GPT-5 (Codex) follows instructions exactly as given. Usually a good thing, but sometimes, it this is what happens.
AGENTS.md: ALWAYS WRITE TESTS before coding.
Codex: Let me begin with the tests. (Spends 5 minutes writing tests.)
Anand: Stop! This is a proof of concept. We don’t need tests!
AGENTS.md: Write tests before coding. Drop tests for proof-of-concepts.
Codex: (Proceeds to delete all existing tests.)
Anand: STOP! We need those tests!
AGENTS.md: For new code, or if tests exist, start by writing tests.
Anand: Do this task. … BUT SKIP TESTS! This is a POC!
Codex: The user has explicitly asked to skip tests. But the guidelines require tests for new code. For now, I think I will skip tests.
Anand: (sigh!)
Reminds me of Chaplin’s Feeding Machine.
