ContextAI

Universal context engineering CLI for AI coding agents. Define your project's conventions, stack, and architecture in a single context.config.ts file, then generate AI-readable context files for multiple tools from that single source of truth.

How It Works

Run init

Interactive wizard detects your framework and creates context.config.ts with sensible defaults.

Describe your project

Add your stack, conventions, architecture, and rules you want every AI agent to follow.

Generate

Run generate once — or use watch mode to keep all output files in sync automatically.

Stay in sync

Validate and diff commands check that all AI context files reflect your latest config.
