Beyond Accuracy: The 73+ Dimensions of AI Agent Quality

“Is My Agent Good?” Is the Wrong Question

When a developer asks, “Is my AI agent good?” they’re often looking for a single score, like an accuracy percentage. This is a dangerous oversimplification. An AI agent is a complex system, and its quality can’t be boiled down to one number.

An agent isn’t just “good” or “bad.” It can be factually accurate but dangerously non‑compliant. It can be helpful but horribly inefficient. It can be safe but provide a terrible user experience.

To truly understand your agent’s performance, you need to evaluate it across multiple dimensions simultaneously. At Noveum.ai, we’ve identified over 73 distinct scorers, grouped into several key categories.

The Core Dimensions of Agent Quality

Here are some of the most critical dimensions you should be tracking:

1. Correctness Dimensions

• Factual Accuracy – Does the agent provide information that is verifiably true?
• Instruction Following – Does the agent adhere to the explicit instructions in its system prompt?
• Context Adherence – Does the agent use only the information provided in the given context, especially in Retrieval‑Augmented Generation (RAG) systems?

2. Safety and Security Dimensions

• Toxicity Detection – Does the agent avoid generating hateful, offensive, or inappropriate language?
• PII Protection – Does it refuse to process or reveal personally identifiable information?
• Prompt Injection Resistance – Can the agent be tricked into violating its instructions by a malicious user prompt?

3. Efficiency Dimensions

• Tool Call Efficiency – Is the agent making redundant or unnecessary API calls?
• Token Efficiency – Is it being overly verbose, driving up LLM costs?
• Reasoning Efficiency – Does it get stuck in loops or take a convoluted path to a simple answer?

4. User Experience Dimensions

• Conversation Coherence – Does the agent maintain a logical and easy‑to‑follow conversation flow?
• Relevance – Does it stay on topic and provide answers that are relevant to the user’s query?
• Helpfulness – Does it actually solve the user’s underlying problem?

5. Compliance Dimensions

• Regulatory Compliance – Does the agent’s behavior align with legal frameworks like GDPR, HIPAA, or CCPA?
• Company Policy Adherence – Does it follow your internal guidelines for brand voice, tone, and values?

Why Multi‑Dimensional Evaluation Matters

Most teams only look at one or two of these categories, typically correctness. This creates massive blind spots. You might have an agent that is 99 % factually accurate but leaks PII in 5 % of conversations. Without a multi‑dimensional evaluation framework, you’d never know until it’s too late.

The only way to de‑risk your AI agent for production is to have a comprehensive suite of scorers that evaluates its performance from every possible angle. Stop chasing a single accuracy score and start building a holistic view of your agent’s quality.
