Messaging adapters: Telegram, Discord, Slack integration

[kovtcharov]

Problem

GAIA agents are only accessible via the CLI and Agent UI web interface. There is no way to interact with a GAIA agent through messaging platforms.

Strategic Context

From the strategy doc:

"Messaging is the interface, not an app. Adoption was driven by WhatsApp, Telegram, and Discord — not OpenClaw's web UI. Users want AI woven into existing tools."

OpenClaw supports 24 messaging platforms. GAIA supports zero. Track B calls for Phase 1: Telegram, Discord, Slack.

Proposed Architecture

Plugin-based adapter system:

1. Adapter interface — Standard message receive/send contract
2. Telegram adapter — Bot API integration (Phase 1)
3. Discord adapter — Bot integration (Phase 1)
4. Slack adapter — App integration (Phase 1)
5. Message routing — Route incoming messages to appropriate agent, return responses

Dependencies

• Agent API (OpenAI-compatible server, already exists)
• Background service (NEW-8: autonomy engine)

Acceptance Criteria

• User can text their GAIA agent on Telegram and get responses
• Discord bot integration working
• Slack app integration working
• Standard adapter interface for community contributions
