A study benchmarked over 300 NVIDIA-verified skills to evaluate their real-world impact on agent performance. Results showed that using these skills improved correctness by 41 points, effectiveness by 39, and efficiency by 35. The SkillEvaluator tool is now open source for users to test their own skills.

NVIDIA released a large-scale benchmark comparing AI agents with and without skills, showing significant improvements in correctness, effectiveness, and efficiency, and open-sourced the testing tool SkillEvaluator.
On August 19, 2026, NVIDIA's official AI account announced that its team had benchmarked over 300 NVIDIA-verified skills to assess their real-world impact on AI agents. The test design emphasized 'same task, same model, same setup,' with the only variable being whether the agent possessed the skill. This controlled approach aimed to isolate the effect of the skill itself.
According to NVIDIA's data, across all benchmarks, skills improved agent correctness by 41 percentage points, effectiveness by 39, and efficiency by 35. These figures vividly demonstrate the significant impact of skills. However, specific task types, skill categories, and detailed benchmark methodology have not yet been disclosed, so the generalizability of these improvements remains to be verified.
NVIDIA also announced that SkillEvaluator is now open source, allowing developers to test their skills before release. This initiative aims to help the community validate skill quality, thereby enhancing the overall ecosystem's reliability. NVIDIA also published a technical deep-dive blog detailing SkillEvaluator's evaluation methodology, providing a reference for developers seeking deeper understanding.
Following the announcement, community members commented asking if they could get help testing their personal skills, such as Rooke Poole's PARS skill. This indicates a real demand for skill evaluation tools. However, the publicly available information is limited to NVIDIA's official statements, and no independent third-party verification of the data has been conducted. Additionally, the specific task scope, skill types, and definition of evaluation metrics remain unclear, so whether these improvements generalize to all scenarios is unknown.
This report is based on information from NVIDIA's official social media, which is a first-party claim and has not been independently verified. For specific test details and evaluation methods, refer to their technical blog, though this report does not directly cite that blog.
NVIDIA's benchmark preliminarily suggests that skills can significantly enhance AI agent performance, but the actual effect varies by task. Developers should use tools like SkillEvaluator to validate their skills.
