Design Spec
UX specs before code, grounded in your product
Generates comprehensive UX specifications covering flows, states, edge cases, and interaction details — grounded in your existing product and design system.
How it works
Describe the feature
Share what you want to build. The agent reads your codebase and design system to understand the existing context.
Generate the spec
The agent produces a detailed UX specification covering user flows, component states, edge cases, and interaction patterns.
Refine and align
Review and iterate on the spec with the agent until it fully captures the intended experience.

Why use Design Spec
Grounded in your product
Specs reference your actual components, patterns, and conventions — not generic templates.
Edge cases covered
The agent systematically identifies empty states, error states, loading states, and boundary conditions.
Faster alignment
A comprehensive spec reduces back-and-forth between design and engineering during implementation.
Living documentation
Specs stay in your codebase and evolve with your product rather than rotting in a wiki.
When to use Design Spec
New feature specification
You need to spec out a new feature before prototyping begins.
Write a UX spec for adding team workspaces to our app. Cover permissions, invitations, and billing implications.
Redesign documentation
You are redesigning an existing flow and need to document every state and transition.
Spec out the redesigned checkout flow. Include every form state, validation rule, and error message.
Cross-platform consistency
You need to ensure a feature works consistently across web and mobile.
Write a spec for our notification preferences that covers web, iOS, and Android differences.
