WebPerf Snippets started as a collection of snippets to paste into the DevTools console. With version 2.0, they are also built for AI agents to run webperf-snippets.net 🧵 #WebPerf #AI

That shared contract (status, value, rating, issues) is why this is a major version: if you read the output from code, some fields have changed. 56 snippets, 7 of them new: compression, Early Hints, Speculation Rules, third-party impact by domain, and more.

For agents: • A "Copy prompt" button next to the snippets, so an agent runs them with the CLI and reports back • Agent Skills for Claude Code, Gemini CLI and other agents • A Markdown version of every page, llms.txt and WebMCP tools #WebMCP #SKILLS

The CLI reaches 1.0: audit, loading and interaction workflows, CrUX data, and a GitHub Action with LCP and CLS budgets. `npx webperf-snippets example.com` webperf-snippets.net/CLI #CLI

Also new: 17 interactive demos, the browser support of each snippet, and a DevTools extension in beta. webperf-snippets.net/extension
