The body is lean — rules, workflow, output templates, anti-patterns — and assumes Claude's competence without explaining what git/App Store/Play Store are; every section earns its place. Minor repetition of the character limit across sections reinforces a critical constraint rather than padding.

Provides executable command (`git log <last-tag>..HEAD --oneline`), copy-paste output templates per store, and concrete anti-pattern examples (e.g. `chore: upgrade Gradle` → drop), with a real reference file for commit-to-bullet mapping.

A clear five-step sequence (Collect → Triage → Draft App Store → Draft Google Play → Validate) with an explicit validation checkpoint that counts characters and verifies bullets map to real commits, plus a rewrite-if-overrun loop in Anti-Patterns.

SKILL.md is a concise overview with a single one-level-deep reference (references/commit_examples.md, a real file) clearly signaled twice — content is appropriately split and easy to navigate.

Lists multiple concrete actions — "collecting git history, triaging user-impacting changes, and drafting store-compliant changelogs" plus "Enforces character limits ... tone, and bullet format" — matching the multi-action anchor.

Explicitly answers both what (generate/draft/enforce store changelogs) and when ("Use when generating release notes, app store changelog, play store release, what's new...") with explicit triggers.

The "Use when" clause covers natural terms users would say: "release notes, app store changelog, play store release, what's new, or version release notes" — good coverage of common variations.

Scoped to a clear niche (Apple App Store + Google Play mobile release notes) with distinct store-specific triggers, making conflicts with other skills unlikely.
