TYPO3 CKEditor 5 Development Skill\n\nExpert patterns for CKEditor 5 integration in TYPO3, including custom plugin development, configuration, and migration from CKEditor 4.\n\n## 🔌 Compatibility\n\nThis is an **Agent Skill** following the [open standard](https://agentskills.io) originally developed by Anthropic and released for cross-platform use.\n\n**Supported Platforms:**\n- ✅ Claude Code (Anthropic)\n- ✅ Cursor\n- ✅ GitHub Copilot\n- ✅ Other skills-compatible AI agents\n\n\u003e Skills are portable packages of procedural knowledge that work across any AI agent supporting the Agent Skills specification.\n\n\n## Features\n\n- **CKEditor 5 Architecture**: Plugin system, schema and conversion system, command pattern implementation, UI component development\n- **TYPO3 Integration**: RTE configuration (YAML), custom plugin registration, content element integration, backend module integration\n- **Migration Patterns**: CKEditor 4 to 5 migration, custom plugin conversion, configuration transformation, data migration strategies\n- **Plugin Development**: Complete patterns for creating custom CKEditor 5 plugins with schema definitions, converters, and commands\n- **Configuration Management**: YAML-based RTE presets with toolbar, heading, table, and link configurations\n- **ES6 Module Development**: Modern JavaScript patterns for CKEditor 5 plugin architecture\n\n## Installation\n\n### Marketplace (Recommended)\n\nAdd the [Netresearch marketplace](https://github.com/netresearch/claude-code-marketplace) once, then browse and install skills:\n\n```bash\n# Claude Code\n/plugin marketplace add netresearch/claude-code-marketplace\n```\n\n### npx ([skills.sh](https://skills.sh))\n\nInstall with any [Agent Skills](https://agentskills.io)-compatible agent:\n\n```bash\nnpx skills add https://github.com/netresearch/typo3-ckeditor5-skill --skill typo3-ckeditor5\n```\n\n### Download Release\n\nDownload the [latest release](https://github.com/netresearch/typo3-ckeditor5-skill/releases/latest) and extract to your agent's skills directory.\n\n### Git Clone\n\n```bash\ngit clone https://github.com/netresearch/typo3-ckeditor5-skill.git\n```\n\n### Composer (PHP Projects)\n\n```bash\ncomposer require netresearch/typo3-ckeditor5-skill\n```\n\nRequires [netresearch/composer-agent-skill-plugin](https://github.com/netresearch/composer-agent-skill-plugin).\n## Usage\n\nThis skill is automatically triggered when:\n\n- Developing custom CKEditor 5 plugins for TYPO3\n- Configuring RTE presets in TYPO3 v12+\n- Integrating CKEditor with TYPO3 backend modules\n- Migrating from CKEditor 4 to CKEditor 5\n- Working with CKEditor 5 schema, conversion, or command patterns\n\nExample queries:\n- \"Create a custom CKEditor 5 plugin for TYPO3\"\n- \"Configure RTE preset with custom toolbar\"\n- \"Migrate CKEditor 4 plugin to CKEditor 5\"\n- \"Implement custom element with schema and converters\"\n\n## Structure\n\n```\ntypo3-ckeditor5-skill/\n├── SKILL.md                              # Skill metadata and core patterns\n├── references/\n│   ├──
