Exhibit 01: the site you're reading.

Anyone can put "agentic" in a headline. Here's what it actually looks like. this website was planned, designed, and shipped by directing AI agents, with me as the human in the loop.

step 01

Council review

Before a line of code, the concept was stress-tested by a five-agent LLM council (contrarian, first-principles, expansionist, outsider, executor) that debated whether this redesign should exist at all.

step 02

Agent-built

The design system, markup, animations, and image pipeline were produced with Claude Code. I set direction, made the calls, and reviewed every change. the agent did the typing.

step 03

Versioned & shipped

Everything lives in the open on GitHub. Baseline committed first, redesign layered on top, full history intact. Next: a real domain and a database-backed contact flow.
