release-notes

release-notes is a command for coding agents from sigistry/marketplace. It costs 20 tokens per session (868 once invoked), scanned A, original, MIT.

A command that turns a range of git commits into human-readable release notes grouped by common changelog sections.

In plain words
What is it for?
Use it to create a changelog from the latest release tag or another commit range, including inferred change types and breaking-change notes.
Why use it?
It can make sense of messy or non-standard commit history and highlights breaking changes with a suggested next version.

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.

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.

Turn a range of git history into human-readable release notes grouped by Keep a Changelog categories, with breaking changes called out at the top and a suggested next version. Works even when the history does NOT use Conventional Commits, it infers change types from diffs and messages. $ARGUMENTS is an optional from-ref..to-ref range.

Process

Step 1: Resolve the range

  • If $ARGUMENTS contains a .. range, use it verbatim.
  • Otherwise find the last release tag: git describe --tags --abbrev=0 and use <last-tag>..HEAD.
  • If there are no tags at all, use the full history --root..HEAD (the first release) and say so.

Print the resolved range and the tag it starts from.

Step 2: Gather the history

  • git log --no-merges --pretty=format:'%H%x09%s%x09%an%x09%ad' --date=short <range>: the commit list.
  • git log --no-merges --pretty=format:'%H%n%B%n==END==' <range>: full bodies, to mine footers and rationale.
  • For commits whose message is uninformative ("wip", "fix", "update"), read git show --stat <sha> and, if needed, git show <sha> to infer the real change type from the diff.

Step 3: Classify each commit

Map every commit to a Keep a Changelog category AND note its conventional type where inferable, per the changelog-assembly skill:

Category Signals
Added new files/exports/endpoints/flags; feat
Changed modified behavior/defaults/signatures; refactor, perf that alters behavior
Deprecated @deprecated, deprecation notices
Removed deleted exports/endpoints/flags/files
Fixed bug fixes; fix
Security vuln fixes, dependency CVE bumps, auth hardening

De-duplicate: collapse "fix typo in fix" churn, fold follow-up commits into the feature they complete. Reword terse messages into user-facing language (describe the effect, not the code).

Step 4: Detect breaking changes

Flag any BREAKING CHANGE: footer, any ! marker, and any behavioral break inferable from the diff (removed/renamed public export, changed signature/default, removed flag/env var). Consult the breaking-change-detection skill. Collect these into a prominent top section.

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.
