Addy Osmani's skills help an AI agent with the work around shipping web software: browser testing through Chrome DevTools to inspect the DOM, console errors, network requests and performance, root-cause debugging when tests or builds fail, building accessible and responsive frontend UIs, setting up CI/CD pipelines with quality gates, and running web quality audits covering performance, accessibility and SEO. His most popular skill, Doubt Driven Development, has the agent put non-trivial decisions through a fresh-context adversarial review before they stand.
