The paper introduces TURTLE, an Unsupervised Environment Design framework that evolves tool‑use tasks for AI assistants by using a proposer, solver, and feedback generator powered by large language models. TURTLE automatically generates self‑tuning, long‑horizon benchmarks that increase task difficulty, diversity, and failure modes across multiple applications. Experiments on AppWorld, τ‑Bench, and AutomationBench demonstrate significant gains in hard task percentages and broader reasoning challenges.

Neuroscience data are fragmented across labs and formats, making reuse labor‑intensive. This study benchmarks coding agents on eight recent mouse neural recording papers, asking them to reformat data for a common decoder task. While agents handle many subtasks, they rarely produce fully error‑free solutions; the authors pair outcome metrics with a process rubric to evaluate errors and propose agent‑assisted data‑sharing practices.

arXiv:2604. 00594v2 Announce Type: replace Abstract: As the focus in LLM-based coding shifts from static single-step code generation to multi-step agentic interaction with tools and environments, understanding which tasks will challenge agents and why becomes increasingly difficult.
