Optimize Network

Use this skill to run a safe, evidence-first network optimization workflow. The default posture is read-only diagnosis, then small reversible experiments, then before/after verification. Never treat VPN, proxy, TUN, or routing tools as junk processes.

Safety Contract

Follow these rules before any command that could affect connectivity:

• Intent lock: the goal is speed, latency, responsiveness, and stability, not cleaning network configuration.
• Proxy/VPN protection: do not stop, restart, unload, delete, reconfigure, or bypass Clash, Mihomo, Shadowrocket, Tailscale, V2Ray, Surge, WireGuard, OpenVPN, corporate VPNs, or their TUN interfaces unless the user explicitly requests that exact operation.
• Default read-only: diagnostics may run directly; changes require a short proposal with risk, rollback, and expected effect.
• Reversible first: prefer temporary A/B tests, service reordering, DNS experiments, cache flushes, and user-confirmed app closure over deletion.
• No silent degradation: if a change breaks access to AI tools, proxy, remote work, DNS, or LAN devices, revert it or report the blocker immediately.
• No destructive cleanup: do not delete network locations, profiles, VPN configs, proxy configs, launch agents, routes, or firewall rules. If deletion looks useful, propose disable/dry-run first.
• Sudo caution: any sudo, interface down/up, DHCP reset, route change, or network service disable must be confirmed by the user first.
• Remote session caution: if the user may be connected through SSH, remote desktop, RustDesk, Tailscale, or VPN, ask before any change that could disconnect them.
