ai-agent-skills AGENTS.md

Repository instructions for a collection of AI-agent skills, which are structured guides that tell coding agents how to perform tasks. They describe the repository layout and rules for reading, adding, editing, and testing skills.

In plain words
What is it for?
Working on skill files, adding new skills, understanding the repository structure, and validating skill behavior.
Why use it?
They help agents change the intended skill only, follow the required template, and check whether a skill works in a real session.

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

ai-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 yesterday.

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

AI Agent Instructions for This Repository

This repository contains AI agent skills — structured markdown skill files for production-grade AI-assisted development.

When Working in This Repository

  • Reading skills: Skills are in skills/<name>/SKILL.md. Read the full SKILL.md before making any edits.
  • Adding skills: Follow the template in docs/skill-template.md exactly. Every section is required.
  • Editing skills: Only edit the skill you're asked to change. Don't refactor adjacent skills.
  • Testing skills: Test by applying the skill to a real agent session and verifying the output quality.

Repository Structure

skills/          ← All 30 skill files (SKILL.md per directory)
agents/          ← Specialist agent persona definitions
references/      ← Supporting checklists (security, performance, etc.)
docs/            ← Setup guides, skill anatomy, template
.claude/         ← Claude Code slash commands
.gemini/         ← Gemini CLI commands
.github/         ← GitHub Actions workflows
docs/            ← GitHub Pages site (index.html)

Key Principles

  1. Skills are workflows, not prose — agents follow steps, not skim docs
  2. Every step has a verification gate — "seems right" is never sufficient
  3. Skills include anti-rationalization tables — common excuses + rebuttals
  4. Skills are minimal — only what's needed to guide the agent through the task

When Adding a New Skill

  1. Create directory skills/<kebab-name>/
  2. Create SKILL.md using the template from docs/skill-template.md
  3. Add to skills/index.json for the GitHub Pages search to pick it up
  4. Update README.md skills table

Validation

Before a skill is merged:

  • Applied to at least one real agent session
  • All sections filled (no "TODO" or empty sections)
  • Verification criteria are concrete (not "make sure it works")
  • Anti-rationalization table has at least 3 entries
  • Added to skills/index.json
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.
