The authors introduce EvoWeb, a benchmark designed to evaluate coding agents under a common development pattern: repeatedly extending an existing web application rather than implementing one fixed specification.

EvoWeb organizes real-world product features into functional dependency graphs, which represent how later requests rely on earlier functionality.
