What problem does it solve? It turns a detailed implementation plan into verified, published code changes without scope creep, unsafe git operations, or unverified closeouts, so a single agent thread can carry a bounded change end to end. ## Core Features & Use Cases - Bounded plan execution: Reads a detailed plan artifact and applies only its declared ## Changes section, stopping with a diagnostic if work falls outside the plan. - Verification and acceptance reduction: Runs every command in the plan's ## Verification section and checks each ## Acceptance criteria item, reporting pass/fail status per item. - Safe git workflow: Establishes a dedicated worktree and branch before editing, enforces a git safety invariant, and publishes a draft or ready PR via the runtime publication primitive. - Mandatory reflection closeout: Writes a structured reflection and updates the plan manifest lifecycle for every non-trivial run. - Use Case: After a planning skill produces a detailed plan for a bug fix, invoke this skill to implement the changes in an isolated worktree, run the test suite, and open a pull request with the verified diff. ## Quick Start Execute the detailed plan at the given artifact path, verify it against its acceptance criteria, and publish the result as a pull request.
