Or how to create better and more powerful prompts?

Trying to follow second brain when I open terminal and try to install to my windows PC this is what I get????

(Edited: Setting up my ‘second brain’ has made a world of difference. Claude is finally getting in sync with my voice.) I'm a wildlife pet portrait artist so my use for Claude may be a bit different than most here .I'm trying to train Claude into my voice for posting, in this case Pinterest. I have the pro version of Claude and am working in a Pinterst project in cowork. I am trying to train Claude by using examples I've used in chatGPT that have been proved very helpful. But Claude is still missing what I need it to give and suggest. I feel I am using up valuable useage, yet not getting any closer to training it. I have Claude for a year, so really want to utilize it to help with posting, but so far chatGPT is winning. It has been a frustrating weekend trying to train Claude in this project. So any suggestions on instructions I could give it would be appreciated. Should I breakdown ideas in smaller chunks?

Hey I have excel/ word/ ppt files as references and also working files (microsoft words & excels & google docs & sheets) but Claude insides Obsidian can't read them. Do you have any solutions?

Does anyone know why the prices are much more on the app over the web browser and why won't they let me upgrade on the web browser if I signed up on the app? This is probably a dumb question but im so confused 🤣 I will pay $140 for max but im not paying $175 for max. Im not a rich AI expert..... yet😏
