UnverifiedTools are the capability interfaces through which agents take action: read is used to analyze problems, edit or write is used to create and modify code, and bash is used to run tests.78% similarVerifiedHarness includes components such as system prompts, tool calling, file system, sandbox environment, memory system, task orchestration, hooks, feedback loops, and constraint mechanisms.78% similarUnverifiedA tiered toolset is a compromise: maintaining an extremely small core toolset to benefit from caching, while dynamically appending task-specific tool descriptions in the non-cached section of the system prompt through skill loading.74% similarVerifiedThe underlying mechanism of Tool Use is that developers pre-define the name, description, and parameter structure (Schema) of tools, and the model determines during inference when and which tool to call and outputs structured invocation instructions.74% similarUnverifiedA system that connects models, tools, state, and feedback is commonly referred to as a Harness, i.e., the operational framework of an agent.73% similar
