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 9d 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

Structured code review covering security, performance, correctness, and maintainability. Works on diffs, PRs, files, or pasted code snippets.

Review Dimensions

Security

  • SQL injection, XSS, CSRF
  • Authentication and authorization flaws
  • Secrets or credentials in code
  • Insecure deserialization
  • Path traversal
  • SSRF

Performance

  • N+1 queries
  • Unnecessary memory allocations
  • Algorithmic complexity (O(n²) in hot paths)
  • Missing database indexes
  • Unbounded queries or loops
  • Resource leaks

Correctness

  • Edge cases (empty input, null, overflow)
  • Race conditions and concurrency issues
  • Error handling and propagation
  • Off-by-one errors
  • Type safety

Maintainability

  • Naming clarity
  • Single responsibility
  • Duplication
  • Test coverage
  • Documentation for non-obvious logic

Output Format

Rate each dimension and provide specific, actionable findings with file and line references. Prioritize critical issues first. Always include positive observations alongside issues.

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.
