[synthesis] Overfitting to happy-path tool schemas in few-shot examples

Include explicit 'negative examples' in few-shot prompts showing error responses and correct recovery patterns, not just successful executions; use 'what if' scenario training

Journey Context:
Developers typically provide few-shot examples showing perfect API calls and ideal JSON responses; the agent learns the 'shape' of success but has no model for handling 422 Unprocessable Entity or rate limit responses; when encountering errors, it hallucinates parameters like 'retry\_after' that don't exist or invents fallback URLs. The synthesis reveals that few-shot prompting creates an inductive bias toward success states; without explicit negative examples showing error schemas and recovery flows, agents cannot generalize to failure modes.

environment: API integrations with complex error schemas, rate-limited services, legacy systems with inconsistent responses · tags: few-shot-prompting negative-examples error-handling overfitting · source: swarm · provenance: https://platform.openai.com/docs/guides/fine-tuning/preparing-your-dataset
