+
+## Cache Directory
+
+### repositories/
+Contains cloned copies of registered agent repositories for offline access and performance.
+
+### manifests/
+Cached manifest files from repositories for quick agent discovery.
+
+### agent-registry.json
+Central registry tracking:
+- Available agents across all repositories
+- Version information
+- Installation status
+- Dependencies

+
+## Usage
+
+The Agent Manager automatically manages this directory structure. Manual modification is not recommended but the files can be inspected for troubleshooting.
+
+For Agent Manager usage, use:
+```bash
+/agent:agent-manager <command>
+```
+
+See the main Agent Manager documentation for available commands and operations.
