LeoSIS gives an application one API surface and lets the provider behind it change without the application changing with it.
Status
In development. There is nothing to install yet, and this page will say so until that changes. PeepSick Labs builds in public, which includes being plain about what does not exist.
USB is the studio's product that is live today. If you want to follow LeoSIS as it lands, watch github.com/PeepSick or get in touch.
Where it fits
The three pieces are meant to stack: USB installs skills, Foundry builds agents, LeoSIS powers the intelligence underneath them. Each one is usable on its own — LeoSIS is not a dependency of USB.
