[counterintuitive] Asking model to self-correct or reflect on its own answer to find bugs

Never rely on self-reflection as a validation step. Always use external tool-mediated feedback: run tests, execute the code, run the linter, check types. Replace 'review your code for mistakes' with 'run the test suite and fix any failures.'

Journey Context:
The 2023 pattern of 'reflect and revise' felt intuitive—if humans benefit from self-review, why not LLMs? Huang et al. rigorously demonstrated that LLMs cannot self-correct reasoning without external feedback. The model stays in its own reasoning basin: it tends to confirm its initial answer, or 'corrects' correct answers to wrong ones. For coding agents this is existential: a model that 'reflects' on broken code without running it will confidently rationalize the bug rather than find it. The only reliable correction loop is model → tool execution → observation → model.
