# How Harper Reed actually uses coding agents

CEO 2389.ai, CTO Obama 2012

**If you take one thing:** `"fresh eyes" review`, a subagent rereads the code. his careful-review command sends a subagent back over new code with "fresh eyes". Jesse Vincent says he learned the trick from Harper.

> TMUX is the key that allows me to run a dozen Claude Code instances, and then walk away from my workstation, pick up my phone and continue hacking.
