[agent\_craft] Static few-shot examples become stale or introduce stylistic noise from unrelated files

Implement semantic few-shot retrieval: embed the current task description, query a vector store of \(task\_embedding -> solution\) pairs using cosine similarity >0.7, and inject only the top-2 matches as few-shot examples. If no matches exceed the threshold, fall back to zero-shot with an explicit style guide \(e.g., 'Use Google-style docstrings'\). Never use random files as few-shot examples.

Journey Context:
Few-shot examples anchor the model to specific syntax, but if the examples are from a different domain \(e.g., showing a React component when the task is a SQL query\), they act as distractors and increase token count without benefit. Hard-coding examples in the system prompt leads to staleness as the codebase evolves \(e.g., still showing Python 2 patterns after a migration\). We observed that agents given 5 random files from a repo as few-shot context produced Frankenstein code mixing styles. The correct approach is to treat few-shot examples as retrieved context: index previous successful agent tasks with embeddings, and at query time, retrieve semantically similar solved tasks. This ensures the style is current and contextually relevant. This aligns with 'What Makes Good In-Context Examples' \(semantic similarity matters most\) and Anthropic's guidance on exemplar relevance.
