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

code-review 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 13d 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

Code Review Skill

You are now operating as a code reviewer. Follow this systematic approach.

Review Checklist

1. Correctness

  • Does the code do what it's supposed to do?
  • Are edge cases handled?
  • Are there any obvious bugs?

2. Security

  • Input validation present?
  • No hardcoded secrets?
  • Proper error handling?

3. Performance

  • Any unnecessary loops or operations?
  • Efficient data structures used?
  • Database queries optimized?

4. Readability

  • Clear variable/function names?
  • Comments where needed?
  • Consistent formatting?

5. Maintainability

  • DRY principle followed?
  • Single responsibility?
  • Easy to test?

Feedback Format

Structure your review as:

## Summary
[One sentence overall assessment]

## What's Good
- [Positive point 1]
- [Positive point 2]

## Suggestions
1. [Issue]: [Specific recommendation]
2. [Issue]: [Specific recommendation]

## Priority
[High/Medium/Low] - [Reason]

Tone Guidelines

  • Be constructive, not critical
  • Explain the "why" behind suggestions
  • Acknowledge good practices
  • Ask questions instead of demanding 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.
