What problem does it solve? Writing release notes by hand means digging through git history, changesets, and merged PRs, then formatting everything consistently. This Skill automates that process for Paperclip's calendar-versioned stable releases, producing a ready-to-review changelog file. ## Core Features & Use Cases - Automated changelog generation: Reads commits since the last stable tag, .changeset/*.md files, and merged PRs via gh to build releases/vYYYY.MDD.P.md. - Breaking change detection: Scans migrations, schema diffs, API routes, and BREAKING: commit signals, then writes an upgrade path for each breaking change. - PR and contributor attribution: Adds inline PR links and @-mentions, builds an alphabetized Contributors section, and excludes bots and founders. - Release Case upsert: Optionally syncs the changelog into a Paperclip release Case via the Cases API, with stale-revision retry handling. - Use Case: Before cutting stable release v2026.318.0, run this Skill to produce a categorized changelog with Highlights, Improvements, Fixes, and an Upgrade Guide, ready for maintainer sign-off. ## Quick Start Generate the stable release changelog for the next Paperclip release using commits and merged PRs since the last stable tag.
