SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Slow internet, high latency, and unstable connections are hard to troubleshoot without a structured process, and blind changes to DNS, MTU, or VPN settings often make things worse. This Skill performs read-only network diagnostics first, produces an evidence-based report, and only applies optimizations after explicit user approval. ## Core Features & Use Cases - Read-Only Diagnostics: Inspects network interfaces, routes, DNS, proxy, VPN, MTU, Wi-Fi signal strength, packet loss, and latency without modifying any settings. - Evidence-Based Report: Ranks each issue with evidence, expected improvement, risk level, and a list of things that should not be changed. - Approval-Gated Optimization: Executes only user-approved changes one at a time, then runs before/after verification of DNS resolution time, ping, packet loss, and speed tests. - Use Case: Your video calls keep stuttering and pages load slowly while connected to a VPN. The Skill measures DNS query times across system, router, and VPN DNS, checks Wi-Fi SNR and channel interference, identifies the VPN as the latency source, and proposes non-VPN alternatives before touching anything. ## Quick Start Run a full network check on this machine, diagnose what is slowing down my connection, and give me a report before changing anything.

FAQPage Schema
How do I diagnose slow internet speed on my computer?

Run read-only checks on network interfaces, DNS resolution time, packet loss, latency, and Wi-Fi signal strength before changing anything. This Skill performs that full inspection and produces a ranked diagnostic report with evidence for each issue.

How to test if a VPN is causing high latency or slow DNS?

Compare DNS resolution times across system, router, and VPN DNS servers, and measure latency with and without VPN routes. The Skill detects VPN usage and, if it is the bottleneck, proposes alternatives that keep the VPN functional.

Does this Skill change my network settings automatically?

No. It never modifies DNS, MTU, profiles, VPN, or background processes without explicit approval. Every optimization is listed first, executed one at a time after consent, and verified with before/after measurements.

Can network optimization break my VPN connection?

It can if done blindly, which is why this Skill treats VPN availability as a hard constraint. It will not close, switch, or reconfigure the VPN unless you explicitly approve, and it offers non-VPN workarounds when the VPN is the bottleneck.

What metrics verify that a network optimization actually worked?

DNS resolution time, ping latency, packet loss, Wi-Fi signal status, and optionally speedtest or networkQuality results. The Skill re-measures each metric after changes and reports which items improved, which did not, and whether to keep or revert them.
