Overview

What it does

This skill reads Git commit history and turns it into changelogs or release notes for users. It groups changes from a specified period or between versions into new features, improvements, bug fixes, breaking changes, and security updates. It rewrites developer terminology in language users can understand and leaves out internal work such as code refactoring and tests. It can also follow your own formatting and style guidelines.

When it helps

Use it when preparing a new version for release or writing weekly or monthly product updates. It also helps draft app store update descriptions, internal release documents, and content for a public changelog page.

Example requests

  • “Create a changelog from commits since the last release.”
  • “Summarize the past seven days of changes for users.”
  • “Organize changes since v2.4.0 using the guidelines in CHANGELOG_STYLE.md.”

Notes

Use it from the root of the project's Git repository. Specify a period or target versions to narrow the scope. Reviewing and adjusting the generated content before publishing is recommended. You can save the output to CHANGELOG.md.
