What it does

• pt_plan_topology: Generates a complete validated topology plan including devices and links.
• pt_live_deploy: Streams commands directly to a running Packet Tracer instance via an HTTP bridge.
• pt_full_build: All-in-one pipeline that plans, validates, and generates a human-readable report.
• pt_apply_acl: Applies standard, extended, or named ACLs to live routers.
• pt_apply_nat: Configures Static NAT, Dynamic NAT, or PAT on live routers.
• pt_install_modules_batch: Installs expansion modules (HWIC, NIM, NM) on routers.
