[agent\_craft] Static few-shot examples in system prompt hurt performance on diverse coding tasks

Replace static few-shot examples with dynamic retrieval: embed the user's current task \(code snippet \+ intent\), retrieve the top-K most similar successful examples from a vector store of past solutions, and inject those as context-specific few-shot examples for the current turn only.

Journey Context:
Hard-coding 3-5 examples in the system prompt works for narrow domains but fails for general coding agents because the examples rarely match the current language, framework, or pattern. This mismatch actively confuses the model \(negative transfer\). The solution is 'in-context example retrieval': maintain a bank of solved tasks with embeddings. When a new request arrives, perform a similarity search to pull relevant examples \(e.g., 'how to refactor React hooks' when the user asks about Vue composition API might be less relevant than a general 'refactor to composition pattern' example\). This provides positive transfer, reduces token waste on irrelevant examples, and allows the example bank to scale infinitely without hitting context limits.
