## Implementation Complete ✅ Successfully implemented the WebSocket-to-Claude-Code bridge as specified. ### What Was Built **agent-bridge.go** - A Go application that: - Starts Claude Code in a PTY for natural terminal interaction - Connects to Rails ActionCable WebSocket at `ws://host.docker.internal:3000/cable` - Subscribes to `AgentChannel` with agent type identifier - Receives commands from Rails and passes them to Claude's stdin - Displays all Claude output for full observability - Auto-reconnects to WebSocket on disconnect (5s backoff) - Handles terminal resize signals (SIGWINCH) - Uses color-coded logging for bridge status messages **Docker Integration**: - Added multi-stage Go builder to Dockerfile.sandbox - Binary compiled and copied to `/usr/local/bin/agent-bridge` - Updated run-claude-agent.rb to exec agent-bridge instead of claude directly **Configuration**: - `AGENT_TYPE` env var: worker|reviewer|orchestrator - `RAILS_WS_URL` env var: WebSocket endpoint (defaults to ws://host.docker.internal:3000/cable) ### Testing Results ✅ Code compiles successfully ✅ PTY integration works - Claude Code starts properly ✅ WebSocket client attempts connection (fails gracefully when Rails not running) ✅ Terminal resize handling works ✅ Color-coded status messages display correctly ### Files Changed - **New**: agent-bridge.go, go.mod, go.sum - **Modified**: Dockerfile.sandbox, run-claude-agent.rb ### Pull Request Created: https://github.com/RoM4iK/tinker/pull/16 Ready for review and end-to-end testing with live Rails server.
