release-notes

release-notes is a skill for Claude Code, Codex from srnichols/plan-forge. It costs 31 tokens per session (893 once invoked), scanned A, original, MIT.

A tool for turning Git history and a CHANGELOG into release notes. It groups conventional commits, such as `feat` for features and `fix` for bug fixes, into formats for GitHub, Slack, or email.

In plain words
What is it for?
Use it before tagging a release to compare commits with the last Git tag, check the CHANGELOG, and prepare a structured summary.
Why use it?
It removes the manual work of finding what changed since the last version and organizing those changes for readers.

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 yesterday.

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.

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Release Notes Skill

Trigger

"Generate release notes" / "Prepare release" / "What changed since last release?"

Steps

1. Identify Release Range

# Find the last tag
git describe --tags --abbrev=0

# List commits since last tag
git log $(git describe --tags --abbrev=0)..HEAD --oneline --no-merges

Conditional: No Tags Found

If no tags found → ask user for the commit range to use.

2. Categorize Changes

Parse commit messages using conventional commit prefixes:

Prefix Category Show In Notes
feat New Features ✅ Always
fix Bug Fixes ✅ Always
perf Performance ✅ Always
docs Documentation ✅ If significant
refactor Internal ⚠️ Only if user-visible
test Tests ❌ Skip
chore Maintenance ❌ Skip
ci CI/CD ❌ Skip

3. Check CHANGELOG

Read CHANGELOG.md for additional context:

  • Are there entries not yet in the CHANGELOG?
  • Does the CHANGELOG match the git history?

4. Generate Release Notes

Format for GitHub Release:

## What's New

### Features
- **Feature name**: brief description (#PR)

### Bug Fixes
- Fix description (#PR)

### Performance
- Improvement description (#PR)

## Breaking Changes
- (list any breaking changes with migration steps)

## Contributors
- @username (N commits)

5. Verify

  • All features from this release are listed
  • No unreleased features included
  • Breaking changes have migration instructions
  • Commit references are correct

Safety Rules

  • NEVER fabricate changes not in the git log
  • ALWAYS flag breaking changes prominently
  • Include migration steps for any breaking change
  • Ask for human review before publishing

Temper Guards

Shortcut Why It Breaks
"The commit messages are good enough" Commit messages are for developers. Release notes are for users — different audience, different detail level.
"Nobody reads release notes" Users, support teams, and auditors rely on release notes. Missing notes cause support tickets and compliance gaps.
"I'll write them after release" Post-release notes are always incomplete. Context fades fast — write them while the work is fresh.

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.
