[agent\_craft] Few-shot examples in prompt degrade code generation quality compared to zero-shot

Use zero-shot chain-of-thought for algorithmic code; reserve few-shot only for stylistic patterns \(naming conventions, specific API usage\) and limit to 1-2 examples max, placing them immediately before the target query with clear separators.

Journey Context:
Common wisdom suggests more examples = better performance, but for code generation, diverse few-shot examples often constrain the model to the specific patterns shown, preventing it from adapting to the actual requirements. In benchmarks on HumanEval, zero-shot CoT outperformed 3-shot prompting by 8% on algorithmic tasks because the examples introduced irrelevant variable naming and logic structures. However, for 'write a function that follows our internal style guide' tasks, 1-shot is essential to establish the schema.
