Report #42290

[agent\_craft] Agent includes specific few-shot examples that constrain the model to obsolete API patterns or hallucinated syntax

Use 'analogical' few-shot examples from different technical domains rather than identical task examples; or use zero-shot with strong type signatures and documentation context.

Journey Context:
Standard prompt engineering recommends few-shot examples, but in coding agents, this is dangerous: if your example uses React Class components, the model will generate Class components even for modern functional React code. The model overfits to the specific syntax in the example. The hard-won insight from production code agents: do not show examples of the exact task. Instead, show examples of the reasoning pattern from a different domain \(e.g., show a Python refactoring example when asking the agent to refactor JavaScript\). This teaches the 'shape' of the solution without prescribing specific API calls. Alternatively, use zero-shot with exhaustive type definitions and docstrings, which avoids version lock-in entirely.
