Tech Demos
Weekday bookmark demos
Small interactive apps built from X bookmarks — one self-contained Vite app per demo, all deployed from a single monorepo and grouped by theme.
Design & AI UI
How agents ship on-brand, researched UI — taste files, design systems, and reference-driven workflows.
-
Vercel design.md /vercel-design-md/
A/B playground rendering the same product brief without and with Vercel’s design.md — why one taste file changes AI-generated UI.
-
Astra + Mobbin research /astra-design-research/
Research-first workflow: Astra agents pull Mobbin references before generating UI so outputs match real product patterns, not generic slop.
Agent UI & harnesses
Generative UI and the decisions that turn a chat model into a worker you can leave unattended.
-
CopilotKit AG-UI /copilotkit-ag-ui/
Generative UI playground for the AG-UI protocol: an agent streams typed events that render as real React components.
-
Six decisions harness /agent-harness/
Flip six harness cards — loop/stop, tools, context, verification, permissions, observability — and watch a toy agent run change.
Software factories
Cost equations and adoption maturity — from crawl→walk→run ladders to running a factory efficiently at scale.
-
Uber cost equation /uber-software-factory/
Interactive playground for the agent cost equation from Uber’s “Running a Software Factory Efficiently at Uber Scale.”
-
Warp crawl→walk→run /software-factory-crawl-walk-run/
Adoption ladder: pick team maturity and a work item, then see which SDLC steps are factory agent, point automation, or still human.
