A tool that examines a website and turns its visual style into reusable design details, such as colors, fonts, logos, and layout guidance. It also saves a screenshot and the extracted details in common files.

In plain words
What is it for?
Use it to copy or adapt a website’s visual style, collect brand assets, and create design rules for a new interface.
Why use it?
It removes the need to inspect a website by hand when matching an existing brand. The results give developers a shared reference for keeping new pages visually consistent.

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 A, and why

create-design-system scanned grade A 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 9d 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.

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.
