Agent Skills: release

Arguments

$ARGUMENTS - Optional: version specifier (patch, minor, major, or explicit X.Y.Z)

Flags

Parse from $ARGUMENTS:

• --dry-run: Show what would happen without making changes
• --no-push: Commit and tag locally, don't push
• --force: Skip branch check
• --yes: Non-interactive mode (skip prompts)

Process

1. Find Git Root

git rev-parse --show-toplevel

Error if not in a git repo. All operations happen from git root.

2. Detect Version File

Check in order (first match wins):

• package.json → .version
• Cargo.toml → [package].version
• pyproject.toml → [project].version or [tool.poetry].version
• version.txt → entire content (strict: exactly X.Y.Z)
• VERSION → entire content (strict: exactly X.Y.Z)

Error if multiple found. List them and abort.

3. Detect Package Manager (package.json only)

Check lockfiles:

• bun.lockb → bun
• pnpm-lock.yaml → pnpm
• yarn.lock → yarn
• package-lock.json → npm

Error if multiple lockfiles. Default to npm if none.

4. Pre-flight Checks

Abort if:

• Working tree dirty: "Uncommitted changes. Commit or stash first."
• Tag vX.Y.Z exists: "Tag vX.Y.Z already exists."
• Not on main/master: Warn and prompt (error if --yes without --force)
• Pre-release suffix in version: "Pre-release versions not supported."
• Multiple version files, lockfiles, or Python lockfiles

5. Determine Version

Parse current version (strict semver MAJOR.MINOR.PATCH):

• No arg or patch: increment PATCH
• minor: increment MINOR, reset PATCH
• major: increment MAJOR, reset MINOR and PATCH
• Explicit X.Y.Z: validate greater than current

6. Run Pre-release Checks

Hard abort if checks fail.

| Project | Command | |---------|---------| | package.json | <pm> run check or <pm> run test (first found) | | Cargo.toml | cargo test | | pyproject.toml | pytest |

7. Update Version

Edit version file with new version.

8. Commit, Tag, Push

git add <version-file> [<lockfile-if-changed>]
git commit -m "chore: release vX.Y.Z"
git tag vX.Y.Z
git push && git push --tags

Skip push if --no-push. Use default remote for current branch.

9. Output

Released vX.Y.Z
  Commit: <hash>
  Tag: vX.Y.Z
  Previous: vX.Y.Z

Dry Run

If --dry-run, show:

• Version change: 0.1.0 → 0.2.0
• Files to modify
• Commands that would run
• Then exit without changes

Error Recovery

If push succeeds but tag push fails:

Error: Failed to push tags.
The commit was pushed but the tag was not.
To recover manually:
  git push --tags

Lockfiles to Include

| Project | Lockfile | |---------|----------| | package.json | Detected lockfile (error if multiple) | | Cargo.toml | Cargo.lock | | pyproject.toml | poetry.lock, pdm.lock, or uv.lock (error if multiple) |

Don't run install/lock commands - just commit if changed.
