agentic evaluation
When you evaluate an AI agent, you don't just test what it knows. You test how well it acts in a messy, changing environment: gathering information, using tools, keeping track of long goals, and recovering from mistakes. Agentic evaluation builds realistic tasks and careful scoring to see whether an agent can truly get things done, not just answer questions.
Across these studies, a clear pattern emerges. Agents often handle individual steps well but collapse over longer horizons. They fail to monitor important state, coordinate across devices, or correct accumulated errors. Worse, common evaluation methods can flatter them, hiding inefficiency, missing context, or scoring attacks wrongly. Better benchmarks and diagnostics are needed before claims about real-world readiness hold up.
