Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00417 | $0.00417 |
| Opus 5 | $0.00209 | $0.00209 |
| Sonnet 5 | $0.00083 | $0.00083 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
agent-skills CLAUDE.md 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 2d 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
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repository Purpose
This repository contains AI agent skills and commands in two formats:
- Skills (skills.sh format): Auto-activate when relevant tasks detected, installed via
npx skills add - Claude Code Commands: Explicit invocation via
/command-name, installed by copying.claude/commands/
Repository Structure
skills/ # skills.sh format skills
<skill-name>/
SKILL.md # Instructions for the agent (frontmatter + content)
AGENTS.md # Full compiled document with all rules expanded
rules/ # Individual rule files with code examples
metadata.json # Version and reference information
.claude/commands/ # Claude Code native commands
<command-name>.md # Command file with frontmatter and instructions
Creating New Skills (skills.sh format)
Skills follow the skills.sh format:
- Create directory under
skills/<skill-name>/ SKILL.md- Main entry point with YAML frontmatter containingname,description,license, andmetadatametadata.json- Version, organization, abstract, and reference URLsrules/- Individual rule files with brief explanation + incorrect/correct code examplesAGENTS.md- Compiled document containing all rules expanded (for distribution)
Creating New Claude Code Commands
Commands are Markdown files in .claude/commands/:
- Create
.claude/commands/<command-name>.md - Add YAML frontmatter with
descriptionfield - Use
$ARGUMENTSplaceholder for user input - Include input validation and clear error messages
- Document prerequisites (e.g., required CLI tools)
Example frontmatter:
---
description: Brief description shown in command list
---
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.

agent-skills CLAUDE.md is an instructions file published in the GitHub repository arraydude/agent-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 417 tokens to every session, about $0.0021 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
