It enforces role-based single-writer seat locks across domains like cli, db and infra, logs SHA-256-hashed session handover briefs to an immutable SQLite WAL ledger, reaps abandoned seats via heartbeats, and redacts credentials from command I/O.", "body_md": "In 2026, multi-agent software engineering swarms (Claude Desktop, Cursor, OpenAI Codex, Roo-Code, AutoGen) frequently operate directly on local repositories and shell environments. Teams deploy autonomous agents to build features, fix bugs, run test suites, and execute deployments.\n\nHowever, operating multiple agent sessions in the same terminal environment quickly exposes three critical concurrency and governance hazards:\n\n`domain:cli`) accidentally runs destructive database or cloud infrastructure commands without boundary enforcement.\nTo eliminate these hazards, we built **CliSeat**: an open Model Context Protocol (MCP) server in Python that enforces **role-based single-writer seat locks**, logs cryptographically hashed **session handover briefs** to an immutable SQLite WAL ledger, automatically reaps abandoned seats via heartbeats, and redacts sensitive credentials from command I/O.\n\nCliSeat acts as an authoritative governance sidecar between your AI assistants and the host shell:\n\n```\n           +-----------------------------------------------+\n           |       AI Agent / LLM (Claude, Cursor, Swarm)  |\n           +-----------------------------------------------+\n                                   |\n                          (MCP JSON-RPC Tools)\n                                   v\n           +-----------------------------------------------+\n           |            CliSeat Pro MCP Server             |\n           +-----------------------------------------------+\n              /                    |                    \\\n             v                     v                     v\n   +-------------------+  +-------------------+  +-------------------+\n   | Single-Writer Seat|  | Handover Ledger   |  | Command Governor  |\n   | Lock (domain:cli) |  | (SQLite WAL SHA256|  | & Secret Masking  |\n   +-------------------+  +-------------------+  +-------------------+\n             \\                     |                     /\n              +--------------------+--------------------+\n                                   |\n                                   v\n                      +-------------------------+\n                      |   Governed Shell I/O    |\n                      +-------------------------+\n```\n\nOnly one agent session should hold mutation rights over a specific architectural domain at any given moment.\n\nCliSeat manages domain seats (`domain:cli`, `domain:db`, `domain:infra`):\n\n``` python\nclass SeatManager:\n    def __init__(self):\n        self.seats = {}\n\n    def claim_seat(self, seat_id: str, holder_session_id: str, lease_ttl_sec: int = 180):\n        seat = self.get_or_create(seat_id)\n        now = datetime.now(timezone.utc).isoformat()\n\n        # Reject if held by an active session\n        if seat.status == \"occupied\" and not seat.is_expired():\n            if seat.holder != holder_session_id:\n                return {\n                    \"status\": \"rejected\",\n                    \"error\": f\"Seat '{seat_id}' is already held by '{seat.holder}'.\",\n                    \"seat\": seat.to_dict()\n                }\n            #
