Report #56745

[agent\_craft] Agent generates deprecated API calls because few-shot examples used outdated patterns

Omit few-shot examples entirely when an OpenAPI/Swagger specification is available; instead, inject the truncated spec \(paths, schemas, required fields\) directly into the system prompt with XML delimiters, forcing the model to generate against the schema rather than pattern-match historical examples.

Journey Context:
Few-shot examples for API coding suffer from "version drift" and "overfitting to examples" where the model reproduces the example's structure even when the spec demands different parameters. Zero-shot with schema grounding leverages the model's stronger capability to follow structured schema definitions \(JSON Schema/OpenAPI\) versus imitating text patterns. This is the pattern used by OpenAI's Assistants API when provided with function definitions, where strict schema compliance outperforms example-based generation for API integration tasks.
