A curated inventory of 232 tool interfaces and 44 skill files for ChatGPT Work.

Skills span documents, visuals, browser control, data analytics, plugins, and more. Each skill page reproduces its full SKILL.md source.

Skills include detailed usage guidance, such as when to use or avoid each one.
What commenters are saying
A top comment praises Simon Willison's contributions. Several commenters discuss the uniform aesthetic of AI-generated sites, noting the site follows explicit guidelines visible in its own skills. One comment highlights the control-browser skill, which launches Playwright via Node.js REPL and fetches runtime docs dynamically-a pattern that saves context and stays current. A meta-debate emerges over trusting OpenAI given safety-team departures and technical failures. Another commenter notes the sidebar doesn't scroll independently on smaller screens.
