Provision new NixOS servers on Proxmox for this nix flake project. Guides through the complete workflow: creating Proxmox LXC containers, SSH setup, Colmena configuration (init/full pattern), and application deployment with nginx proxy, PostgreSQL, and container images. Use when: (1) Creating a new server/container on Proxmox, (2) Setting up a new NixOS host with Colmena, (3) Deploying applications with nginx SSL proxy and/or PostgreSQL database, (4) Adding new container images to the repository.
Expert knowledge for Azure Osconfig development including troubleshooting, security, configuration, and integrations & coding patterns. Use when running OSConfig via IoT Hub for commands, SSH posture, agent health, Windows baselines, or LAPS, and other Azure Osconfig related development tasks. Not for Azure Update Manager (use azure-update-manager), Azure Automation (use azure-automation), Azure Policy (use azure-policy).
Tmux execution support for long-running and persistent commands. Load this skill when you need to: (1) run commands expected to exceed tool timeout (over 60s), (2) start persistent servers or dev processes, (3) run TUI/interactive applications, (4) execute parallel isolated tasks in separate sessions, (5) run remote commands over SSH that must survive disconnection, (6) handle tmux errors like 'capture-pane blocked in interactive_bash'. Trigger phrases: 'run in background', 'start server', 'long-running', 'tmux session', 'keep running', 'persistent process', 'dev server', 'training script', 'git clone large repo', 'docker build', 'capture-pane blocked'.
