# AgentLens Argues Code-Agent Benchmarks Should Grade the Whole Trajectory, Not a Pass/Fail Bit

The production-assessed benchmark reviews the full run of interactive coding agents, targeting the gap between "task passed" and how the agent actually behaved.

A new benchmark paper, AgentLens, makes a pointed critique of how the field evaluates code agents. Most current benchmarks collapse an entire agent run into a single bit, whether the task passed, while the engineers who actually use these a…
