What problem does it solve? Large changes shipped as one giant pull request are hard to review and slow to merge. This Skill automates decomposing a big change into a stack of small, dependent PRs using the gh stack CLI extension, handling branch chaining, incremental submission, rebasing after merges, and folding in review feedback. ## Core Features & Use Cases - Stack initialization and growth: Create all group branches at once with gh stack init, or add them incrementally with gh stack add as each group's scope becomes clear. - Incremental PR submission: Submit one group's PR at a time with gh stack submit --auto, then fix up titles and bodies to match Conventional Commit and Closes #N conventions via gh pr edit. - Sync and cleanup: After earlier PRs merge, gh stack sync --prune cascade-rebases remaining branches, force-pushes safely with --force-with-lease --atomic, and prunes merged branches. - Use Case: You are implementing a multi-phase Pulumi infrastructure migration touching dozens of files. Split it into ordered groups (pulumi-1-..., pulumi-2-...), submit each as its own reviewable PR, and re-sync the stack automatically as each one merges. ## Quick Start Ask the AI to decompose the current large change into a stack of small dependent PRs using gh stack, starting with gh stack init for the first group branch.
