WordPress（Gutenberg）ブロック開発時に使用：block.jsonメタデータ、register_block_type(_from_metadata)、属性/シリアライゼーション、サポート、動的レンダリング（render.php/render_callback）、非推奨/マイグレーション、viewScriptとviewScriptModule、@wordpress/scripts/@wordpress/create-block のビルドおよびテストワークフロー。
このスキルはWordPress（Gutenberg）ブロック開発を支援するために設計されています。開発者はblock.jsonメタデータの設定、register_block_typeやregister_block_type_from_metadataを用いたブロックの登録、属性の定義とシリアライゼーション、サポート機能（supports）の設定、動的レンダリング（render.phpまたはrender_callback）の実装、ブロックの非推奨化（deprecations）やマイグレーションの管理、viewScriptとviewScriptModuleの使い分けなど、Gutenbergブロックの標準的な開発パターンを効率的に行えます。また、@wordpress/scriptsや@wordpress/create-blockを利用したビルドやテストのワークフローもサポートします。このスキールはClaude Code、Cursor、CodexなどのAIエージェント向けに最適化されており、開発者がブロック開発のベストプラクティスに沿ってコードを記述し、バグを減らし、メンテナンス性の高いブロックを構築するのに役立ちます。

This repo contains 13 individual skills — each has its own dedicated page.
Use when creating, editing, or reviewing WordPress Playground blueprint JSON files. Triggers on mentions of blueprints, playground configuration, or requests to set up a WordPress demo environment.
Use when the user asks about WordPress codebases (plugins, themes, block themes, Gutenberg blocks, WP core checkouts) and you need to quickly classify the repo and route to the correct workflow/skill (blocks, theme.json, REST API, WP-CLI, performance, security, testing, release packaging).
Use when working with the WordPress Abilities API (wp_register_ability, wp_register_ability_category, /wp-json/wp-abilities/v1/*, @wordpress/abilities) including defining abilities, categories, meta, REST exposure, and permissions checks for clients.
Use when developing WordPress block themes: theme.json (global settings/styles), templates and template parts, patterns, style variations, and Site Editor troubleshooting (style hierarchy, overrides, caching).
Use when building UIs leveraging the WordPress Design System (WPDS) and its components, tokens, patterns, etc.
Use when building or debugging WordPress Interactivity API features (data-wp-* directives, @wordpress/interactivity store/state/actions, block viewScriptModule integration, wp_interactivity_*()) including performance, hydration, and directive behavior.
Use when investigating or improving WordPress performance (backend-only agent): profiling and measurement (WP-CLI profile/doctor, Server-Timing, Query Monitor via REST headers), database/query optimization, autoloaded options, object caching, cron, HTTP API calls, and safe verification.
Use when configuring, running, or fixing PHPStan static analysis in WordPress projects (plugins/themes/sites): phpstan.neon setup, baselines, WordPress-specific typing, and handling third-party plugin classes.
Use for WordPress Playground workflows: fast disposable WP instances in the browser or locally via @wp-playground/cli (server, run-blueprint, build-snapshot), auto-mounting plugins/themes, switching WP/PHP versions, blueprints, and debugging (Xdebug).
Use when developing WordPress plugins: architecture and hooks, activation/deactivation/uninstall, admin UI and Settings API, data storage, cron/tasks, security (nonces/capabilities/sanitization/escaping), and release packaging.
Use when you need a deterministic inspection of a WordPress repository (plugin/theme/block theme/WP core/Gutenberg/full site) including tooling/tests/version hints, and a structured JSON report to guide workflows and guardrails.
Use when building, extending, or debugging WordPress REST API endpoints/routes: register_rest_route, WP_REST_Controller/controller classes, schema/argument validation, permission_callback/authentication, response shaping, register_rest_field/register_meta, or exposing CPTs/taxonomies via show_in_rest.
Use when working with WP-CLI (wp) for WordPress operations: safe search-replace, db export/import, plugin/theme/user/content management, cron, cache flushing, multisite, and scripting/automation with wp-cli.yml.
Gemini CLI one-shot prompts, summaries, generation, skills, hooks, MCP, or Gemma routing.
Fetch GitHub issues, select candidates, spawn background fix agents, open PRs, and optionally process PR review comments.
Create, edit, audit, tidy, validate, or restructure AgentSkills and SKILL.md files.
Search, install, update, sync, or publish agent skills with the ClawHub CLI and registry.
Delegate coding work to Codex, Claude Code, or OpenCode as background workers; not simple edits or read-only code lookup.
List, configure, authenticate, call, and inspect MCP servers/tools with mcporter over HTTP or stdio.
