The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 39c1df0

Generated the same VLESS+Reality TUN config with and without the skill: the unguided baseline used the removed "type":"dns" outbound, globally rejected UDP 443/QUIC (an explicitly-flagged anti-pattern), and left IPv6 on by default — the skill-guided version, built from the bundled 1.13-tun template, avoided all three and correctly paired a DNS rule with the route rule for a custom "must stay direct" domain.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Sing-Box Config Generator does

Generates, migrates, and debugs sing-box client configuration files (TUN/system proxy) for v1.13 and v1.14, covering DNS/routing split rules, Clash API selectors, and node conversion for VLESS/VMess/Shadowsocks/Trojan/Hysteria2/TUIC. Triggers on sing-box, TUN/FakeIP/RealIP, DNS hijack, split routing, or client-config creation/migration/troubleshooting requests; explicitly declines server-side inbound setup.
