symfony/validator

If the project contains .ddev/config.yaml, prefix every shell command with ddev (full mapping in the symfony skill's references/ddev.md). Examples target Symfony 7.4, 8.0 and newer — verify the installed version before using newer features.

When to use

You need to validate data — form input, API payloads, domain invariants.

Replaces
