release-notes

A method for turning the changes between two Git references into release notes. It creates a reader-focused version and an internal changelog that follows Keep a Changelog categories and links entries to commits.

In plain words
What is it for?
Use it to document a release, prepare a deployment announcement, explain what changed between versions, or create a maintained changelog.
Why use it?
It removes the need to translate raw commit history manually into useful information for customers and internal teams. It also brings breaking changes and traceability into the release summary.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

release-notes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

release-notes

Converts commit history into two artifacts with different readers: customer-facing release notes (benefits, no commit-speak) and an internal changelog (Keep a Changelog format, every line traceable to a commit). The rule that drives everything: write for the reader who didn't make the change.

How to respond

  1. Resolve the range. Default: last tag to HEAD (git describe --tags --abbrev=0). If no tags exist, ask for a start ref or take the user's two refs. State the resolved range at the top of the output: "v1.4.0..HEAD, 37 commits, 2026-05-02 → 2026-06-10".

  2. Gather the raw material. git log <range> --no-merges --pretty='%h|%s|%an|%ad' --date=short for the commit list; git log <range> --stat only when a subject line is too vague to classify. Where the gh CLI is available and the repo uses PRs, prefer PR titles over commit subjects (gh pr list --state merged --search "merged:>={date}") — they're written closer to reader language. Don't require gh; commits alone are enough.

  3. Classify every change into Keep-a-Changelog categories plus one local bucket:

    • Added / Changed / Fixed / Deprecated / Removed / Security — reader-visible
    • Internal — refactors, CI, deps, tests; appears in the internal changelog, never in customer notes
    • Needs review — can't tell what it does from the commit; goes in a list for the user, never guessed into customer notes
  4. Hoist breaking changes and migrations to the top of both artifacts, each with an Action required line. A breaking change buried under "Changed" is the cardinal failure of release notes. Detect via BREAKING, !: conventional-commit markers, migration files, major dependency bumps, and removed public API — and say which signal triggered the flag.

  5. Rewrite, don't transcribe. Each customer-facing line states what the reader can now do or no longer suffers. ✅ "Fixed a crash when exporting reports with more than 10,000 rows" — ❌ "fix NPE in ReportExporter.flush()". Drop ticket numbers and author names from customer notes; keep both in the internal changelog with the short hash on every line.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
