• Shape UX of agentic workflows including spec-driven development, autonomous mode, parallel agents, and correctness verification.
• Iterate rapidly with paper sketches to high-fidelity prototypes, selecting appropriate tools for each challenge.
• Design cohesive experiences across desktop, terminal, browser, mobile, and open-source surfaces.
