The Harness layered structure improves the decomposability and maintainability of tasks, but it also makes the runtime process harder to observe: a single user request triggers multiple model calls and tool calls, and context flow across agents is hidden inside the code.

UnverifiedData flywheel mechanism: the harness lowers the task barrier so that more users use the Agent to handle harder coding tasks, and the resulting interaction data is shared with model labs for training; once the model's capabilities improve and it natively masters these skills, the harness can remove the corresponding auxiliary logic.79% similarUnverifiedHarness-type projects usually refer to the orchestration layer between the underlying model and the upper-layer application, responsible for model loading, inference scheduling, tool calling, context assembly, plugin registration, and other tasks.78% similarUnverifiedThe harness layer decouples decision-making from execution, allowing developers to insert security logic such as permission verification, behavioral auditing, and rate limiting without modifying the underlying model.77% similarVerifiedHarness is not a large model, but a workbench (orchestration layer/AI Agent framework) wrapped around the model, responsible for the interface, session recording/replay, and tool invocation.76% similarUnverifiedThe advantage of Harness architecture agents lies in handling complex tasks, which often involve a large number of file operations and require dedicated file backend support75% similar
