
-that session is idle instead of being injected into the active turn. This is an
-at-least-once local queue, so repeated delivery is possible after an interrupted
-process. A delivered trigger is recorded as an automation turn in the linked
-session; if the agent receives it but the turn fails, Automations marks the run
-failed instead of retrying indefinitely.
-
-For recurring background checks that should stay quiet unless there is something
-useful to report, use the protected heartbeat job by editing `HEARTBEAT.md`
-instead of creating a chat automation.
-
-Use the Automations view to:
-
-- Filter by all, active, paused, needs-attention, or system jobs.
-- Search by task name, message, trigger command, linked chat, schedule, or status.
-- Sort by next run, last run, updated time, or name.
-- Run scheduled automations now.
-- Pause or resume, rename, or delete user-created automations.
-- Copy the CLI command for local triggers.
-- Inspect protected system automations without changing them.
-
-Search accepts plain text and field filters such as `name:backup`,
-`chat:WeChat`, `schedule:09:30`, `cron:"0 23 * * *"`, `trigger`, and
-`status:paused`.
-
-An automation without a linked chat cannot be enabled or run from the WebUI,
-because nanobot would not know where to deliver the scheduled turn. Recreate it
-from the target chat or channel so the automation has complete context.
-
-Local triggers do not have a WebUI "Run now" action because each run needs a
-message. Use the copied `nanobot trigger ...` command and replace `"message"`
-with the content that should be delivered.
-
-## Settings
-
-Settings is the control surface for the browser session and gateway-backed
-runtime configuration. Use it to review or adjust model presets, provider
-visibility, image generation, voice transcription, web tools, Apps, Automations,
-Skills, runtime identity, and advanced safety controls.
-
-Some settings take effect immediately. Runtime settings that affect the gateway
-or agent process may require a restart; the WebUI shows that requirement next to
-the relevant control.
-
-## LAN Access
-
-To open the WebUI from another device on the same network, bind the WebSocket
-channel to all interfaces and set a token or token issue secret:
-
-```json
-{
-  "channels": {
-    "websocket": {
-      "enabled": true,
-      "host": "0.0.0.0",
-      "port": 8765,
-      "tokenIssueSecret": "your-secret-here"
-    }
-  }
-}
-```
-
-The gateway refuses to start with `host` set to `"0.0.0.0"` unless `token` or
-`tokenIssueSecret` is configured. After the gateway starts, open
-`http://<your-ip>:8765` from the other device and enter the secret in the login
-form.
-
-## Troubleshooting
-
-If the page does not open, check these in order:
-
-1. `nanobot agent -m "Hello!"` works in the same Python environment.
-2. The WebSocket channel is enabled in `~/.nanobot/config.json`.
-3. `nanobot gateway` is still running.
-4. You are opening port `8765`, not the gateway health port.
-5. LAN access uses `host: "0.0.0.0"` and a token or token issue secret.
