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 | $0.00434 | $0.00434 |
| Opus 5 | $0.00217 | $0.00217 |
| Sonnet 5 | $0.00087 | $0.00087 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
modus-angular-opacity-utilities-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.
What it actually says
Modus Opacity Utilities - Short
Essential opacity utilities for Modus Design System colors in Angular + 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 styles.css - No Tailwind config changes needed
- Respects theme switching - Works in all 6 Modus themes
- Use semantic color names -
foreground,primary,destructive, etc.
Available Utilities
Opacity Levels
- 80% -
text-foreground-80,bg-primary-80,border-destructive-80 - 60% -
text-foreground-60,bg-primary-60,border-destructive-60 - 40% -
text-foreground-40,bg-primary-40,border-destructive-40 - 20% -
text-foreground-20,bg-primary-20,border-destructive-20
Usage Examples
<!-- WRONG: Tailwind syntax doesn't work -->
<div class="text-foreground/80">Text with 80% opacity</div>
<!-- CORRECT: 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>

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.
