generate-changelog

A release-note command that updates a project's CHANGELOG.md file using recent commits and merged pull requests.

In plain words
What is it for?
Use it when preparing a release to document breaking changes, features, bug fixes, documentation, and other relevant updates.
Why use it?
It removes the manual work of finding changes and organizing them into release-note sections. It also records the update as a git commit with a fixed message.

Command for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 175 The whole file, excluding the scripts and references it only reads on demand.

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

generate-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 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.

What it actually says

You are updating the changelog for the new release.

Update CHANGELOG.md to add a new section for the new version at the top of the file, right after the '# Changelog' heading.

Review the recent commits and merged pull requests since the last release to generate meaningful changelog content for the new version. Follow the existing format in CHANGELOG.md with sections like:

  • Breaking Changes (if any)
  • New Features
  • Bug Fixes
  • Documentation
  • Internal/Other changes

Include only the sections that are relevant based on the actual changes. Write clear, user-focused descriptions.

After updating CHANGELOG.md, commit the changes with the message "docs: update changelog for v{new_version}".

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.
