Report #95791

[agent\_craft] Agent fails on novel API patterns \(e.g., cursor pagination\) despite strong base model because pattern is rare in training

For API patterns not common in pre-training \(GraphQL, cursor pagination, specific OAuth flows\), always include 1-2 few-shot examples of the request/response cycle in the system prompt, even for strong models like GPT-4/Claude.

Journey Context:
Zero-shot works for common patterns \(REST GET/POST\) because they appear frequently in training data. However, niche patterns like cursor-based pagination \(\`?after=xyz\`\), specific header signatures, or GraphQL variable structures are 'out-of-distribution' for in-context learning. Research shows few-shot examples are essential for 'extreme classification' or novel formats. The cost of 2 examples is negligible compared to the cost of a failed API call. This is particularly critical for code agents interacting with niche internal APIs where zero-shot assumptions fail.
