# `zsh: command not found: gh`

**Where it appears:** Terminal

**What it means:** Your computer can't find the GitHub CLI: it isn't installed, or the app started before you installed it.

## Likely causes

- The GitHub CLI isn't installed yet.
- The Claude app was already open during the install.

## Message for your agent

```text
You said “command not found: gh”. I've reopened the app. Check gh --version and guide me through installing it if it's still missing.
```

**Prevention:** Reopen the app after installing any tool.
