Show HN: Smart Router Kit – Prevent "Garbage in" for RAG Using Pydantic and LLMs

[2dogsanerd]

Yesterday I shared my Ingest Kit here. Today I'm releasing the second part: The routing logic.

Problem: Blindly chunking every PDF leads to bad retrieval. Solution: A small LLM pass (Traffic Controller) that routes documents to semantic collections (Finance vs Tech) and selects chunking strategies (Table-Aware vs Standard) before ingestion.

It's a simple pattern using Pydantic to force structured decisions from local LLMs (Ollama).
