apply-semantic-versioning

Determine and apply the correct semantic version bump by analyzing changes since the last release. This skill reads version files, classifies changes as breaking (major), feature (minor), or fix (patch), computes the new version number, and updates the appropriate files. Follows SemVer 2.0.0 specification.

Locate and read the version file in the project root.

Parse the current version into major.minor.patch components. If the version contains a pre-release suffix (e.g., 1.2.0-beta.1), note it separately.

Apply semantic versioning (SemVer 2.0.0) to determine the correct version bump based on change analysis. Covers major/minor/patch classification, pre-release identifiers, build metadata, and breaking change detection. Use when preparing a new release to determine the correct version number, after merging changes before tagging, evaluating whether a change constitutes a breaking change, adding pre-release identifiers, or resolving disagreement about what version bump is appropriate.
