Specra

Specra converts reference screenshots into a structured DESIGN.md file, accompanying theme.css, and MCP workflows that serve as a design context for AI coding agents such as Codex and Claude. By extracting tokens, patterns, and implementation guidance from the visual source, it creates a production‑ready design system that agents can query while generating or refining UI components, reducing drift from the original design.

The tool is aimed at developers and teams that employ AI assistants to build user interfaces and want the generated code to stay aligned with an existing visual design. It offers plugins and skills that let agents evaluate UI output against the extracted specifications, request follow‑up changes, and iterate within real coding sessions.

What distinguishes Specra is its focus on a “design context layer” that supplies explicit constraints and reusable files rather than relying on agents to infer design solely from code. This enables more cohesive, consistent UIs and less post‑generation cleanup.
