Individual skill

optimize-network

Safely diagnose and improve local network speed, latency, jitter, DNS, Wi-Fi, Ethernet, macOS network services, and bufferbloat. Use this skill whenever the user asks to optimize internet/network speed, make the network faster, diagnose slow Wi-Fi, latency, packet loss, DNS delay, unstable Codex/AI tool connectivity, or asks about the viral Codex network optimization workflow. Always protect VPN/proxy tools such as Clash Verge, Mihomo, Shadowrocket, Tailscale, V2Ray, Surge, and corporate VPNs; do not modify or disable them unless the user explicitly asks for that specific change.

# 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.
