Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 233 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

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 3d 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.

What it actually says

Generate changelog

Generate a changelog for version $ARGUMENTS by analyzing git history.

Steps

  1. Find the previous version tag using git describe --tags --abbrev=0 HEAD^ or git tag --sort=-version:refname
  2. Get all commits since that tag: git log {previous_tag}..HEAD --oneline
  3. For each commit, read the message and categorize it

Categories

Group changes into these sections (omit empty sections):

  • New Features - New functionality added
  • Bug Fixes - Issues resolved
  • Improvements - Enhancements to existing features
  • Internal - Refactoring, dependency updates, CI changes

Output format

## What's New in v{VERSION}

### New Features
- Description of feature (#PR if available)

Present the changelog to the user for review. If they approve, offer to copy it for use in a GitHub Release description.

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.
