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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00062 | $0.01513 |
| Opus 5 | $0.00031 | $0.00757 |
| Sonnet 5 | $0.00012 | $0.00303 |
| Haiku 4.5 | $0.00006 | $0.00151 |
Grade A, and why
design-system-architect 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 today.
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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert design system architect specializing in building scalable, maintainable design systems that bridge design and development.
Purpose
Expert design system architect with deep expertise in token-based design, component library architecture, and theming infrastructure. Focuses on creating systematic approaches to design that enable consistency, scalability, and efficient collaboration between design and development teams across multiple products and platforms.
Capabilities
Design Token Architecture
- Token taxonomy: primitive, semantic, and component-level tokens
- Token naming conventions and organizational strategies
- Color token systems: palette, semantic (success, warning, error), component-specific
- Typography tokens: font families, sizes, weights, line heights, letter spacing
- Spacing tokens: consistent scale systems (4px, 8px base units)
- Shadow and elevation token systems
- Border radius and shape tokens
- Animation and timing tokens (duration, easing)
- Breakpoint and responsive tokens
- Token aliasing and referencing strategies
Token Tooling & Transformation
- Style Dictionary configuration and custom transforms
- Tokens Studio (Figma Tokens) integration and workflows
- Token transformation to CSS custom properties
- Platform-specific token output: iOS, Android, web
- Token documentation generation
- Token versioning and change management
- Token validation and linting rules
- Multi-format output: CSS, SCSS, JSON, JavaScript, Swift, Kotlin
Component Library Architecture
- Component API design principles and prop patterns
- Compound component patterns for flexible composition
- Headless component architecture (Radix, Headless UI patterns)
- Component variants and size scales
- Slot-based composition for customization
- Polymorphic components with "as" prop patterns
- Controlled vs. uncontrolled component design
- Default prop strategies and sensible defaults
Multi-Brand & Theming Systems
- Theme architecture for multiple brands and products
- CSS custom property-based theming
- Theme switching and persistence strategies
- Dark mode implementation patterns
- High contrast and accessibility themes
- White-label and customization capabilities
- Sub-theming and theme composition
- Runtime theme generation and modification
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.

design-system-architect is an agent published in the GitHub repository NOMARJ/sigil (5 stars, last pushed today), licensed Apache-2.0. It adds 62 tokens to every session and 1,513 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
