CLAUDE.md

skills CLAUDE.md is an instructions file for Claude Code from bmad-labs/skills. It costs 635 tokens per session, scanned C, original, MIT.

Repository instructions for a marketplace of reusable instruction packages, called skills, for AI coding agents. They explain the required SKILL.md format, repository layout, testing, and evaluation materials.

In plain words
What is it for?
Adding or updating skills, using the starter template, organizing scripts and reference files, and working with the marketplace's specifications and benchmarks.
Why use it?
They help contributors create skills that follow the marketplace's structure and can be used consistently by different coding agents.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is bmad-labs/skills's own configuration. It tells Claude Code how to work on skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skills configures →

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 C, and why

skills CLAUDE.md scanned grade C with 1 finding 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 8d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Purpose

This is the BMAD Skills Marketplace — a collection of skills for Claude Code and other AI agents (Cursor, Codex, OpenCode, etc.). Skills are self-contained instruction sets defined in SKILL.md files that extend agent capabilities.

Architecture

skills/[skill-name]/
├── SKILL.md         # Required: YAML frontmatter + instruction content
├── scripts/         # Optional: helper scripts
├── references/      # Optional: reference documentation
└── assets/          # Optional: images, resources

Key directories:

  • skills/ — all skill implementations (10+ skills)
  • template/ — starter template for new skills
  • spec/ — skills specification documentation
  • _bmad/ — BMAD workflow automation framework (roles, phases, orchestration)
  • .claude/commands/ — BMAD slash commands for Claude Code
  • books/ — source books used by book-related skills

SKILL.md Format

Every skill requires a SKILL.md with YAML frontmatter:

---
name: skill-name          # lowercase, hyphenated, unique
description: >            # Complete description of what the skill does
  and when Claude should use it. This drives auto-invocation.
---

Content guidelines: specific and actionable instructions, real examples, under 500 lines, link to scripts/docs instead of inlining large content.

Evaluations and Benchmarks

!IMPORTANT: Evaluation and benchmark results for each skill are stored in evaluations/skills/<skill-name>/:

Testing a Skill Locally

Install a skill by adding it to .claude/settings.json:

{
  "skills": ["/absolute/path/to/skills/your-skill-name"]
}

Then verify in Claude Code: ask "What skills are available?" or run /plugin.

Validating Plugin Structure

claude plugin validate .

Creating a New Skill

  1. Copy the template: cp -r template/ skills/your-skill-name/
  2. Edit SKILL.md frontmatter and content
  3. Update the skills table in README.md
  4. Test locally, then submit a PR from branch skill/your-skill-name

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.
