How to build your own fun and absurd pair programmer
summary
A kooky pair programmer called Pip is a Spring Boot + Kotlin backend with a tiny Python service, a local vector DB of ~25k Slack messages, and a 9B local model (qun 3.5) that runs entirely locally. It uses RAG: sparse+dense prefetch then multi-vector rerank to pull 3 best contexts in milliseconds, streams answers, can play Pong or tic‑tac‑toe, call MCP tools (Spotify, memes), and deliberately rejects rude CI requests — but MCP tool calling raises real security and guardrail complexity.
