Atomic Agents
Atomic Agents is a lightweight Python framework for building modular Agentic AI pipelines and applications using Pydantic and Instructor schema validation.
Atomic Agents is a framework for constructing AI agents as modular, reusable components similar to building with blocks. It helps developers create predictable AI pipelines by defining strict input and output schemas for each agent and tool. The system operates on standard software engineering principles, allowing developers to manage logic and control flow entirely in Python. It supports dynamic context injection through providers that can be registered to agents at runtime. It is designed for developers who require fine-tuned control over system prompts and tool integrations. The framework natively integrates with Instructor and Pydantic for validation and provides CLI tools for project scaffolding and management.
