Agent Skills for WordPress
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.
AI Authorship Disclosure: These skills were generated using GPT-5.2 Codex (High Reasoning) from official Gutenberg and WordPress documentation, then reviewed and edited by WordPress contributors. We tested skills with AI assistants and iterated based on results. This is v1, and skills will improve as the community uses them and contributes fixes. See docs/ai-authorship.md for details. (WordPress AI Guidelines)
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- Generate outdated WordPress patterns (pre-Gutenberg, pre-block themes)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.

How It Works
Each skill is a self-contained folder with instructions, references, and optional scripts:
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.
Global vs. Project Scope
Skills can be installed in two scopes:
Global — installed in your home directory (e.g. ~/.claude/skills/, ~/.cursor/skills/).
- Available across all your projects automatically.
- Best for individual developers who want WordPress knowledge in every repo.
Project — installed inside a repository (e.g. .claude/skills/, .github/skills/, .cursor/skills/).
- Available only within that specific project.
- Can be committed to version control so the entire team benefits.
You can use both at the same time. When a skill exists in both scopes, the project-level version is used.
Quick Start
The fastest way to install a skill is with a single command:
npx skills add WordPress/agent-skills --skill wp-plugin-development
To see all available skills:
npx skills add WordPress/agent-skills --list
To install multiple skills at once:
npx skills add WordPress/agent-skills --skill wp-plugin-development wp-abilities-api wp-playground
Choosing a scope
npx skills add asks to choose the skill project-scoped, selecting the local scope on which the skills are installed in the local project; it can be stored at the repository (e.g. .claude/skills/, .cursor/skills/) — so the skills can be committed to version control and shared with your team.
Installing globally makes the skill available to your user (across all your projects). Adding the -g / --global flag, it will install your skill with global scope:
npx skills add WordPress/agent-skills --skill wp-plugin-development --global
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/WordPress/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,cursor
This copies skills into:
.codex/skills/ for OpenAI Codex.github/skills/ for VS Code / GitHub Copilot.claude/skills/ for Claude Code (project-level).cursor/skills/ for Cursor (project-level)
Antigravity is opt-in for project-level installs. To also copy skills into .agents/skills/, include antigravity when building and installing:
node shared/scripts/skillpack-build.mjs --clean --targets=codex,vscode,claude,cursor,antigravity
node shared/scripts/skillpack-install.mjs --dest=../your-wp-project --targets=codex,vscode,claude,cursor,antigravity
Install globally for Cursor
node shared/scripts/skillpack-install.mjs --targets=cursor-global
This installs skills to ~/.cursor/skills/ where Cursor will discover them.
Install globally for Antigravity
node shared/scripts/skillpack-build.mjs --clean --targets=antigravity
node shared/scripts/skillpack-install.mjs --targets=antigravity-global
This installs skills to ~/.gemini/antigravity/skills/ where Antigravity will discover them.
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 (e.g. Claude + Cursor)
node shared/scripts/skillpack-install.mjs --dest=../my-repo --targets=claude,cursor --skills=wp-wpcli-and-ops
Manual installation
Copy any skill folder from skills/ into your project's instructions directory for your AI assistant.
Compatibility
- WordPress 7.0+ (PHP 7.4.0+)
- 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.
See CONTRIBUTING.md for details on how to get started.
