network-config-validation
Pre-deployment checks for router and switch configuration
by affaan-mFree
Description
network-config-validation is an agent skill from the ECC collection by affaan-m, listed on skills.sh. It runs pre-deployment checks on router and switch configuration before a change window, or before an automation run touches production devices. It looks for dangerous commands, duplicate IP addresses, subnet overlaps, and stale references, such as ACLs, route maps, prefix lists or line policies that are referenced but never defined. It applies when reviewing Cisco IOS or IOS-XE style snippets, auditing configuration generated by scripts or templates, and building lightweight pre-flight scripts for network automation. The skill treats validation as layered evidence rather than a full parser. Its regex checks are useful as warnings, but the listing says a network engineer still has to review intent, platform syntax and the rollback steps before anything is approved. A skill is a SKILL.md file of instructions that an AI agent loads when a task calls for it. It is free and open source, and the skills.sh listing shows a Snyk fail, with Gen Agent Trust Hub and Socket passing.…
