Report #90221

[agent\_craft] Agent uses deprecated patterns for standard libraries or invents non-existent APIs for new frameworks

Use zero-shot for well-documented standard libraries \(Python stdlib, React hooks\) to avoid biasing toward older patterns; use few-shot with 2-3 current examples for emerging or rapidly evolving APIs \(e.g., new OpenAI beta features, experimental React compiler\).

Journey Context:
Few-shot examples for standard libraries often contain deprecated patterns from older codebases \(e.g., using urllib instead of requests, or class components instead of hooks\). This creates 'regression to the past.' Conversely, zero-shot for brand new APIs leads to hallucination because the model hasn't seen enough examples in training. The fix: dynamically select prompting strategy based on API release date and documentation freshness. For stable APIs \(2019\+\), zero-shot prevents outdated idiom injection. For alpha/beta APIs, curated few-shot examples anchor the model to actual syntax.
