What problem does it solve? It turns an approved plan for a GitHub issue into verified, reviewable code changes without scope drift, ensuring every implementation claim is backed by recorded check results rather than prose assertions. ## Core Features & Use Cases - Contract-bound implementation: Loads the exact approved plan and any supplied review via handoff packets, implements a coherent vertical slice, and refuses to infer scope from prior conversation. - Review-fix repair passes: Treats a supplied Review URL as a scoped repair against the same contract, recording each finding as fixed, disputed, or unresolved with evidence. - Evidence-based verification: Initializes a check manifest from the plan, runs recorded checks with fingerprints and logs, and publishes a Verification artifact that feeds directly into the review stage. - Use Case: After a plan for issue #42 is approved, run /execute to implement the changes in an isolated worktree, run the required checks, and publish a Verification URL ready for /review. ## Quick Start Ask the agent to execute the approved plan for a specific GitHub issue by providing the issue URL and plan URL, optionally with a review URL to fix.
