Context Window Manager

Context Window Manager Handbook

Context Window Manager (CWM) solves the context exhaustion problem in LLM applications. Instead of losing your conversation history when context fills up, CWM lets you freeze, thaw, clone, and resume your sessions with zero information loss.

How it’s different

Section titled “How it’s different”

Unlike summarization or RAG approaches, CWM preserves actual KV cache tensors. Thaw a frozen window and the model resumes from the exact same cognitive state — no approximation.

Stack

Section titled “Stack”

CWM leverages:

  • vLLM’s prefix caching with cache_salt for session isolation
  • LMCache for tiered KV cache storage (GPU → CPU → Disk → Redis)
  • MCP protocol for seamless integration with Claude Code and other clients
