What is create-trimble-app copilot-instructions.md?

A guide to styling Modus components with Tailwind CSS while using Modus theme colors and CSS variables. CSS variables are named values that are resolved by the browser at runtime.

Use it when adding borders, opacity, or theme-aware styling to Modus components across the available themes.

It avoids styling patterns that may use fixed colors or fail to work correctly with theme-dependent colors and opacity.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00646	$0.00646
Opus 5	$0.00323	$0.00323
Sonnet 5	$0.00129	$0.00129
Haiku 4.5	$0.00065	$0.00065

Security

Grade A, and why

create-trimble-app copilot-instructions.md 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 3d 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.

Modus React App - Copilot Instructions

React 19 + Vite boilerplate with Modus 2 Web Components (Trimble Design System). Uses TypeScript, Tailwind CSS 3, and React Router.

Commands

npm run dev          # Development server
npm run build        # Production build
npm run lint:all     # All linting checks
npm run lint:colors  # Color compliance
npm run lint:icons   # Icon validation

Design System (9 Colors Only)

Base colors: bg-background, bg-card, bg-muted, bg-secondary, text-foreground Semantic colors: bg-primary, bg-success, bg-warning, bg-destructive

NEVER use: Generic Tailwind colors (bg-blue-500, text-gray-600), hex values, or RGB.

Component Patterns

Use wrapper components from src/components/ (e.g., ModusButton, ModusAlert)
Never use ModusWc* web components directly
Use useRef + useEffect for event listeners
Let Modus components manage their own state

Critical Bugs

Checkbox value inversion - Always invert the value:

const actualChecked = !event.detail.value;

Select component - Use ModusDropdownMenu instead of ModusSelect for reliable events.

Modal pattern - Use forwardRef + useImperativeHandle. Access dialog via querySelector("dialog").

Icons

<i className="modus-icons">icon_name</i>

Only Modus icons (no Font Awesome, Material Icons)
Names use underscores: save_disk, arrow_left (not save-disk)

Styling Rules

Borders: Use border-default, border-primary, border-success

Directional: border-bottom-default (not border-b border-default)

Opacity: Use text-foreground-80 (not text-foreground/80)

CSS variables don't work with Tailwind opacity modifiers

HTML Elements: Use <div> only (no h1, p, section, span). Exception: <i> for icons.

Themes

6 themes via data-theme on <html>:

modus-classic-light, modus-classic-dark
modus-modern-light, modus-modern-dark
connect-light, connect-dark

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.
