Modular Capability Compositions — Agent Architectures

OpenHands is an autonomous agent framework designed for software engineering workflows. It provides a modular platform for orchestrating AI agents that reason, plan, and execute tasks within isolated, containerized development environments. By integrating with standard version control and development tools, the system enables agents to autonomously navigate codebases, implement features, and resolve issues through iterative reasoning and tool execution. The platform distinguishes itself through a model-agnostic orchestrator that connects diverse language models to a unified tool registry. It supports complex, multi-agent collaboration via hierarchical task delegation, allowing parent agents to spawn and manage independent sub-agents for parallelized workflows. Security is managed through configurable action approval policies and real-time risk evaluation, ensuring that autonomous operations remain within defined safety boundaries. The system covers a broad capability surface including persistent conversation state management, automated code review, and web research automation. It features an event-driven architecture that serializes interactions into immutable logs, facilitating observability and time-travel debugging. Developers can extend agent functionality through custom skill definitions, plugin packages, and integration with external services via standardized protocols. The project provides a command-line interface for managing agent sessions, remote server deployments, and containerized workspace lifecycles. It is designed for extensibility, allowing users to configure agent behavior through structured objects, markdown-based definitions, and environment-specific settings.
