[agent\_craft] Chain-of-Thought wastes tokens on simple queries but is needed for complex logic

Do not put 'think step by step' in the system prompt universally; instead, append 'Let's work through this step by step to avoid mistakes' only to user queries that involve multi-step logic, math, or complex debugging

Journey Context:
Universal Chain-of-Thought \(CoT\) in the system prompt causes the agent to overthink simple tasks \('Let me think step by step: 1. The user said hello...'\), burning tokens and increasing latency. However, zero-shot CoT is crucial for complex debugging or math. The hard-won insight is conditional triggering: the system prompt should tell the agent 'Only use step-by-step reasoning for complex problems,' and the user-side prompt should explicitly trigger it for those cases. This balances token efficiency with accuracy.
