What problem does it solve? Landing a finished change involves more than a git push: commits need a correlation trailer so CI hooks can stamp later pipeline stages, merge and push operations must be recorded on the DefProd change, and delivered user stories must be advanced to completed. This Skill automates that final land stage of the DefProd change workflow so nothing downstream loses track of the change. ## Core Features & Use Cases - Correlation trailer commits: Appends the Change: <product-slug>/CHG-NN trailer to every commit so CI/CD hooks can resolve the change from a push range, including in multi-product monorepos. - Stage stamping around merge/push: Calls startChangeStage before and finishChangeStage after each merge or push it performs, reporting the driver (agent or human) and honoring the stage's consent mode. - Safe trunk integration: Integrates a diverged trunk via fast-forward or merge commit, never rebasing it, and uses git cherry to detect duplicate commits before merging. - Story completion: After a successful landing, evaluates every acceptance criterion on each linked user story and patches wholly delivered stories to completed via the DefProd MCP server. - Use Case: After the test stage passes on change CHG-12, invoke this Skill to commit with the trailer, merge the change branch into main, push to origin, stamp the merge and push stages, clear the worktree pin, and mark the delivered stories completed. ## Quick Start Ask the agent to land the current change by committing with the Change trailer, merging and pushing per the repo's flow, and completing its delivered user stories.
