Use this skill when writing or reviewing Python automation that connects to network devices with Netmiko. Keep the default path read-only; config changes need a separate change window, peer review, and rollback plan. Collecting show command output across routers, switches, or firewalls. Building a small audit script for interface, routing, or config evidence. Adding timeouts and exception handling to network SSH scripts. Parsing command output with TextFSM when a template exists. Reviewing automation before it touches production devices. Start with read-only sendcommand() collection. Keep inventory small and explicit; do not sweep whole address ranges. Use environment variables, a vault, or getpass; never hardcode credentials. Set connection and read timeouts. Limit concurrency so older devices are not overloaded. Require an explicit operator flag before sendconfigset(). Do not call saveconfig() until the change has been verified and approved. Use placeholder addresses from documentation ranges in examples. Keep real inventory in an ignored local file or a secrets-managed system. Keep maxworkers low unless the device estate and AAA systems are known to handle higher connection volu
