What problem does it solve? Manually running checks across every branch of a stacked-diff workflow is tedious and error-prone: you must check out each branch, run tests, commit fixes separately, restack descendants, and only then submit. This Skill automates that entire loop for a Graphite stack while enforcing safe boundaries like clean worktrees and no weakened checks. ## Core Features & Use Cases - Bottom-to-top stack validation: Runs just on every branch from the Graphite bottom to the top, fixing failures where they occur. - Checkpoint fix commits: Creates separate fix commits via ns flow cp and restacks descendants with gt restack after each fix. - Guarded submission: Submits the stack with gt submit --no-interactive only after every branch is green, and stops on conflicts, dirty worktrees, or ambiguous branches instead of guessing. - Use Case: You have a five-branch Graphite stack and want CI-equivalent confidence before submitting; invoke the skill and it walks the stack, fixes a failing lint on branch two, commits it, restacks, and submits once all branches pass. ## Quick Start Ask the agent to run just-the-stack on my current Graphite stack and submit it once every branch passes.
