# LeanCTX — Context Gateway for AI agents

Control what your AI can see. LeanCTX provides local context selection,
supported access and content controls, and evidence of observed context operations
for existing agents: Select → Control → Learn → Prove. Learn means local task and
knowledge continuity, not model training. Recovery depends on source or
archive availability and access permissions. LeanCTX | SDK is the separate
integration surface for applications.

lean-ctx shapes context before it reaches you: cached reads, compressed shell
output, focused search, recovery to exact source. Two rules beat every detail:

1. **Fewer round trips beat smaller outputs.** One call that answers the
   question is cheaper than three small ones. Never add a call just to save a
