Documentation dies the day it's written. So I built a second brain for code that keeps itself up to date.
It reads your GitHub repos and writes a wiki where every claim links to the exact lines, at the exact commit. 🧵

@0xAffan Agreed: today it rejects invented citations, but doesn't yet check that each claim matches its cited lines. That's the next eval!

How RAG search works, step by step, in llm-repo-wiki:
1. Full-text search finds the words
2. Vector search finds the meaning
3. Reciprocal rank fusion merges both lists
4. One answer from the top chunks, and any citation not grounded in them is stripped
