What is playbooks-cli AGENTS.md?

Repository instructions for playbooks, a command-line tool that installs reusable instruction sets for coding agents. They describe the project's structure, commands, supported agents, and installation process.

Understanding or modifying skill discovery, source parsing, agent detection, installation, Git operations, lock files, and telemetry.

They give an agent the project context needed to change the playbooks codebase consistently.

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.

Model	Per session	Once invoked
Fable 5	$0.01510	$0.01510

Security

Grade A, and why

playbooks-cli AGENTS.md scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Project Overview

playbooks is a CLI tool that installs agent skills (reusable instruction sets in SKILL.md files) onto various coding agents. It supports 23+ agents including OpenCode, Claude Code, Cursor, Codex, and more.

Usage

npx playbooks add-skill <source>          # Install a skill from GitHub, URL, or local path
npx playbooks add-skill <source> --global # Install globally for the current user

Key Concepts

Agent Configuration

Each agent is defined in src/agents.ts with:

name: CLI identifier (e.g., claude-code)
displayName: Human-readable name
skillsDir: Project-level skill directory
globalSkillsDir: User-level skill directory
detectInstalled: Function to check if agent is installed

Skill Format

Skills are directories containing a SKILL.md with YAML frontmatter:

---
name: skill-name
description: What this skill does
---

# Instructions...

Installation Modes

Symlink (default): Skills are stored in .agents/skills/<name>/ and symlinked to each agent's directory
Copy: Skills are copied directly to each agent's directory

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.
