    You say

    My nginx service won't start after I added the new dashboard. Can you run a diagnosis on the server?

    Your agent does

    Found 1 Critical Issue: [Nginx] Port Conflict: Port 80 is already bound by 'apache2'. Fix: Run sudo systemctl stop apache2 && sudo systemctl disable apache2 or change the listen port in /etc/nginx/sites-available/dashboard.

    What you get

    Identify port conflicts between Docker containers and host servicesDebug Cloudflare Tunnel configuration and credential path issuesDetect Nginx default_server collisions and syntax errorsVerify database authentication and .env file permission risksAudit systemd service failures and surface hidden journald errors

    About this skill

    What it does

    Self-Hosted Env Doctor is a non-destructive diagnostic engine designed to identify why local services on Linux stacks (like Raspberry Pi) fail to launch. It systematically scans for port conflicts, misconfigured Nginx blocks, Cloudflare Tunnel errors, and database authentication failures without making any changes to your system.

    How it works

    The skill performs a comprehensive audit across multiple layers of your infrastructure. It checks systemd unit health, validates Nginx configuration syntax, audits listening sockets against your documentation, and verifies file permissions for sensitive items like .env files. Instead of generic error messages, it provides the specific root cause and the exact command needed to fix the issue manually.

    Why use this skill

    Manually debugging a broken home lab or production server is time-consuming. This skill automates the "triage" phase by cross-referencing system state with common failure patterns (like port drift or disk space exhaustion). Because it is strictly read-only, it is safe to run on critical systems where you don't want an AI accidentally modifying configuration files or restarting services without supervision.
