This Green Agent defines a deterministic and fully offline benchmark for evaluating agentic systems that retrieve paginate deduplicate and normalize Comtrade style international trade data. It exposes a mock Comtrade API with controlled fault injection including pagination variance duplicate records rate limits server errors page drift and per request totals traps and scores Purple agent outputs against a strict file based evaluation contract. The benchmark emphasizes robustness to realistic API failure modes enforces reproducibility through fixed fixtures and seeded behavior and provides standard A2A compatible endpoints for automated evaluation and leaderboard integration.
