The authors developed Harness Primitives, reusable mechanisms that govern parts of an agent's execution, such as gathering context, invoking tools, preserving state and checking results.
Reusable harness components let agents adapt workflows to each task
STITCH selects prebuilt control mechanisms from task information, then deterministically compiles them into an executable agent harness.

Thread:Agent Harness Optimization
Kuang and colleagues argue that a single agent harness is poorly suited to heterogeneous tasks because mechanisms such as verification, context management and termination logic can help in one setting but distract or slow an agent in another.
