Merge remote-tracking branch 'origin/main'

Adjust the spawn tool description to keep the workspace-organizing hint while
avoiding language that sounds like the system automatically assigns a dedicated
working directory for subagents.

+# Repository Guidelines
+
+## Project Structure & Module Organization
+`nanobot/` is the main Python package. Core agent logic lives in `nanobot/agent/`, channel integrations in `nanobot/channels/`, providers in `nanobot/providers/`, and CLI/config code in `nanobot/cli/` and `nanobot/config/`. Localized command/help text lives in `nanobot/locales/`. Bundled prompts and built-in skills live in `nanobot/templates/` and `nanobot/skills/`, while workspace-installed skills are loaded from `<workspace>/skills/`. Tests go in `tests/` with `test_<feature>.py` names. The WhatsApp bridge is a separate TypeScript project in `bridge/`.
+
+## Build, Test, and Development Commands
+- `uv sync --extra dev`: install Python runtime and developer dependencies from `pyproject.toml` and `uv.lock`.
+- `uv run pytest`: run the full Python test suite.
+- `uv run pytest tests/test_web_tools.py -q`: run one focused test file during iteration.
+- `uv run pytest tests/test_skill_commands.py -q`: run the ClawHub slash-command regression tests.
+- `uv run ruff check .`: lint Python code and normalize import ordering.
+- `uv run nanobot agent`: start the local CLI agent.
+- `cd bridge && npm install && npm run build`: install and compile the WhatsApp bridge.
+- `bash tests/test_docker.sh`: smoke-test the Docker image and onboarding flow.
+
+## Coding Style & Naming Conventions
+Target Python 3.11+ and keep Python code consistent with Ruff: 4-space indentation, `snake_case` for functions/modules, `PascalCase` for classes, and `UPPER_SNAKE_CASE` for constants. Ruff uses a 100-character target; stay near it even though long-line errors are ignored. Prefer explicit type hints and small functions. In `bridge/src/`, keep the current ESM TypeScript style and avoid reformatting unrelated lines.
+
+## Testing Guidelines
+Write pytest tests using `tests/test_<feature>.py` naming. Add a regression test for every bug fix and cover async flows, channel adapters, and tool behavior when touched. If you change slash commands or command help, update the related loop/localization tests and, when relevant, Telegram command-menu coverage. `pytest-asyncio` is already enabled with automatic asyncio handling. There is no published coverage gate, so prefer targeted assertions over smoke-only tests.
+
+## Commit & Pull Request Guidelines
+Recent history favors short Conventional Commit subjects such as `fix(memory): ...`, `feat(web): ...`, and `docs: ...`. Use imperative mood, add a scope when it helps, and keep unrelated changes out of the same commit. PRs should summarize the behavior change, note config or channel impact, list the tests you ran, and link the relevant issue or PR discussion. Include screenshots only when CLI output or user-visible behavior changed.
+
+## Security & Configuration Tips
+Do not commit real API keys, tokens, chat logs, or workspace data. Keep local secrets in `~/.nanobot/config.json` and use sanitized examples in docs and tests. If you change authentication, network access, or other safety-sensitive behavior, update `README.md` or `SECURITY.md` in the same PR.
+- If a change affects user-visible behavior, commands, workflows, or contributor conventions, update both `README.md` and `AGENTS.md` in the same patch so runtime docs and repo rules stay aligned.
+
+## Chat Commands & Skills
+- Slash commands are handled in `nanobot/agent/loop.py`; keep parsing logic there instead of scattering command behavior across channels.
+- When a slash command changes user-visible wording, update both `nanobot/locales/en.json` and `nanobot/locales/zh.json`.
+- If a slash command should appear in Telegram's native command menu, also update `nanobot/channels/telegram.py`.
+- `/skill` currently supports `search`, `install`, `uninstall`, `list`, and `update`. Keep subcommand dispatch in `nanobot/agent/loop.py`.
+- `/mcp` supports the default `list` behavior (and explicit `/mcp list`) to show configured MCP servers and registered MCP tools.
+- Agent runtime config should be hot-reloaded from the active `config.json` for safe in-process fields such as `tools.mcpServers`, `tools.web.*`, `tools.exec.*`, `tools.restrictToWorkspace`, `agents.defaults.model`, `agents.defaults.maxToolIterations`, `agents.defaults.contextWindowTokens`, `agents.defaults.maxTokens`, `agents.defaults.temperature`, `agents.defaults.reasoningEffort`, `channels.sendProgress`, and `channels.sendToolHints`. Channel connection settings and provider credentials still require a restart.
+- nanobot does not expose local files over HTTP. If a feature needs a public URL for local files, provide your own static file server and point config such as `mediaBaseUrl` at it.
+- Generated screenshots, downloads, and other temporary user-delivery artifacts should be written under `workspace/out`, not the workspace root. Treat that as the generic delivery-artifact root for tools, MCP servers, and skills.
+- QQ outbound media sends remote `http(s)` image URLs directly. For local QQ images, try `file_data` upload first. If `mediaBaseUrl` is configured, keep the URL-based path available as a fallback for SDK/runtime compatibility; without it, there is no URL fallback.
+- `/skill` shells out to `npx clawhub@latest`; it requires Node.js/`npx` at runtime.
+- `/skill uninstall` runs in a non-interactive context, so keep passing `--yes` when shelling out to ClawHub.
+- Treat empty `/skill search` output as a user-visible "no results" case rather than a silent success. Surface npm/registry failures directly to the user.
+- Never hardcode `~/.nanobot/workspace` for skill installation or lookup. Use the active runtime workspace from config or `--workspace`.
+- Workspace skills in `<workspace>/skills/` take precedence over built-in skills with the same directory name.
+
+## Multi-Instance Channel Notes
+The repository supports multi-instance channel configs through `channels.<name>.instances`. Each
+instance must define a unique `name`, and runtime routing uses `channel/name` rather than
+`channel:name`.
+
+- Supported multi-instance channels currently include `whatsapp`, `telegram`, `discord`,
+  `feishu`, `mochat`, `dingtalk`, `slack`, `email`, `qq`, `matrix`, and `wecom`.
+- Keep backward compatibility with single-instance configs when touching channel schema or docs.
+- If a channel persists local runtime state, isolate it per instance instead of sharing one global
+  directory.
+- `matrix` instances should keep separate sync/encryption stores.
+- `mochat` instances should keep separate cursor/runtime state.
+- `whatsapp` multi-instance means multiple bridge processes, usually with different `bridgeUrl`,
+  `BRIDGE_PORT`, and `AUTH_DIR` values.

+- Keep each `instances[].name` unique within the same channel.
+- Single-instance config is still supported; switch to `instances` only when you need multiple

+- Replies, sessions, and routing use `channel/name`, for example `telegram/main` or `qq/bot-a`.
+- `matrix` instances automatically use isolated `matrix-store/<instance>` directories.
+- `mochat` instances automatically use isolated runtime cursor directories.

 Now send a message to the bot from QQ — it should respond!

+For local image files, nanobot always tries `file_data` upload first. When `mediaBaseUrl` is
+configured, nanobot also maps the same local file onto that public URL and can fall back to the

 ## 🧩 Multiple Instances

+Run multiple nanobot instances simultaneously with separate configs and runtime data. Use `--config` as the main entrypoint. Optionally pass `--workspace` during `onboard` when you want to initialize or update the saved workspace for a specific instance.
 
 ### Quick Start
 
+If you want each instance to have its own dedicated workspace from the start, pass both `--config` and `--workspace` during onboarding.
+
+**Initialize instances:**
+
+```bash
+# Create separate instance configs and workspaces
+nanobot onboard --config ~/.nanobot-telegram/config.json --workspace ~/.nanobot-telegram/workspace
+nanobot onboard --config ~/.nanobot-discord/config.json --workspace ~/.nanobot-discord/workspace

+```
+
+**Configure each instance:**
+
+Edit `~/.nanobot-telegram/config.json`, `~/.nanobot-discord/config.json`, etc. with different channel settings. The workspace you passed during `onboard` is saved into each config as that instance's default workspace.

 ### Notes
 
+- nanobot does not expose local files itself. If you rely on local media delivery such as QQ
+  screenshots, serve the relevant delivery-artifact directory with your own HTTP server and point
+  `mediaBaseUrl` at it.

+| `/stop` | Stop the current task |
+| `/restart` | Restart the bot process |
+| `/help` | Show command help |
+
+`/skill` uses the active workspace for the current process, not a hard-coded
+`~/.nanobot/workspace` path. If you start nanobot with `--workspace`, skill install/uninstall/list/update
+operate on that workspace's `skills/` directory.
+
+`/skill search` can legitimately return no matches. In that case nanobot now replies with a
+clear "no skills found" message instead of leaving the channel on a transient searching state.
+If `npx clawhub@latest` cannot reach the npm registry, nanobot also surfaces the registry/network
+error directly so the failure is visible to the user.

-# Channel Plugin Guide
-
-Build a custom nanobot channel in three steps: subclass, package, install.
-
-## 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
-
-```

-
-        return web.json_response({"ok": True})

-
-### 2. Register the Entry Point
-
-```toml
-# pyproject.toml
-[project]
-name = "nanobot-channel-webhook"
-version = "0.1.0"
-dependencies = ["nanobot", "aiohttp"]
-
-[project.entry-points."nanobot.channels"]
-webhook = "nanobot_channel_webhook:WebhookChannel"
-
-[build-system]
-requires = ["setuptools"]
-build-backend = "setuptools.backends._legacy:_Backend"
-```
-
-The key (`webhook`) becomes the config section name. The value points to your `BaseChannel` subclass.
-
-### 3. Install & Configure
-
-```bash
-pip install -e .
-nanobot plugins list      # verify "Webhook" shows as "plugin"
-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. |
-
-### 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. |
-| `is_allowed(sender_id)` | Checks against `config["allowFrom"]`; `"*"` 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 Groq Whisper (if configured). |
-| `is_running` | Returns `self._running`. |
-
-### 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      # may contain: "_progress" (bool) for streaming chunks,
-                        #              "message_id" for reply threading
-```
-
-## Config
-
-Your channel receives config as a plain `dict`. Access fields with `.get()`:
-
-```python
-async def start(self) -> None:
-    port = self.config.get("port", 9000)
-    token = self.config.get("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 {"enabled": False, "port": 9000, "allowFrom": []}
-```
-
-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` |
-
-## Local Development
-
-```bash
-git clone https://github.com/you/nanobot-channel-webhook
-cd nanobot-channel-webhook
-pip install -e .
-nanobot plugins list    # should show "Webhook" as "plugin"
-nanobot gateway         # test end-to-end
-```
-
-## Verify
-
-```bash
-$ nanobot plugins list
-
-  Name       Source    Enabled
-  telegram   builtin  yes
-  discord    builtin  no
-  webhook    plugin   yes
-```
