Source of Truth

Keep one canonical `.ulis/` tree and remove config drift across tool-specific formats.

Build + Install

Generate into `/generated/` and deploy straight into each tool's expected directory layout.

Safe Validation

Parse with schemas, catch collisions and broken references early, and fail fast before writing invalid configs.

$bun add -g @nejcm/ulis

$ulis init

$ulis install --yes

Why ulis

Every AI coding tool has different file formats and feature naming. ulis gives you a neutral model in .ulis/ and compiles that into native outputs for each target platform.
