Report #5908

[agent\_craft] RAG pipeline retrieves too many code snippets, diluting context with incomplete functions

Retrieve a low top-k \(3-5\) chunks, but programmatically expand each chunk to include its AST parent or enclosing block to ensure complete function or class definitions.

Journey Context:
Code snippets without boundaries break syntax understanding, and the agent cannot call a function if its signature is cut off. Over-fetching to get full functions wastes tokens. AST-aware retrieval gives complete scopes without over-fetching, maximizing signal-to-noise ratio for the coding agent.
