Global Tax & Legal Compliance Advisor Agent
This challenge focuses on developing a sophisticated legal and tax compliance advisor using the OpenAI Agents SDK. The agent will interpret complex regulatory texts, answer specific compliance queries for various jurisdictions, and justify its advice by citing relevant statutes. A core component will be the integration with a simulated MCP knowledge base, powered by Pinecone, to provide the agent with a vast, searchable repository of legal and tax documents. The challenge emphasizes advanced tool use, multi-LLM verification (using GPT-4o for primary analysis and Claude Opus 4.1 for cross-validation), and rigorous evaluation of accuracy and transparency.

How submissions are scored
These dimensions define what the evaluator checks, how much each dimension matters, and which criteria separate a passable run from a strong one.
CorrectComplianceDecision
Agent's 'is_compliant' decision matches the expected outcome for known scenarios.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
CitationCount
Advice includes at least 2 relevant citations for complex queries.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
AdviceCompletenessScore
Expert-rated score for the completeness of the advice (1-5). • target: 4 • range: 1-5
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
ReasoningClarity
Expert-rated score for how clearly the agent justifies its advice (1-5). • target: 4 • range: 1-5
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
Master the OpenAI Agents SDK's function calling and tool definition mechanisms to create robust interactions with external systems.
Design a simulated MCP knowledge base using Pinecone vector database to store and retrieve legal and tax documents, accessible via agent tools.
Develop custom Python tools for the agent to query, extract, and summarize relevant information from the Pinecone-backed MCP.
Implement a multi-LLM strategy where GPT-4o provides primary legal analysis and Claude Opus 4.1 acts as a secondary, independent verifier for critical compliance points.
Craft effective prompts for GPT-4o to ensure accurate interpretation of specific legal clauses and generation of precise compliance advice, citing relevant regulations.
Build an evaluation harness with Testaify to systematically test the agent's responses against a corpus of legal scenarios, measuring accuracy, completeness, and adherence to legal principles.
Implement mechanisms for the agent to explicitly state its reasoning and cite specific regulations to justify its compliance advice.
