Audit and synchronize local agent configuration — AGENTS.md / CLAUDE.md instructions, Agent Skills, and MCP server definitions — across Claude Code, Cursor, Codex, Antigravity, Grok Bot, and Hermes with the AgentPlaybooks CLI, and back a project up to or restore it from a hosted playbook. Use only where a terminal with Node.js 20+ is available, such as Claude Code; for working with playbook contents from chat, use the playbooks skill instead.

Provide standard AI/ML task definitions as portable skills for use with major coding agents like OpenAI Codex and Claude Code.
