description	Helper for release operations, compilation of changelogs between tags, version lockstep syncing, and promotion of GitHub releases from canary/pre-release to latest/production.

gaia-release

A skill for managing releases, compiling changelogs across tags, verifying version lockstep, and promoting releases from canary/beta to latest/production.

When to invoke

Trigger when the user requests release operations, including:

• "Compile the changelog from previous latest" / "generate release notes"
• "Mark tag vX.Y.Z as Latest" / "promote release to latest"
• "Update release notes on GitHub"
• Release bump checks and tag auditing

Do NOT use for:

• Standard git branch merging (use standard git procedures)
• Regular document sync routines (use gaia-docs-sync or similar)

Operating Contract

1. Compile Changelogs

To compile a changelog from a previous version/tag to the target tag:

1. Fetch all tags from remote to ensure your local tag list is up-to-date:

   git fetch --tags
   

2. Find the commits and tags between the starting tag and the target tag:

   git log <start_tag>..<target_tag> --decorate --oneline
   

3. Group commits by their release tags and format them into readable changelog groups:
   • Features (feat:, chore:, etc.)
   • Bug Fixes (fix:, etc.)
   • Documentation (docs:, etc.)
   • CI / Testing / Housekeeping (infra:, test:, etc.)
4. Keep the list concise and link to the relevant Pull Requests or Issues.

2. Verify / Sync Version Lockstep

If requested to update version files:

1. The four manifest files must remain in lockstep:
   • pyproject.toml
   • packages/cli-npm/package.json
   • packages/mcp/package.json
   • registry/gaia.json (gitignored pipeline-internal, but updated locally)
2. Use python3 scripts/verify_lockstep.py to check current lockstep alignment.
3. Sync versions using:

   gaia dev release <patch|minor|major> --sync
   

   Or if not bumping and only syncing manifests to the highest version:

   python3 -m gaia_cli.main dev release --sync
   

3. Promote GitHub Release to Latest / Production

⚠️ Ancestry guard (mandatory — issue: split-brain release state). Before promoting or publishing any tag, verify the tag's commit is an ancestor of main. Promoting/publishing a tag whose commit never landed on main desyncs the published version from the branch manifests, which makes sync-artifacts.yml recompute the same patch version on every subsequent merge and hard-fail on fatal: tag 'vX.Y.Z' already exists (this is exactly what happened with v6.8.9). Run this and abort if it fails:

git fetch --tags origin main
if ! git merge-base --is-ancestor "$(git rev-list -n1 <tag>)" origin/main; then
  echo "ABORT: <tag> commit is not on main — land the version-bump commit first."
  exit 1
fi

If the tag is legitimately ahead of main (e.g. the release commit is still in flight), do not promote/publish yet — merge the bump to main first, or reconcile main's manifests to the tag version so the branch owns it.

To change a canary or beta release to the latest production release on GitHub:

1. Generate the changelog/notes in a markdown file (e.g. generated-output/changelog_vX.Y.Z.md).
2. Run the gh release edit command with the appropriate flags to update the title, remove the prerelease flag, mark it as latest, and upload the notes:

   gh release edit <tag> --title "<tag>" --prerelease=false --latest --notes-file <path_to_notes.md>
   

3. Run gh release view <tag> to verify that the release shows prerelease: false and the title/notes are correct.

4. Manually Publish to PyPI

If the release needs to be manually published to PyPI (e.g., when bypassing automated CI triggers or for manual publication control):

⚠️ Apply the same ancestry guard from §3 first. Publishing a version to PyPI that main's pyproject.toml does not carry is unrecoverable (PyPI versions are immutable) and strands main behind the published version. Only publish when main's version ≥ the version being published.

1. Use the GitHub CLI to trigger the Publish gaia-cli to PyPI workflow manually. Specify the main branch as the reference, which will build the version defined in pyproject.toml on the main branch:

   gh workflow run publish-pypi.yml --ref main
   

2. Monitor the run to confirm that the build and publish steps complete successfully.

5. Code Change Constraint

• Always respect user instructions regarding code changes. If the user states "commit no code" or "just do the tagging and release," perform all tag/release modifications on GitHub directly using gh CLI commands and output the compiled changelog text in the chat, rather than committing edits to CHANGELOG.md.

Example Invocation

User: Work on tag v5.4.10 and change it as Latest. Compile the CHangelog from previous latest. I will be publishing it to pypi.
Agent:
  1. Fetches tags and inspects commits between v5.1.1 and v5.4.10.
  2. Compiles a detailed changelog grouped by release.
  3. Uses `gh release edit v5.4.10 --title "v5.4.10" --prerelease=false --latest --notes-file generated-output/changelog_v5.4.10.md` to promote the release to Latest.
  4. Verifies the status using `gh release view`.
  5. Presents the changelog to the user and confirms the release update.
