Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

batocera-yourskill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
