Claude AI v Cowork v Code
Hey @Kj Rainey have you planned a video about Claude AI vs Cowork vs Code, when to use each? how to implement them in a Second Brain structure? What would be the most efficient workflow? I’m curious to hear. Thanks!

@Kj Rainey love the approach. I’m in!
Workspace VM disk space full
Hey @Kj Rainey I’m on a Pro plan and it seems I hit the workspace VM disk max capacity. This won’t allow some of the activities to run, do you know how to fix it? Claude only advises to report to Anthropic as a bug, I checked a Reddit saying to review the VM usage space by running a command in the terminal. I did that and my usage looks ok from the output I got, yet the operations keep failing due to lack of VM disk space. I’d appreciate any suggestions and word of advice 🙏
Token usage efficiency
@Kj Rainey I noticed that although I can manage the hourly usage pretty effectively, I consume a lot of the weekly one (30% already and it resets next Sat). Does it mean I got the process working efficiently by using the 2 layers system, but I do use it a lot overall? As I am actually building stuff with it, would it make sense to upgrade to the Pro, or maybe you have some extra hints to give - a part of having a dedicated Claude.md for each specific project, a dedicated folder per project, connectors and skills enabled only when needed? Thanks man!

@Kj Rainey Man I didn’t get there yet and just watched the whole video. That’s soooo cool! It’s exactly how I’m doing and how I’m feeling when I hit the max. With a little difference, I’m using the forced rest as a detox as I’m worried i wouldn’t leave my desk otherwise 😂 On top, I created a handoff/pickup skill that saves me a lot of time and usage: every time I finish part of my project I run /handoff and it creates a full note of that chat session; then I open a new task for the next step of the project and run /pickup and Claude starts with full context and only important info, no fluff. I think I’ll need to upgrade soon, though. Thanks man for such a valuable community! God bless you and your family! 🙏
Should I create a skill in the cowork homebase or should I create a new folder
Hello, I want to create a skill for lead sourcing(since I honestly hate it), And I was wondering, should I put this skill in the cowork homebase second brain KJ gave us, or is it more efficient to create a whole new folder for each skill. which one wastes the least tokens?

If i understood correctly @Kj Rainey’s set up, you should use the second brain as main character (imagine it to be your CEO who doesn’t need to know the process of their accounting department), then you get specific agents with detailed responsibilities and skills (the heads of departments and expert employees). The latter are the ones you want to know how exactly how to process the action. The CEO doesn’t need to know and wouldn’t be wise to overload it with such info. At least, that’s how I built my system. Yet, usage consumption is still a big limit to my daily operations. Hope it helps! 🤙🏻
