What problem does it solve? Large pull requests over 400 changed lines overwhelm reviewers, slow down merges, and hide defects. This Skill breaks oversized changes into focused, chained PRs that keep each review under a manageable budget while preserving integration order. ## Core Features & Use Cases - Strategy Selection: Chooses between Stacked PRs to main and Feature Branch Chain with a draft tracker PR based on whether slices can land independently. - Chain Context Blocks: Adds dependency diagrams, position markers, review budgets, and scope boundaries to every child PR without replacing the repo PR template. - Diff Hygiene Enforcement: Detects polluted diffs and requires retargeting or rebasing so each PR shows only its own work unit. - Use Case: A feature branch contains 1,200 changed lines. The Skill splits it into three child PRs targeting each other in sequence, each under 400 lines, with a draft tracker PR holding integration until all slices are reviewed. ## Quick Start Ask the assistant to split this oversized pull request into chained PRs using the chained-pr strategy and generate the dependency diagram for each slice.
