Report #57553

[agent\_craft] Agent generates broken code because RAG retrieved isolated functions without class structure or imports

Always retrieve at the AST node or class level, and include the file's import block and class signature alongside the target function. Better yet, retrieve the file path and line numbers, and let the agent use a read\_file\_lines tool to get the exact structural context it needs.

Journey Context:
Chunking code by raw token count or single functions destroys structural context. An agent seeing self.variable in a snippet doesn't know the class definition. Naive RAG returns the snippet matching the query, but coding requires structural integrity \(indentation, class scope, imports\). Retrieving just the path \+ signature \+ imports, then letting the agent request the full body, balances context window limits with structural awareness.
