## 📢 News
> [!IMPORTANT]
> **Security note:** Due to `litellm` supply chain poisoning, **please check your Python environment ASAP** and refer to this [advisory](https://github.com/HKUDS/nanobot/discussions/2445) for details. We have fully removed the `litellm` dependency in [this commit](https://github.com/HKUDS/nanobot/commit/3dfdab7).
- **2026-03-21** 🔒 Replace `litellm` with native `openai` + `anthropic` SDKs. Please see [commit](https://github.com/HKUDS/nanobot/commit/3dfdab7).
- **2026-03-20** 🧙 Interactive setup wizard — pick your provider, model autocomplete, and you're good to go.
- **2026-03-19** 💬 Telegram gets more resilient under load; Feishu now renders code blocks properly.
- **2026-03-18** 📷 Telegram can now send media via URL. Cron schedules show human-readable details.
- **2026-03-17** ✨ Feishu formatting glow-up, Slack reacts when done, custom endpoints support extra headers, and image handling is more reliable.
- **2026-03-16** 🚀 Released **v0.1.4.post5** — a refinement-focused release with stronger reliability and channel support, and a more dependable day-to-day experience. Please see [release notes](https://github.com/HKUDS/nanobot/releases/tag/v0.1.4.post5) for details.
- **2026-03-15** 🧩 DingTalk rich media, smarter built-in skills, and cleaner model compatibility.
- **2026-03-14** 💬 Channel plugins, Feishu replies, and steadier MCP, QQ, and media handling.

- **Streaming replies** (default in nanobot): add **`cardkit:card:write`** (often labeled **Create and update cards** in the Feishu developer console). Required for CardKit entities and streamed assistant text. Older apps may not have it yet — open **Permission management**, enable the scope, then **publish** a new app version if the console requires it.
- If you **cannot** add `cardkit:card:write`, set `"streaming": false` under `channels.feishu` (see below). The bot still works; replies use normal interactive cards without token-by-token streaming.
- **Events**: Add `im.message.receive_v1` (receive messages)
- Select **Long Connection** mode (requires running nanobot first to establish connection)

### Channel Settings
Global settings that apply to all channels. Configure under the `channels` section in `~/.nanobot/config.json`:
```json
{
"channels": {
"sendProgress": true,
"sendToolHints": false,
"sendMaxRetries": 3,
"telegram": { ... }
}
}
```
| Setting | Default | Description |
|---------|---------|-------------|
| `sendProgress` | `true` | Stream agent's text progress to the channel |
| `sendToolHints` | `false` | Stream tool-call hints (e.g. `read_file("…")`) |
| `sendMaxRetries` | `3` | Max delivery attempts per outbound message, including the initial send (0-10 configured, minimum 1 actual attempt) |
#### Retry Behavior
When a channel send operation raises an error, nanobot retries with exponential backoff:
- **Attempt 1**: Initial send
- **Attempts 2-4**: Retry delays are 1s, 2s, 4s
- **Attempts 5+**: Retry delay caps at 4s
- **Transient failures** (network hiccups, temporary API limits): Retry usually succeeds
- **Permanent failures** (invalid token, channel banned): All retries fail
> [!NOTE]
> When a channel is completely unavailable, there's no way to notify the user since we cannot reach them through that channel. Monitor logs for "Failed to send to {channel} after N attempts" to detect persistent delivery failures.

| `channels.*.allowFrom` | `[]` (deny all) | Whitelist of user IDs. Empty denies all; use `["*"]` to allow everyone. |
### Timezone
Time is context. Context should be precise.
By default, nanobot uses `UTC` for runtime time context. If you want the agent to think in your local time, set `agents.defaults.timezone` to a valid [IANA timezone name](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones):
```json
{
"agents": {
"defaults": {
"timezone": "Asia/Shanghai"
}
}
}
```
This affects runtime time strings shown to the model, such as runtime context and heartbeat prompts. It also becomes the default timezone for cron schedules when a cron expression omits `tz`, and for one-shot `at` times when the ISO datetime has no explicit offset.
Common examples: `UTC`, `America/New_York`, `America/Los_Angeles`, `Europe/London`, `Europe/Berlin`, `Asia/Tokyo`, `Asia/Shanghai`, `Asia/Singapore`, `Australia/Sydney`.
> Need another timezone? Browse the full [IANA Time Zone Database](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
## 🧩 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.

| `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
```

Inbound:
- Parse QQ botpy messages (C2C / Group)
- Download attachments to media dir using chunked streaming write (memory-safe)
- Publish to Nanobot bus via BaseChannel._handle_message()
- Content includes a clear, actionable "Received files:" list with local paths
Outbound:
- Send attachments (msg.media) first via QQ rich media API (base64 upload + msg_type=7)
- Then send text (plain or markdown)
- msg.media supports local paths, file:// paths, and http(s) URLs
Notes:
- QQ restricts many audio/video formats. We conservatively classify as image vs file.
- Attachment structures differ across botpy versions; we try multiple field candidates.
