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.

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 | $0.00060 | $0.00384 |
| Opus 5 | $0.00030 | $0.00192 |
| Sonnet 5 | $0.00012 | $0.00077 |
| Haiku 4.5 | $0.00006 | $0.00038 |
Grade A, and why
loading-shimmer 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.
What it actually says
loading-shimmer
Skeleton placeholders with a soft sweeping highlight. Part of
motion-anything; obeys MOTION-SPEC.md.
When to use it
- Placeholders for content still loading (cards, lists, profiles, media). Improves perceived performance.
When NOT to use it (restraint)
- Loads under ~300ms (a skeleton flash is worse than nothing). Never as pure decoration.
How to apply
- Copy
loading-shimmer.cssand link it. - Add
data-skeletonto placeholder blocks (give each a width/height). - Remove the placeholders (or the attribute) the moment real content arrives.
Accessibility & performance
prefers-reduced-motion: static skeleton, no sweep. The sweep usestransformonly (GPU-safe).
What ships with it
3 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.

loading-shimmer is a skill published in the GitHub repository nexu-io/motion-anything (762 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 60 tokens to every session and 384 once invoked, about $0.0003 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 2026-09-03.
