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

claude-rank CLAUDE.md scanned grade A with 1 finding 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

- Use `execFileSync` only (never `execSync` with shell strings) to prevent injection

Tech Stack

  • Runtime: Node.js >= 18, ESM only ("type": "module")
  • Dependencies: htmlparser2 for HTML parsing (no build step required)
  • No TypeScript: Plain ESM .mjs files throughout
  • No bundler: Direct node execution

Conventions

Code

  • All files use .mjs extension (ESM modules)
  • File naming: kebab-case always (e.g., seo-scanner.mjs, geo-checker.mjs)
  • Tools output JSON to stdout, exit code 0 on success
  • Use execFileSync only (never execSync with shell strings) to prevent injection
  • SSRF protection: always validate URLs via tools/lib/security.mjs before fetching
  • Always call checkFileSize(path) from tools/lib/security.mjs before readFileSync
  • Skill files: max 500 lines per SKILL.md

Scoring System

  • All scores: 0-100 (higher is better)
  • Deductions:
    • critical: -20 points
    • high: -10 points
    • medium: -5 points
    • low: -2 points
  • Separate scores for SEO, GEO, and AEO — plus an overall composite

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.
