What is marquee-loop?

A layout and animation pattern for a seamless, continuously moving row of duplicated items.

Use it to create infinite marquees with stable item widths, edge masking, hover controls, and reduced-motion behavior.

It prevents visible jumps when logos, tags, testimonials, screenshots, or feature chips loop across a page.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00013	$0.00174
Opus 5	$0.00006	$0.00087
Sonnet 5	$0.00003	$0.00035
Haiku 4.5	$0.00001	$0.00017

Security

Grade A, and why

marquee-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 4d 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.

Origin

This is a copy

100% identical to marquee-loop — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Marquee Skill

Use When

A design needs a seamless infinite loop for logos, testimonials, screenshots, tags, or short feature chips.

Workflow

Duplicate the item sequence so the end and beginning match perfectly.
Animate the track with a linear transform from 0 to -50%.
Keep item widths stable to prevent jumps during the loop.
Mask or fade the edges when the marquee enters or exits a section.
Pause or slow the marquee on hover only when interaction is useful.
Respect prefers-reduced-motion with a static wrap or very slow movement.

Guardrails

Do not animate unique content that users must read carefully.
Do not use large CPU-heavy shadows or filters on every moving item.

Files

What ships with it

12 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.

Changes

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.
