description	Cut a new version of one of the owner's public GitHub repos. Use when the owner asks to publish, ship, or release a version (patch/minor/major bump, CHANGELOG promotion, tag, GitHub Release). Adapts the steps to the repo lock (PR workflow vs direct-to-main) and docs language.

Release procedure

Pick the bump per semantic versioning: patch for bug-fixes only, minor for any new user-visible feature, major for breaking changes that require user or operator action. Use today's date.

0. Read the repo profile first

Read Lock: and Docs language: from the ## Repo profile section of the repo's root CLAUDE.md (see the committing skill). The lock decides whether you cut the release on a feature branch through a pull request or straight on main. The docs language decides the CHANGELOG wording. If the section is missing, infer, confirm once, then write the four-line ## Repo profile marker into the root CLAUDE.md yourself (the block is in the scaffolding-repos skill, step 5). Reach for the full scaffolding-repos skill only if the repo also lacks its other generic files.

1. Pre-flight: run the committing checklist

A release ships the docs, not just the code, so before bumping anything run the committing pass over everything since the last release (the range <last-tag>..HEAD, with <last-tag> from git describe --tags --abbrev=0; on a first release, with no tag yet, the pass covers the whole history): confirm the docs are current and that no change left an existing doc stale, update any CLAUDE.md the work invalidated or extended, and prune comments to the strictly useful. Then make sure [Unreleased] is complete: every user-visible change since the last tag has a bullet, there are no duplicates, and it reads cleanly for a human. A release is the worst moment to find the changelog is missing entries.

If the project has a typecheck or build step, run it now and confirm it passes before you bump anything. This matters most when publishing the Release triggers a build (see step 5): a broken build is cheap to find before the tag and painful to find after. When the real build only runs in Docker or CI and is not reachable locally, run the cheapest equivalent checks instead (syntax check the changed sources, parse any JSON or config they touch), and tell the owner the actual build will run in CI when the tag is pushed, so they know it is still unverified at tag time.

2. Bump the version

Find where the version lives and bump it:

• Node: bump version in package.json, and the version in its package-lock.json in exactly two places, the top object and packages."". Edit only those version keys: a dependency can carry the same number by coincidence, so never touch a node_modules/* or other dependency entry, and never blind-replace the old version string across the lockfile. Two layouts go past the single package:

  • Workspace monorepo: bump every workspace package.json and the version of each matching packages.<workspace> node in the lockfile. Miss those and the workspace nodes stay behind, which makes npm ci reject the lockfile as out of sync and breaks any Docker build that runs it.
  • Several independent packages side by side, each with its own package-lock.json and no workspaces (say a root package and a server/ package): apply the same two-occurrence rule to each lockfile separately.

  No dependency changes belong in a release commit.

• Other ecosystems: pyproject.toml / Cargo.toml / *.csproj / composer.json and their lockfiles, as applicable.

• Claude Code plugin: bump version in .claude-plugin/plugin.json, then validate the manifest (claude plugin validate ., or npx -y @anthropic-ai/claude-code plugin validate . when the CLI is not on PATH).

• Content-only repos (a skill, docs): there is no manifest. The tag is the version; there is nothing to bump.

3. Promote the CHANGELOG

In CHANGELOG.md, rename [Unreleased] to [X.Y.Z] - YYYY-MM-DD and add a fresh empty [Unreleased] section above it. Re-read every bullet in the section being promoted and apply the tightening rule from the committing skill (short sentences, no implementation detail, grouped under the standard English change-type names). Never rewrite already-released sections.

For example, a ## [Unreleased] carrying this session's bullets becomes ## [1.4.0] - 2026-05-27 (today's date), with a new empty ## [Unreleased] inserted above it.

4. Commit, then follow the lock

Make one commit: chore(release): cut version X.Y.Z (conventional, Co-Authored-By trailer kept). Before tagging, confirm the tag number, the manifest version(s) just bumped, and the new CHANGELOG heading all carry the same X.Y.Z; a mismatch here is the classic release-day bug and is painful to fix once the tag is public. Also confirm the working tree is clean (git status) and HEAD is the commit you mean to tag, since a public tag is cheap to create and costly to move.

Lock: locked:

1. Commit on the feature branch and push. If no pull request exists yet, give the owner the title and body to paste.
2. The owner merges the pull request. This is the human gate of a locked repo; do not bypass it. Tell the owner explicitly and wait for confirmation before continuing. (The Release itself is published in the last sub-step below, once the tag exists.)
3. After merge is confirmed: git checkout main && git pull, then git tag -a vX.Y.Z -m "vX.Y.Z" and git push origin vX.Y.Z. The tag message is just the version, in both lock modes: the story lives in the CHANGELOG and the Release notes, not in the tag. Delete the feature branch, local first then remote (git branch -d <branch> then git push origin --delete <branch>). On a squash-merge repo the branch commits were flattened into one new commit on main, so they are not ancestors of main and git branch -d can refuse with "not fully merged"; the work is safely merged, so use git branch -D to force it.
4. Walk the owner through the GitHub Releases page: select the tag just pushed and paste the relevant CHANGELOG section as the release body. If gh is installed and authenticated (gh auth status), you may offer instead to run gh release create vX.Y.Z --notes-file <file> once the owner approves. Always pass the body through --notes-file, never inline --notes "...": a multi-line body inline invites shell quoting accidents (a stray @, an unescaped quote). Without --title, gh uses the tag name as the Release title, which is fine; add --title "..." only if you want a different label.

Lock: free:

1. Commit on main, tag vX.Y.Z, and push both main and the tag.
2. Publish the GitHub Release: walk the owner through the Releases page with the CHANGELOG section, or, if gh is authenticated and the owner approves, gh release create vX.Y.Z --notes-file <file>.

If the tag pushed but the Release did not publish (either lock mode), the tag is fine: do not retag, just re-run the Release step (gh release create vX.Y.Z --notes-file <file> again, or the Releases page). Creating a second tag for the same version is the thing to avoid.

5. Confirm the release automation

If there is no workflow under .github/workflows/, there is no automation to confirm; skip this step.

Many of these repos publish on a tag or Release event (a Docker image, an npm package, a GitHub Pages build). Before relying on it, read the on: trigger of the publishing workflow under .github/workflows/, because it decides when the automation fires and what to watch:

• on: push: tags: fires when you push the tag (step 4), before the Release exists. The Release you publish next is then only a notes wrapper, and the build is likely already running or finished by the time you publish it.
• on: release: types: [published] fires only when you publish the Release; nothing runs at the tag push.

Either way, confirm the run succeeded instead of only telling the owner it was triggered: gh run list --workflow=<file> (or gh run watch) after the tag push. On a tag trigger especially, a failed build means the image or package never publishes even though the tag and Release already exist, so without this check the failure goes unnoticed.

When the repo is a Claude Code plugin, the release does not propagate on its own: remind the owner that each machine with the plugin installed picks it up through /plugin update <name> or Claude Code's automatic update.
