Set up Caddy on a server so any local port is reachable at https://<port>.<domain>/, and two-letter or named labels like https://ui.<domain>/ map to ports too, with certificates issued on demand and gated so only routed hostnames get one. Use when the user says 'set up the wildcard proxy', 'port routing on this server', 'configure caddy so ports get subdomains', 'add a short name for port N', 'what port is ab', or is preparing a new server to expose local services by port.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'wildcard-proxy' ] || [ -L ~/.agents/skills/'wildcard-proxy' ]; then echo 'A skill folder named wildcard-proxy already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/koolamusic/claudefiles' "$d" && git -C "$d" checkout --quiet 'c977feefd4c9f04591f7ab26ff52babc65e85c08' -- 'skills/wildcard-proxy' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/wildcard-proxy' ~/.agents/skills/'wildcard-proxy' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'wildcard-proxy' ~/.claude/skills/'wildcard-proxy' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
