# How Boris Cherny actually uses coding agents

Created Claude Code

**If you take one thing:** `/go`, test, /simplify, open PR. one skill at the end of most prompts puts his verify-first rule into practice. Claude tests its own work end to end before it opens a PR.

## In their words

> Personally, I write a lot of my code from the iOS app. It's a convenient way to make changes without opening a laptop.

> The setup is straightforward: we have a Slack channel called proj-claude-maintains-apps. In it, Claude Tag runs a bunch of daily routines across iOS, Android, Desktop, web, CLI, and Agent SDK:

> This model is a pleasure to work with, and I've been using it for everything.

> I run 5 Claudes in parallel in my terminal.

> I read diffs when it's touching critical code, or code that's important to get right. I don't write the code.
