Start at https://github.com/cadamsdotcom/CodeLeash/blob/main/.pre-com... where you’ll see the custom lints.

Then have a look at https://github.com/cadamsdotcom/CodeLeash/blob/main/scripts/... (which was test-driven alongside https://github.com/cadamsdotcom/CodeLeash/blob/main/tests/un...)

The script can exit 2 to block the agent, and whatever it prints to stderr is shown to the agent. That’s a pretty darn flexible way to enforce whatever you like.

Despite this being in the codebase I still have no idea what python’s ast stuff is or does - I just let the agent rip, ensured it did TDD and reviewed it all to make sure the tests & code looked reasonable. I didn’t write this code and don’t want to. But I’ve watched it catch hundreds of dumb AI-isms, and watched the agent go “okay” and fix them ;) it’s been paying for itself over and over for months :)
