If you’re interested in such deterministic scaffolding/control flow, check out Probity.

I created it to address this exact issue. It is a vendor-neutral ESLint-style policy engine and currently supports Claude Code, Codex, and Copilot.

It uses the agents hooks payloads and session history to enforce the policies. Allowing it to be setup to block commits if a file has been modified since the checks were last run, disallow content or commands using string or regex matching, and enforce TDD without the need of any extra reporter setup and it works with any language.
