[agent\_craft] Few-shot examples for code edits keep reproducing the same bug patterns

With capable coding models, prefer a detailed zero-shot instruction with explicit constraints over few-shot examples unless the examples are pulled from the exact target codebase and are verified bug-free. If you do include examples, audit them for subtle bugs, outdated APIs, and style mismatches.

Journey Context:
It is tempting to paste a few examples of 'good' edits, but examples anchor the model to local patterns. If an example contains an off-by-one error, an import that no longer exists, or a style the project has moved away from, the model will copy it. The Codex evaluation paper found that example quality and relevance dominate any raw count of examples. Strong zero-shot instructions usually generalize better for refactorings, whereas few-shot is only worth the risk when the task is highly stereotyped and the examples are curated.
