Overview

In 2026, I designed a visual feedback tool for coding agents in collaboration with Anthropic engineer Kyle Zhang. It has since been published on npm and used by other engineers at Anthropic & Salesforce.

My contribution to this project spread across design & development. I honed the interaction pattern and frontend architecture, while Kyle handled the MCP and backend.

As the design owner, I was responsible for leading strategy, user research, and product design to solve this challenge.

Problem & Solution

Glyph turns localhost into an interactable canvas so that design engineers can label UI changes for their AI coding agent.
