Merge remote-tracking branch 'origin/main'

Trigger token consolidation before prompt usage reaches the full context window so response tokens and tokenizer estimation drift still fit safely within the model budget.

+# 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.
+- `/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.
+- 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.

+  "tools": {
+    "web": {
+      "search": {
+        "provider": "brave",

+  "tools": {
+    "web": {
+      "search": {
+        "provider": "searxng",
+        "baseUrl": "http://localhost:8080"
+      }
+    }
+  }
+}
+```
+
+`baseUrl` can point either to the SearXNG root (for example `http://localhost:8080`) or directly to `/search`.
+
+### Optional: Voice Replies
+
+Enable `channels.voiceReply` when you want nanobot to attach a synthesized voice reply on
+supported outbound channels such as Telegram. QQ voice replies are also supported when your TTS
+endpoint can return `silk`.
+
+```json
+{
+  "channels": {
+    "voiceReply": {
+      "enabled": true,
+      "channels": ["telegram"],
+      "url": "https://your-tts-endpoint.example.com/v1",
+      "model": "gpt-4o-mini-tts",
+      "voice": "alloy",
+      "instructions": "keep the delivery calm and clear",
+      "speed": 1.0,
+      "responseFormat": "opus"
+    }
+  }
+}
+```
+
+`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`
+
+Example:
+
+```json
+{

+and bridge auth/session directory.

+
+- Keep each `instances[].name` unique within the same channel.
+- Single-instance config is still supported; switch to `instances` only when you need multiple
+  bots/accounts for the same channel.
+- 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.
+- `whatsapp` instances require separate bridge processes, typically with different `BRIDGE_PORT`
+  and `AUTH_DIR` values.

+configured, nanobot also maps the same local file onto that public URL and can fall back to the

 ```
 
+## 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 |
