[agent\_craft] Static few-shot examples in system prompt waste tokens on irrelevant patterns or degrade performance on out-of-distribution tasks

Implement semantic few-shot retrieval: embed the current task \(code diff, error message, or user query\), fetch top-k historically successful trajectories or similar solved problems from a vector store, and inject them as dynamic few-shot examples rather than hardcoded ones.

Journey Context:
The 'What Makes Good In-Context Examples' paper demonstrated that example selection based on semantic similarity \(using embeddings\) to the query significantly outperforms random or fixed selection, often by 10-20% on code tasks. Static few-shots in system prompts assume a stationary task distribution, which fails for general-purpose coding agents that encounter diverse languages, frameworks, and project-specific conventions. By treating historical trajectories \(previous successful tool sequences\) as a dynamic few-shot pool \(retrieval-augmented generation for prompts\), the agent adapts to the current codebase's patterns and the specific error messages being encountered. This requires maintaining a memory bank of \(task\_embedding, solution\_trace\) pairs and retrieving them at inference time, effectively implementing case-based reasoning that improves with experience rather than remaining static.
