What problem does it solve?
It helps implement an approved technical plan in a controlled, verifiable way by updating plan progress, running checks, and committing only the intended changes for each phase.
Core Features & Use Cases
- Resolves and validates the plan path: Accepts a change-id with optional phase, or a direct plan path, and refuses archived changes under context/archive.
- Executes phase-by-phase implementation with state in the plan: Reads the authoritative ## Progress section, creates and updates per-phase tasks, and advances from the first pending checkbox.
- Enforces a verification and commit ritual: Runs success criteria checks, pauses for manual verification confirmation, stages only the touched files, and records the phase commit SHA back into the Progress rows.
- Detects and handles mismatches: If reality diverges from the plan, it stops to explain the issue and asks the user whether to adapt, skip, or re-plan.
- Supports safe phase continuation and resuming: Uses existing [x] marks in ## Progress as the resume source of truth.
