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.
Pi-hole installation, blocklist management, DNS-over-HTTPS setup, DHCP integration, local DNS records, and troubleshooting broken DNS resolution on a home network.
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.
Diagnose Clash proxy and network connection issues. Use this when users encounter network problems such as inability to connect to the network, proxy not working, GitHub/Google timeouts, DNS anomalies, TUN mode failures, etc.
Linux networking expert for iptables, nftables, routing, DNS, and network troubleshooting
Network architecture, troubleshooting, and infrastructure patterns. Use when designing network topologies, debugging connectivity issues, configuring load balancers, DNS, or implementing network security.
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).
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.
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
Perform Alibaba Cloud NIS (Network Intelligence Service) network path reachability analysis with forward/reverse path diagnosis, topology visualization, and resource monitoring. Use when analyzing network connectivity, diagnosing unreachable paths, checking security groups or route tables, or visualizing network topology between cloud resources. Triggers: "reachability analysis", "network path analysis", "NIS analysis", "connectivity diagnosis", "path reachable", "network troubleshooting", "可达性分析", "网络路径分析", "NIS分析", "连通性诊断", "路径可达", "网络排障".
