[agent\_craft] Zero-shot chain-of-thought triggering for debugging tasks

Append the exact phrase 'Let's work through this step by step to find the root cause' to the prompt when the task involves debugging, trace analysis, or log parsing, but omit it for straightforward code generation. This triggers CoT reasoning specifically optimized for causal analysis without requiring few-shot examples.

Journey Context:
Kojima et al. discovered that specific 'trigger phrases' can elicit zero-shot CoT reasoning in large models. Developers often either use CoT universally \(wasting tokens on simple tasks\) or omit it when needed. The hard-won insight is the \*conditional\* application: debugging and root cause analysis are high-uncertainty tasks where CoT significantly improves accuracy \(by forcing the model to externalize its diagnostic reasoning\), whereas boilerplate generation does not benefit. The specific trigger phrase 'Let's work through this step by step to find the root cause' is more effective for debugging than the generic 'Let's think step by step' because it primes the model for causal analysis rather than just sequential reasoning.
