A single source of truth for the Intuit Design System, by AI, for AI and humans. Fifteen months from sprint to shipped.
Docs in one repo, components in another, tokens in a Figma library, contribution rules in Coda. The starting point depended on who you asked. Around 70% of designers were dissatisfied with our existing developer documentation.
That shift changed everything downstream. How we wrote, how we structured, how we stored content. The bet wasn't a better doc site. The bet was authoring for both audiences from one source. Markdown, in one GitHub repo.
With zero engineers, $0 budget, and an on-prem requirement, the project hit a hard stop in November 2025. Then Claude arrived inside Intuit, and the economics of the project changed rapidly. A durable POC, built one prompt at a time.
Architecture, content modelling, accessibility review, and stakeholder writing.
Inline edits, refactors, repo orientation, and paired writing of every file.
Lifted last year's designs into the new build without redrawing.
A coordinated launch. Visual refresh, brand foundations, migration paths, and refreshed docs using MDX. Built using our own IDS components and patterns
Amrit shipped visual rigor I wouldn't have. The hardest part was resisting the urge to take the repo back.
Every "no" wasn't a setback. It was a chance to sharpen our strategy.
AI didn't replace the engineers we didn't have. It made one designer cheap enough to bring eng a POC worth landing.
The markdown in one repo bet held every time a UI decision wobbled. Architecture decisions compound.
Where there were 9+ scattered surfaces before.
reduction in slack support due to self-serve measures.
DAU. Engagement was through the roof.
Built and maintained using existing resources: Our design team, Claude & Cursor
Documentation, tooling, components, tokens, and contribution rules under one URL. Discoverable for designers and for AI.
Markdown source means models can index, retrieve, and reason about IDS the same way humans do.
Landed on the paved road inside AppFabric. Routing, observability, SSO, and CI/CD already in place.
