Production Tools

Not demos. Production systems built with Claude Code and used in real client work.

pretext -- text measurement playground

Canvas-based text layout without DOM reflow. Prepare once, relayout in ~0.0002ms.

ascii-art -- proportional ASCII animation engine

Brightness-mapped character rendering with Pretext measurement. Particle fields and torus modes.

Also: a multi-agent client management system that coordinates parallel Claude Code sessions across multiple active engagements, each with isolated context, project state, and tooling.
