Summary

Codex's data analysis capabilities, although strong, face challenges when analytical conventions are not explicitly stated, leading to inconsistent results with business rules and user expectations. The study investigates if reusable Skills, which encapsulate task rules, field definitions, and lessons from previous failures, can enhance Codex’s accuracy on similar unseen tasks. Using the open-source DataCOPE framework, experiments were conducted to generate Skills from task trajectories, yielding improvements in Codex’s performance by making implicit analytical conventions explicit, clarifying task objectives, and converting complex workflows into executable procedures. Skills also help Codex avoid recurring errors by converting failure experiences into a checklist. However, Skills have limitations, including the potential to reinforce incorrect interpretations, applicability only to specific task types, and the inability to replace human validation. The study suggests structuring Skills as fixed workflows with supporting scripts to maximize their effectiveness, emphasizing that human oversight remains crucial for problem definition and validation, while Skills can enhance Codex’s reliability as a data analysis assistant.
