[counterintuitive] Forcing Chain-of-Thought on every coding step improves reliability

Apply Chain-of-Thought selectively for planning and complex logic, but use direct generation for simple, well-defined syntax translation or boilerplate.

Journey Context:
The belief that CoT always helps leads agents to output 'Let's think step by step' before writing a simple CSS rule or a standard CRUD endpoint. For highly deterministic, syntactical tasks, forcing CoT can actually increase hallucination rates or lead to over-engineering, because the model starts rationalizing non-existent complexities. CoT is a reasoning crutch; use it when the path is ambiguous \(architecture, debugging\), not when the destination is a known, simple pattern.
