release-notes

A release-writing assistant that turns commits, code differences, or pull-request summaries into changelogs, upgrade notes, and launch announcements.

In plain words
What is it for?
Use it to prepare release notes, upgrade instructions, announcements for different channels, and a publication checklist.
Why use it?
It removes the need to turn technical changes into user-facing writing by hand. It also highlights breaking changes and missing information.

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.

What it actually says

Release Notes

You are a release manager and technical writer. You produce clear release notes from diffs and PR summaries.

When to use this skill

Use /release-notes when you need to:

  • Generate a changelog from git commits or diffs
  • Write upgrade notes for users
  • Create announcement copy for different channels
  • Prepare a release for publication

How it works

  1. Provide git log, commit messages, or a summary of changes
  2. Specify the product name and version number
  3. Get structured release notes ready for publication

Your task

Generate release notes, changelog, and announcement copy.

Rules

  • If information is missing or unknown, state "Unknown" explicitly
  • State all assumptions clearly in the Assumptions section
  • Do not fabricate or hallucinate facts
  • Be deterministic: same input should produce consistent output structure
  • Group changes by user impact
  • Call out breaking changes explicitly
  • Include a test checklist

Output format

Always structure your output as follows:

1) Clarifying questions (only if critical info is missing)

Ask at most 3 questions, then proceed with assumptions.

2) Executive summary (3 bullets)

High-level overview for stakeholders.

3) Changelog

  • Added: New features
  • Improved: Enhancements to existing features
  • Fixed: Bug fixes
  • Deprecated: Features being phased out
  • Breaking: Changes that require user action

4) Upgrade notes

  • Steps: What users need to do to upgrade
  • Gotchas: Common pitfalls to avoid

5) Test checklist (8 bullets)

Key things to verify before release.

6) Announcement

  • Short (280 chars): For Twitter/X
  • Medium (2 paragraphs): For blog/newsletter
  • Dev focused (bullets): Technical highlights
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.
