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.

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 | $0.00044 | $0.00662 |
| Opus 5.5 | $0.00018 | $0.00265 |
| Sonnet 5.5 | $0.00009 | $0.00132 |
| Haiku 4.5 | $0.00004 | $0.00066 |
Grade A, and why
design-system-generator 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 27d 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design System Generator
Produce a concise design system grounded in the product's actual stack and visual language. Document decisions that make future UI work consistent.
Delegation
Run in the main conversation by default. Delegation can increase usage: obtain explicit approval for the proposed agent count and scope before using subagents. Reuse that approval within its bounds; ask again before expanding the approved count or scope.
Inspect before proposing
Read existing design docs, brand references, representative screens, shared components, theme configuration, tokens, and build tooling. Infer framework, CSS approach, themes, browser support, and export formats from those sources. Ask only about unresolved product choices that materially affect the document.
Preserve an established coherent system. For a new product, recommend one suitable direction within the user's constraints; compare alternatives only when useful or requested. Do not add a component library or migrate build tooling merely to match this skill's examples.
Write the project contract
Use TEMPLATE_DESIGN_SYSTEM.md as a menu of topics. Omit inapplicable sections and replace examples with verified project decisions. Cover the relevant:
- surfaces, themes, devices, and language or RTL constraints;
- token ownership, typography, color, spacing, layout, and motion;
- shared components and the interaction states each actually supports;
- extension rules for tokens, components, utilities, and local exceptions;
- keyboard interaction, visible focus, contrast targets, semantic markup, and reduced motion;
- visual verification at comparable states and viewports;
- asset loading and cache invalidation responsibilities when the design system owns them.
Link to existing build or deployment guidance for pipeline details. Hashed filenames and manifests are one cache strategy, not a required new build system. Avoid documenting support for frameworks or themes the product does not use.
What ships with it
7 files 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.

design-system-generator is a skill published in the GitHub repository thienanblog/awesome-ai-agent-skills (70 stars, last pushed 27d ago), licensed Apache-2.0. It adds 44 tokens to every session and 662 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
