Could you build this?
Partial Creating a CLI tool wrapper is simple, but designing, fine-tuning, and running local multi-vector code retrieval models (such as ColBERT for code) with fast local indexing requires non-trivial ML search expertise.
What it would actually take: The system combines ripgrep-style regex matching with a multi-vector Late Interaction retrieval model (like ColBERT) quantized for fast local CPU/GPU inference (ONNX or candle/ggml). The difficult part is building low-latency multi-vector indexing and scoring (token-level MaxSim) combined with inverted indices over code abstract syntax trees (ASTs), demanding specialized knowledge in information retrieval and model optimization.
