What problem does it solve? Large pull requests overwhelm reviewers, slow down merges, and hide defects. This Skill enforces a 400-changed-line budget by splitting oversized work into chained or stacked PRs that stay reviewable in under an hour. ## Core Features & Use Cases - Size Budget Enforcement: Splits any PR exceeding 400 changed lines unless a maintainer grants a size:exception. - Two Chain Strategies: Choose Stacked PRs to main for independently shippable slices, or a Feature Branch Chain with a draft tracker PR when the feature must integrate before landing on main. - Chain Context Metadata: Every child PR gets a dependency diagram, position marker, review budget, and rollback scope so reviewers see exactly where it fits. - Use Case: A developer finishes a 1,200-line feature. The Skill splits it into three focused PRs, each targeting its parent branch, with a tracker PR held as draft until the full chain is reviewed and merged. ## Quick Start Ask the assistant to split this oversized feature branch into chained PRs under 400 lines each with a dependency diagram.
