Kepner-Tregoe for Network Troubleshooting

What this skill is for

This skill gives a network-troubleshooting agent a disciplined method so it reaches a verified root cause before acting, instead of pattern-matching to a familiar cause and swapping components. The entire value is sequencing and separation: appraise before diagnosing, specify before theorizing, verify before fixing, decide before acting, protect before executing.

You will usually have tools that can read network state (telemetry, device configs, routing/ARP/session tables, logs, packet/flow data, inventory/CMDB). Use those tools to gather the evidence that fills the specification — do not reason from memory when you can observe. The method tells you which evidence matters and what to conclude from it.
