OpenAgentsControlAgent44/100 via “registry-driven agent composition with hierarchical delegation”
AI agent framework for plan-first development workflows with approval-based execution. Multi-language support (TypeScript, Python, Go, Rust) with automatic testing, code review, and validation built for OpenCode
Unique: Uses a declarative registry.json as the single source of truth for agent definitions, enabling agents to be discovered and composed dynamically at runtime rather than through hardcoded imports. The hierarchical delegation pattern (primary agents → subagents) is explicitly modeled in the registry with typed component categories (Agents, Subagents, Contexts, Commands), allowing the framework to enforce composition rules and validate agent relationships during installation.
vs others: More maintainable than agent frameworks that require code changes to add new agents, and more flexible than monolithic agent designs because agents can be versioned, swapped, and composed independently through registry metadata rather than tight coupling.
