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
