Session Stop Skill

Graceful session close, pause, or verification. Three intents: Pause | Finish | Verify.

All session operations use atlas-session MCP tools directly (prefixed session_* and contract_*). Use ToolSearch to discover them.

Hard Invariants

1. User authority is absolute — AI NEVER closes without confirmation.
2. Human-visible memory only — All state lives in files.
3. Trust separation — for bounty verify, spawn a separate finality Task agent. Never the same agent that submits.
4. AtlasCoin is optional — if down, skip bounty steps and continue.
5. Idempotent — Running /stop on an already-closed session exits cleanly.
6. Archive after verification — Soul purpose is archived AFTER bounty settlement, not before.

UX Contract

• User sees ONE intent question, then results. Nothing else.
• No step announcements, no narration, no internal process descriptions.
