"""Tool-calling benchmark: mock tools, agentic tasks, agent loop, scoring.
Runs a model through a suite of agentic tasks requiring one or more tool calls.
Each task is scored on: correct tool selection, argument quality (via deterministic
executor results), forbidden-tool avoidance, final-answer content, and iteration
budget. Designed to exercise full agent-harness behavior: parallel tool calls,
multi-step plans, tool-result feedback, and termination on final answer.
