1. Background and Challenges

A large-scale design system update was needed, but resources were limited because only one person was responsible for each platform.
Even for a simple task such as revising the avatar component, execution took far more time than judgment: reviewing the current state across three platforms (Web, iOS, and Android), researching, working in Figma, documenting, creating Jira tickets, and sharing updates in Slack.

2. Building an Automated Workflow (/component-improve Skill)

Step 1 (Reviewing the current state): Read GitHub repositories in parallel to identify inconsistencies across platforms
Step 2 (Research): Use sub-agents to research public design system materials in parallel and extract insights
Step 3 (Figma work): Automate token and layer work on a branch with Figma MCP
Step 4 (Documentation updates): Automatically generate update notes, examples, handoff documentation, and policies and formulas
Steps 5–6 (Tickets and sharing): Use Atlassian MCP to create Jira tickets, then Slack MCP to share updates in channels and deliver reports

3. Dividing Responsibilities Between AI and People

AI’s role: Repetitive execution, rule-based work, and numerical and formula calculations
People’s role: Deciding update specifications (judgment), conducting visual reviews, and providing safeguards (approval before each step proceeds)

4. Results and Impact

The time required to revise one component was dramatically reduced from about five days to one day.
Checking source-code consistency reduced the demand on developers and enabled designers to contribute directly to code-based QA.
Context and decision records accumulated into a sustainable team asset.

XPLORED View

This case shows that the value of AI in design system operations lies less in replacing judgment than in connecting repetitive execution across research, design, documentation, tickets, and sharing into a single, approval-ready flow.

Good to read when

When a small team is managing a design system across multiple platforms
When you want to structure a recurring component-improvement process as an agent skill

Takeaways

Defining both the scope of automation and the points for human approval helps maintain speed and quality at the same time
Connecting code-consistency checks and decision records turns a one-off efficiency gain into a sustainable operational asset for the team
