@@ -17,6 +17,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 - Realigned README, package metadata, user docs, and GitHub About guidance to the current `1,304+` catalog state and `v8.4.0` release copy.
 - Automated metadata propagation for curated docs and package copy so `npm run chain` now keeps README, package description, and the main count-sensitive user/maintainer docs aligned when the skill catalog changes.
+- Added an explicit `sync:github-about` automation path so GitHub About description, homepage, and topics can be refreshed from the same metadata source instead of being updated manually.

   - `docs/maintainers/skills-update-guide.md`
 - Updated the changelog `Unreleased` section so the post-`v8.4.0` main branch state documents both the imported skill families and the docs/About realignment.
 - Automated the recurring docs metadata maintenance by extending `tools/scripts/sync_repo_metadata.py`, wiring it into `npm run chain`, and adding a regression test so future skill-count/version updates propagate through the curated docs surface without manual patching.
+- Added a remote GitHub About sync path (`npm run sync:github-about`) backed by `gh repo edit` + `gh api .../topics` so the public repository metadata can be refreshed from the same source of truth on demand.
