What problem does it solve? Non-trivial repository changes often ship without consistent local validation, documentation updates, or an independent review of the exact commit being landed. This Skill enforces a disciplined local gate so every landing commit is implemented, tested, documented, and reviewed before it is accepted or handed off toward PR readiness. ## Core Features & Use Cases - Structured local gate: Walks changes through scope definition, implementation, build and test, documentation updates, landing commit formation, frozen-head review, and acceptance. - Frozen exact-head review: Requires review to run against an immutable base_sha..head_sha range, and invalidates prior results if any post-review commit changes the head. - Clear handoff boundaries: Delegates reviewer adapters, workspace isolation, CI recovery, and PR readiness to the review-orchestration-playbook instead of duplicating that policy. - Use Case: After finishing a feature branch, use this Skill to run the full local validation suite, update project docs, form the signed landing commit, and get that exact head reviewed before pushing. ## Quick Start Run the change delivery workflow on my current branch to validate, document, and review the landing commit before I open a PR.
