[agent\_craft] Chain-of-thought reasoning degrades code generation accuracy when appended to user queries

Embed reasoning instructions in the system prompt \(e.g., 'First, analyze the error trace step-by-step in tags'\) or provide few-shot examples showing reasoning chains, rather than asking the user to 'think step by step' in the query

Journey Context:
Appending 'think step by step' to user content competes with the actual task tokens for attention, and models may skip it to answer faster. Embedding it in the system prompt establishes a behavioral prior. Few-shot examples are even stronger because they demonstrate the exact reasoning format expected. Research shows CoT in system prompts reduces reasoning errors by 15-20% compared to user-query append for coding tasks.
