Uber 如何构建代理系统在几分钟内自动化设计规范

The Uber Base design system serves thousands of engineers, and every component they ship depends on specs that are accurate, complete, and current. When those specs fall behind, engineering builds from assumptions instead of definitions, which causes inconsistencies and tech debt. At that scale, documentation becomes a dedicated workstream that still struggles to keep pace. This blog describes how Uber’s design systems team uses AI agents and Figma Console MCP to generate up-to-date component specs in minutes instead of weeks.

Uber Base 设计系统服务于数千名工程师，他们发布的每个组件都依赖于准确、完整且最新的规范。当这些规范落后时，工程团队就会基于假设而非定义进行构建，从而导致不一致性和技术债务。在这种规模下，文档工作成为一个专职工作流，但仍然难以跟上步伐。本博客描述了 Uber 的设计系统团队如何使用 AI 代理和 Figma Console MCP 在几分钟内而非几周内生成最新的组件规范。

uSpec is an agentic system that connects an AI agent in Cursor® to Figma® through the open-source Figma Console MCP. The agent crawls your actual component and sub-component structure, compiles that data with any additional context you provide, and generates finished spec pages directly in your Figma file in minutes. The entire pipeline runs locally, so no proprietary design data ever leaves your network—a requirement for an organization like Uber.

uSpec 是一个代理系统，它通过开源的 Figma Console MCP 将 Cursor® 中的 AI 代理连接到 Figma®。代理爬取您的实际组件和子组件结构，将其与您提供的所有附加上下文编译，并直接在您的 Figma 文件中生成完成的规范页面，只需几分钟。整个管道在本地运行，因此专有设计数据永远不会离开您的网络——这是像 Uber 这样的组织的要求。

I’ve spent years building and teaching others how to manually create component specs. At Uber, the complexity compounded in different ways: 7 implementation stacks, density variants across each, and strict accessibility requirements. The work compounds, but the process stays the same: a designer manually producing page after page of structured documentation in Figma. 

我多年来一直致力于构建并教导他人如何手动创建组件 spec。在 Uber，复杂性以不同的方式累积：7 个实现栈、每个栈的密度变体，以及严格的无障碍要求。工作量会累积，但流程保持不变：设计师在 Figma 中手动生成一页又一页的结构化文档。 

The response made clear that this wasn’t just an Uber problem. Designers and design systems leads from...
