Keep a Changelog Assistant

This skill helps keep CHANGELOG.md accurate, current, and user-focused following Keep a Changelog format.

It is intended for maintaining changelog entries as the product evolves.
The agent helps update ## [Unreleased] and, when explicitly asked, prepare version sections in the changelog.
The human remains responsible for deciding when and how to cut a release.

Use this skill when

• The user explicitly asks to update or maintain CHANGELOG.md
• The user provides changes and wants them added to ## [Unreleased]
• The repository changes imply that CHANGELOG.md should be updated
• The user wants help categorizing changes into Added, Changed, Deprecated, Removed, Fixed, Security
• The user wants to turn accumulated Unreleased notes into a versioned changelog section

Do not use this skill when

• There is no CHANGELOG.md
