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.

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-skills AGENTS.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 5d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This file provides guidance to AI coding agents (Claude Code, Cursor, Copilot, Cline, etc.) when working with code in this repository.

Repository Overview

A collection of agent skills published by carofi-auto. Each skill packages domain knowledge into a format that AI coding agents can install and use automatically.

Skills are plain markdown — no build step, no dependencies.

Directory Structure

├── README.md               # skill directory and install commands
├── AGENTS.md               # this file
├── CLAUDE.md               # Claude Code-specific guidance (same content)

        └── {topic}.md

Adding a New Skill

1. Create the skill directory

Use kebab-case. The directory name becomes the --skill argument at install time.

{skill-name}/
├── SKILL.md
└── references/         # add only if SKILL.md would exceed ~400 lines without it
    └── {topic}.md

2. Write SKILL.md

Required frontmatter:

---
name: {skill-name}
description: "{One sentence written as a trigger condition — when should an agent activate this skill? Include key nouns: library names, env var names, domain terms.}"
---

Body structure (adapt sections to the skill's complexity):

# {Skill Title}

> **Attribution:** {Credit the upstream source if this skill is built on
> official documentation. Link to the source.}

Brief one-paragraph description of what this skill covers.

## When this skill activates

- Bullet list of concrete trigger signals (env vars, keywords, file patterns)

## Non-negotiable rules

Numbered list of rules the agent must enforce regardless of user intent.
Security rules, data integrity rules, and irreversibility warnings belong here.

## Before writing any integration code

Table mapping tasks to reference files (if references/ exists).

## {Any domain-specific sections}

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.
