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 | $0.00110 | $0.01262 |
| Opus 5 | $0.00055 | $0.00631 |
| Sonnet 5 | $0.00022 | $0.00252 |
| Haiku 4.5 | $0.00011 | $0.00126 |
Grade A, and why
loading-page-design 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.

Loading Page Design Skill
Design beautiful, performant loading pages that provide excellent user experience while users wait for content to load.
Core Principles
1. Set Clear Expectations
Users should always know:
- Something is happening
- How long they might wait (if predictable)
- What is being loaded
2. Keep It Engaging
- Use smooth, purposeful animations
- Show branded visual elements
- Provide feedback through progress indicators
3. Performance First
- Loading page itself must load fast
- Use CSS animations over JavaScript where possible
- Keep the loading UI lightweight
Loading Page Types
Full Page Loader
Covers the entire viewport during initial page load. Best for:
- Critical path loading
- App initialization
- Heavy content pages
Skeleton Screen
Shows a wireframeplaceholder structure of content loading. Best for:
- Feed/list content
- Card-based layouts
- Dynamic data tables
Inline Loader
Small indicator within existing content. Best for:
- Button loading states
- Form submissions
- Section refreshes
Progress Bar
Shows percentage or steps complete. Best for:
- File uploads/downloads
- Multi-step processes
- Known-duration operations
Animation Guidelines
Spinner Animations
/* Classic rotating spinner */
@keyframes spin {
to { transform: rotate(360deg); }
}
/* Pulsing dots */
@keyframes pulse {
0%, 100% { opacity: 0.4; }
50% { opacity: 1; }
}
Skeleton/Shimmer Effect
@keyframes shimmer {
0% { background-position: -200% 0; }
100% { background-position: 200% 0; }
}
.skeleton {
background: linear-gradient(
90deg,
#f0f0f0 25%,
#e0e0e0 50%,
#f0f0f0 75%
);
background-size: 200% 100%;
animation: shimmer 1.5s infinite;
}
Progress Bar
@keyframes progress {
0% { width: 0%; }
100% { width: var(--progress, 100%); }
}
Design Patterns
Pattern 1: Minimal Dot Spinner
- 3-4 dots in a row
- Sequential pulse animation
- Subtle, non-distracting
- Use case: Inline loading, small spaces
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-page-design is a skill published in the GitHub repository xyzbit/claude-plugins (27 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 110 tokens to every session and 1,262 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 2026-08-30.
