Report #51460

[agent\_craft] Static few-shot examples in system prompt become irrelevant as the agent encounters novel error types, causing performance degradation on rare edge cases \(e.g., specific HTTP status codes, database deadlock errors\)

Implement a dynamic few-shot selector that retrieves examples from a vector database indexed by error message signature \(truncated hash of error type \+ file extension\), injecting 2 relevant examples only when the current error matches a historical pattern with >0.85 cosine similarity.

Journey Context:
Static few-shot examples assume a stationary distribution of tasks, but coding agents face heavy-tailed error distributions \(e.g., specific SSL certificate errors, race conditions\). Randomly injecting examples wastes context window on irrelevant patterns. The correct approach is embedding-based retrieval: encode historical \(error\_message, solution\) pairs, and at inference time, embed the current error, retrieve top-k neighbors, and prepend them as few-shot examples. This maintains context efficiency \(only 2 examples vs 5 static ones\) while increasing relevance. This pattern is derived from DSPy and Berkeley's research on example retrieval for compound AI systems.
