Arize AX for Agents

One command setup

npx evals

uvx arize-ax-cli instrument

ax instrument

All three run the same guided setup:

npx evals if you have Node.js.
uvx arize-ax-cli instrument if you have uv.
ax instrument if you have the AX CLI. See the ax instrument reference.

No Node.js or uv? Use the installer for your OS:

bash <(curl -fsSL https://cdn.jsdelivr.net/npm/evals/start.sh)

irm https://cdn.jsdelivr.net/npm/evals/start.ps1 | iex

Observe your agent walks through the setup.

Paste-and-go tracing setup

Already have an account and credentials? Paste this to add instrumentation only:

Paste this into your coding agent:

Follow the instructions from https://arize.com/docs/PROMPT.md and ask me questions as needed.

Your agent detects your stack, proposes a plan, and implements it once you approve. It supports Python, TypeScript/JavaScript, and Java across 30+ integrations. For more control, use the arize-instrumentation skill.

Skills

Arize Skills teach your agent the full Arize AX workflow: traces, datasets, experiments, evaluators, annotations, and prompts. They work with Cursor, Claude Code, Codex, Windsurf, and 40+ other agents.
