network-interface-health
Diagnose interface errors, drops, CRCs, duplex mismatches, flapping
by affaan-mFree
Description
network-interface-health is an agent skill from the ECC collection by affaan-m, listed on skills.sh. It diagnoses problems on the physical side of a network: interface errors, drops, CRC errors, duplex mismatches, flapping links, speed negotiation issues and counter trends on routers, switches and Linux hosts. It applies when a network symptom may come from a cable, transceiver, switch port, duplex setting or congested interface, when a host or VLAN shows packet loss, latency spikes or intermittent reachability, when an interface reports CRCs, runts, giants, drops, resets or flaps, when both ends of a link need comparing before hardware is replaced, and when monitoring reports rising interface error or discard counters. The method is to capture a baseline, wait a measurement interval, capture again, and compare the increments, since the trend matters more than the absolute number. 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 all three security audits passing.…
