[counterintuitive] AI can effectively review and fix its own generated code through self-correction

Provide external feedback signals \(compiler errors, test results, lint output\) when asking AI to correct its code; never ask AI to self-correct without grounding in external evidence; use a different model or prompting strategy for review than for generation when possible

Journey Context:
Self-correction in LLMs is surprisingly ineffective without external feedback. When asked to review your code for bugs, the model tends to confirm its own reasoning rather than finding genuine errors. This is because the models review is conditioned on the same knowledge and biases that produced the code. Studies show that LLM self-correction without external grounding often makes code worse not better by introducing new bugs while fixing imagined ones. However self-correction WITH external signals is highly effective: the model can fix problems when given concrete evidence like compiler errors, test failures, or lint output. The key distinction: self-correction without external grounding is mostly theater; self-correction with external feedback is genuinely powerful. For AI coding agents, this means always run code, run tests, and feed results back before attempting fixes.
