Find which layer of a self-hosted Portal relay is failing - container and process, open ports, embedded DNS and NS/glue delegation, DNSSEC and the parent DS, TLS and SNI routing, the QUIC UDP backhaul and TCP/UDP lease ports, or approval and source policy - with bounded read-only checks, then report the cause and the fix.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'portal-relay-diagnose' ] || [ -L ~/.agents/skills/'portal-relay-diagnose' ]; then echo 'A skill folder named portal-relay-diagnose already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gosuda/portal-tunnel' "$d" && git -C "$d" checkout --quiet '88d645739fdb59c7f19ce583db42d27b9ca6a3be' -- 'plugins/portal-relay/skills/portal-relay-diagnose' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/portal-relay/skills/portal-relay-diagnose' ~/.agents/skills/'portal-relay-diagnose' && 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/'portal-relay-diagnose' ~/.claude/skills/'portal-relay-diagnose' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
