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-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 1mo 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

Skill Review

Reviews a SKILL.md against established best practices and outputs a structured pass/fail report with prioritized recommendations.

Contents

Locating the Target Skill

With explicit path: Use the provided path directly (supports both SKILL.md files and plugin directories).

Without path — search in this order:

  1. Current directory: ./SKILL.md
  2. Plugin skill dirs: ./plugins/*/skills/*/SKILL.md
  3. Prompt the user if multiple matches found

Review Workflow

  1. Read SKILL.md and any files in references/ that it links to
  2. Run each check in references/checklist.md — assign PASS ✅, WARNING ⚠️, or ERROR ❌
  3. Output the structured report below

Be educational, not just a linter — include a brief explanation of why each finding matters.

Output Format

## Skill Review: [skill-name]

### Summary
**Status:** PASS / NEEDS WORK / FAIL
**Score:** N/N checks passed | N warnings | N errors

Severity Definitions

Severity Meaning
❌ Error Violates a spec requirement. Must fix before publishing.
⚠️ Warning Best practice violation. Should fix for quality.
✅ Pass Meets the standard.

Full Rubric

See references/checklist.md for all checks organized by category (frontmatter, description quality, naming, content, structure, scripts, plugin manifest).

Files

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.
