SteamOS gives you no instructions. What firewall is running? What branch are you on? How do you set a password? What flatpaks are installed? You're left guessing or trawling forums for answers. So I built a Claude skill for SteamOS — drop Claude Code on your Steam box, and you've got an IT expert sitting on your desktop who knows the system inside out.

WHAT A SKILL IS
A Claude skill is a pre-written reference file that lives in the .claude/skills folder. It contains everything Claude needs to know about a system — how SteamOS works, flatpaks, atomic updates, special commands, branches, the lot. When you load it, Claude instantly understands your Steam box without you having to explain anything.
Mine is based on the excellent Omarchy skill file DHH ships — that's an agent file laid out so any AI landing on the system knows exactly what it's looking at and how to manage it. I took the same approach for SteamOS.
WHAT YOU CAN DO WITH IT
Load the skill and just ask. In the video I interrogate my own Steam box live:
Check the current system — it tells me I'm on SteamOS 3.9, read-only root, tracking the main branch. List the Steam branches — stable, beta, preview, main bleeding edge — and switch between them. How do passwords work — SteamOS ships with no password on the deck user, and you need one to get sudo for anything serious, so it walks you through setting one.
System commands, boot mode, atomic update controls, rolling back to a previous OS slot, firmware updates, full system reports — it explains what each one does before you run anything.
THE FIREWALL EXAMPLE
This is the useful one. SteamOS doesn't tell you what firewall it's running. I asked Claude to check and it found SSH open, everything wide open by default. It offered to lock things down — but critically it knows Steam needs certain ports open for remote play, P2P matchmaking, and content downloads, so it builds a proper ruleset instead of just slamming everything shut and breaking Steam. You learn a huge amount about the system just by interrogating it.
MEDIA SERVER
The skill also knows about a Jellyfin media server setup I've built for SteamOS that turns your Steam box into a media server alongside gaming. That's a whole separate video coming soon, but the skill already has it in its notes.
HOW TO PROMPT IT WELL
One tip that matters. Claude works best with short, concise prompts done step by step. The biggest mistake I see is people writing huge, verbose prompts dumping everything at once — I did this, then this, then that happened. Too much. Give it small, specific chunks. "Why won't this game launch?" then work through it. "My fonts are broken" then investigate. Concise questions, one at a time, and you'll get far better results.
WHY THIS MATTERS
We watch sci-fi films where an AI runs the ship. This is that, but in your control. Not the Microsoft way where it's imposed on you — you give it knowledge and it becomes genuinely helpful. An IT guy on your desktop who never gives you attitude, never makes you feel stupid, and will answer the dumbest question patiently.
I still see people on forums asking why something's broken and getting told to go read the wiki. Claude can read the wiki. It can pull the whole problem together and solve it. That's the real everyday use for AI — not summarising your email, but fixing things when they break.
THE SKILL
On Git. Drop it in your skills folder, load Claude, and start asking. Questions in the comments.
