# @e9n/clanker-channels
Two-way channel extension for [clanker](https://github.com/espennilsen/clanker) — route messages between agents and Telegram, Slack, webhooks, or custom adapters.
## Features
- **Telegram adapter** — bidirectional via Bot API; polling, voice/audio transcription, `allowedChatIds` filtering
- **Slack adapter** — bidirectional via Socket Mode + Web API
- **Webhook adapter** — outgoing HTTP POST to any URL
- **Chat bridge** — incoming messages are routed to the agent as prompts; responses sent back automatically; persistent (RPC) or stateless mode
- **Event API** — `channel:send`, `channel:receive`, `channel:register` for inter-extension messaging
- **Custom adapters** — register at runtime via `channel:register` event
## Settings
Add to `~/.clanker/agent/settings.json` or `.clanker/settings.json`:
```json
