What it does
Loading Shimmer is an agent skill from nexu-io/motion-anything. Skeleton placeholders with a soft sweeping shimmer while content loads. Use to fill space for cards/lists/profiles that are still loading and make the wait feel shorter. Honors prefers-reduced-motion (static skeleton). Only show while real content is loading — never as decoration.
Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `recipe.motion.yaml`).
It sits in Frontend & Design. The repository describes itself as: ✨ The agentic motion layer — an open-source, chat-native motion engine. Describe the feeling; your AI ships the animation. The licence is Apache-2.0.
When your agent uses it
- Fill space for cards/lists/profiles that are still loading and make the wait feel shorter
Example prompts
- “/loading-shimmer”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Copy loading-shimmer.css and link it.
- Add data-skeleton to placeholder blocks (give each a width/height).
- Remove the placeholders (or the attribute) the moment real content arrives.
What it can do on your machine
Read from SKILL.md and the folder at commit b016900. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Loading Shimmer loads about 397 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 93 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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).
