typo3-conformance
TYPO3 Extension Conformance Checker
Evaluate TYPO3 extensions against TYPO3 coding standards, architecture patterns, and best practices.
When to Use
- Extension quality / TER readiness
- Scored conformance reports
- Modernization to v12/v13/v14 (v14.3 LTS is default/gold standard)
Delegation
Testing -> typo3-testing | Docs -> typo3-docs | OpenSSF -> enterprise-readiness | Release/TER -> github-release
Raising the extension onto a newer TYPO3 version -> typo3-extension-upgrade, and stop here. Measured: asked to make an extension work with the current LTS, agents loaded this skill instead and delivered a conformance pass — ext_tables.php removed, deprecated calls searched, strict_types counted — then reported done. The manifest still named the old versions and nothing had been installed or tested against the new one. An audit of the current state is not an upgrade, and a widened constraint is not one either. If the request is a version raise, hand it over rather than auditing what is in front of you.
Scope: extensions only. Site/project repos (type: project + Compose) — score with the gold checker typo3-14-gold/tools/conformance.
