A checklist for debugging AI-generated code

Disclosure: This article was created or edited with AI assistance. It is educational guidance, not a report of measured results. No measured productivity, hiring, sales or income outcome is claimed. Examples are illustrative unless a source is explicitly given.

Debugging AI systems is bigger than debugging code.

You are debugging assumptions, context, prompts, missing constraints, tool calls, silent hallucinations, and code that looks plausible long before it becomes trustworthy.

The output can be fast and polished and still be wrong in the exact place that matters.

A practical workflow:

  1. Isolate the failing behavior.
  2. Reproduce it with the smallest possible case.
  3. Inspect logs and diffs before asking for more code.
  4. Verify every confident claim the model makes.
  5. Shrink the context if the agent starts wandering.
  6. Add tests for the edge case that escaped.

If the model is still fighting you, stop prompting and read the source of truth.

Many AI mistakes survive only because humans keep negotiating with them instead of verifying them.

Record what you observed and what you verified. A polished explanation from a model is not evidence that the code works.
