UnverifiedA coding agent's harness includes prompt templates, tool-calling interfaces, context management, error recovery mechanisms, and feedback loops; it determines how the model perceives the task, performs actions, and learns from results.78% similarVerifiedFunction calling (tool calling) refers to the ability of a large language model to proactively request the invocation of external functions or APIs during the generation of a response.77% similarVerifiedThe tool-calling (Function Calling) mechanism allows the model to invoke external tools during reasoning, such as file read/write operations, terminal commands, and search APIs.77% similarUnverifiedThe tool-calling interface is the standard mechanism for large language models to interact with external systems: the model outputs structured function names and parameters during generation, which the runtime environment executes and returns the results.77% similarUnverifiedCommon implementations of structured output include providing a function calling interface, constrained decoding, or post-processing parsing plus validation.75% similar
