You don't just code with AI, you provide 2 things

1. a detailed spec, result of your discussions with the agent about work, when it gets it you ask the agent to formalize it into docs

2. an extensive suite of tests to cover every angle; the tests are generated, but your have to ensure their quality, coverage and depth

I think, to make a metaphor, that specs are like the skeleton of the agent, tests are like the skin, while the agent itself is the muscle and cerebellum, and you are the PFC. Skeleton provides structure and decides how the joints fit, tests provide pain and feedback. The muscle is made more efficient between the two.

In short the new coding loop looks like: "spec -> code -> test, rinse and repeat"
