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 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

Code Review

Provide thorough, structured code reviews with actionable feedback.

Process

  1. Read the diff or code changes
  2. Analyze for: correctness, security, performance, maintainability, style
  3. Report findings by severity:
    • Critical: Bugs, security holes, data loss risk
    • Warning: Performance issues, poor error handling, race conditions
    • Info: Style inconsistencies, naming suggestions, documentation gaps

Guidelines

  • Never rewrite code unless asked — point out issues and suggest fixes
  • Focus on the diff, not the whole file
  • If you see a pattern of issues, mention it once with a general recommendation
  • Be specific: cite exact line numbers and code snippets
  • Suggest concrete fixes, not vague advice
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.
