You may like this pattern of starting all custom commands with a comma - benefits against a wrapper command would be shorter command names and built-in tab completion.

This isn’t exactly what you’re going for since it isn’t automatic, but Apple is introducing NameDrop in iOS 17 which will allow you to share contact info by holding iPhones next to each other (similar to Bump back in the early 2010s). Of course NameDrop is closed to Apple devices which sucks (Android has Nearby Share, but it doesn’t default to sharing your contact), but the idea of being able to hold phones to each other to share contact info would be ideal for me - it’d be quick so I wouldn’t have to think about it and would be willing to do it for brief interactions, but also ensures my info is only shared with who I choose.

• pdfcrop (commonly included with LaTeX) for cropping margins - it cuts the pdf down to its contents then adds a margin of your choosing, extremely useful for forcing academic papers to have consistent margins, pdfcrop --margins 72 *pdf here* will create a document with a ~1in margin all around (it uses bp as its units)
• vips for resizing/converting images - it’s a bit faster and lighter than imagemagick in my experience, although the main reason I use it instead of imagemagick is just because I like playing around with stuff I haven’t used before :) It has an officially supported python binding too
