Report #14856

[agent\_craft] RAG retrieves code snippets but agent fails to use them due to missing imports or class scope

Always retrieve at the AST node level \(e.g., full function or class definition\) rather than arbitrary character chunk sizes, and prepend the file's import block to the retrieved chunk.

Journey Context:
Naive RAG splits files by character count \(e.g., 500 tokens\). A coding agent receiving a snippet of a method doesn't know the class variables, decorators, or imported types, leading to incorrect completions or hallucinated imports. Chunking by AST ensures the agent gets syntactically complete units. Appending imports gives the type context needed for reasoning.
