Teach AI coding assistants how to build WordPress the right way.

Agent Skills are portable bundles of instructions, checklists, and scripts that help AI assistants (Claude, Copilot, Codex, Cursor, etc.) understand WordPress development patterns, avoid common mistakes, and follow best practices.

Why Agent Skills?

AI coding assistants are powerful, but they often:

• Generate outdated WordPress patterns (pre-Gutenberg, pre-block themes)
• Miss critical security considerations in plugin development
• Skip proper block deprecations, causing "Invalid block" errors
• Ignore existing tooling in your repo

Agent Skills solve this by giving AI assistants expert-level WordPress knowledge in a format they can actually use.

Available Skills

Skill	What it teaches
wordpress-router	Classifies WordPress repos and routes to the right workflow
wp-project-triage	Detects project type, tooling, and versions automatically

wp-block-themes	Block themes: theme.json, templates, patterns, style variations
wp-plugin-development	Plugin architecture, hooks, settings API, security
wp-rest-api	REST API routes/endpoints, schema, auth, and response shaping
wp-interactivity-api	Frontend interactivity with data-wp-* directives and stores
wp-abilities-api	Capability-based permissions and REST API authentication

Quick Start

Install globally for Claude Code

# Clone agent-skills
git clone https://github.com/WordPress/agent-skills.git
cd agent-skills

# Build the distribution
node shared/scripts/skillpack-build.mjs --clean

# Install all skills globally (available across all projects)
node shared/scripts/skillpack-install.mjs --global

# Or install specific skills only
node shared/scripts/skillpack-install.mjs --global --skills=wp-playground,wp-block-development

This installs skills to ~/.claude/skills/ where Claude Code will automatically discover them.

Install into your repo

# Clone agent-skills
git clone https://github.com/Automattic/agent-skills.git
cd agent-skills

# Build the distribution
node shared/scripts/skillpack-build.mjs --clean

# Install into your WordPress project
node shared/scripts/skillpack-install.mjs --dest=../your-wp-project --targets=codex,vscode,claude

This copies skills into:

• .codex/skills/ for OpenAI Codex
• .github/skills/ for VS Code / GitHub Copilot
• .claude/skills/ for Claude Code (project-level)

Available options

# List available skills
node shared/scripts/skillpack-install.mjs --list

# Dry run (preview without installing)
node shared/scripts/skillpack-install.mjs --global --dry-run

# Install specific skills to a project
node shared/scripts/skillpack-install.mjs --dest=../my-repo --targets=claude --skills=wp-wpcli-and-ops

Manual installation

Copy any skill folder from skills/ into your project's instructions directory for your AI assistant.

How It Works

Each skill contains:

skills/wp-block-development/
├── SKILL.md              # Main instructions (when to use, procedure, verification)
├── references/           # Deep-dive docs on specific topics
│   ├── block-json.md
│   ├── deprecations.md
│   └── ...
└── scripts/              # Deterministic helpers (detection, validation)
    └── list_blocks.mjs

When you ask your AI assistant to work on WordPress code, it reads these skills and follows the documented procedures rather than guessing.

Compatibility

• WordPress 6.9+ (PHP 7.2.24+)
• Works with any AI assistant that supports project-level instructions

Contributing

We welcome contributions! This project is a great way to share your WordPress expertise—you don't need to be a coding wizard. Most skills are written in Markdown, focusing on clear procedures and best practices.
