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

skill-reviewer 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 273 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Reviewer

Review a SKILL.md file for structural quality, completeness, and template compliance. Grades on 8 dimensions covering the canonical skill structure (see .claude/skills/_schema/SKILL.template.md + .claude/skills/_schema/AUTHORING.md). Used to catch drift before a skill ships.

This is a meta-skill — it reviews skill definitions, not skill outputs.


Claude Code Triggers

Invoke this skill when:

  • "review skill [name]"
  • "audit [skill-name] skill"
  • "is [skill] well-defined?"
  • "check skill quality for [skill]"
  • "grade this SKILL.md"

Do NOT invoke when:

  • User wants to review content output quality → use /voice-reviewer instead
  • User wants to check the skill catalog → use /skill-catalog instead
  • User wants to build a new skill from scratch → use prompt-design instead

Input Requirements

Required inputs

Input Description Source
SKILL.md path Path to the SKILL.md file to review User provides or inferred from context

Optional inputs (improve quality)

Input How it helps

  • SKILL.md file exists and is readable
  • File contains YAML frontmatter (between --- delimiters)

If file doesn't exist: Tell the user the path is invalid and ask for the correct one.


Process (step-by-step)

Phase 1: Read and parse

Purpose: Load the SKILL.md and extract structural elements.

Steps:

  1. Step 1.1: Read the file
    • Load the full SKILL.md content
    • Parse YAML frontmatter into key-value pairs
    • Identify all H2 (##) and H3 (###) sections present
    • Output: Parsed frontmatter + section inventory

Phase 1 checkpoint:

  • File successfully read
  • Frontmatter parsed
  • Section headers cataloged

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.
