NVIDIA has open-sourced SkillEvaluator, an Apache 2.0 framework for checking whether AI agent skills are safe, distinct, and effective. It combines static validation, similarity analysis, and sandboxed agent runs so developers can evaluate a skill before adding it to a catalog or shipping it to users.

Agent skills are folders containing Markdown instructions, metadata, scripts, and reference files that extend coding agents such as Claude Code and Codex. As these packages multiply, maintainers need automated checks for insecure code, exposed credentials, duplicated guidance, and instructions that fail to improve task results. SkillEvaluator follows the community Agent Skills specification and forms part of NVIDIA’s broader Verified Skills pipeline.
