Report #87002

[agent\_craft] RAG pipeline retrieves irrelevant code boilerplate and test files instead of core logic

Filter retrieved chunks by file type \(exclude test, mock, config files unless specifically asked\) and use structural code retrieval \(AST-based chunking\) instead of naive sliding-window chunking.

Journey Context:
Naive RAG splits code by character count, breaking function definitions and class structures. It also indexes everything equally, so a highly commented test file might rank higher than a dense core module. AST chunking respects code boundaries, and metadata filtering ensures the agent only sees implementation files, drastically improving retrieval precision.
