Does this skill overwrite my existing changelog?

By default, the skill uses a 'Fill' mode that identifies the last documented version and only appends new entries, preserving your existing content.

Is it fast enough for large repositories?

Yes, the skill launches up to 12 parallel Haiku subagents to process different version ranges simultaneously, making it highly efficient for large histories.

What documentation standards does it follow?

It strictly adheres to the 'Keep a Changelog' format and assumes the project follows Semantic Versioning (SemVer).

Can I use this on a project without tags?

Yes, if no tags exist, the skill will process all commits into an 'Unreleased' section or a single version block.

How does it categorize commit messages?

Instead of just looking at commit prefixes, it uses AI subagents to interpret the actual change and place it in the most relevant section like Fixed, Added, or Security.

Content Management

Automates the creation and maintenance of professional project changelogs directly from Git history using AI-driven categorization.

The Changelog Generator skill streamlines project documentation by analyzing Git commits and tags to build or update your CHANGELOG.md. It utilizes parallel Claude Haiku subagents to intelligently categorize changes into standard sections like Added, Fixed, and Security, following the 'Keep a Changelog' format. Whether you are bootstrapping documentation for a legacy project or preparing release notes for a new version, this skill ensures your history is accurate, professionally formatted, and focused on user-observable impact rather than raw commit logs.
