Report #6028

[agent\_craft] RAG pipeline returns code snippets that lack structural context, causing agent to write broken code

Never chunk code for RAG at a fixed token limit. Use AST-aware chunking \(functions/classes\) and always retrieve the file path and signature context. For coding agents, prefer a two-stage retrieval: find relevant chunks, then load the entire parent file if it fits within the context budget.

Journey Context:
Standard RAG splits text into arbitrary 512-token chunks. Code is highly structured; a chunk missing the class definition, imports, or global variables is useless. Agents then hallucinate missing variables or misinterpret scope. AST-aware chunking preserves logical boundaries. The two-stage approach \(chunk to find, file to read\) balances retrieval efficiency with the structural integrity required for accurate code generation.
