Audit frontend logic with Claude Code

Running designs through the terminal requires a strict feedback loop. The `prove_design` tool gives your CLI agent a way to check its work against a set of design constraints. It catches the 'AI startup' look before you commit. You save time by forcing the agent to get the layout right on the first pass.

Programmatic design validation

This server acts as a gatekeeper for your UI components. It forces the agent to define color choices and spacing rules as part of the build process. You aren't just writing code; you are documenting the design intent. This makes your CI/CD pipeline much more reliable for frontend changes.

Control typography from the CLI

Claude Code can handle complex tasks, but it needs guidance on visual hierarchy. This tool forces it to map out exact font weights and sizes. You ensure that the output isn't just functional but also visually distinct. It turns your terminal workflow into a design-led process.
