## About HOL Guard
HOL Guard is an Apache-2.0-licensed runtime-control tool for supported agent integrations. It evaluates covered actions against configured policy and records decisions; coverage depends on the harness and event surface. A public repository, release and Python package were available during review. Local functionality is separate from optional paid cloud features. No interception, scan or protection guarantee was tested.
