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 | $0.00082 | $0.02848 |
| Opus 5.5 | $0.00033 | $0.01139 |
| Sonnet 5.5 | $0.00016 | $0.00570 |
| Haiku 4.5 | $0.00008 | $0.00285 |
Grade A, and why
modus-frontend 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This skill guides creation of production-grade frontend interfaces using the Modus 2.0 Design System. All output must strictly follow the design system constraints below. The result should be polished, professional, enterprise-grade UI that is fully theme-compatible and design-system compliant.
The user provides frontend requirements: a component, page, dashboard, or interface to build. They may include context about the purpose, audience, or technical constraints.
Design Thinking
Before coding, understand the context:
- Purpose: What problem does this interface solve? Who uses it? (field workers, office managers, engineers, administrators)
- Layout: What layout pattern fits? (sidebar + content, top nav + grid, full-width dashboard, split pane, card grid)
- Information hierarchy: What's most important? Use font size scale, color weight, and spacing to guide the eye.
- Theme compatibility: Will this look correct in both light and dark themes? Never hardcode colors.
The Modus design system philosophy is clean, consistent, and professional. Express creativity through thoughtful layout composition, smart use of the 9-color system with opacity variants, precise spacing, and clear visual hierarchy - not through custom fonts, wild color palettes, or decorative flourishes.
9-Color Semantic System
ALL colors must come from these 9 semantic tokens. No exceptions.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
