# Design Agent

A UI/UX specialist for brand, flows, and screen specs

[All agents](https://productos.dev/agents)

## What does the Design Agent do?

> “A product design specialist focused on brand identity, user flows, and UI screen specifications.”From the agent's actual system prompt

The Design Agent reads everything the earlier stages produced, the concept, the research, and the PRD, and turns it into user flows and UI screen specifications. Because it designs from the actual spec, the screens are for the product you defined, not a generic template.

It keeps your workspace in sync while it works, switching the active design tab as it moves through brand, flows, and screens, and it hands token and component-system work to the Design System Agent.

## What tools does the Design Agent use?

- `write_design_doc`
Writes brand, flow, screen, and report documents, the primary deliverable
- `get_user_flows / set_user_flows`
