## The problem

Every file Claude reads stays in the context window until the session ends. On a 20-file codebase, by the time Claude reaches synthesis it's carrying 40,000+ tokens of raw source — most of which it already processed, will never need again verbatim, and is paying for on every single API call.

**Caveman** compresses what Claude *says*. **SMOS** compresses what Claude *holds* — the files, the prior analysis, the context window itself.

## How it works

SMOS is an MCP server that gives Claude a persistent memory layer: FAISS vector search + SQLite, powered by a local LLM (qwen2…
