Report #66526

[synthesis] Agent exceeds token limits or incurs high costs on simple tasks due to aggressive Chain of Thought reasoning

Use reasoning models only for complex logic/planning, not for standard tool execution. For Claude, use standard CoT prompts for complex tasks, but omit them for simple tasks as it does not require explicit CoT to follow instructions.

Journey Context:
Agents often default to the smartest model for everything. OpenAI's reasoning models are stateful and expensive for trivial tasks. Claude's standard model is highly instruction-following without needing explicit CoT scaffolding. Routing based on task complexity is essential for cost control.
