TLDR: The Agent GPA (Goal-Plan-Action) framework is a new evaluation paradigm for AI agents, assessing their performance across goal setting, planning, and action execution. It introduces five core metrics: Goal Fulfillment, Logical Consistency, Execution Efficiency, Plan Quality, and Plan Adherence, complemented by Tool Selection and Tool Calling. Utilizing LLM judges, the framework offers automated, scalable evaluation that strongly agrees with human judgments, systematically detects a wide range of agent failures, and localizes errors for targeted improvement. Experimental results on TRAIL/GAIA and Snowflake Intelligence datasets validate its effectiveness in providing actionable insights into agent behavior.
As artificial intelligence systems become more sophisticated, moving beyond simple chatbots to autonomous agents that can plan, use tools, and collaborate, the need for robust evaluation methods has grown significantly. Traditional evaluation often focuses only on the final outcome or relies heavily on time-consuming human annotations, providing little insight into why an agent might fail or how to improve it.
A new research paper introduces the Agent GPA (Goal-Plan-Action) framework, a novel approach designed to systematically evaluate AI agents based on their fundamental operational cycle: setting goals, devising plans, and executing actions. This framework aims to provide a more comprehensive understanding of agent performance by analyzing failures at each stage of this cycle.
The Agent GPA framework is built around five core evaluation metrics:
Goal Fulfillment
This metric checks if the agent’s final outcomes successfully match its stated objectives. It’s about whether the agent actually achieved what it set out to do.
Logical Consistency
Logical Consistency ensures that an agent’s actions are coherent and consistent with its previous steps and context. It also verifies adherence to system instructions and proper error recovery.
Execution Efficiency
This metric assesses whether the agent performs its tasks in the most efficient way possible to reach its goal, looking for redundancies, unnecessary tool calls, or wasted resources.
Plan Quality
Plan Quality evaluates if an agent’s plans are well-aligned with its goals. An optimal plan breaks down the goal into minimal, actionable subtasks, selects appropriate tools, and balances detail. It also assesses the quality of any replanning in response to new information or errors.

Plan Adherence
Plan Adherence checks if an agent’s actions faithfully follow its stated plan. This is crucial for understanding if the agent can stick to its strategy, regardless of the plan’s initial quality.
In addition to these core metrics, the framework also includes specialized judges for Tool Selection (evaluating if the most appropriate tool was chosen for a subtask) and Tool Calling (examining the correctness of how a tool was invoked and its outputs interpreted).
A key innovation of the Agent GPA framework is its use of LLM (Large Language Model) judges for automated evaluation. These LLM judges are designed to exhibit strong agreement with human annotations, covering a high percentage of errors and localizing them to specific parts of the agent’s process. This automation offers significant scalability benefits compared to manual evaluation.
The framework was rigorously tested on two benchmark datasets: the public TRAIL/GAIA dataset and an internal dataset from a production-grade data agent called Snowflake Intelligence. The experimental results demonstrated that the Agent GPA framework provides a systematic way to detect and categorize a broad range of agent failures. It successfully identified nearly all errors in the TRAIL/GAIA dataset, with LLM judges showing strong alignment with human judgments, especially for medium and high-impact errors. Crucially, the framework also proved effective at localizing errors, pinpointing the exact source of a problem to enable targeted debugging and improvement of agent performance. The consistency of these LLM judges across repeated evaluations further strengthens their reliability as automated evaluators.
The Agent GPA framework represents a significant step towards more rigorous, scalable, and interpretable evaluation of AI agents. By aligning evaluation with how agents naturally operate—through goals, plans, and actions—it helps in building more capable and trustworthy AI systems.
