Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00116 | $0.01802 |
| Opus 5 | $0.00058 | $0.00901 |
| Sonnet 5 | $0.00023 | $0.00360 |
| Haiku 4.5 | $0.00012 | $0.00180 |
Grade A, and why
batocera-display 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 11d 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Batocera Display
Shaders, bezels, and display mode — everything about how the picture looks.
Assumes the connection pattern, batocera.conf/configgen model, and verify loop
from batocera-ops. Because display changes are visual, the
batocera-ops remote verify loop (ES HTTP API launch + batocera-screenshot)
is your primary tool here: never declare a shader or bezel "working" from the
config alone — launch it and look.
Shaders
Shaders are assigned per-system (or per-game) in batocera.conf. Two key
mechanisms and the traps around each.
shaderset resolves against TWO search paths
<system>.shaderset=<name> is a folder-name lookup resolved against both:
/userdata/shaders/configs/<name>/(user-installed)/usr/share/batocera/shaders/configs/<name>/(system-bundled)
Checking only one path is enough to wrongly declare a preset invalid. Some
built-in names are aliases that resolve to a preset deep under
/usr/share/batocera/shaders/. Before concluding a shaderset value is dead:
SSHB "find /userdata/shaders /usr/share/batocera/shaders -maxdepth 3 -iname '<name>*'"
And read the launch log for the shader actually used on the last launch — it is authoritative:
SSHB "grep -i 'set-shader\|shader' /userdata/system/logs/es_launch_stdout.log | tail"
Two shader keys: shaderset vs -renderer.shader
<system>.shaderset=<name>— a Batocera shaderset folder (may bundle bezel art, e.g. Koko-AIO/Duimon presets).<system>-renderer.shader=<path>— a direct RetroArch.slangppath (relative to the shaders dir, or absolute). This is how you assign a plain CRT preset likecrt/crt-super-xbror a custom.slangp.
Per-game overrides use the exact-filename key from batocera-ops →
batocera-conf: snes["Super Mario World (USA).sfc"]-renderer.shader=.... A glob
(snes["Star Fox*"]...) never matches.
Anti-moiré: integer scaling is impossible inside a custom-viewport bezel
A CRT mask shader (crt-royale and friends) can produce rainbow moiré when the
game isn't integer-scaled. The usual cure — video_scale_integer — is ignored
for a custom viewport, and bezels that force a custom RetroArch viewport (with
fractional coordinates) put you exactly there. So you cannot integer-scale inside
those bezels.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

batocera-display is a skill published in the GitHub repository t3chnaztea/batocera-skills (4 stars, last pushed 19d ago), licensed MIT. It adds 116 tokens to every session and 1,802 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
