10 Codebase Rules To Make Your AI Less Stupid

Your coding agent may not be stupid. Your repo may be teaching it to behave that way. The same model can look brilliant in one repo and useless in another because agents copy the environment they are given. Obvious commands, small files, clear ownership, searchable examples, and checks that reject bad code early all change how reliable AI coding feels in practice. The uncomfortable claim is that repo quality is now part of model quality. 0:00 Your repo is the agent's brain 1:04 10. One obvious command for every job 2:30 9. Small files with boring names 3:48 8. Examples that live next to the code 5:03 7. Tests that fail for the right reason 6:11 6. One source of truth for the rules 7:12 5. Typed boundaries that argue back 8:25 4. Generated code, clearly marked 9:26 3. Labels on the risky areas 10:22 2. Short tasks with a finish line 11:34 1.
