        agent_name="human_evaluation_agent"
    )
    

Establishing Evaluation Policies

Creating structured evaluation policies ensures that human evaluators work within well-defined parameters. These policies should be integrated into the evaluation system's architecture to provide consistency. Utilizing a standardized schema helps in achieving uniformity across evaluations.

    const evaluationSchema = {
        type: "object",
        properties: {
            criteria: { type: "string" },
            weight: { type: "number" },
            threshold: { type: "number" }
        },
        required: ["criteria", "weight", "threshold"]
    };

    function evaluateAgentOutput(output, schema) {
        // Implementation of evaluation logic
    }
    

Ensuring Transparency and Accountability

Transparency in evaluation processes is achieved through clear documentation and visibility into decision-making workflows. Implementing agent orchestration patterns and integrating vector databases like Pinecone or Weaviate can enhance transparency by maintaining detailed records of evaluations and decisions.
