Opty – A Zig-based HDC that reduces token use by up to 90%

I kept seeing people all over social media talking about how they were making custom local-LLM systems to help reduce the token load injected into their context window. On the side my recent project has me looking at Hyperdimensional Distributed Memory. I couldn't help but wonder if I could make an MCP server to improve token usage. Sure enough, using a combination of HDC + TOOL format, I was able to get opty's own self audit down by 93% in token usage. Still experimenting with large codebases but feel pretty good about how this should drive overall token usage down. Happy to hear any feedback.
