What problem does it solve? Merging a finished feature branch into the preprod staging branch involves PR creation, conflict resolution, documentation audits, and cleanup; this Skill automates that entire gate by pushing a signal file that a GitHub Action turns into an auto-merged PR. ## Core Features & Use Cases - Signal-based auto-merge: Writes and pushes a .pr-description.md signal file so the GitHub Action opens and auto-merges the PR from feature/<name> to preprod, reusing any open /review PR. - Conflict pre-resolution: Merges preprod into the current branch locally first, with a documented discipline for resolving conflicts before they can stall the PR. - Docs and spec gating: Runs a docs-updater agent and, when a specification is connected, enforces a drift gate whose run records are committed as an auditable ledger. - Use Case: After finishing a feature on a claude/ session branch, invoke the skill to retire the feature context, generate a structured PR description, and hand the merge to CI without touching the GitHub UI. ## Quick Start Merge my current feature branch to preprod with the PR title "Add user notification preferences".
