UnverifiedThe session log is Harness's "source of truth," and system prompts, model outputs, tool calls and results, sub-agent scheduling, and context injection can all be replayed along the event stream70% similarUnverifiedOperational traces include the inputs and outputs of complete sessions, the model or tool selected and its output at each node, tool calls, file read/write commands, and test logs.70% similarUnverifiedDuring multi-turn tool calls, each tool execution result is appended to the conversation history as a new tool_result message, and the model reads the outputs of previous steps from the conversation context rather than retaining intermediate values in internal memory.68% similarUnverifiedBuilding a complete logging system is the most fundamental and important method for analyzing AI agent behavior, and should record task descriptions, each operation, timestamps, generated code, and error messages.68% similarUnverifiedAfter the interview ends, the system automatically transcribes the recording and inputs the complete conversation record into the large model, generating a structured evaluation report across dimensions such as expressive logic, professional skills match, and communication ability via a Prompt template.68% similar
