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 | $0.00704 | $0.00704 |
| Opus 5 | $0.00352 | $0.00352 |
| Sonnet 5 | $0.00141 | $0.00141 |
| Haiku 4.5 | $0.00070 | $0.00070 |
Grade A, and why
modus-opacity-utilities-solidjs-short 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 5d 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.
This is a copy
95% identical to modus-opacity-utilities-react-short — 24 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.

Modus Opacity Utilities - Short
Essential opacity utilities for Modus Design System colors in SolidJS + Vite.
Key Rules
- Use custom opacity utilities, not Tailwind /80 syntax -
text-foreground-80nottext-foreground/80 - CSS variables don't work with Tailwind opacity modifiers - Tailwind needs actual color values
- Use color-mix() for opacity variants - Modern CSS function for proper opacity calculation
- All utilities defined in index.css - No Tailwind config changes needed
- Respects theme switching - Works in all 6 Modus themes
- Use semantic color names -
foreground,primary,destructive, etc.

Usage Examples
// ❌ This doesn't work with CSS variables
<div class="text-foreground/80">Text with 80% opacity</div>
// ✅ Use custom opacity utilities
<div class="text-foreground-80">Text with 80% opacity</div>
<div class="bg-primary-60">Primary background with 60% opacity</div>
<div class="border border-destructive-40">Destructive border with 40% opacity</div>
Common Patterns
// Text hierarchy
<div class="text-foreground">Main heading (100%)</div>
<div class="text-foreground-80">Subheading (80%)</div>
<div class="text-muted-foreground-60">Description (60%)</div>
// Interactive states
<button class="bg-primary hover:bg-primary-80 transition-colors">
Hover with opacity
</button>
// Overlay effects
<div class="bg-foreground-20 absolute inset-0 rounded-lg"></div>
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.
