fix(webui): emphasize temporary chat expiry

convert_messages() emitted reasoning items with ``content`` as a plain
string whenever preserve_reasoning was enabled (the DeepSeek spec).
DeepSeek's Responses gateway rejects that shape with a serde error
("input: invalid type: string ..., expected a sequence"), which surfaced
only after token consolidation cleared provider_state and forced the
full-history conversion path; replayed server items already carry list
content, which is why normal multi-turn requests never failed. Serialize
reasoning content as a list of output_text parts, matching the OpenAI
Responses schema and DeepSeek's accepted wire shape (verified live against
api.deepseek.com/responses).

The serde fallback classifier introduced in the previous commit remains as
a last-resort safeguard for any remaining wire incompatibility.

Tests: extend test_preserves_deepseek_reasoning_content to the array shape;
add a full-history regression with the observed failing item, a
replay/consolidation regression covering both replayed and converted
reasoning items, and provider-level request fixtures for both paths.
Full suite: 5773 passed, 22 skipped (only the known local-only
channels/sms packaging failure remains).

 A bugfix should make the protected invariant clear, change the smallest surface that enforces it, and add only the closest regression test. If a diff starts changing ownership boundaries or mixing behavior changes with clean-up, split it before it becomes hard to review.
 
+## Type dynamic boundaries at the edge
+
+Wire payloads, persisted records, and third-party SDK objects are untrusted dynamic boundaries. Prefer a parser or small normalizer at the owning edge, and use `TypedDict` for stable dictionary shapes, so validation happens once and internal code receives a concrete type. Do not spread raw dynamic dictionaries or SDK objects through the core.
+
+Stable first-party dependencies must be typed where they are stored or passed. Do not declare an internal service, context field, or callback result as `Any` and then recover its real type with consumer-side casts. Use the concrete type or a narrow `Protocol`; reserve `Any` for genuinely dynamic boundaries.
+
+`typing.cast` performs no runtime validation. Every new cast must be supported by a runtime check on the same path or by an explicit invariant that is clear from construction and control flow (and documented locally when it is not obvious). If input can violate the claimed type, handle that invalid case before casting; never use `cast` only to silence BasedPyright.

 ## Explicit over magical
 
 Configuration must be declared explicitly in `config/schema.py` Pydantic models. Error handling should raise clear exceptions rather than silently correcting bad input. Provider auto-detection exists, but every resolution path must be traceable from the factory to the concrete provider class.

+For direct requests, the only escape hatch is `configure_ssrf_whitelist(cidrs)`, which reads from `config.tools.ssrf_whitelist` at load time. An explicitly configured `providers.<name>.proxy` is a separate user-authorized trust boundary for provider requests and provider-returned image URL downloads. Those downloads still reject malformed URLs and locally identifiable private/internal targets on every redirect, but hostnames unavailable to local DNS are delegated to the trusted proxy. The user-selected proxy owns final DNS resolution and network egress policy.
 
 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.

 ## 🚀 Quick Start
 
-**1. Initialize**
-
-Skip this step if the one-command setup already started the wizard and Quick Start finished there.
-
-```bash
-nanobot onboard
-```
-
-Use `nanobot onboard --wizard` if you prefer an interactive setup.
-
-**2. Configure** (`~/.nanobot/config.json`)
-
-Skip this step if you already configured provider and model settings in the wizard.
-
-`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 a generic OpenAI-compatible `custom` provider so the compact path does not recommend one hosted service. Provider examples are recipes, not rankings or endorsements. For copyable provider-specific setup, see [Provider Cookbook](./docs/provider-cookbook.md).
-
-*Set your API key*:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "your-api-key",
-      "apiBase": "https://api.example.com/v1"
-    }
-  }
-}
-```
-
-*Set a model preset and make it active*:
-
-```json
-{
-  "modelPresets": {
-    "primary": {
-      "label": "Primary",
-      "provider": "custom",
-      "model": "model-id-from-your-provider",
-      "maxTokens": 8192,
-      "contextWindowTokens": 200000,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  }
-}
-```
-
-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. Open the WebUI**
-
-Start the browser workbench:
+**Open nanobot in your browser**
 
 ```bash
 nanobot webui
 ```
 
-`nanobot webui` prepares the local WebSocket channel if needed, starts the gateway, and opens `http://127.0.0.1:8765`. It binds the first-run WebUI to `127.0.0.1` by default, so it is not exposed to your LAN. Prefer not to keep a terminal open? Use `nanobot webui --background`, then manage the gateway with `nanobot gateway status`, `logs`, `restart`, and `stop`.
+This is the recommended first run. The launcher creates the config and workspace when needed, safely enables the local WebSocket channel after confirmation, starts the gateway, and opens [`http://127.0.0.1:8765`](http://127.0.0.1:8765). A fresh install can open before a model is configured, so setup continues in the browser instead of beginning in a JSON file. The first-run WebUI binds to localhost by default and is not exposed to your LAN.
 
-For manual or terminal-only setup, test one CLI message:
+**Your first three steps**
+
+1. Open **Settings → Models** and choose a provider, credential, and model.
+2. Start a new topic and send `Hello!` to verify the connection.
+3. Before project work, choose the intended workspace and access mode from the composer.
+
+Any normal reply means the provider, model, workspace, and browser gateway are working together.
+
+**Keep nanobot running after you close the terminal**
 
 ```bash
-nanobot status
-nanobot agent -m "Hello!"
+nanobot webui --background
 ```
 
-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.
+This starts the same full gateway as `nanobot webui`, opens the browser, and leaves channels and automations running after the launcher exits. Complete first-time model setup with foreground `nanobot webui` before switching to background mode.
 
-If that works, start an interactive chat:
+```bash
+nanobot gateway status
+nanobot gateway logs
+nanobot gateway restart
+nanobot gateway stop
+```
+
+**Prefer a gateway-first workflow?**
+
+```bash
+nanobot gateway
+```
+
+This skips WebUI setup and browser opening, then runs the same complete gateway in the current terminal. It is the familiar entry point if you are coming from OpenClaw or already operate agents as long-lived services. The WebUI remains available when its channel is configured; open it manually when needed.
+
+Use `nanobot gateway --background` for the same direct entry point without keeping the terminal attached. For automatic startup and supervision by the operating system, see [Deployment](./docs/deployment.md).
+
+**Prefer to work entirely in the terminal?**
 
 ```bash
 nanobot agent
 ```
 
-Need help with `PATH`, API keys, provider/model matching, or JSON errors? See the fuller [Install and Quick Start](./docs/quick-start.md) and [Troubleshooting](./docs/troubleshooting.md).
+This opens an interactive terminal chat with the same configured model, workspace, and tools while keeping its own CLI session history. It does not open a browser or keep chat channels and automations running after you exit. Type `exit` or press `Ctrl+C` when you are done.
+
+For one request and an immediate exit, use:
+
+```bash
+nanobot agent -m "Hello!"
+```
+
+The one-shot form is useful for a quick provider check, shell scripts, and local automation. If you have not configured a model yet, run `nanobot webui` and open **Settings → Models** first.
+
+Need manual JSON, another device on your LAN, or help with provider/model matching? Continue with [Install and Quick Start](./docs/quick-start.md), [WebUI](./docs/webui.md), or [Troubleshooting](./docs/troubleshooting.md).
+
+If nanobot worked for you, a star on GitHub is the simplest way to support the project.

+- switch models and workspaces without leaving the conversation;
+- configure providers, chat channels, Apps, Skills, and Automations from one place.
 
-The command enables the local WebSocket channel after confirmation, starts the gateway, and opens [`http://127.0.0.1:8765`](http://127.0.0.1:8765). To open it from another device on your LAN, see [WebUI docs -> LAN access](./docs/webui.md#lan-access).
-
-The WebUI is served by the WebSocket channel on port `8765` by default. The gateway's `18790` port is for the health endpoint, not the browser UI.

 🐈 nanobot stays lightweight by centering everything around a small agent loop: messages come in from chat apps, the LLM decides when tools are needed, and memory or skills are pulled in only as context instead of becoming a heavy orchestration layer. That keeps the core path readable and easy to extend, while still letting you add channels, tools, memory, and deployment options without turning the system into a monolith.

+Use these docs to get a working agent first, then open a task guide only when you need the next capability. Source-level design and extension details are kept in the contributor section.
 
-If you have never used a terminal or edited a config file before, start with [`start-without-technical-background.md`](./start-without-technical-background.md). Otherwise, start with [`quick-start.md`](./quick-start.md), open the browser workbench with `nanobot webui`, and use terminal checks when you need lower-level diagnosis.
-
-Most JSON examples in these docs are snippets to merge into `~/.nanobot/config.json`, not full replacement files.
-
-Provider examples are concrete walkthroughs, not rankings or endorsements. Use the provider whose key, endpoint, and model ID you actually control.
-
-If you find a docs mistake, outdated command, or confusing step, please open an issue: <https://github.com/HKUDS/nanobot/issues>.

+| Your situation | Read this | You are done when... |
 |---|---|---|
-| Start with no technical background | [`start-without-technical-background.md`](./start-without-technical-background.md) | One-command setup, terminal basics, config, API keys, and the first reply |
-| Install and get the first reply | [`quick-start.md`](./quick-start.md) | A working CLI agent and a known-good config path |
-| Understand how the pieces fit | [`concepts.md`](./concepts.md) | Mental model for config, workspace, gateway, channels, tools, memory, and sessions |

+| You are comfortable running commands | [Install and Quick Start](./quick-start.md) | `nanobot status` is healthy and the WebUI or CLI can get one reply |
+| Something already failed | [Troubleshooting](./troubleshooting.md) | You have isolated the problem to install, config, model, gateway, channel, or tool access |
 
-## Task Guides
+The recommended first-run path is:
 
-Use these pages when you know the workflow you want and do not want to scan the
-full reference first.
+1. Install nanobot.
+2. Let the installer open `nanobot webui` on a fresh local desktop.
+3. Configure a provider and model in **Settings → Models**.
+4. Send `Hello!` before configuring anything else.
+
+Most people do not need to edit JSON for the first run. The WebUI handles the initial provider, model, and local browser settings. SSH, headless, existing-config, and older-release installs retain `nanobot onboard --wizard` as a terminal fallback. After the WebUI opens, use **Settings** for models and built-in capabilities, **Settings → Channels** for chat apps, and **Apps** for CLI App or MCP integrations.

+# Channel Package Guide
+
+Use this guide to add a self-contained channel package to the nanobot repository. A channel is part of nanobot when its package lives at `nanobot/channels/<channel>/`; there is no separate external channel-plugin path.
+
+> **Breaking change:** nanobot no longer discovers the `nanobot.channels` Python entry-point group. Move an entry-point implementation into `nanobot/channels/<channel>/` with a package-owned manifest, runtime, tests, and optional WebUI contribution.
+
+## How It Works
+
+When `nanobot gateway` starts, nanobot scans the packages under `nanobot/channels/` and loads each dependency-free `ChannelPlugin` descriptor from `manifest.py`.
+
+If a matching config section has `"enabled": true`, the channel is instantiated and started.
+
+## Ownership and Sources of Truth
+
+| Concern | Owner and source of truth |
+|---------|---------------------------|
+| Runtime behavior and platform SDK use | `runtime.py` and package-local helpers |
+| Python package requirements | `ChannelPlugin.dependencies` in `manifest.py` |
+| Writable settings fields, types, defaults, requirements, secret handling, and validation | `ChannelPlugin.setup` in `manifest.py` |
+| Persisted config expansion, instance updates, and runtime naming | `ChannelPlugin.management` backed by a dependency-free module |
+| Interactive setup connections and their short-lived state | `ChannelPlugin.connector` backed by package-local `connect.py` |
+| Reusable local login-state detection | `ChannelPlugin.management.local_state_present` backed by package-local code |
+| Discovery metadata and lazy runtime target | `PLUGIN` in `manifest.py` |
+| WebUI structure, components, URLs, field keys, actions, and preset values | `webui/index.ts` or `webui/index.tsx` |
+| Channel-specific user-facing copy | `webui/locales/<locale>.json` |
+| Generic settings-shell copy shared by every channel | `webui/src/i18n/locales/<locale>/common.json` |
+
+Keep one source of truth for each concern. In particular, the backend setup contract decides what may be written, the TypeScript contribution decides how those fields are presented, and locale JSON supplies the channel-specific words shown to users.
+
+## Quick Start
+
+We'll build a minimal webhook channel that receives messages via HTTP POST and sends replies back.

+
+The package directory, `PLUGIN.name`, runtime class name, and config section must all use `webhook`. Channel names use a portable ASCII package identifier: they start with a letter and contain only letters, digits, or underscores.
+
+Declare runtime requirements directly in `ChannelPlugin.dependencies`. Do not add channel requirements to the root `pyproject.toml`: the package manifest is the source of truth used by the CLI, WebUI, and gateway startup. Keep the manifest and anything it imports free of the optional SDK itself.
+
+### 2. Configure
+
+```bash
+nanobot plugins list      # verify the channel package appears as "webhook"
+nanobot onboard           # add default config for detected channels
+```
+
+Edit `~/.nanobot/config.json`:
+
+```json
+{
+  "channels": {
+    "webhook": {
+      "enabled": true,
+      "port": 9000,
+      "allowFrom": ["*"]
+    }
+  }
+}
+```
+
+nanobot always loads the dependency-free descriptor during discovery. When the WebUI gateway starts, it installs missing requirements for enabled channels before importing their runtimes. It also installs them when a channel is enabled from the CLI or WebUI. Status, configuration, and disable operations do not need the runtime. Single-instance and multi-instance channels use the same activation rules.
+
+### 3. Run & Test
+
+```bash
+nanobot gateway
+```
+
+In another terminal:
+
+```bash
+curl -X POST http://localhost:9000/message \
+  -H "Content-Type: application/json" \
+  -d '{"sender": "user1", "chat_id": "user1", "text": "Hello!"}'
+```
+
+The agent receives the message and processes it. Replies arrive in your `send()` method.
+
+## Channel Package Requirements
+
+Every channel is a self-contained package at `nanobot/channels/<channel>/`; channel-specific runtime code, setup metadata, tests, WebUI structure, components, and translations stay under that directory.
+
+### Package Layout
+
+```text
+nanobot/channels/<channel>/
+├── __init__.py                 # package marker only; no runtime or SDK imports

+```
+
+Do not add a runtime module directly under `nanobot/channels/`, create a parallel manifest tree, or add a central per-channel UI catalog. If existing channel files move, use `git mv` so history remains traceable.
+
+### Manifest and Runtime Boundary
+
+`manifest.py` exports a typed `ChannelPlugin` whose `runtime` target is an absolute import target, such as `nanobot.channels.telegram.runtime:TelegramChannel`; using `f"{__package__}.runtime:TelegramChannel"` keeps it package-owned without repeating the package path. Discovery imports the manifest before it knows whether the optional platform dependency is installed, so `manifest.py` must not import `runtime.py` or any platform SDK. Import runtime symbols from `runtime.py` explicitly; `__init__.py` remains an inert package marker.
+
+The manifest owns the channel name, display name, setup contract, management adapter, optional connector target, dependency requirements, capabilities, default activation, and optional WebUI entry path. The management adapter alone decides whether a channel is single-instance or multi-instance.
+
+Interactive browser setup uses one small connector contract. Set `connector=f"{__package__}.connect:MyConnectStore"`; the target is loaded only when `/api/settings/channels/<name>/connect/{start,poll,cancel}` is called. The store exposes one async `handle(action, query)` method and keeps platform-specific parsing, sessions, and errors inside the channel package. The shared settings router only authenticates, dispatches, and applies a successful connection.
+
+Use the small constructors in [`nanobot/channels/_manifest.py`](../nanobot/channels/_manifest.py) for declarative field and requirement definitions. Use [`nanobot/channels/dingtalk/manifest.py`](../nanobot/channels/dingtalk/manifest.py) as a compact single-instance example and [`nanobot/channels/feishu/`](../nanobot/channels/feishu/) as a multi-instance example.
+
+### Package-owned WebUI
+
+Set `webui="webui/index.ts"` or `webui="webui/index.tsx"` in the channel manifest. Candidate modules are bundled from channel packages, but the settings UI activates only the exact path returned by the backend feature payload.
+
+The entry module exports one default `ChannelUiContribution`. Channel identity comes from the package directory, so do not repeat a `channel` field in TypeScript. Keep only structure and executable UI data in this module: presentation metadata, icons or logo URLs, docs URLs, config field keys, action payloads, preset values, aliases, and optional `Panel` or `ConnectFlow` components.
+
+Do not put static descriptions, setup steps, labels, placeholders, help text, action labels, or preset labels in TSX. Those strings belong in the channel's locale JSON. TSX remains appropriate for dynamic rendering, interpolation, conditions, and rich component composition.
+
+### Channel-owned i18n
+
+Create `webui/locales/<locale>.json` for every locale code declared in [`webui/src/i18n/config.ts`](../webui/src/i18n/config.ts). Treat `en.json` as the canonical shape; every other locale must contain the same message keys and the same interpolation variables. `displayName` may be omitted when the product name should remain unchanged.
+
+```json
+{
+  "description": "Use nanobot from Example chats.",
+  "requirements": "Example app credentials and gateway",
+  "setup": {
+    "docsLabel": "Open Example setup",
+    "officialLabel": "Open Example console",
+    "summary": "Example needs app credentials.",
+    "tryIt": "Send a test message.",
+    "steps": [
+      "Create an Example app.",
+      "Add the credentials.",
+      "Save, enable, and test the channel."
+    ],
+    "fields": {
+      "clientId": {
+        "label": "Client ID",
+        "placeholder": "Example client ID",
+        "help": "Copy it from the Example console."
+      }
+    },
+    "actions": {
+      "copyManifest": "Copy manifest"
+    },
+    "presets": {
+      "default": "Default"
+    }
+  },
+  "custom": {
+    "connected": "{{name}} is connected."
+  }
+}
+```
+
+Field messages are keyed by the config path after `channels.<channel>.`, with remaining punctuation converted to underscores. For example, `channels.signal.dm.allowFrom` maps to `setup.fields.dm_allowFrom`. Action and preset messages use the IDs declared in the TypeScript contribution.
+
+Custom channel components should read dynamic copy with `channelTranslator(t, "<channel>")`; keep the English fallback adjacent to the call so an incomplete translation still renders useful text. Aliases reuse the owning channel's locale namespace rather than duplicating translations.
+
+The dependency direction is intentional:
+
+- [`webui/src/i18n/index.ts`](../webui/src/i18n/index.ts) imports the pure JSON [`channel-plugins/locale-registry.ts`](../webui/src/channel-plugins/locale-registry.ts).
+- The locale registry discovers only `nanobot/channels/*/webui/locales/*.json` and must not import the UI registry, React, or TSX.
+- Settings components may consume both the UI registry and locale registry.
+- Channel UI code may use shared types and generic settings components, but core settings code must not add `if (feature.name === "...")` branches for individual channels.
+
+This separation prevents i18n initialization from eagerly loading every channel React component and keeps channel-specific ownership below the channel package.
+
+### Tests and Definition of Done
+
+Put channel-specific Python tests in `nanobot/channels/<channel>/tests/`. Keep only shared registry, manager, base-class, and cross-channel contract tests in `tests/channels/`. Release builds exclude package-local tests while the repository test configuration discovers both trees.
+
+For a focused channel change, run the smallest relevant set:
+
+```bash
+uv run pytest nanobot/channels/<channel>/tests -q
+
+cd webui
+bun run test -- src/tests/channel-locale-registry.test.ts src/tests/channel-ui-registry.test.ts src/tests/channel-identity.test.ts
+bun run lint
+bun run build
+```
+
+Before considering the change complete, verify all of the following:
+
+- The manifest can be discovered without importing the runtime or optional platform SDK.
+- `ChannelSetupSpec` contains every writable field and rejects unknown fields.
+- The TypeScript field, action, and preset IDs have matching English locale messages.
+- Every supported locale matches the English key shape and interpolation variables.
+- Generic settings copy remains in core `common.json`; channel-specific copy remains inside the channel package.
+- User-facing WebUI changes work through the built frontend served by a real gateway, including language switching and refresh persistence.
+- Markdown prose paragraphs and individual list items remain on one source line; let the renderer handle visual wrapping.
+
+## BaseChannel API
+
+### Required (abstract)
+
+| Method | Description |
+|--------|-------------|
+| `async start()` | **Must block forever.** Connect to platform, listen for messages, call `_handle_message()` on each. If this returns, the channel is dead. |
+| `async stop()` | Set `self._running = False` and clean up. Called when gateway shuts down. |
+| `async send(msg: OutboundMessage)` | Deliver an outbound message to the platform. Raise when the transport does not accept it. |
+
+#### Outbound delivery contract
+
+A normal return from `send()` means either the visible payload was accepted by the platform transport/API, or the channel deliberately had nothing to deliver, such as an empty progress event. Do not log and return when the client is disconnected, still starting, or the platform rejects the request. Raise an exception so `ChannelManager` can apply the shared retry policy.
+
+`send()` may run as soon as `is_running` becomes true. If a channel sets `_running` before its transport is ready, it must keep raising until delivery can be attempted safely. Small platform-specific retries are fine, but the final failure must still reach the manager.
+
+### Interactive Login
+
+If your channel requires interactive authentication (e.g. QR code scan), override `login(force=False)`:
+
+```python
+async def login(self, force: bool = False) -> bool:
+    """
+    Perform channel-specific interactive login.
+
+    Args:
+        force: If True, ignore existing credentials and re-authenticate.
+
+    Returns True if already authenticated or login succeeds.
+    """
+    # For QR-code-based login:
+    # 1. If force, clear saved credentials
+    # 2. Check if already authenticated (load from disk/state)
+    # 3. If not, show QR code and poll for confirmation
+    # 4. Save token on success
+```
+
+Channels that don't need interactive login (e.g. Telegram with bot token, Discord with bot token) inherit the default `login()` which just returns `True`.
+
+Users trigger interactive login via:
+```bash
+nanobot channels login <channel_name>
+nanobot channels login <channel_name> --force  # re-authenticate
+```
+
+### Provided by Base
+
+| Method / Property | Description |
+|-------------------|-------------|
+| `_handle_message(sender_id, chat_id, content, media?, metadata?, session_key?)` | **Call this when you receive a message.** Checks `is_allowed()`, then publishes to the bus. Automatically sets `_wants_stream` if `supports_streaming` is true. |
+| `is_allowed(sender_id)` | Checks against `config.allow_from`; `"*"` allows all, `[]` denies all. |
+| `default_config()` (classmethod) | Returns runtime-local defaults for callers that construct the class directly. Discovery and onboarding use the descriptor instead. |
+| `refresh_feature_metadata(config_path, instance_id)` (classmethod) | Optionally refreshes saved display metadata after an explicit settings action. It is never called by a read-only feature GET. |
+| `transcribe_audio(file_path)` | Transcribes audio via the shared top-level `transcription` config (if configured). |
+| `supports_streaming` (property) | `True` when config has `"streaming": true` **and** subclass overrides `send_delta()`. |
+| `is_running` | Returns `self._running`. |
+| `login(force=False)` | Perform interactive login (e.g. QR code scan). Returns `True` if already authenticated or login succeeds. Override in subclasses that support interactive login. |
+| `send_reasoning_delta(chat_id, delta, metadata?, *, stream_id?)` | Optional hook for streamed model reasoning/thinking content. Default is no-op. |
+| `send_reasoning_end(chat_id, metadata?, *, stream_id?)` | Optional hook marking the end of a reasoning block. Default is no-op. |
+| `send_reasoning(msg)` | Optional one-shot reasoning fallback. Default translates to `send_reasoning_delta()` + `send_reasoning_end()`. |
+
+### Optional management contract
+
+Persisted-state management belongs to `ChannelPlugin.management`, not `BaseChannel`. Keep the adapter and anything it imports free of optional platform SDKs so status, settings, and disable operations still work when the runtime cannot be imported. Runtime classes own network lifecycle, message delivery, interactive login, enable-time availability checks, and explicit runtime-only actions such as metadata refresh.
+
+```python
+from nanobot.channels.contracts import ChannelFieldSpec, ChannelSetupSpec, SetupRequirement
+from nanobot.channels.plugin import ChannelPlugin
+
+from .instances import MANAGEMENT
+
+PLUGIN = ChannelPlugin(
+    name="webhook",
+    display_name="Webhook",
+    runtime=f"{__package__}.channel:WebhookChannel",
+    setup=ChannelSetupSpec(
+        fields={
+            "token": ChannelFieldSpec(kind="secret"),
+            "region": ChannelFieldSpec(
+                kind="enum",
+                choices=frozenset({"us", "eu"}),
+                default="us",
+            ),
+        },
+        required=(SetupRequirement.field("token"),),
+    ),
+    management=MANAGEMENT,
+)
+```
+
+`instances.py` then exports the dependency-free adapter assembled from channel-owned callbacks:
+
+```python
+from typing import Any
+
+from nanobot.channels.contracts import ChannelInstanceSpec, ChannelManagementSpec
+
+from .config import default_config
+
+
+def instance_specs(section: Any, *, enabled_only: bool = True) -> list[ChannelInstanceSpec]:
+    ...  # Expand the persisted channel-owned envelope.
+
+
+def update_instance_config(
+    section: Any,
+    values: dict[str, Any],
+    *,
+    instance_id: str = "default",
+) -> dict[str, Any]:
+    ...  # Update one instance without discarding sibling data.
+
+
+MANAGEMENT = ChannelManagementSpec(
+    multi_instance=True,
+    default_config=default_config,
+    instance_specs=instance_specs,
+    update_instance_config=update_instance_config,
+)
+```
+
+`ChannelSetupSpec` is authoritative for writable field names, field types, choices, defaults, required setup, secret redaction, and optional backend validation. The settings API rejects fields outside this contract. A validator receives `(values, context)`; use `context.allow_local_service_access` for host network policy instead of loading global config from the channel package.
+
+The dependency-free `MANAGEMENT` value is a `ChannelManagementSpec`. Multi-instance plugins provide `instance_specs(section, enabled_only=True)` and `update_instance_config(section, values, instance_id=...)`; they may also provide `default_config`, `runtime_name`, presentation-only `feature_instances`, and `local_state_present`. Single-instance plugins normally derive onboarding defaults from `ChannelSetupSpec`; use `default_config` only when persisted defaults include fields that are not part of generic setup.
+
+Multi-instance adapters return `ChannelInstanceSpec` objects and preserve their persisted envelope when updating one instance. Their descriptor sets `ChannelManagementSpec(multi_instance=True)`. The shared contract enforces these invariants:
+
+- every `instance_id` is non-empty and unique;
+- the management adapter's `runtime_name(channel_name, instance_id)` is the single source of routing names, and every derived name is unique and is either the channel name or starts with `<channel-name>.`;
+- runtime names cannot overwrite a runtime already owned by another channel;
+- settings instance summaries are generated from `instance_specs()` and `ChannelPlugin.setup`. They contain the authoritative `enabled` and `configured` state plus secret-safe `config_values` and `configured_fields` for the generic instance editor;
+- the management adapter's `feature_instances()` may return `None` or presentation overrides containing an `id` plus `name`, `display_name`, or `avatar_url`. It cannot override runtime state or the configuration snapshot.
+
+`ChannelInstanceSpec` contains only `instance_id` and the instance config; nanobot derives its runtime name through the adapter. Single-instance plugins keep ownership of their entire config, including a field named `instances`. Only plugins whose management spec sets `multi_instance=True` opt into instance expansion.
+
+The package/config section name owns every runtime produced from that section. Class inheritance does not transfer runtime ownership to another package.
+
+Return a concrete iterable or generator from the adapter's `instance_specs()`; nanobot materializes and validates it before constructing any runtime. Raise an exception for malformed persisted data rather than silently changing instance identity. Keep network-backed metadata refresh behind the runtime's `refresh_feature_metadata()` so feature GET requests remain dependency-free and read-only.
+
+For package layout, WebUI ownership, and localization rules, see [Channel Package Requirements](#channel-package-requirements).
+
+### Optional (streaming)
+
+| Method | Description |
+|--------|-------------|
+| `async send_delta(chat_id, delta, metadata?, *, stream_id?, stream_end=False, resuming=False)` | Override to receive streaming chunks. See [Streaming Support](#streaming-support) for details. |
+
+### Message Types
+
+```python
+@dataclass
+class OutboundMessage:
+    channel: str        # your channel name
+    chat_id: str        # recipient (same value you passed to _handle_message)
+    content: str        # markdown text — convert to platform format as needed
+    media: list[str]    # local file paths to attach (images, audio, docs)
+    metadata: dict      # channel routing context, e.g. "message_id" for threading
+    event: object | None # typed runtime/UI event; usually inspect with isinstance()
+```
+
+Runtime/UI semantics live on `msg.event`. Plugin-authored outbound messages should use typed events instead of legacy metadata flags such as `_progress`, `_stream_delta`, `_stream_end`, `_reasoning_delta`, `_turn_end`, or `_goal_status`. nanobot still accepts those old flags as a compatibility bridge for existing in-process extensions, but new plugin code should not add fresh dependencies on them.
+
+## Streaming Support
+
+Channels can opt into real-time streaming — the agent sends content token-by-token instead of one final message. This is entirely optional; channels work fine without it.
+
+### How It Works
+
+When **both** conditions are met, the agent streams content through your channel:
+
+1. Config has `"streaming": true`
+2. Your subclass overrides `send_delta()`
+
+If either is missing, the agent falls back to the normal one-shot `send()` path.
+
+### Implementing `send_delta`
+
+Override `send_delta` to handle two types of calls:
+
+```python
+async def send_delta(
+    self,
+    chat_id: str,
+    delta: str,
+    metadata: dict[str, Any] | None = None,
+    *,
+    stream_id: str | None = None,
+    stream_end: bool = False,
+    resuming: bool = False,
+) -> None:
+    buffer_key = stream_id or chat_id
+    if stream_end:
+        # Streaming finished — do final formatting, cleanup, etc.
+        return
+
+    # Regular delta — append text, update the message on screen
+    # delta contains a small chunk of text (a few tokens)
+```
+
+Streaming state is passed through keyword-only arguments, not `_stream_delta` or `_stream_end` metadata flags. Use `stream_id` to key any per-stream buffers; fall back to `chat_id` when it is missing.
+
+### Example: Webhook with Streaming
+
+```python
+class WebhookChannel(BaseChannel):
+    name = "webhook"
+    display_name = "Webhook"
+
+    def __init__(self, config: Any, bus: MessageBus):
+        if isinstance(config, dict):
+            config = WebhookConfig(**config)
+        super().__init__(config, bus)
+        self._buffers: dict[str, str] = {}
+
+    async def send_delta(
+        self,
+        chat_id: str,
+        delta: str,
+        metadata: dict[str, Any] | None = None,
+        *,
+        stream_id: str | None = None,
+        stream_end: bool = False,
+        resuming: bool = False,
+    ) -> None:
+        buffer_key = stream_id or chat_id
+        if stream_end:
+            text = self._buffers.pop(buffer_key, "")
+            # Final delivery — format and send the complete message
+            await self._deliver(chat_id, text, final=True)
+            return
+
+        self._buffers.setdefault(buffer_key, "")
+        self._buffers[buffer_key] += delta
+        # Incremental update — push partial text to the client
+        await self._deliver(chat_id, self._buffers[buffer_key], final=False)
+
+    async def send(self, msg: OutboundMessage) -> None:
+        # Non-streaming path — unchanged
+        await self._deliver(msg.chat_id, msg.content, final=True)
+```
+
+### Config
+
+Enable streaming per channel:
+
+```json
+{

+      "enabled": true,
+      "streaming": true,
+      "allowFrom": ["*"]
+    }
+  }
+}
+```
+
+When `streaming` is `false` (default) or omitted, only `send()` is called — no streaming overhead.
+
+### BaseChannel Streaming API
+
+| Method / Property | Description |
+|-------------------|-------------|
+| `async send_delta(chat_id, delta, metadata?, *, stream_id?, stream_end=False, resuming=False)` | Override to handle streaming chunks. No-op by default. |
+| `supports_streaming` (property) | Returns `True` when config has `streaming: true` **and** subclass overrides `send_delta`. |
+
+## Progress, Tool Hints, and Reasoning
+
+Besides normal assistant text, nanobot can emit low-emphasis trace blocks. These are intended for UI affordances like status rows, collapsible "used tools" groups, or reasoning/thinking blocks. Platforms that do not have a good place for them can ignore them safely.
+
+### Progress and Tool Hints
+
+Progress and tool hints arrive through the normal `send(msg)` path. Check `msg.event` before rendering:
+
+```python
+from nanobot.bus.outbound_events import ProgressEvent
+
+async def send(self, msg: OutboundMessage) -> None:
+    event = msg.event
+
+    if isinstance(event, ProgressEvent) and event.tool_hint:
+        # A short tool breadcrumb, e.g. read_file("config.json")
+        await self._send_trace(msg.chat_id, msg.content, kind="tool")
+        return
+
+    if isinstance(event, ProgressEvent):
+        # Generic non-final status, e.g. "Thinking..." or "Running command..."
+        await self._send_trace(msg.chat_id, msg.content, kind="progress")
+        return
+
+    await self._send_message(msg.chat_id, msg.content, media=msg.media)
+```
+
+Tool hints are on by default. Users can disable them globally or per channel:
+
+```json
+{
+  "channels": {
+    "sendToolHints": true,
+    "webhook": {
+      "enabled": true,
+      "sendToolHints": false
+    }
+  }
+}
+```
+
+### Reasoning Blocks
+
+Reasoning is delivered through dedicated optional hooks, not `send()`. Override `send_reasoning_delta()` and `send_reasoning_end()` if your platform can show model reasoning as a subdued/collapsible block. The default implementation is a no-op, so unsupported channels simply drop reasoning content.
+
+```python
+class WebhookChannel(BaseChannel):
+    name = "webhook"
+    display_name = "Webhook"
+
+    def __init__(self, config: Any, bus: MessageBus):
+        if isinstance(config, dict):
+            config = WebhookConfig(**config)
+        super().__init__(config, bus)
+        self._reasoning_buffers: dict[str, str] = {}
+
+    async def send_reasoning_delta(
+        self,
+        chat_id: str,
+        delta: str,
+        metadata: dict[str, Any] | None = None,
+        *,
+        stream_id: str | None = None,
+    ) -> None:
+        buffer_key = stream_id or chat_id
+        self._reasoning_buffers[buffer_key] = self._reasoning_buffers.get(buffer_key, "") + delta
+        await self._update_reasoning_block(chat_id, self._reasoning_buffers[buffer_key], final=False)
+
+    async def send_reasoning_end(
+        self,
+        chat_id: str,
+        metadata: dict[str, Any] | None = None,
+        *,
+        stream_id: str | None = None,
+    ) -> None:
+        buffer_key = stream_id or chat_id
+        text = self._reasoning_buffers.pop(buffer_key, "")
+        if text:
+            await self._update_reasoning_block(chat_id, text, final=True)
+```
+
+**Reasoning arguments:**
+
+| Argument | Meaning |
+|------|---------|
+| `delta` | A reasoning/thinking chunk for `send_reasoning_delta()`. |
+| `stream_id` | Stable id for this assistant turn/segment. Use it to key buffers instead of only `chat_id`. |
+| `send_reasoning_end()` | The current reasoning block is complete. |
+
+Reasoning visibility is controlled by `showReasoning` globally or per channel:
+
+```json
+{
+  "channels": {
+    "showReasoning": true,
+    "webhook": {
+      "enabled": true,
+      "showReasoning": true
+    }
+  }
+}
+```
+
+Recommended rendering:
+
+- Render tool hints and progress as trace/status UI, not as normal assistant replies.
+- Render reasoning with lower visual emphasis and collapse it after completion when the platform supports that.
+- Keep reasoning separate from final answer text. A final answer still arrives through `send()` or `send_delta()`.
+
+## Config
+
+### Why Pydantic model is required
+
+`BaseChannel.is_allowed()` reads the permission list via `getattr(self.config, "allow_from", [])`. This works for Pydantic models where `allow_from` is a real Python attribute, but **fails silently for plain `dict`** — `dict` has no `allow_from` attribute, so `getattr` always returns the default `[]`, causing all messages to be denied.
+
+Channel runtimes use Pydantic config models by subclassing `Base` from `nanobot.config.schema`.
+
+### Pattern
+
+1. Define a Pydantic model inheriting from `nanobot.config.schema.Base`:
+
+```python
+from pydantic import Field
+from nanobot.config.schema import Base
+
+class WebhookConfig(Base):
+    """Webhook channel configuration."""
+    enabled: bool = False
+    port: int = 9000
+    allow_from: list[str] = Field(default_factory=list)
+```
+
+`Base` is configured with `alias_generator=to_camel` and `populate_by_name=True`, so JSON keys like `"allowFrom"` and `"allow_from"` are both accepted.
+
+2. Convert `dict` → model in `__init__`:
+
+```python
+from typing import Any
+from nanobot.bus.queue import MessageBus
+
+class WebhookChannel(BaseChannel):
+    def __init__(self, config: Any, bus: MessageBus):
+        if isinstance(config, dict):
+            config = WebhookConfig(**config)
+        super().__init__(config, bus)
+```
+
+3. Access config as attributes (not `.get()`):
+
+```python
+async def start(self) -> None:
+    port = self.config.port
+    token = self.config.token
+```
+
+`allowFrom` is handled automatically by `_handle_message()` — you don't need to check it yourself.
+
+`nanobot onboard` reads the descriptor without importing the runtime. Put writable defaults in `ChannelSetupSpec`:
+
+```python
+setup=ChannelSetupSpec(
+    fields={
+        "port": ChannelFieldSpec(kind="int", default=9000),
+        "allowFrom": ChannelFieldSpec(kind="list"),
+    },
+)
+```
+
+String and secret fields default to `""`, list fields to `[]`, and boolean fields to `false` when no explicit default is declared. For non-setup or multi-instance persisted defaults, provide `ChannelManagementSpec.default_config` from a dependency-free package-local module.
+
+## Naming Convention
+
+| What | Format | Example |
+|------|--------|---------|
+| Package directory | `nanobot/channels/{name}` | `nanobot/channels/webhook` |
+| Manifest name | `{name}` | `webhook` |
+| Config section | `channels.{name}` | `channels.webhook` |
+| Runtime import | `nanobot.channels.{name}.runtime` | `nanobot.channels.webhook.runtime` |
+
+## Local Development
+
+```bash
+git clone https://github.com/HKUDS/nanobot.git
+cd nanobot
+python -m pip install -e .
+nanobot plugins list    # should show the package as "webhook"
+nanobot plugins enable webhook
+nanobot gateway         # test end-to-end
+```
+
+## Verify
+
+```bash
+$ nanobot plugins list
+
+  Name       Type      Enabled
+  discord    channel   no
+  telegram   channel   yes
+  webhook    channel   yes
+```

-# Channel Plugin Guide
-
-Build a custom nanobot channel in three steps: subclass, package, install.
-
-> **Note:** We recommend developing channel plugins against a source checkout of nanobot (`python -m pip install -e .`) rather than a PyPI release, so you always have access to the latest base-channel features and APIs.
-
-## How It Works
-
-nanobot discovers channel plugins via Python [entry points](https://packaging.python.org/en/latest/specifications/entry-points/). When `nanobot gateway` starts, it scans:
-
-1. Built-in channels in `nanobot/channels/`
-2. External packages registered under the `nanobot.channels` entry point group
-
-If a matching config section has `"enabled": true`, the channel is instantiated and started.
-
-## Quick Start
-
-We'll build a minimal webhook channel that receives messages via HTTP POST and sends replies back.
-
-### Project Structure

-
-### 2. Register the Entry Point
-
-```toml
-# pyproject.toml
-[project]
-name = "nanobot-channel-webhook"
-version = "0.1.0"
-dependencies = ["nanobot-ai", "aiohttp"]
-
-[project.entry-points."nanobot.channels"]
-webhook = "nanobot_channel_webhook:WebhookChannel"
-
-[build-system]
-requires = ["hatchling"]
-build-backend = "hatchling.build"
-
-[tool.hatch.build.targets.wheel]
-packages = ["nanobot_channel_webhook"]
-```
-
-The key (`webhook`) becomes the config section name. The value points to your `BaseChannel` subclass.
-
-### 3. Install & Configure
-
-```bash
-python -m pip install -e .
-nanobot plugins list      # verify the installed example plugin appears as "webhook"
-nanobot onboard           # auto-adds default config for detected plugins
-```
-
-Edit `~/.nanobot/config.json`:
-
-```json
-{
-  "channels": {
-    "webhook": {
-      "enabled": true,
-      "port": 9000,
-      "allowFrom": ["*"]
-    }
-  }
-}
-```
-
-### 4. Run & Test
-
-```bash
-nanobot gateway
-```
-
-In another terminal:
-
-```bash
-curl -X POST http://localhost:9000/message \
-  -H "Content-Type: application/json" \
-  -d '{"sender": "user1", "chat_id": "user1", "text": "Hello!"}'
-```
-
-The agent receives the message and processes it. Replies arrive in your `send()` method.
-
-## BaseChannel API
-
-### Required (abstract)
-
-| Method | Description |
-|--------|-------------|
-| `async start()` | **Must block forever.** Connect to platform, listen for messages, call `_handle_message()` on each. If this returns, the channel is dead. |
-| `async stop()` | Set `self._running = False` and clean up. Called when gateway shuts down. |
-| `async send(msg: OutboundMessage)` | Deliver an outbound message to the platform. |
-
-### Interactive Login
-
-If your channel requires interactive authentication (e.g. QR code scan), override `login(force=False)`:
-
-```python
-async def login(self, force: bool = False) -> bool:
-    """
-    Perform channel-specific interactive login.
-
-    Args:
-        force: If True, ignore existing credentials and re-authenticate.
-
-    Returns True if already authenticated or login succeeds.
-    """
-    # For QR-code-based login:
-    # 1. If force, clear saved credentials
-    # 2. Check if already authenticated (load from disk/state)
-    # 3. If not, show QR code and poll for confirmation
-    # 4. Save token on success
-```
-
-Channels that don't need interactive login (e.g. Telegram with bot token, Discord with bot token) inherit the default `login()` which just returns `True`.
-
-Users trigger interactive login via:
-```bash
-nanobot channels login <channel_name>
-nanobot channels login <channel_name> --force  # re-authenticate
-```
-
-### Provided by Base
-
-| Method / Property | Description |
-|-------------------|-------------|
-| `_handle_message(sender_id, chat_id, content, media?, metadata?, session_key?)` | **Call this when you receive a message.** Checks `is_allowed()`, then publishes to the bus. Automatically sets `_wants_stream` if `supports_streaming` is true. |
-| `is_allowed(sender_id)` | Checks against `config.allow_from`; `"*"` allows all, `[]` denies all. |
-| `default_config()` (classmethod) | Returns default config dict for `nanobot onboard`. Override to declare your fields. |
-| `transcribe_audio(file_path)` | Transcribes audio via the shared top-level `transcription` config (if configured). |
-| `supports_streaming` (property) | `True` when config has `"streaming": true` **and** subclass overrides `send_delta()`. |
-| `is_running` | Returns `self._running`. |
-| `login(force=False)` | Perform interactive login (e.g. QR code scan). Returns `True` if already authenticated or login succeeds. Override in subclasses that support interactive login. |
-| `send_reasoning_delta(chat_id, delta, metadata?, *, stream_id?)` | Optional hook for streamed model reasoning/thinking content. Default is no-op. |
-| `send_reasoning_end(chat_id, metadata?, *, stream_id?)` | Optional hook marking the end of a reasoning block. Default is no-op. |
-| `send_reasoning(msg)` | Optional one-shot reasoning fallback. Default translates to `send_reasoning_delta()` + `send_reasoning_end()`. |
-
-### Optional (streaming)
-
-| Method | Description |
-|--------|-------------|
-| `async send_delta(chat_id, delta, metadata?, *, stream_id?, stream_end=False, resuming=False)` | Override to receive streaming chunks. See [Streaming Support](#streaming-support) for details. |
-
-### Message Types
-
-```python
-@dataclass
-class OutboundMessage:
-    channel: str        # your channel name
-    chat_id: str        # recipient (same value you passed to _handle_message)
-    content: str        # markdown text — convert to platform format as needed
-    media: list[str]    # local file paths to attach (images, audio, docs)
-    metadata: dict      # channel routing context, e.g. "message_id" for threading
-    event: object | None # typed runtime/UI event; usually inspect with isinstance()
-```
-
-Runtime/UI semantics live on `msg.event`. Plugin-authored outbound messages should use typed events instead of legacy metadata flags such as `_progress`, `_stream_delta`, `_stream_end`, `_reasoning_delta`, `_turn_end`, or `_goal_status`. nanobot still accepts those old flags as a compatibility bridge for existing in-process extensions, but new plugin code should not add fresh dependencies on them.
-
-## Streaming Support
-
-Channels can opt into real-time streaming — the agent sends content token-by-token instead of one final message. This is entirely optional; channels work fine without it.
-
-### How It Works
-
-When **both** conditions are met, the agent streams content through your channel:
-
-1. Config has `"streaming": true`
-2. Your subclass overrides `send_delta()`
-
-If either is missing, the agent falls back to the normal one-shot `send()` path.
-
-### Implementing `send_delta`
-
-Override `send_delta` to handle two types of calls:
-
-```python
-async def send_delta(
-    self,
-    chat_id: str,
-    delta: str,
-    metadata: dict[str, Any] | None = None,
-    *,
-    stream_id: str | None = None,
-    stream_end: bool = False,
-    resuming: bool = False,
-) -> None:
-    buffer_key = stream_id or chat_id
-    if stream_end:
-        # Streaming finished — do final formatting, cleanup, etc.
-        return
-
-    # Regular delta — append text, update the message on screen
-    # delta contains a small chunk of text (a few tokens)
-```
-
-Streaming state is passed through keyword-only arguments, not `_stream_delta` or `_stream_end` metadata flags. Use `stream_id` to key any per-stream buffers; fall back to `chat_id` when it is missing.
-
-### Example: Webhook with Streaming
-
-```python
-class WebhookChannel(BaseChannel):
-    name = "webhook"
-    display_name = "Webhook"
-
-    def __init__(self, config: Any, bus: MessageBus):
-        if isinstance(config, dict):
-            config = WebhookConfig(**config)
-        super().__init__(config, bus)
-        self._buffers: dict[str, str] = {}
-
-    async def send_delta(
-        self,
-        chat_id: str,
-        delta: str,
-        metadata: dict[str, Any] | None = None,
-        *,
-        stream_id: str | None = None,
-        stream_end: bool = False,
-        resuming: bool = False,
-    ) -> None:
-        buffer_key = stream_id or chat_id
-        if stream_end:
-            text = self._buffers.pop(buffer_key, "")
-            # Final delivery — format and send the complete message
-            await self._deliver(chat_id, text, final=True)
-            return
-
-        self._buffers.setdefault(buffer_key, "")
-        self._buffers[buffer_key] += delta
-        # Incremental update — push partial text to the client
-        await self._deliver(chat_id, self._buffers[buffer_key], final=False)
-
-    async def send(self, msg: OutboundMessage) -> None:
-        # Non-streaming path — unchanged
-        await self._deliver(msg.chat_id, msg.content, final=True)
-```
-
-### Config
-
-Enable streaming per channel:
-
-```json
-{
-  "channels": {
-    "webhook": {
-      "enabled": true,
-      "streaming": true,
-      "allowFrom": ["*"]
-    }
-  }
-}
-```
-
-When `streaming` is `false` (default) or omitted, only `send()` is called — no streaming overhead.
-
-### BaseChannel Streaming API
-
-| Method / Property | Description |
-|-------------------|-------------|
-| `async send_delta(chat_id, delta, metadata?, *, stream_id?, stream_end=False, resuming=False)` | Override to handle streaming chunks. No-op by default. |
-| `supports_streaming` (property) | Returns `True` when config has `streaming: true` **and** subclass overrides `send_delta`. |
-
-## Progress, Tool Hints, and Reasoning
-
-Besides normal assistant text, nanobot can emit low-emphasis trace blocks. These are intended for UI affordances like status rows, collapsible "used tools" groups, or reasoning/thinking blocks. Platforms that do not have a good place for them can ignore them safely.
-
-### Progress and Tool Hints
-
-Progress and tool hints arrive through the normal `send(msg)` path. Check `msg.event` before rendering:
-
-```python
-from nanobot.bus.outbound_events import ProgressEvent
-
-async def send(self, msg: OutboundMessage) -> None:
-    event = msg.event
-
-    if isinstance(event, ProgressEvent) and event.tool_hint:
-        # A short tool breadcrumb, e.g. read_file("config.json")
-        await self._send_trace(msg.chat_id, msg.content, kind="tool")
-        return
-
-    if isinstance(event, ProgressEvent):
-        # Generic non-final status, e.g. "Thinking..." or "Running command..."
-        await self._send_trace(msg.chat_id, msg.content, kind="progress")
-        return
-
-    await self._send_message(msg.chat_id, msg.content, media=msg.media)
-```
-
-Tool hints are off by default for most channels. Users can enable them globally or per channel:
-
-```json
-{
-  "channels": {
-    "sendToolHints": true,
-    "webhook": {
-      "enabled": true,
-      "sendToolHints": true
-    }
-  }
-}
-```
-
-### Reasoning Blocks
-
-Reasoning is delivered through dedicated optional hooks, not `send()`. Override `send_reasoning_delta()` and `send_reasoning_end()` if your platform can show model reasoning as a subdued/collapsible block. The default implementation is a no-op, so unsupported channels simply drop reasoning content.
-
-```python
-class WebhookChannel(BaseChannel):
-    name = "webhook"
-    display_name = "Webhook"
-
-    def __init__(self, config: Any, bus: MessageBus):

-            config = WebhookConfig(**config)
-        super().__init__(config, bus)
-        self._reasoning_buffers: dict[str, str] = {}

-        await self._update_reasoning_block(chat_id, self._reasoning_buffers[buffer_key], final=False)

-        if text:
-            await self._update_reasoning_block(chat_id, text, final=True)

-
-**Reasoning arguments:**
-
-| Argument | Meaning |
-|------|---------|
-| `delta` | A reasoning/thinking chunk for `send_reasoning_delta()`. |
-| `stream_id` | Stable id for this assistant turn/segment. Use it to key buffers instead of only `chat_id`. |
-| `send_reasoning_end()` | The current reasoning block is complete. |
-
-Reasoning visibility is controlled by `showReasoning` globally or per channel:
-
-```json
-{
-  "channels": {
-    "showReasoning": true,
-    "webhook": {
-      "enabled": true,
-      "showReasoning": true
-    }
-  }
-}
-```
-
-Recommended rendering:
-
-- Render tool hints and progress as trace/status UI, not as normal assistant replies.
-- Render reasoning with lower visual emphasis and collapse it after completion when the platform supports that.
-- Keep reasoning separate from final answer text. A final answer still arrives through `send()` or `send_delta()`.

-## Config
-
-### Why Pydantic model is required
-
-`BaseChannel.is_allowed()` reads the permission list via `getattr(self.config, "allow_from", [])`. This works for Pydantic models where `allow_from` is a real Python attribute, but **fails silently for plain `dict`** — `dict` has no `allow_from` attribute, so `getattr` always returns the default `[]`, causing all messages to be denied.
-
-Built-in channels use Pydantic config models (subclassing `Base` from `nanobot.config.schema`). Plugin channels **must do the same**.
-
-### Pattern
-
-1. Define a Pydantic model inheriting from `nanobot.config.schema.Base`:
-
-```python
-from pydantic import Field
-from nanobot.config.schema import Base
-
-class WebhookConfig(Base):
-    """Webhook channel configuration."""
-    enabled: bool = False
-    port: int = 9000
-    allow_from: list[str] = Field(default_factory=list)
-```
-
-`Base` is configured with `alias_generator=to_camel` and `populate_by_name=True`, so JSON keys like `"allowFrom"` and `"allow_from"` are both accepted.
-
-2. Convert `dict` → model in `__init__`:
-
-```python
-from typing import Any
-from nanobot.bus.queue import MessageBus
-
-class WebhookChannel(BaseChannel):
-    def __init__(self, config: Any, bus: MessageBus):
-        if isinstance(config, dict):
-            config = WebhookConfig(**config)
-        super().__init__(config, bus)
-```
-
-3. Access config as attributes (not `.get()`):
-
-```python
-async def start(self) -> None:
-    port = self.config.port
-    token = self.config.token
-```
-
-`allowFrom` is handled automatically by `_handle_message()` — you don't need to check it yourself.
-
-Override `default_config()` so `nanobot onboard` auto-populates `config.json`:
-
-```python
-@classmethod
-def default_config(cls) -> dict[str, Any]:
-    return WebhookConfig().model_dump(by_alias=True)
-```
-
-> **Note:** `default_config()` returns a plain `dict` (not a Pydantic model) because it's used to serialize into `config.json`. The recommended way is to instantiate your config model and call `model_dump(by_alias=True)` — this automatically uses camelCase keys (`allowFrom`) and keeps defaults in a single source of truth.
-
-If not overridden, the base class returns `{"enabled": false}`.
-
-## Naming Convention
-
-| What | Format | Example |
-|------|--------|---------|
-| PyPI package | `nanobot-channel-{name}` | `nanobot-channel-webhook` |
-| Entry point key | `{name}` | `webhook` |
-| Config section | `channels.{name}` | `channels.webhook` |
-| Python package | `nanobot_channel_{name}` | `nanobot_channel_webhook` |

+Run nanobot online without managing a server. The blueprint deploys the gateway and bundled WebUI together, with a persistent disk so sessions, memory, and chat history survive restarts.

+> [!IMPORTANT]
+> This setup requires a paid Render service because persistent disks are not available on the free tier. During setup, provide `ANTHROPIC_API_KEY` and set `NANOBOT_WEB_TOKEN` to a strong private password (for example, generate one with `openssl rand -hex 32`).

+
+[Review the deployment blueprint](../render.yaml)
+
+### First Deployment
+
+1. Click **Deploy to Render**, sign in, and review the Blueprint. It creates one Starter web service and a 1 GB persistent disk.
+2. Enter your `ANTHROPIC_API_KEY`. Set `NANOBOT_WEB_TOKEN` to a new random value and save it in your password manager; this is the password for the public WebUI.
+3. Create the Blueprint and wait for the service status to become **Live**. The first build can take several minutes.
+4. Open the generated `onrender.com` URL. The **Authentication required** page means the gateway is running: enter the same `NANOBOT_WEB_TOKEN` value to open the WebUI.
+
+The model API key is used by nanobot to call Anthropic. The Web token only protects access to this deployment; do not share it in issues, screenshots, or chat.
+
+### Updates and Data
+
+The Blueprint disables automatic deploys so upstream repository changes do not unexpectedly restart your agent. To update, open the service in the Render Dashboard and choose **Manual Deploy → Deploy latest commit**.
+
+The persistent disk keeps `config.json`, sessions, memory, WebUI history, cron state, media, and logs across restarts and updates. The deployment initializes `config.json` only when it does not already exist, so settings changed later in the WebUI are not replaced on every boot.
+
+If deployment fails, open the service **Logs** page first. A missing model key fails provider requests after startup, while an incorrect Web token leaves you on the authentication page.

+### Cloudflare Tunnel + Cloudflare Access
+
+For a local `cloudflared` process in front of nanobot, Cloudflare Access can
+authenticate the user before forwarding the request and add
+`Cf-Access-Jwt-Assertion`. Opt in to trusted-proxy no-token mode only when the
+direct TCP peer is the tunnel process and the assertion is non-empty:
+
+```json
+{
+  "gateway": { "host": "127.0.0.1" },
+  "channels": {
+    "websocket": {
+      "host": "127.0.0.1",
+      "port": 8765,
+      "publicWsUrl": "wss://nanobot.example.com/",
+      "trustedProxyAuth": {
+        "trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
+        "assertionHeader": "Cf-Access-Jwt-Assertion"
+      }
+    }
+  }
+}
+```
+
+This is two-part authorization: a trusted direct loopback peer **and** a
+non-empty Cloudflare Access assertion. A trusted CIDR alone is not a bypass.
+For this flow `/webui/bootstrap` returns connection metadata without a
+bootstrap token or REST API token; the proxy assertion authorizes the WebSocket
+handshake and REST requests directly.
+
+Set `publicWsUrl` to the browser-facing `wss://` endpoint when the tunnel sends
+the origin host header (such as `127.0.0.1:8765`); otherwise the WebUI could
+attempt to open its WebSocket directly against the loopback address.
+The assertion header must be generated
+by Cloudflare Access after authentication; routing/client metadata headers such
+as `Host`, `Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP`
+are rejected as `assertionHeader` values. Nanobot trusts the assertion but does
+not cryptographically validate the JWT, so configure the tunnel and Access
+policy carefully and do not expose the nanobot listener directly to untrusted
+clients. Forwarded client headers do not establish proxy trust.
+
 ### Docker Compose
 
+The default image preinstalls WhatsApp dependencies. To bake other enabled
+channels into an image (recommended for deployments without PyPI access), pass
+a comma-separated `NANOBOT_CHANNELS` build argument:
+
+```bash
+NANOBOT_CHANNELS=telegram,slack docker compose build
+```
+
+The image keeps nanobot in a virtual environment owned by its built-in non-root
+runtime user (UID 1000). If an enabled channel was not preinstalled, gateway
+startup can therefore install its manifest-declared dependencies. Rebuilding
+with `NANOBOT_CHANNELS` keeps that installation reproducible instead of relying
+on the container's writable layer. If you override the container with a
+different `--user`, bake every enabled channel into the image because that UID
+is not guaranteed write access to the virtual environment.

+The default Compose file drops all Linux capabilities and keeps Docker's default

+# How to Improve Ollama Tool-Calling Prompt Cache Reuse in nanobot
+
+Some Ollama model templates move or remove tool definitions as a conversation
+switches between user, assistant, and tool messages. nanobot can send a correct
+append-only chat request while the model template still renders a different token
+prefix. On slower local hardware, re-evaluating that prefix can add tens of seconds
+to an otherwise simple tool-using turn.
+
+This guide shows how to diagnose that specific pattern and create a derived
+`llama3.1:8b` tag with a prefix-stable tool template. It does not modify nanobot or
+overwrite the original Ollama model.
+
+## What you will build
+
+- a repeatable two-turn cache check
+- an optional derived `llama3.1:8b-prefix-stable-v1` Ollama tag
+- a nanobot model preset that uses the derived tag
+
+## When to use this
+
+Use this guide when all of the following are true:
+
+- direct Ollama responses are reasonably fast;
+- nanobot becomes slow after the model calls a tool;
+- Ollama logs show a long main prompt, a much shorter tool follow-up, and low
+  initial cache reuse on the next main prompt;
+- the model is `llama3.1:8b` with a template that renders concrete tools only for
+  the final user message.
+
+Do not apply this template to another model family without checking that model's
+tool-call format first.
+
+## Diagnose the rendered prompt
+
+Stop any existing Ollama process, then start a single-slot debug server. A single
+slot makes the cache sequence easier to read.
+
+**macOS or Linux**
+
+```bash
+OLLAMA_CONTEXT_LENGTH=16384 \
+OLLAMA_NUM_PARALLEL=1 \
+OLLAMA_DEBUG=1 \
+ollama serve
+```
+
+**Windows PowerShell**
+
+```powershell
+$env:OLLAMA_CONTEXT_LENGTH = "16384"
+$env:OLLAMA_NUM_PARALLEL = "1"
+$env:OLLAMA_DEBUG = "1"
+ollama serve
+```
+
+In another terminal, use a fresh session and explicitly request a tool so both
+turns exercise the agent loop:
+
+```bash
+nanobot agent --session cli:ollama-cache-check \
+  --message "Use the exec tool to calculate 2+2, then answer"
+nanobot agent --session cli:ollama-cache-check \
+  --message "Use the exec tool to calculate 4+7, then answer"
+```
+
+In the Ollama output, find each `new prompt` line and the first
+`cached n_tokens` line that follows it. Later increasing `cached n_tokens` lines
+are prompt-evaluation progress, not additional initial cache hits.
+
+A cache-unfriendly tool template may produce a pattern like this:
+
+```text
+turn 1 main:             2 / 8460 initially cached
+turn 1 tool follow-up: 3713 / 3758 initially cached
+turn 2 main:          3767 / 8519 initially cached
+```
+
+The cache is working, but the next main request can reuse only the shorter prompt.
+Hardware throughput determines how expensive the remaining evaluation is.
+
+To inspect the API request bodies as well, add
+`OLLAMA_DEBUG_LOG_REQUESTS=1` before starting Ollama. These logs can contain system
+prompts, workspace context, and user messages. Keep them local and disable request
+logging after diagnosis.
+
+## Why this happens with the stock template
+
+The tested `llama3.1:8b` template conditionally expands the tool definitions inside
+a user message:
+
+```gotemplate
+{{- if and $.Tools $last }}
+  ... render tool definitions ...
+{{- end }}
+```
+
+The first request ends with a user message, so the tools are rendered there. After
+nanobot appends an assistant tool call and its result, that user message is no
+longer last, so the same API request history renders without the concrete tool
+block. On the next user turn, the tools reappear at a new position.
+
+This is a model-template behavior. At the API boundary, nanobot continues to append
+the assistant tool call and tool result and sends the same tool definitions.
+
+## Create a prefix-stable derived model
+
+Create `PrefixStable.Modelfile` with the content below. The template keeps concrete
+tool definitions in the system block, where they remain in the same position across
+user and tool messages.
+
+```dockerfile
+FROM llama3.1:8b
+
+TEMPLATE """{{- if or .System .Tools }}<|start_header_id|>system<|end_header_id|>

+
+When you receive a tool call response, use the output to format an answer to the original user question.
+
+You are a helpful assistant with tool calling capabilities.
+
+Given the following functions, respond with a JSON function call with the proper arguments when a tool is needed.
+
+Respond in the format {"name": function name, "parameters": dictionary of argument name and its value}. Do not use variables.

+```
+
+Create the new tag:
+
+```bash
+ollama create llama3.1:8b-prefix-stable-v1 -f PrefixStable.Modelfile
+ollama list
+```
+
+Ollama reuses the existing model layers. The new tag adds a small template and
+manifest instead of copying the base weights.
+
+## Select the derived model in nanobot
+
+Merge this preset into `~/.nanobot/config.json` and select it:
+
+```json
+{
+  "providers": {
+    "ollama": {
+      "apiBase": "http://localhost:11434/v1"
+    }
+  },
+  "modelPresets": {
+    "ollamaPrefixStable": {
+      "label": "Ollama Llama 3.1 prefix-stable",
+      "provider": "ollama",
+      "model": "llama3.1:8b-prefix-stable-v1",
+      "maxTokens": 2048,
+      "contextWindowTokens": 16384,
+      "temperature": 0.1
+    }
+  },
+  "agents": {
+    "defaults": {
+      "modelPreset": "ollamaPrefixStable"
+    }
+  }
+}
+```
+
+Verify the selected model and repeat the two-turn check:
+
+```bash
+nanobot status
+nanobot agent --session cli:ollama-stable-check \
+  --message "Use the exec tool to calculate 2+2, then answer"
+nanobot agent --session cli:ollama-stable-check \
+  --message "Use the exec tool to calculate 4+7, then answer"
+```
+
+In one controlled test with Ollama 0.32.1, `llama3.1:8b`, and one slot, the second
+main request improved from `3767 / 8519` initially cached (44.22%) to
+`8505 / 8520` (99.82%). The number of re-evaluated tokens fell from 4752 to 15.
+Treat these numbers as a diagnostic example, not a performance guarantee.
+
+## Roll back
+
+Switch `agents.defaults.modelPreset` back to the original preset. When no config
+uses the derived tag, remove it with:
+
+```bash
+ollama rm llama3.1:8b-prefix-stable-v1
+```
+
+Removing the derived tag does not remove `llama3.1:8b`.
+
+## Limitations
+
+- The template above is specific to the tested `llama3.1:8b` tool-call format.
+- Ollama or the model publisher may update the stock template in a later release.
+- Validate multiple tool calls, tool errors, parallel calls, and long conversations
+  before using a custom template for unattended workloads.
+- A higher cache ratio reduces prompt evaluation, but model generation, tool
+  execution, process startup, and storage can still dominate end-to-end latency.
+- Multiple Ollama slots change cache scheduling and may produce different results.

The default base URL is `https://api-inference.modelscope.cn/v1`; override `providers.modelscope.apiBase` only if your account routes through a different host. Chat model IDs may optionally be prefixed with `modelscope/`; nanobot strips that routing prefix before sending the request.

OAuth providers are not valid automatic fallbacks. See [`troubleshooting.md`](./troubleshooting.md#provider-and-model-problems) for proxy, headless-login, model-name, and config-key errors.

+`attributes` for caller-owned routing data; nanobot keeps it separate from

+
+`on_session_turn_persisted()` invokes its callback after a non-ephemeral turn
+has been saved. The callback receives `SessionTurnPersisted` and may read the
+completed transcript through `bot.sessions`. Callbacks run in registration
+order, and async callbacks are awaited before the run continues. They are
+observational: callback exceptions are logged and suppressed so the completed
+local turn remains successful. Durable external synchronization must catch
+failures and persist retry work before the callback returns. During SDK runs,
+callbacks execute while the session is still serialized and must not re-enter
+`bot.run()` for the same session.

 # Install and Quick Start
 
-This page gets one local nanobot reply working. After that, you can add the WebUI, chat apps, local models, web search, MCP, deployment, or custom plugins.
+This guide has one goal: get a normal nanobot reply in your browser. Do not add chat apps, MCP servers, fallback models, or deployment until this path works.
 
-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.
+If terminals, Python, or API keys are unfamiliar, use the [beginner walkthrough](./start-without-technical-background.md), which explains each term and screen.
 
-## Before You Start
+These repository docs follow current `main`. The recommended installer uses the stable package, so a newly documented WebUI screen may not appear until the next release. Each advanced guide also provides a CLI or manual config path.
 
-You need:
+## What You Need
 
 - Python 3.11 or newer.
-- One LLM provider, company endpoint, subscription endpoint, or local model server you can call. The examples below use a generic OpenAI-compatible `custom` provider so the compact path does not recommend one hosted service; any supported provider works when the key, provider name, and model ID match.
-- Git only if you install from source.
-- Node.js or Bun only if you are developing the WebUI itself.
+- Access to one supported AI provider, company endpoint, or local model server.
+- The credential, endpoint URL, and model ID required by that service. Local providers such as Ollama may not require a key.
 
-> [!IMPORTANT]
-> Repository docs may describe features that are available first in source. Install from PyPI or `uv` for the stable day-to-day release; install from source when you want the newest repository behavior or plan to contribute.
+Git is only needed for a source install. The published package already contains the WebUI. A current-source install needs `bun` or `npm` so its WebUI bundle can be built.
 
-## 1. Install
+## 1. Install nanobot
 
-Pick one install method.
+The recommended installer keeps nanobot out of the system Python environment. On a fresh local desktop, it starts the WebUI when installation finishes.
 
-**One-command setup:**
+**macOS / Linux**
 
 ```bash
 curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh
 ```
 
-On Windows PowerShell:
+**Windows PowerShell**
 
 ```powershell
 irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1 | iex
 ```
 
-The default command installs or upgrades `nanobot-ai` from PyPI, then starts `nanobot onboard --wizard`. It avoids system-wide pip installs by using an active virtual environment, `uv`, `pipx`, or a managed venv under `~/.nanobot/venv`. If Quick Start finishes, go straight to [Open the WebUI](#5-open-the-webui).
+The installer chooses an active virtual environment, `uv`, `pipx`, or a managed environment under `~/.nanobot/venv`. It installs the stable PyPI release unless you explicitly pass `--dev`. At the end it prints the exact command it used to run nanobot; if `nanobot` is not on `PATH`, reuse that full command in the examples below.
 
-To preview the plan without changing your environment, pass `--dry-run`; combine it with `--dev` when you want to preview the main-branch install.
+If you prefer to inspect the scripts first, open [`install.sh`](../scripts/install.sh) or [`install.ps1`](../scripts/install.ps1).
+
+## 2. Configure Your Model
+
+Keep the installer terminal open. The browser opens the local WebUI; go to **Settings → Models** and:
+
+1. Choose the provider or endpoint that owns your credential.
+2. Enter its API key or base URL when required.
+3. Create or select a model preset using a model ID that provider can run.
+4. Save the configuration.
+
+The WebUI launcher creates or updates:
+
+| Path | Purpose |
+|---|---|
+| `~/.nanobot/config.json` | Provider, model, WebUI, channel, tool, and runtime settings |
+| `~/.nanobot/workspace/` | Sessions, memory, skills, automations, and generated files |
+
+If the installer did not open the browser, run:
 
 ```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dry-run
+nanobot webui
 ```
 
-```powershell
-& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dry-run
-```
-
-To install the current `main` branch instead, pass `--dev`:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.sh | sh -s -- --dev
-```
-
-```powershell
-& ([scriptblock]::Create((irm https://raw.githubusercontent.com/HKUDS/nanobot/main/scripts/install.ps1))) --dev
-```
-
-If `curl` or `irm` is unavailable, or GitHub raw downloads are blocked on your network, use one of the manual install methods below.
-
-If you prefer to inspect the script first, open [`../scripts/install.sh`](../scripts/install.sh) or [`../scripts/install.ps1`](../scripts/install.ps1).
-
-**Stable release with `uv`:**
-
-```bash
-uv tool install nanobot-ai
-nanobot --version
-```
-
-**Stable release with pip:**
-
-```bash
-python -m pip install nanobot-ai
-nanobot --version
-```
-
-Use pip only inside an environment you control. If pip reports `externally-managed-environment` on macOS or Linux, use the one-command installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or create a virtual environment first.
-
-**Latest source checkout:**
-
-```bash
-git clone https://github.com/HKUDS/nanobot.git
-cd nanobot
-python -m pip install -e .
-nanobot --version
-```
-
-If your shell cannot find `nanobot` after a pip install, run the module form:
-
-```bash
-python -m nanobot --version
-python -m nanobot onboard
-```
-
-On Windows, `~` in the docs means your user profile directory, for example `C:\Users\you`.
-
-The docs use `python` in commands. If your system exposes Python 3.11+ as `python3` or `py`, use that command in the same place, for example `python3 -m pip install nanobot-ai` or `py -m nanobot --version`.
-
-## 2. Initialize
-
-Skip this section if the one-command setup already started the wizard and Quick Start finished there.
-
-```bash
-nanobot onboard
-```
-
-Use the wizard if you prefer prompts instead of editing JSON by hand:
+SSH, headless, existing-config, and older-release installs retain the terminal setup path:
 
 ```bash
 nanobot onboard --wizard
 ```
 
-Initialization creates:
+## 3. Check the Setup
 
-| 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 |
+```bash
+nanobot status
+```
 
-If you already have a config, `nanobot onboard` can refresh missing default fields without overwriting your existing values. Use `nanobot onboard --refresh` to do the same refresh without an interactive prompt.
+You want:
 
-## 3. Configure a Provider
+- a check mark for **Config** and **Workspace**;
+- the model or preset you selected;
+- a configured state for the provider used by that model.
 
-Skip this section if you already configured provider and model settings in the wizard.
+Most other providers can say `not set`. This command validates local setup but does not call the model.
 
-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.
+## 4. Get the First Reply
 
-**API key:**
+If the installer-started WebUI is no longer running, run `nanobot webui` again. Leave that terminal open; the first-run WebUI is bound to localhost, so other devices on your network cannot reach it.
+
+Send:
+
+```text
+Hello!
+```
+
+Any normal assistant answer is success. It proves that nanobot can load the config, reach the selected model, use the workspace, and serve the browser UI.
+
+Leave the terminal open while using the WebUI. If you prefer a managed background process, stop the foreground process with `Ctrl+C`, then run:
+
+```bash
+nanobot gateway --background
+nanobot gateway status
+```
+
+Use `nanobot gateway logs`, `restart`, and `stop` to manage that background gateway.
+
+## Terminal-Only Check
+
+If you do not want the browser or need to isolate a WebUI problem, send one message directly:
+
+```bash
+nanobot agent -m "Hello!"
+```
+
+Then start an interactive terminal chat with:
+
+```bash
+nanobot agent
+```
+
+In interactive mode, `Enter` sends and `Alt+Enter` inserts a newline. Exit with `exit`, `/exit`, `:q`, or `Ctrl+D`.
+
+## Choose One Next Step
+
+After the first reply works, add one capability and test again:
+
+| Goal | Recommended path |
+|---|---|
+| Learn sessions, workspaces, tools, and access modes | [WebUI guide](./webui.md) |
+| Connect a chat platform | Open **Settings → Channels**, then use [Chat Apps](./chat-apps.md) for platform prerequisites |
+| Change or add a model | Open **Settings → Models**; use the [Provider Cookbook](./provider-cookbook.md) for a recipe |
+| Add web search, voice, or image generation | Use the matching WebUI Settings page, then consult [Configuration](./configuration.md) for advanced fields |
+| Add an App or MCP integration | Open **Apps** or follow [Configure MCP Tools](./guides/configure-mcp-tools.md) |
+| Schedule agent work | Read [Automations](./automations.md) |
+| Run continuously or remotely | Read [Deployment](./deployment.md) |
+| Integrate from code | Use the [Python SDK](./python-sdk.md) or [OpenAI-Compatible API](./openai-api.md) |
+
+## Other Install Methods
+
+Use one method, then continue at [Configure Your Model](#2-configure-your-model).
+
+**uv**
+
+```bash
+uv tool install nanobot-ai
+nanobot webui
+```
+
+**pip in a virtual environment**
+
+```bash
+python -m pip install nanobot-ai
+nanobot webui
+```
+
+If pip reports `externally-managed-environment`, use the recommended installer, `uv tool install nanobot-ai`, `pipx install nanobot-ai`, or create a virtual environment. Do not force a system-wide install.
+
+**Current source**
+
+`bun` or `npm` must be available. Activate a virtual environment first, then run:
+
+```bash
+git clone https://github.com/HKUDS/nanobot.git
+cd nanobot
+python -m pip install .
+nanobot webui
+```
+
+On Windows, if `python -m pip install .` reports that it cannot launch `npm`, run `cd webui`, `npm.cmd install --package-lock=false`, `npm.cmd run build`, and `cd ..` in order, then retry the install.
+
+The source path follows current `main` and can be newer than the published package. A non-editable install triggers the build hook that bundles the current WebUI. For editable Python or frontend development, follow [`../CONTRIBUTING.md`](../CONTRIBUTING.md) and [`../webui/README.md`](../webui/README.md).
+
+If the package is installed but the shell cannot find `nanobot`, use the runner that owns the installation. The recommended installer prints the exact command to reuse. Common forms are:
+
+```bash
+uv tool run --from nanobot-ai nanobot --version
+pipx run --spec nanobot-ai nanobot --version
+~/.nanobot/venv/bin/python -m nanobot --version
+```
+
+On Windows, the managed-environment form is `& "$HOME\.nanobot\venv\Scripts\python.exe" -m nanobot --version`. Replace `--version` with `webui`, `onboard --wizard`, or any other arguments you need. Use plain `python -m nanobot` only when that Python executable belongs to the environment where nanobot was installed.
+
+## Manual Configuration Fallback
+
+Use this only when the wizard is unavailable or you intentionally manage JSON. First run `nanobot onboard`, then merge a provider and a named model preset into `~/.nanobot/config.json`.
+
+A generic OpenAI-compatible setup has this shape:
 
 ```json
 {
   "providers": {
     "custom": {
-      "apiKey": "your-api-key",
+      "apiKey": "${PROVIDER_API_KEY}",

 }
 ```
 
-The provider and model inside a preset must match. The snippet above is only an example. For another provider, replace these values together:
-
-| Replace | Where |
-|---|---|
-| Provider config key, such as `custom` | `providers.<provider>` |
-| API key or environment variable | `providers.<provider>.apiKey` |
-| Preset provider name | `modelPresets.primary.provider` |
-| Model ID | `modelPresets.primary.model` |
-| Endpoint URL, only when needed | `providers.<provider>.apiBase` |
-
-Direct `agents.defaults.provider` and `agents.defaults.model` still work for existing configs, but named presets are the recommended path because they also power `/model` switching and fallback chains. For provider-specific examples across direct, gateway, OAuth, cloud, and local setups, see [`providers.md`](./providers.md).
-
-**What about `apiBase` / base URL?**
-
-`apiBase` is the HTTP base URL of the provider endpoint, not the model name. Most hosted providers in nanobot already know their default endpoint, so you usually only set `apiKey` and a model preset. Set `apiBase` when you are using:
-
-- `custom` for a third-party or self-hosted OpenAI-compatible API;
-- a local OpenAI-compatible server such as Ollama, vLLM, or LM Studio;
-- a provider-specific alternate endpoint, regional endpoint, proxy, or subscription endpoint.
-
-Examples:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "${CUSTOM_API_KEY}",
-      "apiBase": "https://api.example.com/v1"
-    }
-  }
-}
-```
-
-```json
-{
-  "providers": {
-    "ollama": {
-      "apiBase": "http://localhost:11434/v1"
-    }
-  }
-}
-```
-
-If the provider's docs say the endpoint is `/v1`, include `/v1` in `apiBase`. The model ID still belongs in the active `modelPresets` entry.
-
-If you prefer not to store secrets in `config.json`, reference an environment variable and set it before starting nanobot:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "${PROVIDER_API_KEY}",
-      "apiBase": "https://api.example.com/v1"
-    }
-  }
-}
-```
-
-## 4. Check the Setup
-
-```bash
-nanobot status
-```
-
-This should show the config path, workspace path, active model or preset, and provider summary. It does not send a message to the model, so use it as a quick config check before the first real request.
-
-Read it like this:
-
-| Status line | What you want |
-|---|---|
-| `Config` | A check mark. |
-| `Workspace` | A check mark. |
-| `Model` | The model or preset you expect. |
-| Provider list | Most providers can say `not set`; the provider used by the active preset should show a check mark, OAuth status, or local URL. |
-
-## 5. Open the WebUI
-
-Start the browser workbench:
-
-```bash
-nanobot webui
-```
-
-`nanobot webui` prepares the local WebSocket channel and WebUI bootstrap secret if needed, starts the gateway, and opens `http://127.0.0.1:8765`. First-run WebUI setup binds to `127.0.0.1` by default, so it is not exposed to your LAN. Use `nanobot webui --background` when you want the gateway to keep running without an open terminal.
-
-## 6. Test One CLI Message
-
-Use this path if you skipped Quick Start, declined the WebSocket channel, or want a terminal-only check.
-
-Run a one-shot CLI message:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-A successful first run proves that:
-
-- the `nanobot` command is installed;
-- `~/.nanobot/config.json` can be loaded;
-- the selected provider and model can answer;
-- the default workspace can be created and used.
-
-The reply text itself will vary. Any normal assistant answer means the install, config, provider, model, and workspace path are all usable.
-
-If that works, start an interactive CLI chat:
-
-```bash
-nanobot agent
-```
-
-After the interactive session can answer normally, nanobot can help with its own next setup step. Ask it to read the relevant docs, inspect your current `~/.nanobot/config.json`, and make one concrete change such as enabling WebUI, adding a provider preset, or configuring one chat channel. When nanobot says the config is updated, run `/restart` in the chat or restart the nanobot process manually so long-running processes reload `config.json`.
-
-Example prompt:
-
-```text
-Read docs/quick-start.md, docs/providers.md, and docs/configuration.md in this checkout.
-Then update ~/.nanobot/config.json to add a model preset named "primary" for my provider.
-Tell me exactly what changed and whether I need to run /restart.
-```
-
-In interactive mode, `Enter` sends the current message. Press `Alt+Enter` to add a newline before sending.
-
-Exit interactive mode with `exit`, `quit`, `/exit`, `/quit`, `:q`, or `Ctrl+D`.
-
-## 7. Choose Your Next Step

-| Want to... | Go to |
-|---|---|
-| Understand config, workspace, gateway, channels, memory, and tools | [`concepts.md`](./concepts.md) |
-| Copy another provider or local model setup | [`provider-cookbook.md`](./provider-cookbook.md) |

-**Source checkout:**
+For a source checkout:
 
 ```bash
 git pull
-python -m pip install -e .
-nanobot --version
+python -m pip install .
 ```
 
-If you use WhatsApp from a source checkout, keep the optional dependencies installed:
+Then check `nanobot --version`. Run `nanobot onboard --refresh` when you want to add newly introduced default fields while preserving existing settings.
+
+## If the First Reply Fails
+
+Do not change several settings at once. Start with:
 
 ```bash
-nanobot plugins enable whatsapp
+nanobot --version
+nanobot status
+nanobot agent -m "Hello!"
 ```
 
-## First-Run Troubleshooting
+| Symptom | First check |
+|---|---|
+| `nanobot: command not found` | Reuse the installer command or method-specific runner described under [Other Install Methods](#other-install-methods) |
+| JSON parse error | Check commas and braces; remember that docs examples are usually snippets |
+| `401` or invalid API key | Verify the selected provider owns that key and remove accidental spaces |
+| Model not found | Use a model ID available from the provider selected in the active preset |
+| CLI works but WebUI does not open | Use port `8765`, not gateway health port `18790` |
+| WebUI works but a chat app does not | Check **Settings → Channels**, then run `nanobot channels status` |
 
-| 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 | Run `nanobot webui`; the browser UI uses port `8765`, not the gateway health port `18790`. |

 # Start Without Technical Background
 
-This page is for you if you have never used a terminal, edited a JSON file, or configured an AI model before.
+This walkthrough is for people who have not used a terminal, API key, or JSON config file before. The goal is only to get one reply in a browser. You do not need to understand nanobot's architecture or edit its config by hand.
 
-The goal is small: get one local nanobot reply in your browser. Do not connect Telegram, Discord, Docker, local models, or deployment yet. Those are easier after the first reply works.
+## What You Will Need
 
-## What You Are Setting Up
+- A Windows, macOS, or Linux computer.
+- Python 3.11 or newer.
+- An account or endpoint that can run an AI model.
+- The API key, login, endpoint, and model name required by that service. A local model such as Ollama may not require an API key.
 
-You only need these words for Quick Start:
+An API key is password-like. Do not post it in an issue, screenshot, chat, or public config file.
 
-| Word | Plain meaning |
+## A Few Useful Words
+
+| Word | Meaning |
 |---|---|
-| Terminal | A text window where you paste commands and press Enter. |
-| Command | One line of text you run in the terminal. |
-| API key | A password-like token from an AI provider. Do not share it publicly. |
-| Config file | The settings file nanobot reads when it starts. |
-| Wizard | An interactive terminal menu that edits the config file for you. |
-| Browser UI | The local web page where you chat with nanobot. |
+| Terminal | A text window where you paste a command and press Enter |
+| Command | One instruction typed into the terminal |
+| Provider | The service or local server that runs the AI model |
+| Model ID | The exact model name expected by that provider |
+| API key | A secret credential that lets software call the provider |
+| Wizard | A question-and-answer setup menu |
+| WebUI | The local browser page where you use nanobot |
 
-## 1. Open a Terminal
+## 1. Install Python
 
-You will paste commands into a terminal. Copy only the command text inside each code block; do not copy the ``` marks.
+Download Python from [python.org](https://www.python.org/downloads/) if you do not already have version 3.11 or newer. On Windows, enable **Add python.exe to PATH** if the installer shows that option.
 
-| System | How to open it |
+Open a terminal:
+
+| System | How |
 |---|---|
-| 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. |
+| Windows | Press `Win`, type `PowerShell`, and open Windows PowerShell |
+| macOS | Press `Command+Space`, type `Terminal`, and press Enter |
+| Linux | Open your application menu and search for Terminal |
 
-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:
+Check Python:
 
 ```bash
 python --version
 ```
 
-If Windows says `python` is not found, close and reopen PowerShell. If it still does not work, try:
+The result should start with `Python 3.11` or a newer number. If the command is not found, close and reopen the terminal. You can also try `python3 --version` on macOS/Linux or `py --version` on Windows.
 
-```bash
-py --version
-```
+## 2. Prepare Your Model Details
 
-If `py` works but `python` does not, replace `python` with `py` in the commands below.
+nanobot does not create an AI provider account for you. Before setup, have these details nearby:
 
-If macOS or Linux says `python` is not found, try:
+1. The provider or company endpoint name.
+2. Its API key, if it requires one.
+3. Its base URL, if its documentation gives you one.
+4. A model ID your account can use.
 
-```bash
-python3 --version
-```
+The provider, credential, endpoint, and model must belong together. For example, an API key from one provider usually cannot call a model name copied from a different provider.
 
-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. Install nanobot
 
-## 3. Get a Provider API Key
-
-nanobot does not create AI accounts or API keys for you. Use an AI provider account, company endpoint, subscription endpoint, or local model server that you already control. If the provider has an OpenAI-compatible base URL in its docs, keep that nearby too.
-
-For the setup path:
-
-1. Open your provider's API key page.
-2. Create or copy an API key.
-3. Keep the key private.
-4. Keep the provider's base URL nearby if the provider docs show one.
-
-## 4. Install nanobot
-
-The easiest path is the one-command installer. It installs or upgrades nanobot, then starts the setup wizard. On macOS and Linux it avoids system-wide pip installs by using an active virtual environment, `uv`, `pipx`, or a managed venv under `~/.nanobot/venv`.
+Copy the command for your system, paste it into the terminal, and press Enter. Copy only the text inside the code block.

-These commands install the stable PyPI package. To preview what the installer would do without changing your environment, pass `--dry-run`:
+The installer downloads the stable nanobot package into an isolated Python environment. On a fresh local desktop, it then starts the WebUI and opens your browser. This can take a few minutes on the first run. Keep the terminal open. It prints the exact command used to run nanobot; if `nanobot` is not found later, reuse that whole command instead of switching to a different Python command.

+Treat every API key like a password. Do not include it in screenshots or support requests.
 
-If the command says `curl` or `irm` is not found, or it cannot download from GitHub, use one of the manual install commands below.
-
-If `uv` is installed, use:
-
-```bash
-uv tool install nanobot-ai
-```
-
-If you prefer pip, use it only inside an environment you control:
-
-```bash
-python -m pip install nanobot-ai
-```
-
-If pip reports `externally-managed-environment` on macOS or Linux, go back to the one-command installer, use `uv tool install nanobot-ai`, use `pipx install nanobot-ai`, or create a virtual environment first.
-
-Then check that nanobot is installed:
-
-```bash
-nanobot --version
-```
-
-If the terminal cannot find `nanobot`, use the module form:
-
-```bash
-python -m nanobot --version
-```
-
-Use `python3 -m nanobot --version` or `py -m nanobot --version` if that is the Python command that worked in step 2.
-
-## 5. Run the Setup Wizard
-
-The one-command installer starts this for you after installation. If you installed manually, run:
-
-```bash
-nanobot onboard --wizard
-```
-
-If `nanobot` is not found, run:
-
-```bash
-python -m nanobot onboard --wizard
-```
-
-Use `python3 -m nanobot onboard --wizard` or `py -m nanobot onboard --wizard` if that is the Python command that worked in step 2.
-
-The wizard is a terminal menu. It is not a graphical app, but it lets you choose options instead of hand-editing every JSON field.
-
-You will see a menu like this:
-
-```text
-> What would you like to do?
-  [Q] Quick Start
-  [A] Advanced Settings
-  [X] Exit
-```
-
-Move through the wizard like this:
-
-| When you see | Do this |
-|---|---|
-| A menu | Use the arrow keys to highlight an option, then press `Enter`. |
-| The provider menu | Choose the company or service you want to use. |
-| An endpoint menu | Choose the standard API or subscription plan endpoint that matches your key. |
-| An API key field | Paste the key, then press `Enter`. |
-| A provider base URL field | Paste the provider base URL from its docs, then press `Enter`. |
-| The Model ID field | Paste a model name from your provider, then press `Enter`. |
-| A back option in Advanced Settings | Choose it to return to the previous menu. |
-
-For the first setup, choose `[Q] Quick Start`. It configures the recommended local browser UI and default AI settings for you. Use `Advanced Settings` later only if you need a chat app, a tool setup, or provider-specific fields.
-
-1. Choose `[Q] Quick Start`.
-2. Choose the provider you want to use.
-3. Choose the endpoint if the wizard asks, such as Standard API, Coding Plan, Token Plan, or Step Plan.
-4. Paste your API key if the wizard asks for one.
-5. Paste the provider base URL if the wizard asks for one.
-6. Paste a model ID that provider can run.
-7. Confirm that Quick Start should configure the local WebUI.
-8. Set the WebUI password when prompted.
-9. Review the Quick Start summary. The wizard saves and exits when Quick Start finishes.
-
-The recommended path configures the local WebUI, requires a WebUI password, and writes default AI settings. You do not need to choose a separate chat app for the first run.
-
-If you already know that you need custom headers, provider-specific request fields, a chat app, or tools, choose `Advanced Settings` instead. [`provider-cookbook.md`](./provider-cookbook.md) has copyable examples for several common provider setups. After you change advanced settings, a save option appears in the main menu. Choose `[S] Save and Exit`.
-
-The wizard creates or updates:
-
-| Path | Meaning |
-|---|---|
-| `~/.nanobot/config.json` | Settings file. |
-| `~/.nanobot/workspace/` | Working folder for memory, sessions, and generated files. |
-
-If Quick Start finished successfully, skip to [Open the WebUI](#7-open-the-webui). The next two sections are only for manual setup.
-
-## Manual Setup: How to Merge JSON Snippets
-
-Most docs examples are snippets, not whole files. Your `config.json` has one outer `{ ... }`. Add new top-level sections such as `providers`, `modelPresets`, `agents`, or `channels` inside that same outer object.
-
-Do not paste two separate JSON objects into one file:
-
-```text
-{
-  "providers": { "...": "..." }
-}
-{
-  "channels": { "...": "..." }
-}
-```
-
-Merge them into one object:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "your-api-key",
-      "apiBase": "https://api.example.com/v1"
-    }
-  },
-  "channels": {
-    "websocket": {
-      "tokenIssueSecret": "your-webui-password",
-      "websocketRequiresToken": true
-    }
-  }
-}
-```
-
-Notice the comma after the `providers` block. JSON needs commas between sibling sections, but not after the last section. If this feels hard, use `nanobot onboard --wizard` whenever possible.
-
-## 6. Manual Setup: Config Fallback
-
-Use this only if the wizard is unavailable or you prefer opening the file yourself.
-
-Run `nanobot onboard` first if `~/.nanobot/config.json` does not exist yet.
-
-Use one of these commands:
-
-**Windows PowerShell**
-
-```powershell
-notepad "$env:USERPROFILE\.nanobot\config.json"
-```
-
-**macOS**
-
-```bash
-open -e ~/.nanobot/config.json
-```
-
-**Linux**
-
-```bash
-xdg-open ~/.nanobot/config.json
-```
-
-If this is a brand-new install and you have not configured anything else yet, replace the file with this minimal config:
-
-```json
-{
-  "providers": {
-    "custom": {
-      "apiKey": "your-api-key",
-      "apiBase": "https://api.example.com/v1"
-    }
-  },
-  "modelPresets": {
-    "primary": {
-      "label": "Primary",
-      "provider": "custom",
-      "model": "model-id-from-your-provider",
-      "maxTokens": 4096,
-      "contextWindowTokens": 65536,
-      "temperature": 0.1
-    }
-  },
-  "agents": {
-    "defaults": {
-      "modelPreset": "primary"
-    }
-  },
-  "channels": {
-    "websocket": {
-      "tokenIssueSecret": "your-webui-password",
-      "websocketRequiresToken": true
-    }
-  }
-}
-```
-
-Replace `your-api-key`, `https://api.example.com/v1`, `model-id-from-your-provider`, and `your-webui-password` with your own values.
-
-For copyable provider-specific examples, use [`provider-cookbook.md`](./provider-cookbook.md).
-
-Save the file.
-
-## 7. Open the WebUI
-
-First check that nanobot can read the saved setup:
-
-```bash
-nanobot status
-```
-
-This should show the config file path, workspace path, and the active model or preset. If `nanobot` is not found, use `python -m nanobot status`, `python3 -m nanobot status`, or `py -m nanobot status`, matching the Python command that worked in step 2.
-
-It is normal for most providers to say `not set`. Only the provider you selected for the active preset needs to look configured.
-
-Start the local browser UI:
+If the installer finishes without opening the browser and `nanobot` is available, run:
 
 ```bash
 nanobot webui
 ```
 
-This starts nanobot and opens `http://127.0.0.1:8765` in your browser. Leave the terminal open while you use the WebUI. Enter the WebUI password you set in the wizard if the browser asks for one.
+If the terminal cannot find `nanobot`, take the exact command printed by the installer and replace its final arguments with `webui`. That command may begin with `uv tool run`, `pipx run`, or the full path to nanobot's private Python environment.
 
-Send this first message in the browser:
+On SSH, a computer without a desktop, an existing configuration, or an older nanobot release, the installer may open the terminal wizard instead. Choose **Quick Start** there and follow its prompts.
+
+## 5. Get the First Reply
+
+Leave the WebUI terminal open. If the browser did not open automatically, visit `http://127.0.0.1:8765`.
+
+Send this message:
 
 ```text
 Hello!
 ```
 
-If that works, nanobot is installed and can call the model. You should see a normal assistant reply in the browser. The exact words will differ, but it should look like this shape:
+A normal assistant reply means setup is complete. The exact reply does not matter.
 
-```text
-Hello! How can I help you today?
-```
+The first-run address is local to your computer. It is not automatically available to other computers on your network.
 
-If `nanobot` is not found, run:
+## 6. Add One Thing at a Time
+
+Do not configure every feature immediately. Choose one next goal:
+
+| Goal | What to do |
+|---|---|
+| Change the AI model | Open **Settings → Models** |
+| Add a provider credential | Open **Settings → Models**, then find the provider |
+| Connect Telegram, Discord, Slack, Feishu, WeChat, or another chat app | Open **Settings → Channels**, choose the platform, and follow its connection steps |
+| Add a tool integration | Open **Apps** and choose an App or MCP integration |
+| Schedule a reminder or recurring task | Ask nanobot in the target chat, then manage it in **Automations** |
+| Work with project files | Start a new chat, choose the project workspace, and review the access setting before sending the task |
+
+Repository docs show the current development version. If your stable package does not yet show **Settings → Channels**, use the [Chat Apps guide](./chat-apps.md) or update to a release that includes it.
+
+Some runtime changes ask you to restart nanobot. Use the restart action shown by the WebUI, or return to the terminal, press `Ctrl+C`, and run `nanobot webui` again.
+
+For a chat platform's account, bot, token, or permission prerequisites, use the [Chat Apps guide](./chat-apps.md). For local models and provider-specific recipes, use the [Provider Cookbook](./provider-cookbook.md).
+
+## If Something Fails
+
+Run these commands one at a time:
 
 ```bash
-python -m nanobot webui
+nanobot --version
+nanobot status
+nanobot agent -m "Hello!"
 ```
 
-Use `python3 -m nanobot webui` or `py -m nanobot webui` if that is the Python command that worked in step 2.
-
-Once this works, nanobot can help with its own next setup step. In the browser UI, ask it to read these docs and update your current config for one specific goal, then run `/restart` when nanobot tells you the config is ready. For example, ask it to add one provider preset or configure one chat app.
-
-## 8. If Something Fails
-
-Do not change many things at once. Check the exact error:
-
-| Error or symptom | What it usually means |
+| What you see | What it usually means |
 |---|---|
-| `JSON parse error` | The config file has a missing comma, extra comma, or mismatched brace. Copy the example again. |
-| `401`, `unauthorized`, or `invalid API key` | The API key is wrong, expired, has extra spaces, or was pasted under the wrong provider. |
-| `model not found` | Your account cannot use the default model. Return to `nanobot onboard --wizard`, choose `Advanced Settings`, then edit `Model Presets`. |
-| `nanobot: command not found` | The install worked in Python, but your shell cannot find the script. Use `python -m nanobot ...`, `python3 -m nanobot ...`, or `py -m nanobot ...`, matching the Python command that worked earlier. |
-| No response after editing config | Restart the command. Long-running processes read config when they start. |
+| `nanobot: command not found` | Reuse the exact nanobot command printed by the installer; it points to the isolated environment that contains the package |
+| `401`, unauthorized, or invalid API key | The key is wrong, expired, or belongs to a different provider |
+| Model not found | The model ID is misspelled or unavailable to your provider account |
+| Browser does not open | Open `http://127.0.0.1:8765` yourself and keep the terminal running |
+| Browser opens but messages fail | Test `nanobot agent -m "Hello!"` to separate a model problem from a WebUI problem |
+| A change was saved but nothing changed | Restart nanobot so the running process reloads the config |
 
-For a fuller diagnosis path, see [`troubleshooting.md`](./troubleshooting.md).
+If you ask for help, include your operating system, `nanobot --version`, `nanobot status`, the exact command, and the exact error. Remove every API key, bot token, password, OAuth token, and private account ID first.
 
-## What Not to Configure Yet
+Continue with the full [Troubleshooting guide](./troubleshooting.md) for an ordered diagnosis.
 
-Skip these until the first local message works:
-
-- `apiBase`: hosted built-in providers often already have default endpoints. You only need `apiBase` for local models, proxies, custom OpenAI-compatible providers, or special regional/subscription endpoints.
-- chat apps: first prove the local browser UI can answer.
-- fallback models: useful later, but not needed for the first reply.
-- Langfuse: useful for observability, but not needed for first setup.
-
-## Next Steps
-
-After the first reply works, choose only one next goal. Keep the terminal that runs `nanobot webui` open whenever you use the WebUI. Chat apps use the same gateway service underneath.

+### Slow Optional Channel Dependency Installation
+
+Before loading enabled channels, the gateway checks the dependencies declared by their
+channel manifests. The CLI and WebUI normally install these dependencies when a channel is
+enabled. Installation during startup is a recovery path for an enabled config whose Python
+environment no longer has the required packages, for example after manually editing the
+config, upgrading nanobot, or recreating an isolated `uv tool`/`pipx` environment. The

+skip the installation once the dependencies are present.
+
+If access to PyPI is slow in your region, configure pip to use a trusted package index. The
+installer honors the standard `PIP_INDEX_URL` environment variable, including when nanobot
+itself was installed with `uv tool`:
+
+```bash
+PIP_INDEX_URL=https://your-trusted-mirror.example/simple nanobot gateway

+The embedded WebUI's `/webui/bootstrap` route returns a WebSocket token and
+REST `api_token` for local or secret-authenticated requests. When
+`trustedProxyAuth` authenticates the direct proxy peer, it returns connection
+metadata only: no bootstrap token, no REST API token, and no token query
+parameter is required for the WebSocket handshake or subsequent REST requests.
+
+### Trusted proxy no-token bootstrap
+
+`trustedProxyAuth` is an opt-in alternative for deployments where an
+identity-aware reverse proxy authenticates the user before connecting to nanobot.
+The proxy assertion becomes the authentication boundary for the entire WebUI
+surface: `/webui/bootstrap`, the WebSocket handshake, and REST API routes.
+Bootstrap is accepted only when **both** the direct TCP peer matches one of
+`trustedPeerCidrs` and the configured assertion header is present and non-empty.
+A trusted address by itself is never sufficient.
+
+Nanobot deliberately uses only `connection.remote_address` for the peer check.
+It never uses `X-Forwarded-For`, `Forwarded`, `X-Real-IP`, `CF-Connecting-IP`,
+or `X-Forwarded-Host` to decide whether the proxy is trusted. Nanobot trusts the
+assertion supplied by the explicitly trusted peer, but does not cryptographically
+validate or interpret the JWT/assertion contents. Do not enable this option if
+untrusted clients can connect directly to the nanobot listener.
+
+The configured assertion header must be a proxy-generated authentication
+assertion, not a routing or client metadata header. Headers such as `Host`,
+`Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP` are rejected
+by configuration; use the identity provider's post-authentication assertion
+header instead (for example, `Cf-Access-Jwt-Assertion`).
+
+For example, a local Cloudflare Tunnel with Cloudflare Access can validate the
+user at the edge and forward the resulting `Cf-Access-Jwt-Assertion`:
+
+```json
+{
+  "channels": {
+    "websocket": {
+      "host": "127.0.0.1",
+      "publicWsUrl": "wss://nanobot.example.com/",
+      "trustedProxyAuth": {
+        "trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
+        "assertionHeader": "Cf-Access-Jwt-Assertion"
+      }
+    }
+  }
+}
+```
+
+This works only when the directly connected `cloudflared` process reaches
+nanobot over the configured loopback address and supplies a non-empty assertion.
+Keep nanobot firewalled from untrusted clients; this configuration is not a
+CIDR-based bootstrap bypass.
