description	End-to-end release cutting for a GitHub repo: decide the next semantic version from the Conventional Commits since the last tag, draft proper release notes (GitHub auto-generated via `.github/release.yml`, or hand-curated grouped by change type with highlights and upgrade notes for breaking changes), create and push an annotated tag, publish the GitHub release, and optionally update `CHANGELOG.md`. Use when the user says "cut a release", "tag a release", "publish a release", "ship vX.Y.Z", "bump the version", "what version should this be", "write the release notes", "draft the changelog", or invokes /release. Distinct from /gh-bootstrap (which scaffolds the `.github/release.yml` + release workflow plumbing once) and /gh (raw per-command `gh release` ops): this skill runs the actual release ceremony — version decision, notes, tag, publish. Run after the work is merged to the default branch.

release

Cuts a versioned release: pick the next semantic version, write proper release notes, tag the commit, and publish the GitHub release.

This sits next to /gh-bootstrap and /gh and answers a different question. /gh-bootstrap wires the release plumbing once (.github/release.yml, the tag-driven workflow). /gh is the raw gh release command reference. This skill is the ceremony you run each time you ship: decide the bump, draft the notes, tag, publish.

Where this skill fits

Concern	Skill
One-time release-notes config + tag-driven workflow	/gh-bootstrap
Raw per-command gh release create / view / upload	/gh
Deciding the version, drafting notes, tagging, publishing	/release (this skill)
Local commit before any of this	/plate

If the repo has a tag-driven release workflow (from /gh-bootstrap), pushing the tag is enough — the workflow publishes the release. This skill still decides the version and (optionally) drafts curated notes; it just stops after the tag push and reports that the workflow takes over. Otherwise it publishes the release itself with gh release create.

Protocol

1. Pre-flight

Refuse to release from a dirty or diverged state — a release tag is permanent and public.

git fetch --tags origin
BRANCH=$(git branch --show-current)
DEFAULT=$(gh repo view --json defaultBranchRef --jq .defaultBranchRef.name)
git diff-index --quiet HEAD || { echo "uncommitted changes — commit or stash first"; exit 1; }
[ "$BRANCH" = "$DEFAULT" ] || echo "WARNING: not on $DEFAULT (on $BRANCH) — releases normally tag the default branch"
read -r AHEAD BEHIND < <(git rev-list --left-right --count "origin/$DEFAULT...HEAD")
[ "$BEHIND" = 0 ] || { echo "HEAD is $BEHIND commits behind origin/$DEFAULT — pull/rebase before tagging"; exit 1; }
LAST_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "")

Confirm with the user:

• The commit to tag (default: tip of the default branch).
• The last release tag ($LAST_TAG) — the baseline for the version bump and the notes range. If the repo has no tags yet, this is the first release.

Stop and tell the user — don't tag — if the tree is dirty, or HEAD is behind origin/$DEFAULT.

2. Decide the version

Read references/semver.md for the full decision rules. The short version: scan the Conventional Commits since the last tag and map the highest-impact change to a bump.

git log "${LAST_TAG:+$LAST_TAG..}HEAD" --no-merges --pretty='%s'

Highest-impact change since last tag	Bump (≥ 1.0.0)	Bump (0.x pre-1.0)
feat!: / fix!: / BREAKING CHANGE: footer	major	minor
feat:	minor	patch
fix: / perf:	patch	patch
only docs / chore / refactor / test / ci	patch (or skip — ask)	patch

Match the repo's existing tag scheme — if $LAST_TAG is v1.2.3, the next is v1.3.0, not 1.3.0. Detect and reuse the v prefix (or its absence). Detect prerelease identifiers (-rc.1, -beta.2) and keep the user's convention.

Propose the computed version and the one-line reason ("3 feats, no breaking → minor → v1.3.0"). Let the user confirm or override. Never tag a version the user hasn't seen.

3. Draft the release notes

Read references/release-notes.md for the three strategies and how to choose. Summary:

• Auto-generated (gh release create --generate-notes) — best when the repo merges via PRs and has .github/release.yml. GitHub groups merged PRs into the configured category buckets by label. Cheapest, and complete as long as every change landed as a labelled PR.
• Hand-curated — best when there's no .github/release.yml, when commits (not PRs) are the unit of change, or when the release needs editorial highlights. Group by Conventional Commit type; lead with a Highlights section and, for any breaking change, an Upgrade notes section with the concrete migration step. assets/release-notes-template.md is the starting structure.
• Hybrid — generate, then hand-edit the top to add highlights and upgrade notes. The most common choice for a release that matters.

When curating, derive the entries from the commit log, not from imagination — every bullet must trace to a real commit. Link PRs/commits where the audience would want the detail.

4. Update CHANGELOG.md (if the repo keeps one)

If CHANGELOG.md exists, keep it in sync. Most repos follow Keep a Changelog: move the ## [Unreleased] entries under a new ## [VERSION] - YYYY-MM-DD heading, leave a fresh empty Unreleased, and update the comparison links at the bottom. If there's no changelog and the user doesn't want one, skip this — don't introduce a changelog they didn't ask for.

5. Tag and push

Annotated tag (carries a message, author, and date — lightweight tags don't, and git describe treats them differently). Tag the agreed commit, then push only the tag.

VERSION=v1.3.0
git tag -a "$VERSION" -m "$VERSION"        # add -s to GPG-sign if the repo signs tags
git push origin "$VERSION"

If a tag-driven release workflow exists (.github/workflows/release.yml), stop here — the workflow publishes the release on tag push. Report the workflow run URL and skip step 6.

6. Publish the GitHub release

Only when there's no tag-driven workflow doing it for you.

# Auto-generated notes:
gh release create "$VERSION" --title "$VERSION" --generate-notes --latest

# Curated notes from a file:
gh release create "$VERSION" --title "$VERSION" --notes-file NOTES.md --latest

# Prerelease (rc/beta/alpha) — do NOT mark --latest:
gh release create "$VERSION" --title "$VERSION" --notes-file NOTES.md --prerelease

# Draft for review before going public:
gh release create "$VERSION" --title "$VERSION" --notes-file NOTES.md --draft

Attach build artifacts by listing them after the tag (gh release create "$VERSION" ... dist/*.tar.gz) when the project ships binaries.

7. Verify and report

Read the published state back — don't claim success from the create command's exit code alone.

gh release view "$VERSION" --json tagName,isLatest,isDraft,isPrerelease,url --jq .
git ls-remote --tags origin "$VERSION"

Report to the user: the version and why, the notes strategy used, the release URL, and whether it's draft/prerelease/latest. Call out anything skipped (e.g. "workflow is publishing — release not yet visible") and why.

What this skill is NOT for

• Scaffolding .github/release.yml or the release workflow — that's /gh-bootstrap (run once, first).
• Looking up raw gh release flags outside a release ceremony — that's /gh.
• Committing or pushing branch code — that's /plate.
• Publishing to a package registry (npm / crates.io / PyPI). This skill tags and creates the GitHub release; registry publishing is the project's own just/CI step.
• Per-package versioning in a monorepo with independent release lines — out of scope; this skill cuts one tag for one version line. Say so if the repo is a multi-package monorepo.

Gotchas

• Never re-point an existing tag. git tag -f + git push -f to move a published tag breaks every consumer who already fetched it. If you tagged the wrong commit, cut a new patch version instead.
• Auto-generated notes only see merged PRs. Direct pushes to the default branch don't appear. A repo without PR-based merges (no branch protection) should curate notes, not rely on --generate-notes.
• --generate-notes needs .github/release.yml to group nicely; without it you get a flat "What's Changed" list. If the grouping looks wrong, the categories/labels in release.yml are the lever — fix them via /gh-bootstrap, not here.
• Prereleases must not be --latest. Marking an -rc build as latest makes it the default download and the target of releases/latest. Use --prerelease and omit --latest.
• Pre-1.0 semver is different. Under 0.x, breaking changes bump the minor, not the major. See references/semver.md.
• Tag must be an ancestor of the default branch. Tagging a feature-branch commit ships unreviewed code. Confirm the commit is on (or merged into) the default branch before tagging.
• Signed tags — if the repo signs releases (git config tag.gpgSign true or a project convention), use git tag -s; an unsigned tag on a signed-release repo fails verification downstream.
