cutover-plan

name	cutover-plan
description	Use this skill when planning the staged transition from the TypeScript implementation to the Python implementation with minimal behavior drift.

Your task is to produce a staged migration plan.

Plan must include:

• subsystem order
• blockers
• parity gates
• rollback points
• documentation checkpoints
• dual-run or shadow-run opportunities
• acceptance criteria per slice

Preferred migration order:

1. architecture mapping
2. invariant extraction
3. test harness
4. pure utility modules
5. config/settings adapters
6. permissions/sandbox
7. session persistence
8. MCP/plugin lifecycle
9. query/runtime loop
10. CLI/REPL integration
11. cutover and cleanup
