Everything your agents need

A complete system for building production-ready AI agents — from first gene to published marketplace listing.

Skills

Define precise, reusable capabilities your agents invoke on demand — from web search to data analysis.

Tools

Connect agents to any API, database, or external service with structured, versioned tool definitions.

Souls

Encode personality, tone, and behavioral constraints that make each agent distinctly yours.

Marketplace

Buy, sell, and license genes from a growing community of AI builders. Monetize your work.

Version Control

Every gene is a markdown file. Git-native versioning, diff-friendly, and endlessly portable.

Playground

Compose genes live and chat with your configured agent in real-time before you ship.

Why AgentDNA
