@e9n/pi-channels

Two-way channel extension for pi — 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
