I've re-created all my productivity techniques which I use for the last 8 years as AI skills. Nothing fancy - just a bunch of markdown files, and you'll still have to do all the thinking work by yourself (sorry). Actually you don't have to use AI with them, they're working great with a notepad and a pen too, but it's up to you to decide.
I cannot live without my personal task manager and daily / weekly routines which I do to keep my life organised. Maybe because I cannot stand of unfinished / disorganised tasks anymore, maybe it's just a good habit I've developed over the years. I've called them "clear head" because surprise-surprise, they help me keep my head clear It's especially relevant in the AI era we're in where we have to process a lot of information (yes, I see the irony that AI skills can help with an overloaded mind because of AI, but they can ).
Please check them out and let me know if they were useful for you, and it's open-source so you can contribute.
