[counterintuitive] AI coding agents can reliably self-correct their code by reviewing their own output

Always provide external validation feedback — test results, compiler errors, linter output, execution traces — when asking AI to correct its code. Never rely on the AI to find its own mistakes by thinking harder or re-reading its output without new information. Build pipelines where AI writes code, executes it, receives real error signals, and then corrects.

Journey Context:
A widespread practice is asking AI to review your answer or find any mistakes, assuming the model can catch its own errors through self-reflection. Huang et al. \(2023\) showed that without external feedback, LLM self-correction does not reliably improve reasoning or code quality. The model tends to either repeat its original error or introduce new ones while correcting. The intuition: if the model lacked the knowledge or reasoning to produce the correct answer initially, re-reading its own output does not add new information. However, self-correction DOES work when the model receives external grounding — test failures, type errors, execution traces — because this provides genuinely new information the model can reason about. This is counterintuitive because humans can often find their own mistakes by re-reading their work, and we project this ability onto AI. The key difference: humans have a separate verification faculty; LLMs are doing the same forward pass that produced the error.
