Report #84101

[agent\_craft] RAG retrieves syntactically similar but semantically irrelevant code snippets

Use hybrid retrieval: combine AST-based structure embedding \(function signatures, call graphs\) with lexical embedding, prioritizing recent git history and caller/callee relationships over simple vector similarity

Journey Context:
Vector similarity on raw code text retrieves files that use similar variable names or comments but different logic. Instead, index the Abstract Syntax Tree \(AST\) to capture this function calls X and this class inherits from Y. Weight recently modified files higher. Use call graph traversal to find relevant context, not just embedding similarity.
