[counterintuitive] AI-generated code bugs are small and catchable like human bugs

When AI-generated code fails validation, regenerate with better constraints rather than attempting incremental patches; use type systems and comprehensive tests as hard binary gates, not soft suggestions

Journey Context:
Human code errors follow a gradient: off-by-one, wrong variable name, missing null check—small, local, and patchable. AI errors are fundamentally bimodal: when AI understands the intent, code is nearly perfect; when it misunderstands, it generates code that is structurally sound but semantically opposite to what is needed. A human might forget a null check; AI might implement the entire algorithm with the control flow inverted. The standard debugging workflow—find the bug, fix the bug—actively hurts when applied to AI code because patching catastrophically wrong code preserves the flawed mental model. You end up in an adversarial loop where each patch introduces new issues. The correct workflow: if AI code fails type checking or tests, regenerate with clarified constraints rather than debugging the broken output.
