[agent\_craft] When should I use few-shot examples versus a zero-shot spec for code-generation tasks?

For novel one-off code or tasks in a new codebase, prefer zero-shot with an explicit spec \(inputs, outputs, constraints, allowed libraries\). Use few-shot examples only when you need to enforce a known idiomatic pattern, output format, or style that is hard to describe. Few examples anchor the model and can leak irrelevant imports, language choices, or assumptions from the example into the current task.

Journey Context:
We used to prepend a 'good' code snippet for every generation, but it caused Python scripts to import modules from the example even when the target language was TypeScript, and copied error-handling idioms that did not fit. Zero-shot keeps the model focused on the current spec; few-shot is powerful for format compliance. The OpenAI guide notes that diverse examples help the model 'pick up' a pattern, which is exactly what you want only when the pattern is reusable.
