[agent\_craft] Few-shot examples anchor model on deprecated patterns from the examples

Use 'semantic few-shot': replace concrete identifiers in examples with abstract placeholders \(FUNC\_1, VAR\_A\) to force pattern matching without surface form anchoring

Journey Context:
Providing 2-3 examples of desired output helps format adherence, but for code, the model copies variable naming conventions, specific library versions \(e.g., pandas 1.x vs 2.x syntax\), or deprecated APIs present in the examples. This is 'surface form competition' - the examples interfere with the actual codebase patterns. Zero-shot avoids this but lacks structural guidance. The middle path is 'semantic few-shot': abstract the examples to AST-level patterns \(signatures only\) or replace all concrete identifiers with numbered placeholders \(VAR\_1, FUNC\_A\). This forces the model to map patterns to the actual codebase's conventions rather than copying surface syntax.
