The Case Against Skills

Use them intentionally, or they could make your AI worse

The Case Against Skills

TL;DR

  • Elaborate custom skill libraries, popularized on platforms like X, may not be improving AI performance and could be making it worse.
  • Frontier AI models are often capable of reasoning independently, rendering many skills unnecessary and potentially causing confusion.
  • Skills can inflate costs and introduce errors when they conflict with a model's inherent training and capabilities.
  • Useful skills are typically those that provide specialized guidance, access to private company data, or custom workflow instructions.
  • A benchmark test showed that a majority of software-engineering skills had no impact on performance, and some decreased it.
  • The utility of skills has a shelf life, especially those designed to patch a model's weaknesses, as new models absorb these capabilities.
  • An audit of AI skills is recommended, focusing on keeping those that provide private context, custom tool access, or specific workflows, and retiring those that don't demonstrably improve results.
