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 | $0.00090 | $0.03376 |
| Opus 5 | $0.00045 | $0.01688 |
| Sonnet 5 | $0.00018 | $0.00675 |
| Haiku 4.5 | $0.00009 | $0.00338 |
Grade A, and why
animated-loop 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 8d 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.

animated-loop — 3-5 Second Seamless Background Loop
A loop is the only video format that has to not have a beginning or end. The viewer sees it on the title screen for 30 seconds; if the seam between loop iterations is visible, the whole thing reads as broken. This skill exists to force the constraints that make seams invisible: keep the duration short (3-5s), keep the motion ambient (no narrative, no big camera moves), use the cheap fast model (ltx), and prompt for a composition where the first and last frames are functionally identical.
If the user wants a 5s punchy marketing shot, that's video/trailer-shot. If they want a 10s narrative cutscene, that's video/cinematic-cutscene. This skill is the one for video that has to disappear — atmosphere behind a logo, mood behind a menu, ambience behind a splash card.
When to use
- "Looping background for the title screen."
- "Animated backdrop behind the logo on the splash."
- "Menu background — torchlit dungeon, just flicker and motes."
- "Looping ambient video for the pause screen."
- "Splash loop — fog over a forest."
- "Need a video that loops behind the level select."
When NOT to use
- Marketing shot for a trailer (5-10s with punch) —
video/trailer-shot. - Narrative cutscene with a beginning and end —
video/cinematic-cutscene. - Static splash image — generate with
2d-assets/concept-artand use aTextureRect. A still is cheaper, lighter, and never seams. - UI element animation (icons, button states) — those are GDScript
Tweenor sprite sheets, not video. - A 10-second shot you want to "loop". That seam will be visible. Either accept a hard cut every 10s (ugly) or generate a 3-5s clip designed to loop.
Steps
1. Confirm the loop will be visible for a long time
Quick check — this loop will play on a screen the user might stare at for 30+ seconds. That means the loop point must be invisible. I'll keep it 3-5s and prompt for ambient motion (drift, flicker, shimmer) rather than a narrative beat. OK?
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.

animated-loop is a skill published in the GitHub repository ouzlifaneyassine1-dot/onyx-engine (0 stars, last pushed 2mo ago), licensed MIT. It adds 90 tokens to every session and 3,376 once invoked, about $0.0005 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.
