modus-angular-border-usage

A set of rules for choosing borders in an Angular and Vite application that uses the Modus Design System, a shared set of interface components and styles.

In plain words
What is it for?
Use it when adding or changing borders in Angular templates so they follow the Modus Design System conventions.
Why use it?
It prevents inconsistent borders by requiring the project's design-system utilities instead of generic Tailwind classes or inline styles.

Token cost

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.

Security

Grade C, and why

modus-angular-border-usage scanned grade C with 1 finding 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 2d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Border Usage Guidelines - Modus Design System (Angular)

CRITICAL: Use Design System Border Utilities

When working with borders in this Angular + Vite app, always use custom design system border utilities instead of Tailwind color classes or inline styles.

NEVER Do These

1. Tailwind Color Classes in Borders

<!-- WRONG: Tailwind color classes -->
<div class="border border-red-500">Error message</div>
<div class="border-2 border-green-500">Success message</div>
<div class="border border-blue-500">Info message</div>
<div class="border border-yellow-500">Warning message</div>

2. Inline Border Styles

<!-- WRONG: Inline styles -->
<div [style.border]="'1px solid var(--border)'">Content</div>
<div [style.border]="'2px solid var(--modus-wc-color-success)'">Content</div>

3. Generic Tailwind Border Classes

<!-- WRONG: Generic Tailwind classes -->
<div class="border border-gray-300">Content</div>
<div class="border-2 border-slate-400">Content</div>

ALWAYS Do These

1. Use Design System Border Utilities

<!-- CORRECT: Design system utilities -->
<div class="border-default">Default border</div>
<div class="border-success">Success border</div>
<div class="border-warning">Warning border</div>
<div class="border-destructive">Error border</div>
<div class="border-primary">Primary border</div>

2. Use Thick Border Utilities for Emphasis

<!-- CORRECT: Thick borders for emphasis -->
<div class="border-thick">Default thick border</div>
<div class="border-thick-success">Success thick border</div>
<div class="border-thick-warning">Warning thick border</div>
<div class="border-thick-destructive">Error thick border</div>
<div class="border-thick-primary">Primary thick border</div>

3. Use Directional Border Utilities

<!-- CORRECT: Directional borders -->
<div class="border-top-default">Top border only</div>
<div class="border-bottom-default">Bottom border only</div>
<div class="border-left-default">Left border only</div>
<div class="border-right-default">Right border only</div>

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.
