What problem does it solve? Standard diff views fragment the story of a large pull request or stacked PRs across pages, making it hard for reviewers to understand what changed and why. This Skill turns any diff into a readable two-column walkthrough: a curated prose chapter on the left and a comprehensive, surface-grouped code map on the right. ## Core Features & Use Cases - Two-column walkthrough generation: Produces prose.md (a continuous narrative naming consequences), map.md (every hunk in the diff grouped by surface with framing paragraphs), and diff.patch (the verbatim unified diff). - Chip cross-linking: Inline line-range markdown links in the prose point directly at hunks in the map, so readers can jump from a consequence to the exact mechanics. - Coverage audit: A built-in audit checklist verifies every + line in the diff is covered by a map fence and that addition/deletion totals match the change header. - Use Case: You have a 6-PR stack touching 40 files. Run this Skill to produce a walkthrough where reviewers read a short prose chapter for the story and consult the map for every hunk, instead of scrolling a fragmented diff view. ## Quick Start Generate a change story for the current pull request using its diff, title, and description.
