Batocera is a fantastic retro-gaming distro, but operating a cabinet day to day — curating a big library, aligning bezels, keeping the frontend fast, surviving upgrades — accumulates a pile of hard-won, wiki-doesn't-mention-it knowledge. This repo packages that knowledge as Agent Skills: focused, model-readable guides your coding agent (Claude Code and other harnesses) loads on demand when you ask it to work on your cabinet.

/plugin marketplace add t3chnaztea/batocera-skills
/plugin install batocera@t3chnaztea

The five skills

Each is a self-contained home for one area of cabinet work. Start with batocera-ops — the others assume its connection pattern, batocera.conf/configgen model, and safety doctrine.

⚠️ Read before you install

These skills direct an agent to SSH into a real machine as root and change its configuration. That is exactly as powerful as it sounds.

  • Review the skills before installing. They're plain Markdown; read what they'll do. Nothing here phones home or auto-runs — they're reference guides — but you are handing an agent an operating manual for a root shell.
  • Change Batocera's default password. Batocera ships with the well-known default root / linux. A box you SSH into as root should not keep a published password. Change it (ES → System Settings → Security, or passwd).
  • The scripts mutate real files. Every included script is --dry-run-first where it can delete, backs up configs/gamelists before editing, and is idempotent — but read the header and dry-run first anyway. They assume paths from a typical cabinet; adjust for yours.
  • Nothing here is destructive by design, and the whole doctrine is non-destructive-first (hide don't delete, back up before edit, verify against ground truth). But you own the cabinet and the risk.

Install

Claude Code plugin (recommended)

/plugin marketplace add t3chnaztea/batocera-skills
/plugin install batocera@t3chnaztea

The five skills activate automatically when your prompt matches (e.g. "my SNES bezels crop the screen", "games run slow after the update").

Manual copy (any Claude Code, no marketplace)

Copy the skill directories into your skills folder:

git clone https://github.com/t3chnaztea/batocera-skills
cp -r batocera-skills/skills/batocera-* ~/.claude/skills/

Other harnesses

Each SKILL.md is harness-neutral Markdown with standard Agent-Skills frontmatter (spec). Drop the skills/* directories wherever your agent framework discovers skills, or point it at this repo.

What's inside a skill

skills/batocera-<area>/
  SKILL.md            # the guide (frontmatter + body, < 500 lines)
  references/*.md     # heavy detail, loaded on demand
  scripts/*.py        # ready-to-adapt tools (dry-run-first, idempotent)

Skills are original prose — operational lessons, not a copy of the manual. The Batocera wiki remains the canonical reference for Batocera itself; these skills capture the parts running a cabinet teaches you that the wiki doesn't.

Contributing

Have a hard-won Batocera lesson? Copy template/SKILL.md and follow its authoring notes: original prose (no wiki paste), parameterize anything host-specific ($BATOCERA_HOST, env-var secrets), non-destructive doctrine, and show the reader how to verify the change. PRs welcome.

Companion repos

  • batocera-toolbox — a couch/gamepad-friendly on-device utility (backup, ROM audit, shader picker).
  • batocera-holidays — seasonal hide/un-hide rotation for a curated cabinet.

Versions tested

Distilled on Batocera v41–v43 on x86_64 hardware. Batocera changes across releases (path renames, service model, new systems); confirm version-specific claims against cat /usr/share/batocera/batocera.version on your box. Commands in these skills are read-only unless explicitly noted. When in doubt, the cabinet is the source of truth. So is a screenshot of it running.
