Can Agents Design Libraries for Agents?
LibraryDesignBench finds coding agents can match human library designs but downstream agents still underuse them.
LibraryDesignBench measures whether coding agents can design reusable libraries for other agents. An agent implements a library from a capability specification, then three user agents from different model families write programs against it. Across 242 expert-validated problems and 15 tasks in four languages, designers reproduce human production abstractions on 11 tasks, but downstream agents still reimplement provided capabilities because libraries are rigid or hard to use. More prescriptive, agent-first guidance and subagent testing improve downstream scores.

- Agent designers match human abstractions on 11 of 15 tasks
- Downstream agents underuse libraries and reimplement existing features
- Prescriptive guidance and subagent tests yield simpler programs

Agents increasingly build on code written by other agents, and they reimplement rather than reuse, growing the codebases later agents must work in.
