changelog-generator Convert a git log, commit list, or release notes into a polished, user-facing changelog. Use when writing release notes, generating a CHANGELOG.md entry, or documenting what changed in a version. Produces a structured changelog section with version header, categorised changes, and migration notes.

Changelog Generator Skill

Converts raw git commits, a diff summary, or developer release notes into a polished changelog entry — categorised, user-facing, and following Keep a Changelog conventions.

Required Inputs

Ask for these if not provided:

  • Commits or release notes (paste git log --oneline, raw commit messages, or a description of what changed)
  • Version number (e.g. 2.4.0, v1.0.0-beta.2)
  • Release date (or "today")
  • Audience (developers using an API / end users of a product / internal team — affects language)
  • Any breaking changes (flag these explicitly if known)

Output Format

Follow Keep a Changelog format:


[X.Y.Z] — YYYY-MM-DD

Breaking Changes ⚠️

[Only include if there are breaking changes]

  • [Breaking change]: [What changed and what it breaks]
  • Migration required: [Specific action the user must take]

Added

  • [New feature or capability, written from the user's perspective]
  • [Another addition]

Changed

  • [Changed behaviour — what it did before vs. what it does now]
  • [Performance improvement with measurable impact if known]

Fixed

  • [Bug fixed — describe what was broken, not the fix implementation]
  • [Another fix]

Deprecated

  • [Deprecated thing] — use [replacement] instead. Will be removed in [version].

Removed

  • [Removed thing] — was deprecated in [version]

Security

  • [Security fix — describe the vulnerability class, not exploit details]

Formatting Rules Applied

Language: Write for the reader, not the committer. "Add dark mode support" not "implement ThemeProvider with dark palette variant".

Breaking changes: Always call these out first with ⚠️. Include a migration path.

Bug fixes: Describe what was broken, not what was changed. "Fix crash when user has no profile picture" not "null-check avatar URL before rendering".

Granularity: Group related commits into one line. Don't list every micro-commit separately.

Tone: Active voice, imperative mood. "Add", "Fix", "Remove" — not "Added", "Fixed", "Removed".

Empty sections: Omit any section with no entries. Don't include empty ### Fixed blocks.

Quality Checks

  • Breaking changes are at the top with migration instructions
  • All entries are user-facing language (no internal variable names or implementation details)
  • Related commits are grouped into single entries (not listed individually)
  • Version and date header is correct
  • Empty sections are omitted
  • Tone is imperative mood throughout

Usage Examples

  • "Write a changelog for version [X]" + [paste commits]
  • "Generate release notes from these commits"
  • "Turn this git log into a CHANGELOG entry"
  • "Write the CHANGELOG.md update for this release"
  • "What changed in this release?" + [paste commit list]
