Show HN: Muninn – A universal local-first memory layer for AI agents

Hi HN, I built Muninn because I was tired of dumping entire directories into LLM contexts just to keep my agent updated.

Most memory layers use complex vector DBs. Muninn uses a simple, transparent approach: it indexes your project into local Markdown files and surgically injects only the top-relevant facts using the CXP (Context Exchange Protocol) powered by Rust.

Local-first: Everything stays in ~/.muninn. Universal: Works across different agents (Claude, Cursor, etc.). Token-efficient: Reduces context overhead by up to 95%. Would love to hear your thoughts on the local-first context approach!
