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

Allow the model to output reasoning in a structured, parseable block \(e.g., ...\) that the agent can strip, or use a reasoning model that handles this natively.

Journey Context:
Developers often tried to suppress CoT to keep output clean. However, suppressing reasoning degrades accuracy significantly because autoregressive generation is the model's computation. You cannot compute in hidden layers what must be generated autoregressively. Modern agent frameworks use structured tags to separate reasoning from final output, preserving accuracy while keeping the UI clean.
