Agent Core
Owns ReAct, planning, model and context orchestration, tool selection and Memory access.
ARCHITECTURE
One core, one harness, many agents.
Hypha separates reusable runtime authority from product-specific behavior. A DomainPack compiles into the same governed execution system without copying the framework.
Production Harness
Owns the canonical FSM, bounded execution, policy, evidence, continuation, recovery and replay.
DomainPack
Declares tasks, workflows, prompts, capabilities, policy, evaluation and output contracts.
Cache & Reuse Plane
Accelerates validated work across reasoning, tools, Memory, execution and inference without becoming authority.
