How do I install WordPress Plugin Dev?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use WordPress Plugin Dev with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · b78329f

Built a real 'return user preferences over REST' endpoint: the baseline PHP omitted permission_callback entirely (a well-known WP REST footgun that leaves routes effectively public), while the skill's mandatory-rules list forced it in plus proper WP_Error status codes and i18n strings.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What WordPress Plugin Dev does

Covers the full WordPress plugin lifecycle — architecture, Gutenberg blocks, REST/admin/Settings API, security, performance, release-to-WordPress.org, and compatibility with top-100 plugins/themes — via 14 topic reference files and 20+ named workflows. Triggers on plugin architecture, block.json, REST endpoints, WP-CLI, PHPUnit, Plugin Check, or WordPress.org release requests; enforces capability+nonce checks and mandatory permission_callback on every REST route it writes.
