Teaching a design system to work with AI
Made Slingshot's design system AI-ready — 180+ components and 800+ tokens mapped between Figma and code, with governance that keeps design decisions human.
Context
Slingshot is Infragistics’ enterprise work-management platform, built on a large design system in a proprietary UI framework and Figma. As the team adopted AI coding tools, a gap appeared: the system meant to keep everything consistent couldn’t be read reliably — not by the AI, not by new people. I led the work to fix that: make it legible to machines, keep the judgment with the people.
My role
I owned the system’s AI-readiness end to end — token architecture, the design↔code mapping, the shared vocabulary, and the rules for what an AI may and may not do — working alongside a product owner, for the fellow designers who used the system daily.
Research & insight
I watched where things broke:
- Design and code had drifted apart. One button, hundreds of Figma variants, no authoritative map to its code props — so everyone guessed.
- Tokens existed; the rules didn’t. No guidance on which tier to use, so raw values crept in.
- The vocabulary had drifted. One idea, many names (“rest” vs. “default”).
- Context lived in people’s heads — every new collaborator started from zero.
The insight: an AI isn’t sloppy because it’s dumb, but because the system never told it the truth. Give it the same clear contract you’d give a new teammate, and it behaves like one.
What I did
Gave the tokens a backbone. ~800 tokens in a four-tier chain, one rule per tier, with light/dark as a mode on the semantic layer — a right answer for every value.
Set one vocabulary. Kebab-case, one size scale, one name per concept across Figma and code.
Wrote the context down. The rules live as version-controlled docs a tool loads fresh each session — change a rule, the next build follows it.
What stayed human
The point wasn’t to let AI build the system. It was to keep human judgment in charge:
- Plan before build — the AI proposes; I approve or reject before a line is written.
- Never invent — if something’s missing, it stops and asks instead of faking it.
- The real calls stayed ours — new component vs. compose, which pattern replaces which, how the tiers are shaped.
Outcome
The system became something an AI could build with and a person could trust — agents now produce on-token, on-brand code, so designers direct the work instead of fixing it. And because every change still passes a human approval gate, speed went up without giving up control.
That’s the model I believe in: not automation that replaces the designer, but structure that lets them move faster while owning every decision.
