Overview
WebPerf Snippets is a set of tested JavaScript code snippets for measuring and debugging web performance. These snippets can be run by AI agents or manually in DevTools. They return structured data, enabling AI agents to better interpret performance metrics. By using these snippets, AI agents can execute the same code in terminals, CLI, DevTools extensions, or Agent Skills, returning objects that adhere to a unified contract.
