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 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- Generate outdated WordPress patterns (pre-Gutenberg, pre-block themes)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.
| 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-development | Gutenberg blocks: block.json, attributes, rendering, deprecations |
| 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 |
| wp-wpcli-and-ops | WP-CLI commands, automation, multisite, search-replace |
| wp-performance | Profiling, caching, database optimization, Server-Timing |
| wp-phpstan | PHPStan static analysis for WordPress projects (config, baselines, WP-specific typing) |
| wp-playground | WordPress Playground for instant local environments |
| wpds | WordPress Design System |
# 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 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-developmentThis installs skills to ~/.claude/skills/ where Claude Code will automatically discover them.

# 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,claudeThis copies skills into:
.codex/skills/for OpenAI Codex.github/skills/for VS Code / GitHub Copilot.claude/skills/for Claude Code (project-level)
# 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-opsCopy any skill folder from skills/ into your project's instructions directory for your AI assistant.
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.
- WordPress 6.9+ (PHP 7.2.24+)
- Works with any AI assistant that supports project-level instructions
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.
