[counterintuitive] Does forcing Chain-of-Thought \(CoT\) reasoning always improve an agent's accuracy on coding tasks?

Apply CoT selectively. Use it for algorithmic or mathematical logic, but disable it for simple retrieval, formatting, or highly constrained tasks where it introduces unnecessary latency and increases the surface area for hallucination.

Journey Context:
CoT is a token-inefficient tradeoff. It trades compute/time for accuracy on complex reasoning. On simple tasks, forcing the model to 'think step-by-step' often leads it to overthink, hallucinate constraints, or contradict itself before arriving at an obvious answer. For code generation, if the path is deterministic, zero-shot direct generation is often more reliable and strictly faster.
