Report #1335

[agent\_craft] RAG pipeline retrieves code chunks that lack class definitions and imports, causing hallucinated variables

Implement a two-pass retrieval: 1\) Semantic search for the target logic, 2\) AST-based structural expansion to pull in the parent class definition, imports, and sibling methods.

Journey Context:
Pure vector similarity search returns syntactic islands. An agent trying to edit a method needs the class variables and imports to avoid hallucinating undefined variables or incorrect signatures. Expanding the retrieval window via AST parsing ensures the agent gets the necessary scaffolding, trading a slight increase in context tokens for a massive reduction in compilation errors.
