expect-cli: The Validate Step My Agent Loop Was Missing

CLI that reads your git diff, generates a test plan via AI, and executes it in a real browser with Playwright. Extracts cookies from your local browser for authenticated sessions.

BlogBrowser Tools for AI Agents

Browser Tools for AI Agents Part 1: Playwright, Puppeteer, and Why Your Agent Picked Playwright

The low-level browser automation tools. Why Playwright won the agent war, what dev-browser does differently, and when you need Patchright or Scrapling for the dodgy stuff.

Browser Tools for AI Agents Part 2: The Framework Wars (browser-use, Stagehand, Skyvern)

Agent browser frameworks compared. DOM-first vs vision-first, the caching trick that changes economics, and why expect is a completely different thing.
