Earlier quoted context omitted.

That structured CLI already exists: PowerShell cmdlets.

Not in any meaningful, general way on Unix systems it doesn't. Nobody uses psh outside Windows

But nobody is using your hypothetical "structured CLI-based --help-equivalent consumable by LLMs and shell completion engines alike" either. In terms of mindshare, you're starting from scratch either way.

I just remembered docopt, which maybe fits the bill in a more Unixy way, but it and its ports are mostly abandoned, for various reasons.

I use Playwright to intercept all requests and responses and have Claude Code navigate to a website like YouTube and click and interact with all the elements and inputs while recording all the requests and responses associated with each interaction. Then it creates a detailed strongly typed API to interact with any website using the underlying API. Yes, I know it likely breaks everybody's terms of service but at the…

I do this via BrowserOS -- https://github.com/browseros-ai/BrowserOS

It has an in-built MCP server and I use it with claude code, codex and like it quite a lot.

I love how HN is loving this idea when it's the exact same thing Anthropic and OpenAi (and every other llm maker) did. It's God's gift to them when it lets them bypass ads and dl copyrighted material. But it's Satan's curse on humanity when the Zuck does it to train his llm and dl copyrighted material.

I think there's a little bit of the Goomba fallacy at play here to be fair

I also do this. My primary use case is for reproducing page layout and styling at any given tree in the dom. So, capturing various states of a component etc. I also use it to automatically retrieve page responsiveness behavior in complex web apps. It uses playwright to adjust the width and monitor entire trees for exact changes which it writes structured data that includes the complete cascade of styles relevant with…

You should try my SnipCSS Claude Code plugin. It still uses MCP as skill (haven't converted to CLI yet), but it does exactly what you want for reproducing designs in Tailwind/CSS at AI speeds.

With our rtrvr.ai Extension we are actually about to allow anyone to do this with just prompting:

- the agent takes actions on a page

- network calls recorded

- agent writes script to hit endpoints directly at scale

- requests made from main world of webpage so automatically get auth headers added

Basically what you do manually but done via the agent in a minute and for FREE from an AI Studio API key
