AgentKogei

Durable, Project level design direction for AI coding agents through one Design Contract.

AgentKogei publishes complete Design Systems for AI coding agents. Choose a direction from the public Design Systems collection, install its Design Contract in your Project, and give every agent the same visual and behavioral guidance.

Design Systems

Design System	Direction
Foundation	Neutral, crisp, and highly legible B2B SaaS
Editorial	Warm, spacious, and content forward SaaS
Mono	Monochrome, high contrast interfaces for media and creative tooling
Command	Dark first, dense interfaces for developer and operations products

Every Published Design System and all AgentKogei source code are available under the MIT License. Their Design Contracts and Design System Evaluation evidence are committed in packages/design-systems/releases.

What is a Design Contract?

A Design Contract is a single, self contained DESIGN.md file at a Project root. It gives AI coding agents complete direction for tokens, layout, components, interaction states, motion, accessibility, and implementation examples.

File	Purpose
AGENTS.md	Tells coding agents how to work in the Project
DESIGN.md	Tells coding agents how the Project should look and behave

An Installed Design System remains usable without AgentKogei or network access. Installation guides future agent work and does not automatically redesign an existing interface.

Install a Design System

Run the CLI from a Project root:

npx agentkogei@latest add foundation

Equivalent pnpm dlx, yarn dlx, and bunx commands are also supported. A bare identity selects the current Design System Release. An exact selector such as foundation@1.1.0 selects that immutable release.

Before changing the Project, the CLI previews the selected release and the files it will write. Installation writes one root DESIGN.md and one marked reference in AGENTS.md. It never executes supplied code, installs dependencies, creates hidden state, or replaces an existing Design Contract without explicit consent.

Every Design Contract is retrieved anonymously from the public AgentKogei Design Systems. The application has no authentication, billing, database, or persistent application state.

Development

Install dependencies and start the web application:

bun install
bun run dev

Open http://localhost:3001.

Run the complete technical verification:

bun install --frozen-lockfile
bun run launch:verify

This checks formatting, types, production builds, the distributable CLI, and the full black box suite.

Deployment

The public Design Systems application is configured for Vercel through vercel.json. Pull requests receive preview deployments, and merging main triggers the production deployment through the connected Vercel Git integration.

The CLI commands remain available for local deployment diagnostics and exceptional manual operation:

bun run deploy:setup
bun run deploy:check
bun run deploy
bun run deploy:prod
