About the project

agentOS is a library that lets software agents run inside an existing application backend, using WebAssembly and V8 isolates with controlled access to host resources. It is for developers building agent-powered backends who need embedded execution and permissions, while the catalogue entries provide skills and instructions for operating the framework.
