changelog is a skill for Claude Code from KhaledSaeed18/dotclaude. It costs 67 tokens per session (1,112 once invoked), scanned A, original, MIT.

A release-notes generator that reads Git history between releases and groups shipped changes. A changelog is a user-facing record of what changed in each release.

In plain words
What is it for?
Use it when preparing release notes or updating a changelog. It follows an existing changelog format and includes issue or pull-request links when they are present in the history.
Why use it?
It turns technical commit history into notes that users and integrators can understand, while highlighting breaking changes that may require action.

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

changelog 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 7d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Produce a changelog from what actually shipped: the commits, merged PRs, and references between two points in history. Write it for the people who read releases (users, integrators), not as a raw git log dump.

Hard rules: never break these

  • Base it on real history, never invent. Every entry must trace to a commit, PR, or issue. No speculative or aspirational items.
  • Match the existing format. If CHANGELOG.md or a changelog tool already exists, follow its structure, headings, and conventions exactly. Don't impose a new style on an established file.
  • Never rewrite already-released sections. Add the new version on top; leave shipped entries untouched.
  • Write for humans. Translate commits into user-facing outcomes. Drop pure-noise commits (formatting, CI tweaks, internal refactors) unless they affect users.
  • Surface breaking changes prominently. They're the entries most likely to ruin someone's day if missed.

Step 1: Determine the range

  • Last release to now: git describe --tags --abbrev=0 gives the latest tag; the range is <lastTag>..HEAD.
  • Between two releases: <olderTag>..<newerTag>.
  • First release ever: use the full history (no lower bound).
  • Honor an explicit range or version the user passed.

Step 2: Gather the raw material

  • Commits in range: git log <range> --no-merges --pretty=format:'%H %s' (and %b for bodies, to catch BREAKING CHANGE: footers).
  • Merge commits / PR numbers: git log <range> --merges and (#123) references in subjects.
  • Parse Conventional Commit prefixes (feat, fix, perf, refactor, docs, etc.), scopes, the ! breaking marker, and issue/ticket references (#123, JIRA-456, CU-abc).
  • Capture authors if the project credits contributors.

Step 3: Detect the project's convention

Look before you write; adopt what's already in use:

  • An existing CHANGELOG.md / CHANGES/HISTORY file → mirror its format (most follow Keep a Changelog).
  • Tooling config that owns the changelog, e.g. conventional-changelog/standard-version, release-please, changesets (.changeset/), git-cliff (cliff.toml), towncrier (newsfragments/), auto, semantic-release. If one is configured, prefer driving it over hand-writing, and explain how to run it.

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.
