Key Components

1. CLI Core — Two implementations: Python-based OpenSIN (free) and TypeScript-based OpenSIN-Code (pro/subscription). Both feature ReAct loops, tool systems, MCP clients, hook systems, and subagent delegation.

2. A2A Protocol — Agent-to-Agent communication standard. Each agent has its own MCP server, Telegram bot, and can delegate tasks to other agents.

3. OpenSIN Bridge — Chrome extension with 39 MCP tools. Provides video recording, stealth mode, cookie management, webRequest logging, and WebSocket-based MCP server on HuggingFace.

4. n8n Orchestration — Workflow engine on OCI VM (92.5.60.87) handling inbound work items, PR watching, token rotation, and fleet coordination.

5. Supabase Database — Central PostgreSQL database on OCI VM (200GB) serving as the persistent data layer for all agents.
