TimeEvo is a new method for time‑series agents that autonomously evolves its tool library based on failures observed during runtime. By clustering diagnosed failures into capability gaps, planning measurements, synthesizing evidence‑only tools, and admitting candidates through a paired gate, the system starts from an empty library and improves accuracy across ten QA tasks and three backbones. Experiments show that even a library built on a cheap model benefits stronger models when installed.

ReLiveGym is a diagnostic environment that evaluates long‑lived language‑model agents over weeks of chronologically replayed real‑world streams such as news, market data, and social media. The tasks vary in time sensitivity, reasoning depth, and recurrence, and the study tests eight base language models to see how model choice and harness design—especially action timing—affect performance. Continuous learning from hindsight feedback is also examined to address failure modes in these long‑term tasks.
