Tip: find -type f | xargs head (but no it's not comfy)

but I don't think going to "one giant metadatafile" argument helps; personally my attention starts splintering far sooner than that. Most of the time, if I'm looking at meta-data of an object, I'm not just looking at that single object, I'm reasoning about it in relation to other data points (maybe other objects in the same collection, maybe not). If at some point I want to shift my focus from created_at to updated_at or back, I need that transition to be as cheap as eye saccade. So by splitting the data to multiple files you are sort of setting "minimal tax" already pretty high.

That said, for simple projects where you want to have as few dependencies as possible, I think it's fine; it might or might not be better than raw-dogging your own format. I've actually implemented pretty much this format multiple times when I was coding predominantly in Bash. (Heck, eg. my JATS framework is pretty much using FAMF for test run state 😄 .) Just be careful: creating / removing files and directories can be a pretty risky operation -- make a typo in (or fail refactoring) a shell variable and you might be just rm -rf'ing your own "$HOME". It might be one of things you want to do less of, not more.

BTW, I chuckled because you turn from created_at to cre_at for no apparent reason. (I mean, if you like obscure variable names, fine by me, but then why would you call it created_at in the first file?)

BTWBTW, I love your site, I wish most of the web looked like that; the grey gives me sort of nostalgy :D Also you reminded me that I should give Kagi a try...
