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.
