"Sequential thinking" is one that I tried recently because so many people recommend it, and I have never, ever, seen the chatbot actually do anything but write to it. It never follows up any of it's chains of thoughts or refers to it's notes.
In which client and with which LLM are you using it?
I use it in Claude Desktop for the right use case, it's much better than thinking mode.
But, I admit, I haven't tried it in Cursor or with other LLMs yet.
