Skills for Designers and Engineers is 17 folders of Markdown — no code at all — by
Emil Kowalski, a design engineer who spent years at Vercel and Linear and wrote two of
the React libraries a lot of teams already ship (Sonner, Vaul). The files give an agent the
calls he makes about motion: what should not animate at all, which curve belongs on an
entrance, when a spring should bounce and how far.
The reason it earns the first slot is not the install count. It is that the strongest files
are subtractive. One tells the agent that a control used a hundred times a day should never
animate, ever. Another exists to delete motion that cannot defend itself. A third lets the
agent answer a request by writing zero lines of code — and calls that a success.
That is the bias worth curating for. Agents are already fluent at producing more. A skill
that knows when to stop is rarer, and worth more.
The best file in the set is the one that tells the agent to write nothing at all.
