I spend most of my day in Claude Code. It's my pair programmer, code reviewer, and rubber duck all rolled into one. After a few days of using it, I realized I had no idea how many tokens I'd burned, how much the session was costing, or how close I was to filling the context window.
Every once in a while I'd run /cost, think "that's higher than I expected," and go back to work.
That lasted about a day.
I like dashboards. If I'm consuming resources or spending money, I want to see it happening in real time. I don't want another command I have to remember to run. I want to glance at the bottom of my terminal and immediately know what's going on.
So I built a custom status line.
