Curated skills beat self-generated ones for AI investment agents, new benchmark shows
FinSkillBench tests whether LLM agents can handle real investment work — point-in-time data retrieval, correct computational inputs, specialized methods, auditable outputs — across 3 domains, 12 subtasks, 2,603 episodes. Curated skill packages lifted mean scores from 0.366 to 0.528 across 9 models, while self-generated skills barely helped despite higher compute. The benchmark, tools, and trajectories are released.
