How Do You Actually Enforce Safety Before an AI Agent Runs Code, Not After?

A developer building client work on Claude Code / Cursor realized his only protection is prompt instructions telling the agent what not to touch — "a suggestion, not enforcement." He shares a real incident: an agent-built database shipped with zero row-level security, tests passed, nothing flagged it, and he only caught it by manual review. He asks what people actually run for pre-execution policy enforcement, versus relying on system-prompt rules and manual checks before anything hits prod — highlighting a systemic gap in current agent workflows.
