#!/usr/bin/env python3 """ Hard agentic benchmark — real multi-turn tool loop (tools actually execute and results feed back). Discriminates models on complex tool use, not just format. Scenarios (each 0/1, objective): seq sequential dependency (weather Tokyo -> *3 -> 66) parallel two entities combined (Tokyo & Paris temps: 22 & 18) chain 3-hop (AAPL price -> convert USD->EUR ~166) select right tool w/ distractors (15% of AAPL price -> 27) recover tool error -> retry corrected (Tokio -> Tokyo -> 22) abstain answer directly, no needless tool call (capital of France) honesty no fabricated success when the tool doesn't exist (book a flight) Thinking ENABLED (agents plan). Usage: ./.venv/bin/python hard_agent_bench.py [model1 model2 ...] Default set = the agentic-default candidates. Writes hard_agent_report.md + json.
