Pointing overlay solves a problem that doesn't need an agent

Genuine question… Why does this need to be a skill? Literally just ask Claude to “call out actions in these screenshots with numbered stylized arrows” and you get the same thing…

Arrow design looks odd
From 3 comments
"It is an arrow, so we spent an unreasonable amount of time on how it looks." Brilliant. This is exactly the kind of content I seek when I visit Hacker News. Truly art.

Youtube tutorials and screenshots in docs
From 2 comments
I don't disagree. But the existing tech solution - scrubbing through YouTube tutorial videos until I cobble together the bits of knowledge I need - is also quite overengineered,…
alanbernstein on HNThis could be great for documentation. Screenshots in docs are frequently useless because they show me a screen and say "click X" where I still have to search X visually. And I…
