Systematic, safety-first diagnosis of developer network failures such as connection refused, DNS resolution errors, TLS certificate problems, proxy failures, and package registry timeouts. Use when a command fails with a network-shaped error (curl, npm, pip, git, docker), when a service is unreachable, or when the user asks to debug connectivity, DNS, TLS, or proxy issues.
Diagnose and resolve Ludus deployment, networking, template, WireGuard, Proxmox, and Ansible issues. Use when users report failures, errors, unreachable systems, failed joins, or unexpected behavior during build or deploy.
Use this skill when diagnosing, configuring, or monitoring NICs for AF_XDP / XDP workloads. Covers driver detection, hardware queue configuration, offload control (GSO/GRO/TSO/LRO), VLAN offloads, Flow Director (FDIR) rules, CPU core pinning and NUMA awareness, hardware queue and drop monitoring, BPF program inspection with bpftool, kernel tracing via ftrace, perf profiling and flamegraphs, IRQ-to-queue-to-core mapping, and a quick diagnostic checklist.
Investigates Google Cloud networking issues by analyzing logs, metrics, and diagnostics. Use when investigating VPC Flow Logs, NAT, firewall, or threat logs, querying latency and throughput metrics, or running Connectivity Tests for path diagnostics.
Linux networking expert for iptables, nftables, routing, DNS, and network troubleshooting
This skill should be used when the user asks to "analyze network traffic with Wireshark", "capture packets for troubleshooting", "filter PCAP files", "follow TCP/UDP streams", "dete...
Evidence-driven investigation for network, streaming, and protocol-layer bugs. Use when debugging connection resets (ECONNRESET, HTTP/2 RST_STREAM, INTERNAL_ERROR), SSE or long-polling stalls, fixed-time connection drops, CDN/proxy/CGNAT idle timeouts, or any incident where symptoms do not match the obvious cause. Applies falsification-first methodology — layered isolation experiments to pin down the responsible network layer, env-gated runtime instrumentation for non-invasive observation, and counter-review agent teams to challenge single-cause assumptions. Strongly trigger on "socket closed unexpectedly", "stream interrupted", "ECONNRESET", "HTTP/2 INTERNAL_ERROR", "fails after N seconds", "works sometimes but not always", "upstream silent for X seconds", or any scenario where the investigator might jump to conclusions before evidence. Generalizes to any multi-layer system investigation where assumption-first thinking is the failure mode.
Guidance for setting up QEMU virtual machines with Alpine Linux and SSH access. This skill should be used when tasks involve starting QEMU with Alpine Linux ISO, configuring port forwarding for SSH, setting up OpenSSH server in Alpine, or troubleshooting QEMU networking issues.
Expert knowledge for Azure Networking development including troubleshooting, best practices, decision making, architecture & design patterns, security, and integrations & coding patterns. Use when designing VNets/hubs, routing via firewalls/gateways, enforcing Policy, or querying networks with Resource Graph, and other Azure Networking related development tasks. Not for Azure Virtual Network (use azure-virtual-network), Azure Virtual Network Manager (use azure-virtual-network-manager), Azure Virtual WAN (use azure-virtual-wan), Azure Network Watcher (use azure-network-watcher).
Auto-detect network issues and force proxy usage with proxychains4. Use this skill when encountering connection timeouts, DNS failures, or blocked network access. Default proxy is http://127.0.0.1:9910
Expert knowledge for Azure Network Watcher development including troubleshooting, decision making, limits & quotas, security, configuration, and integrations & coding patterns. Use when configuring Connection Monitor, NSG/VNet flow logs, Traffic Analytics/KQL, packet capture, or Sentinel integration, and other Azure Network Watcher related development tasks. Not for Azure Monitor (use azure-monitor), Azure Networking (use azure-networking), Azure Virtual Network (use azure-virtual-network), Azure Virtual Network Manager (use azure-virtual-network-manager).
Network architecture, troubleshooting, and infrastructure patterns. Use when designing network topologies, debugging connectivity issues, configuring load balancers, DNS, or implementing network security.
