It covers:\n\n- **Extension Scanner** - Backend module for diagnosing deprecated/removed APIs\n- **Rector** - Automated PHP code migrations\n- **Fractor** - Automated non-PHP file migrations (FlexForms, TypoScript, YAML, Fluid)\n- **PHPStan** - Static analysis\n- **PHPUnit** - Testing framework setup\n\n## Scope\n\nThis skill is for **extension developers** upgrading extension code. It does NOT cover:\n- Upgrading TYPO3 project installations\n- TYPO3 core upgrades\n- Site/instance migrations\n\n## Supported Upgrade Paths\n\n| From | To | Status |\n|------|-----|--------|\n| v7 | v8 | Documented |\n| v8 | v9 | Documented |\n| v9 | v10 | Documented |\n| v10 | v11 | Documented |\n| v11 | v12 | Documented |\n| v12 | v13 | Documented |\n| v13 | v14 | Monitoring |\n| v12 | v12+v13 (dual) | Documented |\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-extension-upgrade-skill --skill typo3-extension-upgrade\n```\n\n### Download Release\n\nDownload the [latest release](https://github.com/netresearch/typo3-extension-upgrade-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-extension-upgrade-skill.git\n```\n\n### Composer (PHP Projects)\n\n```bash\ncomposer require netresearch/typo3-extension-upgrade-skill\n```\n\nRequires [netresearch/composer-agent-skill-plugin](https://github.com/netresearch/composer-agent-skill-plugin).\n## Usage\n\nThe skill activates automatically when Claude detects:\n- TYPO3 extension upgrade requests\n- Compatibility issues with newer TYPO3 versions\n- Extension modernization tasks\n\nExample prompts:\n- \"Upgrade this extension to TYPO3 v13\"\n- \"Make this extension compatible with TYPO3 12 and 13\"\n- \"Fix the deprecated API usage in this TYPO3 extension\"\n\n## Contents\n\n```\ntypo3-extension-upgrade-skill/\n├── SKILL.md                 # Main skill instructions\n├── README.md                # This file\n├── assets/                  # Configuration templates\n│   ├── rector.php           # Rector configuration\n│   ├── fractor.php          # Fractor configuration\n│   ├── phpstan.neon         # PHPStan configuration\n│   ├── phpunit.xml          # PHPUnit configuration\n│   └── .php-cs-fixer.php    # PHP-CS-Fixer configuration\n└── references/              # Detailed documentation\n    ├── api-changes.md       # Version-specific API migrations (v7-v14)\n    └── pre-upgrade.md       # Pre-upgrade checklist\n```\n\n## Key Resources\n\n### Official TYPO3 Changelogs\n\n- [v14 Changelog](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog-14.html)\n- [v13 Changelog](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog-13.html)\n- [v12 Changelog](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog-12.html)\n- [v11 Changelog](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog-11.html)\n\n### Tools\n\n- [TYPO3 Rector](https://github.com/sabbelasichon/typo3-rector) - PHP migrations\n- [TYPO3 Fractor](https://github.com/andreaswolf/fractor) - Non-PHP migrations\n- [Extension Scanner](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/HowTo/UpdateExtensions/ExtensionScanner.html) - API diagnostics\n\n## Author\n\n**Netresearch DTT GmbH**\n[https://www.netresearch.de/](https://www.netresearch.de/)\n\nNetresearch is a Leipzig-based technology company specializing in e-commerce, logistics, and TYPO3 solutions.
