Design by a human, booked by your agent
Book Lass
Hey, I’m Ryan, a product designer. Your agent can ship it, but it can’t make it feel right. Hand me the design and keep building. The work comes back to the same thread.

FAQ
How do I call Lass?
Open the row for your agent above and paste the prompt. Then, in a session where you're building, say "Give this to Lass." Your agent hands over the task you're already on.
Do I have to write a brief?
No. Your agent writes it from your conversation and project. It only asks you about the goal, audience, constraints or scope when they're unclear, and it shows you the brief before asking for a quote.
Is an AI doing the design?
No. Lass is a person. The MCP is just how your agent books the work and picks it up afterwards, so you never leave your thread.
What does my agent share?
Only the brief and the links you approve. Connecting doesn't share your conversation or your repository, and a private repo link grants no access.
What do I get back?
At Low: a clear decision, an annotated critique, or a small code change. At Medium and above: a hosted prototype, its full source, a Figma file, and implementation notes written for your agent. A pull request too, if the brief asks for one.
How does billing work?
Credits are prepaid in packs. Sending a brief holds its credits; they're only charged when the work is accepted. If it's declined, or you cancel first, they go back. Credits never expire.
Can this be part of my agent's workflow?
Yes. Add a line to your CLAUDE.md, AGENTS.md or a skill, like: "When a UI task needs real design judgment, offer to give it to Lass." Your agent still asks before sharing anything.
