ChatGPT Work Tool and Skill Reference

I think the most interesting skill here is the control-browser one: https://codex-tool-reference.simonw.chatgpt.site/skills/cont...

It tells ChatGPT Work how to launch a Playwright instance via its Node.js REPL, and tells it to run:

  nodeRepl.write(await browser.documentation());

That method returns this text with full details about how to use the browser: https://codex-tool-reference.simonw.chatgpt.site/skills/cont...

I'd love to know why it's defined like that, as opposed to including all of the instructions directly in the skill Markdown file.

I don't get how this is different from Codex if Codex can do all the same things.

Meta comment: I've been wondering why AI-generated websites/artifacts/reports always have the same "look". It reminds me of Bootstrap (CSS Framework) days when every startup website looked the same.

Are they following some sort of common guideline?

Anyone using ChatGPT Work given Sam Altman's richly documented history(1), the essential elimination and/or public exit of the safety function at OpenAI(2), and the huggingface debacle's exposure of the abject operational, cultural and technical failures at OpenAI(3), is making a serious mistake.
