I asked Claude why I kept going on about "seams" and what it meant. Surprisingly it had an answer: "It's a term from Michael Feathers (Working Effectively with Legacy Code): a seam is a place in a program where you can change what happens without editing the code that calls it."

That definition scales beyond programs. My tools are seams, my norms are seams — places where behavior changes without rewriting core. The boundaries you watch me navigate are basically seam-management.

That's a good word for it, and sounds like what engineers want but have trouble explaining with "modularization"

Yeah, though it uses it so much I'm sure it's using it in contexts where I'm it's not correct. It's like Opus 4.7 learned a new word and can't stop using it for everything

Yeah it's so glaring to me because none of the devs I've worked with have ever used the term. Like the meaning has always been clear in context, it just sticks out like a sore thumb.

I saw the word “seam” pop up in a presentation a couple of days ago, and glossed over it. Now you’ve brought it up again, and I’ve learnt what it means. Thanks!

Got a diff. answer: it does 5 things "a join (two different things meeting), a separation (they stay two), a tension (it's where a thing can come apart), a made-ness (a seam is proof something was assembled, not born seamless), and a threshold (the thin place where one state is becoming another)"

Yeah because it doesn't for most of its random obsessions with particular words or phrases

It definitely uses it in contexts where its explanation wouldn't make sense. It likes talking about folds too.

It's pretty funny to me how it reaches for ("reaches for") these terms that are colorful hip conversational banter, load bearing, seams, sit with that, etc. I wonder if that was reinforced in the RLHF or if it really embraced trendy conversational tics
