Report #24306

[frontier] Naive vector search RAG returning irrelevant code snippets for complex debugging or multi-file refactoring

Replace embedding-similarity RAG with Agent-mediated Graph RAG. Route queries to an agent that traverses Abstract Syntax Trees \(AST\) and dependency graphs using tools like 'find\_references' or 'get\_call\_graph' rather than relying on semantic similarity search.

Journey Context:
Top-k embedding search misses structural dependencies. A function might call another file, but their embeddings aren't semantically similar. Production coding agents are moving to graph-based traversal where the LLM uses code-navigation tools to walk the codebase, mimicking how a human developer uses an IDE. This ensures the agent gets the exact execution flow, not just textually similar chunks.
