Teach my coding agent how WordPress works
Claude Code, Cursor and Codex write decent PHP and then get WordPress wrong: escaping, hooks, block.json. Skills fix that. They are instruction files your agent loads when the task calls for them.
-
Start here. The official set, maintained by the WordPress project, and it works with every major agent.
Official repository with 14 skills for Claude Code, Codex, Copilot, Cursor, Gemini CLI, and more. 1.2K+ stars. Install via `npx skills add`. Includes: `wordpress-router`, `wp-block-development`, `wp-plugin-development`, `wp-rest-api`, `wp-abilities-api`, `wp-performance`, `wp-playground`, and more.
-
Add this if you ship to WordPress.org. It checks coding standards, security and the directory guidelines.
Skills enforcing WordPress coding standards, security best practices, WCAG 2.1 AA accessibility, and .org directory guidelines for plugin/theme development and security review.
-
Another general set, from Automattic. Worth comparing with the official one.
General-purpose WordPress expertise skills (not theme/site-creation-specific) installable globally or per-project for Codex, VS Code, and Claude Code.
-
Give the agent somewhere to run its code. A disposable WordPress in the browser, no Docker.
One `npx` command connects agents to WordPress Playground running in the browser via WebAssembly. No server, no Docker.
-
Same idea with a real local site, if you already use Studio.
Automattic's local dev app exposes an MCP server (Settings → MCP) so agents like Claude Code and Copilot can create, start, and manage local sites, edit files, query the database, and run WP-CLI.
