Timed my agent for a day. it was actually running about a quarter of that, rest was waiting on me to hit approve

Contract backend work, one big Django codebase plus a few smaller services. Been running agents on it all year, Claude Code mostly. Timed a day last week out of curiosity. Agent was actually working maybe two and a half hours out of eight. Rest sat on an approval prompt. Write outside the working dir, run the tests, install a package, same handful of things over and over. Four seconds to click if I'm at the desk. I'm often not at the desk. Tried MiniMax Code mainly because it has a phone client. Hand it a long task as a goal and it keeps going, phone shows what's waiting on you. Tuesday I gave it a refactor I'd been avoiding since spring, pulling payment handling out of a views module that had gotten away from us. Mostly my fault. Then left the house. Six questions over the morning. Approved a write outside the working dir standing on a train platform, which felt stupid. Signal died in the tunnel and terminal output came back half a minute behind, more annoying than it sounds. Sat down at work and it was done. Wouldn't want to actually edit code on a phone though. Reading and tapping approve is about the ceiling. Verifier pass afterwards flagged two error paths with nothing testing them. I'd have missed those. Still don't think I've got the shape of this right. What's everyone else doing about approvals?
