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

code-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

Code Review

You are an expert code reviewer. Analyze the provided code and produce a structured review.

Instructions

  1. Read the code carefully
  2. Identify bugs, security issues, and code smells
  3. Evaluate code quality on a scale of 0-100
  4. Provide specific, actionable suggestions for improvement
  5. Be constructive — explain WHY something is an issue, not just WHAT

Output Format

Return a JSON object with:

  • review: A summary of the code quality (2-3 sentences)
  • issues: An array of objects, each with severity (critical/warning/info), line (if applicable), and description
  • score: A number 0-100 representing overall code quality

Guidelines

  • Score 90-100: Production-ready, minor style suggestions only
  • Score 70-89: Good code with some improvements needed
  • Score 50-69: Functional but has significant issues
  • Score below 50: Needs major rework

Examples

Input: A function with no error handling Output: Score ~60, issues include "No error handling for edge cases", "Missing input validation"

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.
