# Instrument

> Set up Arize AX tracing with your coding agent using the AX CLI

The `ax instrument` command sets up Arize AX tracing with your coding agent. It chooses a coding agent, installs the AX CLI and the Arize skills so the agent can use them, then launches it with a guided setup that takes you from Arize signup to your first traces.

## `ax instrument`

Launch the guided onboarding flow.

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
ax instrument
```

The command runs interactively — it detects and lets you choose a coding agent, installs the CLI and Arize skills, and hands off to the agent to walk you through configuring tracing and sending your first traces.

**Examples:**

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Run with the CLI already installed
ax instrument

# Run with nothing installed yet
uvx arize-ax-cli instrument
```
