modus-angular-color-usage

modus-angular-color-usage is a cursor rule for Cursor from julianoczkowski/create-trimble-app. It costs 0 tokens per session (1,417 once invoked), scanned C, original, MIT.

Detailed color rules for an Angular and Vite application that uses Modus design-system colors through Tailwind CSS. They prohibit raw CSS variables, fixed hex or RGB values, and generic Tailwind color classes.

In plain words
What is it for?
Use them when writing templates or styles, selecting semantic colors, reviewing existing components, and checking that color choices follow the application’s theme rules.
Why use it?
They keep colors controlled by the design system, so themes and shared styling can change without hunting through hardcoded values.

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-color-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 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.

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.

Modus Color Usage in Angular + Vite

Design System Color Architecture

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.
