How to Coordinate Role-Based CLI Seats & Session Handovers for AI Agents: A Governance MCP Server

Description and use

Multiple AI agents running in the same terminal can cause race conditions, session handover amnesia, and destructive commands. CliSeat provides single‑writer seat locks, a tamper‑evident handover ledger, and automatic seat reclamation.

Problem

Multiple AI agent sessions running in the same terminal can cause race conditions, session handover amnesia, and out-of-domain execution.

Outcome

Agents can safely coordinate repository mutations, preserve context across handovers, and prevent accidental destructive actions.

Workflow

• 1. Agent claims a domain seat via CliSeat’s SeatManager.
• 2. If the seat is occupied, the claim is rejected with holder info.
• 3. Agent performs its tasks while holding the seat.
• 4. Upon completion or timeout, agent records a handover brief to HandoverLedger.
• 5. CliSeat logs the brief with a SHA‑256 hash in an SQLite WAL ledger.
• 6. Next agent claims the seat and reads the ledger for context.

Evidence

When another session attempts to mutate the repository while domain:cli is occupied, the claim is rejected immediately with the current holder's session ID and remaining lease time.

Source

CliSeat persists every handover to an atomic SQLite WAL database sealed with a SHA-256 state hash.
