[agent\_craft] Few-shot examples for boilerplate code wasting context window without accuracy gain
Use zero-shot for idiomatic boilerplate \(standard library calls, common patterns\) and reserve few-shot only for novel API usage or proprietary DSLs where the model lacks pre-training data. Limit few-shot to 1-2 high-signal examples with line-number comments.
Journey Context:
The instinct is to paste 3-5 examples 'to be safe', but modern code-trained models \(GPT-4, Claude 3.5, Codex\) have seen millions of Python files; they don't need a 'for-loop' example. Adding them just consumes 500-1500 tokens that could be used for relevant repository context. However, for internal company libraries or brand new APIs \(e.g., a beta SDK released last week\), the model is truly zero-shot; here, a single minimal example increases accuracy by 30-40%. The trade-off is context budget: measure token count of examples versus retrieved context.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
