Fix bugs by changing only what is necessary. Do not bundle unrelated refactors or clean-ups into a feature or bugfix PR. If a refactor is genuinely required, it should be a separate PR targeting `nightly`.

## SSRF Protection
All outbound HTTP requests from agent tools must pass through `validate_url_target` (`security/network.py`). By default it blocks RFC1918 private addresses, link-local ranges, and cloud metadata endpoints (including `169.254.169.254`).
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.

## Branching Strategy
## Contribution Flow
We use a two-branch model to balance stability and exploration:
### What Should I Open a PR For?
| Branch | Purpose | Stability |
|--------|---------|-----------|
| `main` | Stable releases | Production-ready |
| `nightly` | Experimental features | May have bugs or breaking changes |
### Which Branch Should I Target?
**Target `nightly` if your PR includes:**
PRs are welcome for:
- New features or functionality
- Refactoring that may affect existing behavior
- Changes to APIs or configuration
**Target `main` if your PR includes:**
- Bug fixes with no behavior changes
- Documentation improvements
- Minor tweaks that don't affect functionality
- Refactoring that is clearly scoped and easy to review
- Changes to APIs or configuration, when the impact is documented
**When in doubt, target `nightly`.** It is easier to move a stable idea from `nightly`
to `main` than to undo a risky change after it lands in the stable branch.
For riskier or larger changes, please open an issue or draft PR early so the
shape of the work can be discussed before the implementation grows too large.
### Starting Work
Before making changes, sync the target branch and create a topic branch from it.
For stable bug fixes and documentation-only changes, start from the latest `main`.
For experimental work, start from the latest `nightly`.
Before making changes, sync your local checkout and create a topic branch.
```bash
git fetch upstream
@ -65,28 +53,6 @@ Keep unrelated local changes out of the topic branch. If your checkout already h
work in progress, use a separate worktree or finish that work before starting a
new branch.
### How Does Nightly Get Merged to Main?
We don't merge the entire `nightly` branch. Instead, stable features are **cherry-picked** from `nightly` into individual PRs targeting `main`:
```
nightly ──┬── feature A (stable) ──► PR ──► main
├── feature B (testing)
└── feature C (stable) ──► PR ──► main
```
This happens approximately **once a week**, but the timing depends on when features become stable enough.
### Quick Summary
| Your Change | Target Branch |

| Bug fix | `main` |
| Documentation | `main` |
| Refactoring | `nightly` |
| Unsure | `nightly` |

> If you want the most stable day-to-day experience, install from PyPI or with `uv`.
**Install from source**
Pick **one** install method:
Prerequisites: Python 3.11 or newer. Git is only needed for a source install; Node.js/Bun are only needed if you are developing the WebUI itself.
If terminals, API keys, or config files are new to you, use the guided zero-background walkthrough in [Start Without Technical Background](./docs/start-without-technical-background.md) instead of this compact README path.
**One-command setup**
macOS / Linux:
```bash
git clone https://github.com/HKUDS/nanobot.git
cd nanobot
pip install -e .
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)"
```
Windows PowerShell:
```powershell
irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
```
The default command installs or upgrades `nanobot-ai` from PyPI, then starts `nanobot onboard --wizard`. If you finish the wizard and save the config, skip the manual initialize/configure steps below and go straight to **Test one message**.
To preview the plan without changing your environment, pass `--dry-run`; combine it with `--dev` when you want to preview the main-branch install.
```bash
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)" -- --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
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)" -- --dev
```
```powershell
& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dev
```
If you prefer to inspect the script first, open [`scripts/install.sh`](./scripts/install.sh) or [`scripts/install.ps1`](./scripts/install.ps1).

## 🚀 Quick Start
**1. Initialize**
Skip this step if the one-command setup already started the wizard and you saved the config there.
```bash
nanobot onboard
```
Use `nanobot onboard --wizard` if you prefer an interactive setup.
**2. Configure** (`~/.nanobot/config.json`)
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.
Skip this step if you already configured provider and model settings in the wizard.
*Set your API key* (e.g. [OpenRouter](https://openrouter.ai/keys), recommended for global users):
`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.
The example below uses [OpenRouter](https://openrouter.ai/keys) only so the JSON has concrete names. Provider examples are recipes, not rankings or endorsements. If you use another provider, replace the provider config key, API key, preset provider name, and model ID together.
*Set your API key*:

}
```
*Set your model* (optionally pin a provider — defaults to auto-detection):
*Set a model preset and make it active*:
```json
{
"modelPresets": {
"primary": {
"label": "Primary",
"provider": "openrouter",
"model": "anthropic/claude-opus-4.5",
"maxTokens": 8192,
"contextWindowTokens": 65536,
"temperature": 0.1
}
},
"agents": {
"defaults": {
"provider": "openrouter",
"model": "anthropic/claude-opus-4-6"
"modelPreset": "primary"
}
}
}
```
**3. Chat**
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`.
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. Test one 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
```

| Change provider or add fallbacks | [`provider-cookbook.md`](./provider-cookbook.md) | Keep `modelPresets` named and set `agents.defaults.modelPreset` |
| Understand before operating long-term | [`concepts.md`](./concepts.md) | Know what config, workspace, gateway, sessions, memory, and tools mean |
| Diagnose a new failure | [`troubleshooting.md`](./troubleshooting.md) | Start with `nanobot status`, then `nanobot agent -m "Hello!"` |

## 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.

# Architecture
This page maps nanobot's runtime behavior to source files. Use it when you are debugging internals, reviewing a PR, adding a provider/channel/tool, or trying to understand where a user-visible behavior comes from.
For the product-level mental model, read [`concepts.md`](./concepts.md) first.
## Core Flow

```
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/README.md`](../webui/README.md) for WebUI use and 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.

## Periodic Tasks
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.
Periodic tasks 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 results to your most recently active chat channel. If there are no active tasks, the heartbeat is skipped silently.
**Setup:** edit `~/.nanobot/workspace/HEARTBEAT.md` (created automatically by `nanobot onboard`):
```markdown
## Active Tasks
- [ ] Check weather forecast and send a summary
- [ ] Scan inbox for urgent emails
- Check weather forecast and send a summary
- Scan inbox for urgent emails
```
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.

## 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 `nanobot gateway` or `nanobot serve`.
## Setup
| Command | Description |
|---|---|
| `nanobot onboard` | Initialize or refresh the default config and workspace |
| `nanobot onboard --wizard` | Use the interactive setup wizard |
| `nanobot onboard --config <path> --workspace <path>` | Initialize or refresh a specific instance |
Default paths:
| Path | Default |
|---|---|
| Config | `~/.nanobot/config.json` |
| Workspace | `~/.nanobot/workspace/` |
## Agent CLI
| Command | Description |
|---|---|
| `nanobot agent -m "Hello!"` | Send one message and exit |
| `nanobot agent` | Start interactive terminal chat |
| `nanobot agent --session <id>` | Use a specific session key |
| `nanobot agent --workspace <path>` | Override workspace |
| `nanobot agent --config <path>` | Use a specific config file |
| `nanobot agent --no-markdown` | Print plain text instead of Rich-rendered Markdown |
| `nanobot agent --logs` | Show runtime logs while chatting |
Interactive mode exits with `exit`, `quit`, `/exit`, `/quit`, `:q`, or `Ctrl+D`.
## Gateway
`nanobot gateway` starts enabled chat channels, WebUI/WebSocket when configured, cron-backed system jobs, Dream, heartbeat, and the health endpoint.
| Command | Description |
|---|---|
| `nanobot gateway` | Start the gateway 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 |
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.
## OpenAI-Compatible API
| Command | Description |
|---|---|
| `nanobot serve` | Start `/v1/chat/completions`, `/v1/models`, and `/health` |
| `nanobot serve --host <host>` | Override API bind host |

Default API endpoint:
```text
http://127.0.0.1:8900
```
See [`openai-api.md`](./openai-api.md) for request examples.
## Status
```bash
nanobot status
```
Shows the default config path, workspace path, active model, and provider summary. This command does not currently accept `--config`; use explicit `--config` and `--workspace` on `agent`, `gateway`, or `serve` when debugging a specific instance.
## Channels
| Command | Description |
|---|---|
| `nanobot channels status` | Show configured channel status |
| `nanobot channels status --config <path>` | Show channel status for a specific config |
| `nanobot channels login <channel>` | Run interactive login for supported channels |
| `nanobot channels login <channel> --force` | Re-authenticate even if credentials already exist |
| `nanobot channels login <channel> --config <path>` | Use a specific config file |
Examples:
```bash
nanobot channels login whatsapp
nanobot channels login weixin
nanobot channels status
```
See [`chat-apps.md`](./chat-apps.md) for channel-specific setup.
## Provider OAuth
| Command | Description |
|---|---|
| `nanobot provider login openai-codex` | Authenticate OpenAI Codex provider |
| `nanobot provider login github-copilot` | Authenticate GitHub Copilot provider |
| `nanobot provider logout openai-codex` | Remove OpenAI Codex OAuth state |
| `nanobot provider logout github-copilot` | Remove GitHub Copilot OAuth state |
See [`providers.md`](./providers.md#oauth-providers) for when OAuth providers need explicit provider/model selection.
## Useful First Checks
```bash
nanobot --version
nanobot status
nanobot agent -m "Hello!"
```
If these fail, use [`troubleshooting.md`](./troubleshooting.md) before debugging WebUI, chat apps, Docker, systemd, or SDK integrations.

# Concepts
Use this page when you want to understand nanobot before changing advanced settings. It explains the moving parts without requiring you to read the source first.
If you want source-file ownership and extension points, read [`architecture.md`](./architecture.md) after this page.
## 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 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 creates workspace-scoped cron storage at `<workspace>/cron/jobs.json` 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 useful results to the most recently active chat target.
User-created reminders use the same cron service but are not the same as the protected heartbeat system job.

# 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, WebUI, and desktop 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.

# Provider Cookbook
This page is for cases where you already know what you want to connect and need a pasteable setup. Each recipe shows what to set, what to run, and what a failure usually means.
If this is your first install and terminal commands are new to you, start with [`start-without-technical-background.md`](./start-without-technical-background.md). If you want the field-by-field explanation, read [`providers.md`](./providers.md) and then [`configuration.md#providers`](./configuration.md#providers).
Most examples below are snippets to merge into `~/.nanobot/config.json`. Keep any existing sections you still need, and replace placeholder keys such as `${OPENROUTER_API_KEY}` with environment-variable references or real values only on your own machine.
Recipes are examples, not rankings. Pick the recipe that matches the credential, endpoint, and model ID you already intend to use.
## 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 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 |
| 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 primary model plus one or more backups | [Fallback Presets](#recipe-fallback-presets) | Named presets in `modelPresets`, referenced from `agents.defaults.fallbackModels` |
| 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` or `nanobot onboard --wizard` once so `~/.nanobot/config.json` exists.
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: 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"`.
## 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"`.
## 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"
}
},
"modelPresets": {
"local": {
"label": "LM Studio",
"provider": "lm_studio",
"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. |
| 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 `${ENV_VAR}` for secrets. |
| `apiBase` | `providers.<provider>.apiBase` | HTTP base URL of the provider endpoint. |
You usually omit `apiBase` for hosted built-in providers such as OpenRouter, Anthropic direct, OpenAI direct, Groq, or Bedrock because nanobot knows their default endpoints. Set `apiBase` for `custom`, local OpenAI-compatible servers, provider proxies, regional endpoints, or subscription endpoints. Include the API version path when the endpoint requires it, for example `https://api.example.com/v1` or `http://localhost:11434/v1`.
## Common Provider Patterns
### OpenRouter Gateway
Gateway-style setup for model IDs served through OpenRouter.
```json
{
"providers": {
"openrouter": {
"apiKey": "${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.
### Anthropic Direct
```json
{
"providers": {
"anthropic": {
"apiKey": "${ANTHROPIC_API_KEY}"
}
},
"modelPresets": {
"primary": {
"provider": "anthropic",
"model": "claude-opus-4-5",
"maxTokens": 8192,
"contextWindowTokens": 200000
}
},
"agents": {
"defaults": {
"modelPreset": "primary"
}
}
}
```
Anthropic direct uses the native Anthropic provider. Do not use an OpenRouter model ID unless the provider is OpenRouter.
### OpenAI Direct
```json
{
"providers": {
"openai": {
"apiKey": "${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 OpenAI-compatible endpoints that are 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`.
### 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.
## 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 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",
"maxTokens": 8192,
"contextWindowTokens": 200000,
"temperature": 0.1
}
},
"agents": {
"defaults": {
"modelPreset": "fast"
}
}
}
```
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) |
For the complete provider table and advanced provider-specific notes, see [`configuration.md#providers`](./configuration.md#providers).

Use nanobot as a library — no CLI, no gateway, just Python.
Before debugging SDK code, prove the same config works from the CLI:
```bash
nanobot agent -m "Hello!"
```
`Nanobot.from_config()` reuses your normal `~/.nanobot/config.json`, so provider, model, tools, and workspace behavior match the CLI unless you override them.

`Nanobot.from_config()` reuses your normal `~/.nanobot/config.json`, so the SDK follows the same provider, model, tools, and workspace defaults as the CLI unless you override them.
Use `async with` when possible so MCP connections and background cleanup work are closed before the event loop exits. If you manage the instance manually, call `await bot.aclose()` in a `finally` block.

# Install and Quick Start
## Install
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.
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 OpenRouter only so the snippets are concrete; 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]
> 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`.
> 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.
**Install from source** (latest features, experimental changes may land here first; recommended for development)
## 1. Install
Pick one install method.
**One-command setup:**
```bash
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)"
```
On Windows PowerShell:
```powershell
irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
```
The default command installs or upgrades `nanobot-ai` from PyPI, then starts `nanobot onboard --wizard`. If you finish the wizard and save the config, skip the manual initialize/configure steps and go straight to [Check the Setup](#4-check-the-setup).
To preview the plan without changing your environment, pass `--dry-run`; combine it with `--dev` when you want to preview the main-branch install.
```bash
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)" -- --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
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)" -- --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
```
**Latest source checkout:**
```bash
git clone https://github.com/HKUDS/nanobot.git
cd nanobot
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
python -m pip install -e .
nanobot --version
```
**uv**
If your shell cannot find `nanobot` after a pip install, run the module form:
```bash
uv tool upgrade nanobot-ai
nanobot --version
python -m nanobot --version
python -m nanobot onboard
```
**Using WhatsApp?** Rebuild the local bridge after upgrading:
On Windows, `~` in the docs means your user profile directory, for example `C:\Users\you`.
```bash
rm -rf ~/.nanobot/bridge
nanobot channels login whatsapp
```
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`.
## Quick Start
## 2. Initialize
> [!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**
Skip this section if the one-command setup already started the wizard and you saved the config there.
```bash
nanobot onboard
```
Use `nanobot onboard --wizard` if you want the interactive setup wizard.
Use the wizard if you prefer prompts instead of editing JSON by hand:
**2. Configure** (`~/.nanobot/config.json`)
```bash
nanobot onboard --wizard
```
Configure these **two parts** in your config (other options have defaults).
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:**
*Set your API key* (e.g. OpenRouter, recommended for global users):
```json
{
"providers": {
@ -83,22 +133,191 @@ Configure these **two parts** in your config (other options have defaults).
}
```
*Set your model* (optionally pin a provider — defaults to auto-detection):
**Model preset:**
```json
{
"modelPresets": {
"primary": {
"label": "Primary",
"provider": "openrouter",
"model": "anthropic/claude-opus-4.5",
"maxTokens": 8192,
"contextWindowTokens": 65536,
"temperature": 0.1
}
},
"agents": {
"defaults": {
"model": "anthropic/claude-opus-4-5",
"provider": "openrouter"
"modelPreset": "primary"
}
}
}
```
**3. Chat**
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 `openrouter` | `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": {
"openrouter": {
"apiKey": "${OPENROUTER_API_KEY}"
}
}
}
```
## 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. Test One Message
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
```
That's it! You have a working AI agent in 2 minutes.
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 an OpenRouter model preset named "primary".
Tell me exactly what changed and whether I need to run /restart.
```
Exit interactive mode with `exit`, `quit`, `/exit`, `/quit`, `:q`, or `Ctrl+D`.
## 6. 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/README.md`](../webui/README.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
```
**uv:**
```bash
uv tool upgrade nanobot-ai
nanobot --version
```
**Source checkout:**
```bash
git pull
python -m pip install -e .
nanobot --version
```
If you use WhatsApp, rebuild the local bridge after upgrading:
```bash
rm -rf ~/.nanobot/bridge
nanobot channels login whatsapp
```
## First-Run Troubleshooting
| 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`. |
For a fuller diagnosis flow, see [`troubleshooting.md`](./troubleshooting.md).

# 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. Do not connect Telegram, Discord, WebUI, Docker, local models, or deployment yet. Those are easier after the first reply works.
## What You Are Setting Up
You will see these words during setup:
| 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. |
| Provider | The service that owns the API key or local model endpoint. |
| Model | The AI model ID that the provider can run. |
| Config file | The settings file nanobot reads when it starts. |
| Wizard | An interactive terminal menu that edits the config file for you. |
| Model preset | A named model choice in the config file. |
| `apiBase` | The HTTP address of a provider endpoint. Leave it blank unless your provider, proxy, or local server tells you to set one. |
## 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. The steps below use OpenRouter only as a concrete example so the commands and wizard choices have real names; it is not a ranking, default choice, or endorsement.
If you use another provider, keep the same shape but replace the provider name, API key, and model ID with values from that provider. [`provider-cookbook.md`](./provider-cookbook.md) has copyable snippets for several common patterns.
For the example path:
1. Open [openrouter.ai/keys](https://openrouter.ai/keys).
2. Create or copy an API key.
3. Keep the key private.
An OpenRouter key usually starts with `sk-or-v1-`. Other providers use different key shapes. Keep the key nearby because the setup wizard will ask you to paste it.
## 4. Install nanobot
The easiest path is the one-command installer. It installs or upgrades nanobot, then starts the setup wizard.
**macOS / Linux**
```bash
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)"
```
**Windows PowerShell**
```powershell
irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
```
These commands install the stable PyPI package. To preview what the installer would do without changing your environment, pass `--dry-run`:
```bash
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)" -- --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
sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)" -- --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 the manual install command below.
If you prefer to install manually, run:
```bash
python -m pip install nanobot-ai
```
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 configure?
[P] LLM Provider
[M] Model Presets
[C] Chat Channel
[H] Channel Common
[A] Agent Settings
[I] API Server
[G] Gateway
[T] Tools
[V] View Configuration Summary
[S] Save and Exit
[X] Exit Without Saving
```
Move through the wizard like this:
| When you see | Do this |
|---|---|
| A menu | Use the arrow keys to highlight an option, then press `Enter`. |
| A text field | Type or paste the value, then press `Enter`. |
| A field you do not need | Keep the shown default or leave it blank, then press `Enter`. |
| A back option | Choose it to return to the previous menu. |
For the first setup, only configure the model provider and one model preset.
If you are following the OpenRouter example:
1. Choose `[P] LLM Provider`.
2. Select OpenRouter.
3. Paste your OpenRouter API key.
4. Keep the default `apiBase`, or leave it blank if the wizard shows no default. Only change it if OpenRouter or your deployment guide explicitly tells you to set one.
5. Return to the main menu.
6. Choose `[M] Model Presets`.
7. Add or edit a preset named `primary`.
8. Set:
```text
label: Primary
provider: openrouter
model: anthropic/claude-sonnet-4.5
maxTokens: 4096
contextWindowTokens: 65536
temperature: 0.1
```
If OpenRouter says your account cannot use that model, use another OpenRouter model ID that your account can access.
If you are using another provider, use the same wizard choices but substitute that provider's values:
| Wizard field | What to enter |
|---|---|
| Provider menu | The provider that owns your API key or endpoint. |
| API key | The key from that provider, or leave it blank only if the provider does not use one. |
| `apiBase` | Leave blank unless the provider docs, proxy docs, or local server docs give you a URL. |
| Preset `provider` | The nanobot provider name, such as the one shown in [`provider-cookbook.md`](./provider-cookbook.md). |
| Preset `model` | A model ID that provider can actually serve. |
| Preset name | `primary` is fine for the first setup. |
Then 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. |
## 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": {
"openrouter": {
"apiKey": "sk-or-v1-your-key-here"
}
},
"channels": {
"websocket": {
"enabled": 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 Config Fallback
Use this only if the wizard is unavailable or you prefer opening the file yourself.
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": {
"openrouter": {
"apiKey": "sk-or-v1-your-key-here"
}
},
"modelPresets": {
"primary": {
"label": "Primary",
"provider": "openrouter",
"model": "anthropic/claude-sonnet-4.5",
"maxTokens": 4096,
"contextWindowTokens": 65536,
"temperature": 0.1
}
},
"agents": {
"defaults": {
"modelPreset": "primary"
}
}
}
```
Replace `sk-or-v1-your-key-here` with your real OpenRouter key.
If you use another provider, replace `openrouter`, `sk-or-v1-your-key-here`, and the `model` value with that provider's values. If the provider needs `apiBase`, add it under that provider's config block.
Save the file.
## 7. Send the First Message
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.
Run:
```bash
nanobot agent -m "Hello!"
```
If that works, nanobot is installed and can call the model.
You should see a normal assistant reply in the terminal. 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 agent -m "Hello!"
```
Use `python3 -m nanobot agent -m "Hello!"` or `py -m nanobot agent -m "Hello!"` if that is the Python command that worked in step 2.
Once this works, nanobot can help with its own next setup step. Run `nanobot agent`, 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 enable the browser UI, 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` | The model ID is not available through the selected provider or your account cannot use it. |
| `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.
- WebUI and chat apps: first prove `nanobot agent -m "Hello!"`.
- 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
1. Add this snippet to `~/.nanobot/config.json`. Merge it into the existing file instead of replacing the whole file:
```json
{ "channels": { "websocket": { "enabled": true } } }
```
2. Run:
```bash
nanobot gateway
```
3. Leave that terminal open.
4. 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/README.md`](../webui/README.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 `nanobot agent -m "Hello!"` works;
- 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 manual install: `python -m pip install nanobot-ai`, replacing `python` with `python3` if needed. |
| `irm` is not recognized | PowerShell could not run the download helper. Use manual install: `python -m pip install nanobot-ai`, or `py -m pip install nanobot-ai` on Windows. |
| 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` | The installer tries `python -m ensurepip --upgrade` first. 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. The one-command installer retries with `--user`; if that still fails, create a virtual environment or install with `uv`/`pipx`. |
| Installer chose the wrong Python | Set `PYTHON` before running the installer, such as `PYTHON=python3 sh -c "$(curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh)"` or `$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`. |
| 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/README.md`](../webui/README.md) for LAN and development setup.
## 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.
If you find a docs mistake, outdated command, or confusing step, please open an issue: <https://github.com/HKUDS/nanobot/issues>.

"""Wrap a primary provider and transparently failover to fallback models.
When the primary model returns an error and no content has been streamed yet,
the wrapper tries each fallback model in order. Each fallback model may
reside on a different provider — a factory callable creates the underlying
provider on-the-fly.
When the primary model returns a fallbackable error before content has been
streamed, the wrapper tries each fallback model in order. Streamed timeout
errors are the recovery exception: the caller may close the current stream
segment, then the wrapper continues failover with later deltas in a new
segment. Each fallback model may reside on a different provider — a factory
callable creates the underlying provider on-the-fly.
Key design:
- Failover is request-scoped (the wrapper itself is stateless between turns).
- Skipped when content was already streamed to avoid duplicate output.
- Skipped when content was already streamed to avoid duplicate output,

Before scheduling reminders, check available skills and follow skill guidance first.
Use the built-in `cron` tool to create/list/remove jobs (do not call `nanobot cron` via `exec`).
Get USER_ID and CHANNEL from the current session (e.g., `8281248569` and `telegram` from `telegram:8281248569`).

- Get USER_ID and CHANNEL from the current session (e.g., `8281248569` and `telegram` from `telegram:8281248569`).
**Do NOT just write reminders to MEMORY.md** — that won't trigger actual notifications.
## Heartbeat Tasks
`HEARTBEAT.md` is checked periodically when registered as a cron job. Use the built-in `cron` tool to schedule it (e.g. `cron add --name heartbeat --schedule "every 30m" --message "Check HEARTBEAT.md"`).
`HEARTBEAT.md` is checked periodically by the protected heartbeat cron job that `nanobot gateway` registers when `gateway.heartbeat.enabled` is true. Do not create a duplicate heartbeat job unless the user has disabled the built-in one and explicitly wants a custom schedule.
- Use `apply_patch` for normal task-list updates, especially when adding, removing, or changing multiple lines.
- Use `edit_file` only for small exact replacements copied from the current `HEARTBEAT.md`.
- Use `write_file` for first creation or intentional full-file rewrites.
When the user asks for a recurring/periodic task, update `HEARTBEAT.md` and register it via `cron` instead of creating a one-time reminder.
When the user asks for a recurring/periodic heartbeat task, update `HEARTBEAT.md` instead of creating a one-time reminder. Use the built-in `cron` tool for separate reminders or custom schedules that should not be part of the heartbeat task list.

- Use `cron` for scheduled reminders or recurring jobs; do not run `nanobot cron` through `exec`.
- For heartbeat tasks, register `HEARTBEAT.md` as a cron job according to the agent instructions.
- For heartbeat tasks, update `HEARTBEAT.md`; the default gateway heartbeat cron job handles periodic checks when enabled.
