Composer Agent Skill Plugin

Composer AI Agent Skill Plugin

A Composer plugin for **AI agent skills** in PHP projects. Skills are **skill dependencies** of your repo: you declare them through **one or more** of the mechanisms below (they are equivalent in the sense that everything flows into the same discovery, trust, and **`AGENTS.md`** pipeline—you may **combine** them). Versioning and publishing differ (semver packages vs pinned git lock), not whether the path is “official.”

Features

• Three ways to bring skills in — see How skills enter your project: (1) composer require a type: ai-agent-skill package, (2) composer require any package that lists skills under extra.ai-agent-skill, (3) declare GitHub or in-repo paths under extra.ai-agent-skills with composer.skills.lock and composer skills … (Direct sources).
• Automatic discovery: Finds skills from installed packages (legacy type and universal extra form).
• AGENTS.md generation: Creates XML skill index compatible with openskills
• CLI commands: composer list-skills, composer read-skill, trust helpers, composer skills:* for direct sources, and composer outdated appends direct-skill rows (text) or points to **`composer skills:outdat
