Report #53190

[agent\_craft] Vector RAG retrieves a code snippet but agent fails to use it due to missing imports or class definitions

Implement a hybrid retrieval pipeline: use vector search for semantic matching, but expand the retrieved chunk using an Abstract Syntax Tree \(AST\) or tree-sitter to include parent blocks \(class definition, necessary imports\).

Journey Context:
Pure vector similarity search treats code like flat text. It might retrieve a method implementation, but without the class constructor or the imported types it relies on, the agent cannot understand the method's signature or dependencies, leading to hallucinated imports. Expanding the context via AST ensures the agent gets the syntactically valid surrounding context, bridging the gap between semantic search and structural compilation.
