Rust + SeaORM Database Explicit Contracts

This skill appears to do what it says: it gives guidance and a local CI-check script to enforce SeaORM entity conventions and doesn't request secrets or install external code. Before you install or let an agent run it: (1) inspect references/check_db_contracts.sh yourself to confirm the grep patterns and paths match your repo layout; (2) do NOT execute the schema-sync example (db.get_schema_registry(...).sync(...)) against production — that example would mutate the database schema if run with real DB credentials; (3) run the check script in an isolated CI or local environment so it only scans your repository (it reads files under the provided src_dir); (4) if you allow autonomous agents to invoke skills, ensure they are not given access to production DB credentials or environments where schema-sync could be executed. If you want extra assurance, run the script locally on a test checkout first and review any CI integration changes before committing.
