# Batocera Yourskill

One or two sentences: what this skill covers and that it assumes the connection
pattern, filesystem model, and safety doctrine from `batocera-ops`. Cross-
reference sibling skills by name (`batocera-roms`, `batocera-display`,
`batocera-tuning`, `batocera-maintenance`) rather than repeating their content.

## Guidelines for a good Batocera skill

Delete this section in your real skill; it's guidance for authoring.

- **Name:** `batocera-<area>`, lowercase and hyphens only. The directory name
  MUST equal the frontmatter `name`.
- **Description:** starts with "Use when…", lists concrete triggers and keywords,
  ends with a "not for X, use Y" pointer. No workflow summary (an agent will
  follow the description instead of reading the body).
- **Original prose only.** Do not paste text from the Batocera wiki or other
  docs — write the lesson in your own words and link the wiki as the canonical
  manual. Ship institutional knowledge the wiki doesn't have.
- **Parameterize everything host-specific.** Use `$BATOCERA_HOST`, never a real
  IP; read passwords from env; never commit tokens, credentials, MQTT secrets,
  or personal ROM/library specifics.
- **Non-destructive doctrine.** Prefer hide/move/append over delete/overwrite;
  back up configs and gamelists before editing; never inject synthetic input.
- **Verify against ground truth.** Show the reader how to confirm the change
  (read the generated config, launch + screenshot), not just make it.
- Keep `SKILL.md` under ~500 lines. Push heavy detail into `references/*.md` and
  reusable code into `scripts/`. Scripts should be `--dry-run`-first where they
  mutate, idempotent, and self-documenting in a header.

## Overview

## [Your sections]

excellent example beats five generic ones.
