Report #48937

[agent\_craft] RAG pipeline retrieves irrelevant code snippets that lack structural awareness

Index and retrieve code using Abstract Syntax Trees \(AST\) or chunk by semantic blocks \(functions/classes\) rather than fixed character counts, and include the file path and parent class/function signature in the retrieved context.

Journey Context:
Fixed-size chunking splits functions in half, destroying local coherence. When an agent retrieves a snippet, it often lacks the imports or class definition needed to understand it. AST-based chunking preserves semantic boundaries. Adding structural metadata gives the agent the frame needed to situate the code without loading the whole repo.
