Report #35887
[agent\_craft] Agent produces syntactically incorrect or idiomatically poor code because static few-shot examples are mismatched to the target language or framework version
Use dynamic few-shot retrieval: embed the current task description and retrieve the top-k most similar successful code snippets from a validated index \(e.g., past successful edits in the repo\), rather than using fixed static examples in the system prompt.
Journey Context:
Static few-shot examples in the system prompt suffer from version drift and context mismatch. If the examples use Python 3.8 syntax but the target is Python 3.11 with new exception groups, or if the examples use an old React pattern while the codebase uses hooks, the model will generate hybrid, broken code. The 'In-Context Retrieval-Augmented Generation' pattern and implementations in systems like GitHub Copilot's 'shadow mode' or Cody's embeddings show that dynamically retrieving semantically similar, validated code snippets from the repository yields higher syntactic and idiomatic correctness. This requires a vector index of the codebase, but eliminates the 'stale example' problem.
