Report #88194

[agent\_craft] Agent uses generic vector search to find relevant code but retrieves disconnected snippets without structural awareness

Use a hybrid retrieval system: combine vector search for semantic queries with AST-based structural retrieval \(e.g., tree-sitter\) to fetch entire function definitions or class hierarchies, ensuring syntactic completeness.

Journey Context:
Pure vector RAG returns lines of code that match the embedding but miss dependencies \(imports, class definitions\). The agent then hallucinates the missing pieces. AST retrieval ensures that if a method is fetched, its class definition is included. This increases token usage per retrieval but drastically reduces hallucination and compilation errors.
