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

agent-audit 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.

Reference Files

Advanced agent validation guidance:


Agent Auditor

Validates agent configurations for model selection, tool restrictions, focus areas, and approach methodology.

Quick Start

Basic audit workflow:

  1. Read agent file
  2. Check model selection appropriateness
  3. Validate tool restrictions
  4. Assess focus area quality
  5. Review approach methodology
  6. Generate audit report

Example usage:

User: "Audit my evaluator skill"
→ Reads skills/evaluator/SKILL.md
→ Validates model (Sonnet), tools, focus areas, approach
→ Generates report with findings and recommendations

Agent Audit Checklist

Critical Issues

Must be fixed for agent to function correctly:

  • Valid YAML frontmatter - Proper syntax, required fields present
  • name field matches filename - Name consistency
  • model field present and valid - Sonnet, Haiku, or Opus only
  • At least 3 focus areas - Minimum viable expertise definition
  • Tool restrictions present - allowed_tools or allowed-patterns specified
  • No security vulnerabilities - Tools don't expose dangerous capabilities

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
