LAT.MD

lat.md is a spec that agents keep in sync with the code base that helps them understand big ideas and key business logic. It ensures that corner cases have proper high-level tests that matter and can speed up coding by saving agents from endless grepping. The spec uses plain Markdown, with Wiki links connecting concepts into a navigable graph.

PRETEXT

Pretext is a pure JavaScript/TypeScript library for fast and accurate multiline text measurement and layout. It circumvents costly DOM reflows by implementing its own text measurement logic using the browser's font engine. The library has two primary use cases: calculating a paragraph's height without DOM interaction for purposes like virtualization, and providing tools to manually lay out text lines for rendering to Canvas, SVG, or server-side.

JAI

AI agents are already causing data loss, from wiped home directories to deleted files, when granted ordinary machine access. jai provides an effortless, one-command solution for containing these agents on Linux, bridging the gap between full system access and complex virtualization. It works by giving your working directory full access while protecting your home directory with a copy-on-write overlay or complete isolation.
