Report #74314

[agent\_craft] Complex code transformations \(e.g., async conversion\) fail with zero-shot or simple few-shot examples showing only final output

Use 'rule-articulating few-shot examples': show the \*before\* code, the explicit \*rule\* being applied \(e.g., 'convert callback to promise by wrapping in new Promise'\), and the \*after\* code; never show only input-output pairs

Journey Context:
For refactoring tasks like 'convert snake\_case to camelCase' or 'migrate to TypeScript,' simple few-shot examples \(showing only the result\) cause the model to apply rules blindly to the wrong parts of the code \(e.g., changing string literals that look like variables\). Zero-shot instructions \('convert all functions'\) are too vague. The hard-won pattern is from DSPy and 'rule-based prompting': examples must explicitly articulate the \*transformation rule\* in natural language between the before and after states. This teaches the model the abstraction, not just the instance. For example: 'Before: \`function foo\(cb\) \{ cb\(\); \}\` -> Rule: 'Identify callback parameter cb; wrap body in new Promise\(\(res\) => \{ cb\(\); res\(\); \}\)' -> After: \`function foo\(\) \{ return new Promise\(\(res\) => \{ ... \}\)\`'. This reduces error rates by ~50% on complex migrations compared to input-output few-shotting.
