release-notes-writer

release-notes-writer is a skill for Claude Code, Codex from JayRHa/AgentSkills. It costs 103 tokens per session (1,568 once invoked), scanned A, original, MIT.

A writing workflow that turns pull requests, commit messages, and changelog fragments into release notes for software users. It groups changes into features, improvements, bug fixes, and breaking changes, meaning updates that may require user action.

In plain words
What is it for?
Use it to draft release notes, update a changelog, summarize a version, categorize merged work, and write migration guidance for breaking changes.
Why use it?
It translates internal engineering records into a clear account of what changed and whether users need to adapt. It also helps surface upgrade instructions when a change can break existing use.

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-writer 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/parse_commits.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Release Notes Writer

Overview

This skill turns raw engineering output — merged PRs, commit messages, issue references, and changelog fragments — into release notes that a real user can read and act on. It enforces a consistent structure, a user-facing voice (benefit first, not implementation detail), correct categorization (especially surfacing breaking changes), and an upgrade/migration section when needed.

Keywords: release notes, changelog, CHANGELOG.md, version bump, breaking changes, migration guide, semver, what's new, release announcement, GitHub release, conventional commits.

Use this skill whenever the user has a set of changes (any of: PR titles, git log output, conventional-commit messages, a list of Jira/GitHub issues, or an existing draft) and wants them shaped into publishable notes.

When NOT to use

  • A single trivial change with no user impact — just describe it.
  • Internal-only commit summaries with no audience — use a plain commit log.
  • Writing the code itself — this skill writes the notes, not the changes.

Inputs to gather first

Before drafting, confirm or infer:

  1. Version & date — e.g. v2.4.0, 2026-06-08. Infer semver bump from the changes (see references/categorization.md).
  2. Audience — end users, API consumers/developers, or internal team. This changes vocabulary and depth.
  3. Source material — PR list, commit log, or changelog fragments.
  4. Format target — Markdown CHANGELOG.md (Keep a Changelog style), a GitHub Release body, a blog-style announcement, or in-app "What's New". If any are missing, ask once, concisely. Do not block on perfect input — infer sensible defaults and state your assumptions.

Workflow

  1. Collect changes. If given a git range, run the helper: python scripts/parse_commits.py --range v2.3.0..HEAD (or pipe git log). It parses conventional commits, groups them, and flags !/BREAKING CHANGE as breaking. Review its output — never publish it raw.
  2. Filter noise. Drop chore/ci/build/refactor/test/docs commits that have zero user impact. Merge duplicates and revert+reland pairs. Keep anything a user can see, feel, or must react to.
  3. Categorize every surviving change into exactly one of: Breaking Changes, Features (✨ new), Improvements (⚡ enhancements/perf/UX), Bug Fixes (🐛), Deprecations, Security. Use the decision table in references/categorization.md.
  4. Rewrite each line into the user-facing voice: lead with the benefit/outcome, present tense, active voice, no internal jargon, no PR/branch names in prose. Append issue/PR references in parentheses. See the rewrite patterns below and references/style-guide.md.
  5. Determine the version bump from the highest-severity category present (breaking → major, feature → minor, fix-only → patch). State it.
  6. Write the Breaking Changes + Migration section first if any exist — this is the highest-value content. Give before/after and concrete migration steps.
  7. Assemble using templates/changelog-entry.md (for CHANGELOG.md) or templates/github-release.md (for a release body). Add a one-line highlight summary at the top.
  8. Self-check against references/checklist.md. Verify ordering (Breaking → Security → Features → Improvements → Fixes → Deprecations), no empty sections, every breaking change has migration guidance, and links resolve.

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.
