    Example session with this skill installed

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

    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.

    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.

    Supported Tools

    • Web: NginX, Cloudflared Tunnels
    • System: Systemd, Netstat/SS, df/du
    • Database: PostgreSQL
    • Security: Linux Permissions, .env audit

    • Cannot fix issues automatically (read-only by design).
    • Requires Python 3 and local shell access.
    • Does not support Docker container internal networking audits.

    Frequently Asked Questions

    No, this skill is strictly read-only. It identifies the root cause of service failures and provides you with the exact command to fix it manually, ensuring you maintain full control over your server configuration.

    This skill is optimized for Linux-based environments, including Raspberry Pi (Debian/Ubuntu), and supports diagnostic checks for Nginx, Cloudflare Tunnels, systemd, and PostgreSQL databases.

    Env Doctor automates the 'triage' phase of troubleshooting, instantly spotting common issues like port conflicts, disk space exhaustion, and permission errors that usually take hours of manual log-checking to find.

    Setup is minimal; once the skill is added to your AI agent, you simply provide the agent with the necessary read access to your terminal or logs to begin the diagnostic scan.

    Your purchase includes the full diagnostic engine, all current service modules (Nginx, Systemd, etc.), and lifetime access to any future logic updates or new service modules added to the skill.
