Overview

While prototyping with AI tools like Claude Code, I ran into a recurring issue: outputs were inconsistent because there was no structured reference of the Jenkins design system to guide them.

So I built one.

I designed and shipped a centralized design system reference, optimized for both humans and AI tools, and published it to the team’s internal workbench.

Impact:

  • Improved consistency in AI-generated prototypes

  • Reduced time spent correcting design outputs

  • Created shared infrastructure for the entire design team

The problem

AI-assisted prototyping broke down without a reliable system reference.

Designers were facing:

  • Inconsistent outputs (wrong components, spacing, styles)

  • Time lost manually fixing generated designs

  • Knowledge scattered across the product and individual teams

The missing piece wasn’t tooling, it was structured input.

My role

I drove this end-to-end:

  • Identified the gap through hands-on AI prototyping

  • Audited and structured the Jenkins design system

  • Built and published the reference using Claude Code

  • Made it accessible as a shared team resource

This was a self-initiated project focused on team enablement, not just individual productivity.

The solution

I created a single, structured source of truth designed for AI-assisted workflows.

1. Consolidated system reference

Tokens, components, and usage guidelines in one place
→ Eliminates guesswork and fragmented knowledge

2. Structured for AI consumption

Organized to be easily used in prompts and generation workflows
→ Improves accuracy and consistency of outputs

3. Accessible team infrastructure

Published to the internal workbench
→ Enables adoption across the entire design team

How I approached it

This wasn’t just documentation, it was about making the system usable in a new context (AI workflows).

  • Audited tokens (colors, typography, spacing) and component usage

  • Structured content in layers: tokens → components → guidelines

  • Built directly in code using Claude Code

  • Iterated until outputs matched real product behavior

Outcomes

New team capability

  • Enabled designers to prototype faster and more reliably with AI tools

Consistency at scale

  • Reduced visual drift between AI-generated designs and the real product

Leverage beyond individual work

  • Turned a personal workaround into shared infrastructure

What I’d do next

Evolve this into a maintained system:

  • Add interactive component previews

  • Validate structure with the broader team

  • Integrate with existing design system workflows and updates

Key takeaway

AI doesn’t replace design systems, it depends on them.

This project shows how I think beyond screens, building the infrastructure that makes new ways of working possible.
