I posted a Show HN post recently. It has not had a single glance of interest. I think it is dead now anyway. I've spent months on the project I posted, but no interest from anyone.
I've used it to read authenticated pages with Chromium.
It can be run as a headless browser and convert the HTML to markdown, but I generally open Chromium, authenticate to the system, then allow the CLI agent to interact with the page.
I put an unsecured open FTP server on the internet about 20 years ago, just to see what would happen.
Within half a day I had some pirate "marking" his claim to my FTP server, then he/she started uploading a game. I deleted everything and left it open again.
It was a long time ago, so I don't remember all the details, but all the pirates would create directories inside directories, upload files, then mark it with their mark. All of this was scripted I gather.
After a while, I set up a file system watcher that deleted subdirectories. This gave me an FTP server I could use for anything. I shut it down a few months later.
Using it I don't need skills, memory, subagents, a specific agent CLI. It defines roles, tasks, context out of the box.
I made it for me and my family though. I don't expect interest outside of that.
