Introduction / Main Floor: Agent Eval Harness: A Practical Evaluation Framework for AI Agents and RAG Workflows

Agent Eval Harness is a practical benchmarking framework for systematically evaluating the performance of AI agents and RAG workflows in terms of task success rate, latency, cost, evidence quality, and governance compliance.

Background and Motivation

The AI agent ecosystem is evolving rapidly, but a key question emerges: how to objectively and reproducibly compare the effectiveness of different agents, prompts, tools, and retrieval strategies? The current market is flooded with various agent solutions claiming to be powerful, yet there is a lack of unified evaluation standards.

Teams need a simple way to:

  • Compare performance differences between different agent architectures
  • Evaluate the effectiveness of prompt engineering
  • Test the reliability of tool integration
  • Verify the accuracy of retrieval strategies
  • Ensure agents meet release standards

Agent Eval Harness was developed precisely to address these pain points.

Core Evaluation Dimensions

The framework designs evaluation metrics around six key dimensions:

Section 05

1. Task Success Rate

Measures the agent's ability to complete assigned tasks. This is the most core metric, directly reflecting the agent's practicality.

6

Section 06

2. Evidence or Citation Coverage

For RAG workflows, evaluates the completeness and accuracy of cited sources. Ensures the agent's answers are well-documented and not fabricated out of thin air.

7

Section 07

3. Latency Budget

Measures whether the agent's response time is within an acceptable range. For real-time interaction scenarios, latency is a key factor in user experience.

8

Section 08

4. Cost Budget

Tracks the actual cost of agent operation, helping teams make informed trade-offs between performance and cost.
