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 1mo 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

Changelog

Update CHANGELOG.md with recent changes.

Process

  1. Read the existing CHANGELOG.md (create one if it doesn't exist)
  2. Run git log --oneline since the last changelog entry to see what changed
  3. Group changes by type and write the new entry

Format

Follow Keep a Changelog:

## [version] - YYYY-MM-DD

### Added
- New features

### Changed
- Changes to existing features

### Fixed
- Bug fixes

### Removed
- Removed features

Rules

  • Write for users, not developers. "Fixed crash when saving empty form" not "Fixed null pointer in FormHandler.save()"
  • Skip internal changes (refactors, test updates, CI tweaks) unless they affect users
  • Group related changes into one bullet. "Redesigned settings page" not five separate bullets about each settings panel.
  • Most recent version goes at the top
  • If there's no CHANGELOG.md, create one with an Unreleased section at the top
  • Link version headers to the git diff when possible: [1.2.0]: https://github.com/user/repo/compare/v1.1.0...v1.2.0
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.
