Network Config Validation

Use this skill to review network configuration before a change window or before
an automation run touches production devices.

When to Use

Reviewing Cisco IOS or IOS-XE style snippets before deployment.

Auditing generated config from scripts or templates.

Looking for dangerous commands, duplicate IP addresses, or subnet overlaps.

Checking whether ACLs, route-maps, prefix-lists, or line policies are referenced
but not defined.

Building lightweight pre-flight scripts for network automation.

How It Works

Treat config validation as layered evidence, not as a complete parser. Regex
checks are useful for pre-flight warnings, but final approval still needs a
network engineer to review intent, platform syntax, and rollback steps.
