Breaking Change Detector
Check a diff against a package's actual public surface (exported API, wire format, CLI flags, config schema) to catch breaking changes the author didn't flag as one.
Changelog Generator
Turn a range of commits into a user-facing changelog entry, grouped by category and written for the person consuming the software, not the people who built it.
Commit Message Writer
Write a commit message that explains why a change was made, derived from the actual diff and conversation context -- not a restatement of the diff itself.
PR Description Writer
Summarize a branch's full commit range for reviewers -- what changed and why, plus a concrete test plan -- not just the latest commit's message.
Release Notes Generator
Write release notes that lead with what matters to users (highlights, breaking changes, upgrade steps) instead of a flat, chronological commit dump.
