Atlassian's design system team tackled the problem of AI tools generating inaccurate UI by restructuring their Atlassian Design System (ADS) documentation into machine-readable schema files. These TypeScript-based schemas cover components, tokens, icons, lint rules, and accessibility requirements. The structured content powers an ADS MCP server, design system skills, and DESIGN.md files. Compared to agents working without an MCP, the approach yielded up to 52% accuracy improvement on specific queries, 34% faster task completion, 16% fewer tokens consumed, and 26% fewer tool calls. Self-healing tooling keeps documentation in sync with the codebase automatically, and the team plans to connect structured content to more agents and the Teamwork Graph.
