Agent Setup and Tool Definition

Initialize the OpenAI Agents SDK and define a custom tool named 'legal_database_lookup' that simulates querying a legal database. This tool should accept a 'query' string and return a relevant legal document snippet or summary. Also, define another tool named 'policy_evaluation_tool' that takes a proposed action and a regulation, returning a 'PASS' or 'FAIL' along with a reason. Use Claude Opus 4.1 as your underlying LLM for the agent. Implement Hydra for managing the agent's configuration parameters.
