I actually created one simple agent back then on Val Town that checks any new sign ups to my app and then posts to Slack. It was free but I've never created anything else on their platform.

I kind of liked their story and wanted to support them. Their UX wasn't great for one. But I think the bigger problem is that the big opportunity for them was that they started early before it was crowded, and if they didn't capture a big market share then, now it's too late and impossible to compete. For agents to be useful you need to integrate them with all your services and data, and if you're already using a trusted provider Like Claude or ClaudeFlare etc. then it's easy just to stick with their offerings.
