LLM Evaluation Tau-bench Tool-Agent Benchmarks

## TL;DR

Tau-bench evaluates tool agents in interactive user conversations where success depends on both tool calls and dialogue state.

## Core Explanation

Many tool-use evaluations are single-turn function-call tests. Tau-bench is useful for agent readiness because it includes a user interaction loop and domain tools, so failures can come from policy interpretation, slot filling, tool arguments, or conversation recovery.

Agents should treat tau-bench scores as environment-specific evidence and preserve domain version, task ID, user simulator, tool schema, prompts, seeds, and grader configuration when comparing runs.
