[counterintuitive] Instructing the model 'do not output your reasoning' or 'think silently' to save output tokens

Allow the model to output its reasoning, or use models with native hidden reasoning tokens; do not suppress CoT with prompt instructions.

Journey Context:
Chain-of-thought is a computational process, not just a reporting mechanism. If you tell an LLM not to output its thoughts, it often skips the reasoning step entirely, leading to significantly worse logic and more bugs in the final code. The tokens spent on reasoning are the cost of accuracy. If token cost is a concern, use API features that discount reasoning tokens \(like o1-mini\) or smaller models, rather than crippling a larger model's reasoning capability with a prompt hack.
