typo3-extension-upgrade skillA

typo3-extension-upgrade is agent-read markdown (skill) from netresearch/typo3-extension-upgrade-skill: Use when an extension has to work with a newer or the current TYPO3 LTS, when a version bump breaks compatibility or leaves deprecated APIs behind, when upgrading v11->v12, v12->v13 or v13->v14 (v14.3 LTS is the current target), when one codebase must stay compatible with two versions, when running Extension Scanner, Rector, Fractor or PHPStan against a target version, or when a specific v14 breaker bites - Fluid 5 strict ViewHelpers, HashService removal, the ext_tables.php split..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add netresearch/typo3-extension-upgrade-skill/typo3-extension-upgrade@git:20260905.acec6f9
Exact content
mdr add netresearch/typo3-extension-upgrade-skill/typo3-extension-upgrade@sha256:4078b00b7869ceca

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
