Semantic Versioning Skill

Instructions

1. Detect Current Version

• Read the latest version from CHANGELOG.md (e.g., the most recent header ## [X.Y.Z]).
• Read the version from .github/repository-metadata.json.
• If they differ, flag the mismatch to the user and ask which is authoritative.

2. Analyze Changes

Scan the changes since the last release:

• If using changelog skill: Look at the items under [Unreleased] or the new version block being prepared.
• If using git log: Scan for Conventional Commits types.

3. Determine Increment Type

Follow these priority rules:

1. MAJOR (X.0.0): Any "BREAKING CHANGE" footer or ! after the type (e.g., feat!:).
2. MINOR (x.Y.0): Any feat commit or "Added" entry in the changelog.
3. PATCH (x.y.Z): Any fix, perf, refactor commit or "Fixed"/"Changed" entry in the changelog.
4. No Change: If only docs, chore, style, test, build, or ci changes are found, default to PATCH unless the user specifies otherwise.

4. Apply Version Update

Update the following files in a single pass:

• CHANGELOG.md: Rename the ## [Unreleased] section to ## [NEW_VERSION] - CURRENT_DATE or update the latest entry.
• .github/repository-metadata.json: Update the "version" field.

Quality Gates

• Version follows MAJOR.MINOR.PATCH format.
• No regression in version number.
• All version-tracking files are synchronized.
• Date in CHANGELOG.md is in YYYY-MM-DD format.
