Doctrine — entities, migrations, repositories

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 persist data in a relational DB — create/read/update/delete entities, write queries, manage schema with migrations.

For console commands that walk a large or growing dataset (imports, backfills, re-syncs — any "loop over every row" job), read references/imports.md before writing code: it covers ID-first loops, per-iteration clear(), DBAL side effects, and sync-dispatched side effects.
