What problem does it solve? Stacked pull requests managed with Graphite often fail CI in cascading ways, and it is hard to know which branch to fix first, whether a failing check is stale, and when the stack is actually green. This Skill provides a disciplined repair loop that stabilizes the whole stack. ## Core Features & Use Cases - Stack inventory and triage: Reads structured stack topology and per-branch PR check status, classifying each PR as green, fresh-failing, pending, or needing a restack. - Lowest-first repair loop: Checks out the lowest actionable failing branch, reproduces the failure locally, fixes only that branch's blocker, amends with gt modify, and resubmits with gt submit. - Check-settling and done definition: Waits for checks to settle via wait-for-checks, distinguishes fresh from stale failures and trailing Graphite mergeability signals, and stops only when every PR has zero fresh failing checks. - Use Case: A developer has a five-PR Graphite stack where CI is red on three branches; the Skill identifies the lowest fresh failure, fixes it, restacks, and repeats until the entire stack is green. ## Quick Start Ask the agent to fix and green my current Graphite PR stack until all branch checks pass.
