+OpenFlare Agent Uninstaller
+
+Usage:
+  uninstall-agent.sh [OPTIONS]
+
+Options:
+  --install-dir DIR         Installation directory (default: /opt/openflare-agent)
+  --service-name NAME       systemd service name (default: openflare-agent)
+  -h, --help                Show this help message
+
+Behavior:
+  1. Stop the agent service/process and remove the entire installation directory
+  2. Remove the systemd service definition when present
+  3. Check the saved agent config to identify the OpenResty mode
+  4. If Docker mode was used, remove the OpenResty container and try to remove its image
+  5. If local openresty_path mode was used, do not modify the local OpenResty install
+
+Examples:
+  uninstall-agent.sh
+  uninstall-agent.sh --install-dir /srv/openflare-agent
+EOF
