Some of the ideas here are codified in a simpler way in my TDD framework, CodeLeash (https://codeleash.dev).

The key difference is CodeLeash puts guardrails outside the model, as Claude Code hooks. It can’t forget or skip steps, it gets forced through a process. There are bypasses but they raise alarms that the model is also forced to review.

Putting guardrails outside the model forces deterministic process following. With a sufficiently capable process (TDD is a powerful way to build software) you can really scale up coding agent usage.
