 - `/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.
+- `/status` should return plain-text runtime info for the active session and stay wired into `/help` plus Telegram's command menu/localization coverage.
+- 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`, `channels.sendToolHints`, and `channels.voiceReply.*`. 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 can send remote rich-media URLs directly. For local QQ media under `workspace/out`, use direct `file_data` upload only; do not rely on URL fallback for local files. Supported local QQ rich media are images, `.mp4` video, and `.silk` voice.
+- `channels.voiceReply` currently adds TTS attachments on supported outbound channels such as Telegram, and QQ when the configured TTS endpoint returns `silk`. Preserve plain-text fallback when QQ voice requirements are not met.
+- Voice replies should follow the active session persona. Build TTS style instructions from the resolved persona's prompt files, and allow optional persona-local overrides from `VOICE.json` under the persona workspace (`<workspace>/VOICE.json` for default, `<workspace>/personas/<name>/VOICE.json` for custom personas).
+- `channels.voiceReply.url` may override the TTS endpoint independently of the chat model provider. When omitted, fall back to the active conversation provider URL. Keep `apiBase` accepted as a compatibility alias.
 - `/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.

+
+`voiceReply` currently adds a voice attachment while keeping the normal text reply. For QQ voice
+delivery, use `responseFormat: "silk"` because QQ local voice upload expects `.silk`. If `apiKey`
+and `apiBase` are omitted, nanobot falls back to the active provider credentials; use an
+OpenAI-compatible TTS endpoint for this.
+`voiceReply.url` is optional and can point either to a provider base URL such as
+`https://api.openai.com/v1` or directly to an `/audio/speech` endpoint. If omitted, nanobot uses
+the current conversation provider URL. `apiBase` remains supported as a legacy alias.
+
+Voice replies automatically follow the active session persona. nanobot builds TTS style
+instructions from that persona's `SOUL.md` and `USER.md`, so switching `/persona` changes both the
+text response style and the generated speech style together.
+
+If a specific persona needs a fixed voice or speaking pattern, add `VOICE.json` under the persona
+workspace:

+- Default persona: `<workspace>/VOICE.json`
+- Custom persona: `<workspace>/personas/<name>/VOICE.json`

+# 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
+
+```

+            media=media,
+        )
+
+        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. Automatically sets `_wants_stream` if `supports_streaming` is true. |
+| `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). |
+| `supports_streaming` (property) | `True` when config has `"streaming": true` **and** subclass overrides `send_delta()`. |
+| `is_running` | Returns `self._running`. |
+
+### Optional (streaming)
+
+| Method | Description |
+|--------|-------------|
+| `async send_delta(chat_id, delta, metadata?)` | 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      # may contain: "_progress" (bool) for streaming chunks,
+                        #              "message_id" for reply threading
+```
+
+## 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) -> None:
+    meta = metadata or {}
+
+    if meta.get("_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)
+```
+
+**Metadata flags:**
+
+| Flag | Meaning |
+|------|---------|
+| `_stream_delta: True` | A content chunk (delta contains the new text) |
+| `_stream_end: True` | Streaming finished (delta is empty) |
+| `_resuming: True` | More streaming rounds coming (e.g. tool call then another response) |
+
+### Example: Webhook with Streaming
+
+```python
+class WebhookChannel(BaseChannel):
+    name = "webhook"
+    display_name = "Webhook"
+
+    def __init__(self, config, bus):
+        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) -> None:
+        meta = metadata or {}
+        if meta.get("_stream_end"):
+            text = self._buffers.pop(chat_id, "")
+            # Final delivery — format and send the complete message
+            await self._deliver(chat_id, text, final=True)
+            return
+
+        self._buffers.setdefault(chat_id, "")
+        self._buffers[chat_id] += delta
+        # Incremental update — push partial text to the client
+        await self._deliver(chat_id, self._buffers[chat_id], 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?)` | Override to handle streaming chunks. No-op by default. |
+| `supports_streaming` (property) | Returns `True` when config has `streaming: true` **and** subclass overrides `send_delta`. |
+
+## 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
+```
