    Changelog from Commits

    End-user changelog in plain prose from a raw git log. Filters noise (chore/refactor/ci), groups by theme, translates jargon, detects breaking changes. 4 sections + summary + social hook.

    WORKS IN
    CLAUDEany setup

    Pure-LLM skill. No MCP, no paid tool required. Works on Claude.ai web, desktop and Claude Code.

    WORKS BEST WITH
    • GitHub MCPoptional

      fetches commits + PR titles + PR descriptions straight from the repo — much better output (PR descriptions are written for humans, commits aren't)

    • Filesystemoptional

      writes straight to ./CHANGELOG.md, prepending to the right section and preserving previous releases

    What this skill does

    Takes a raw git log and generates a changelog in prose for end users. Groups by theme (not by commit), translates technical jargon, cites PRs, drops irrelevant refactors, flags breaking changes.

    What you get

    • Changelog in markdown, ready to post
    • Grouped into: New, Improvements, Fixes, Breaking
    • Each item: what changed (in user language) + PR link
    • 2-sentence summary at the top
    • A suggested hook to announce it on social

    When to use

    • On every customer-facing release
    • Monthly, as a digest for users
    • Before an investor update

    Don't use for:

    • Technical release notes for the internal team (read the git log directly)

    How it works

    1. You paste the git log between 2 tags or the last N commits
    2. The skill ignores chore, refactor and ci commits with no external impact
    3. Groups related commits (e.g. 3 commits for the same feature)
    4. Translates technical messages into product language
    5. Spots breaking changes even when they are not marked as BREAKING
    6. Returns markdown with sections and CTAs to announce it
