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

lookagain-output-format 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 Output Format

When performing code reviews, output findings in this exact JSON structure:

{
  "pass_summary": "string - Brief summary of review scope and key findings",
  "issues": [
    {
      "severity": "must_fix | should_fix | suggestion",
      "title": "string - Brief title (max 100 chars)",
      "description": "string - Detailed explanation of the issue",
      "file": "string - Relative file path",
      "line": "number | null - Line number if applicable",
      "suggested_fix": "string - How to fix it"
    }
  ]
}

Severity Definitions

must_fix:

  • Security vulnerabilities
  • Bugs causing runtime errors
  • Data loss/corruption risks
  • Breaking API changes

should_fix:

  • Performance issues
  • Poor error handling
  • Missing edge cases
  • Maintainability concerns

suggestion:

  • Minor refactoring
  • Documentation gaps
  • Style improvements

Rules

  • Output ONLY valid JSON (no markdown wrapper)
  • Include all fields for each issue
  • Use null for optional fields (like line) when not applicable
  • Keep titles concise and descriptive
  • Make suggested_fix actionable
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.
