01 / Design layer for agent harnesses
2026 · Open source · local dogfood
Tell Proof
Agents write code. Tell proves the UI, then helps you ship design that looks intentional, not AI-default.

Problem
Coding agents compile. They still ship the same generated look: system fonts, violet accents, shadow on every card. The harness grades its own homework.
Approach
An independent critic beside Cursor. Playwright captures the rendered page. Fourteen detectors name genericness and drift. Direction becomes a reviewable patch. Proof runs in a disposable checkout.
Shipped
Next.js monorepo, MCP tools, Studio skill graph, and a captioned product demo. Open source. Local dogfood. No public production host claimed here.
