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 1 finding 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 409 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Changelog Management

Changelogs are the primary way users understand what changed between versions. A good changelog builds trust, reduces support tickets, and makes upgrade decisions easier. This skill covers the full lifecycle: format, generation, automation, and maintenance.

Every version entry in a Keep a Changelog file requires a comparison link at the bottom of the file. This is the most commonly forgotten element and breaks the linkability that makes changelogs useful. Always include them:

[Unreleased]: https://github.com/org/repo/compare/v1.2.0...HEAD
[1.2.0]: https://github.com/org/repo/compare/v1.1.0...v1.2.0
[1.1.0]: https://github.com/org/repo/releases/tag/v1.1.0

When adding a new version entry, update both the new version's link AND the [Unreleased] link to point to the new tag.

Changelog Overview

The recommended approach combines Keep a Changelog format with semantic-release for automation. This pairing works because Keep a Changelog is human-readable and widely recognized, while semantic-release eliminates manual version management:

  • Automatic Generation: Changelog generated from git commits via conventional commit messages
  • Version Bumping: Automatic semver versioning based on commit types (feat → minor, fix → patch)
  • Release Notes: GitHub releases populated automatically
  • Breaking Changes: Highlighted prominently with migration guidance
  • Categorized Changes: Features, fixes, and other changes grouped logically

Changelog Format

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.
