Arize Trace
Fix Arize `ax` CLI auth and profile settings when traces fail with 401 or missing API key—not for day-to-day trace analysis.
Overview
Arize Trace is an agent skill for the Operate phase that repairs Arize `ax` CLI profiles and API-key configuration when authentication fails.
Install
npx skills add https://github.com/arize-ai/arize-skills --skill arize-traceWhat is this skill?
- Diagnose missing profile, unset API key, wrong region, or 401 via `ax profiles show`
- Patch only broken fields with `ax profiles update` while preserving other settings
- Never pass raw API keys on the CLI—always reference exported `ARIZE_API_KEY`
- Create a new profile when none exists or a full re-point is needed
- Explicit anti-pattern: do not run these checks proactively—only when authentication fails
- 3-step flow: inspect → update → create profile

What problem does it solve?
Your agent or pipeline cannot send or query Arize traces because the `ax` profile is missing, the API key is unset, or you get 401 Unauthorized.
Who is it for?
Indie builders using Arize for LLM tracing who hit 401, empty profiles, or wrong-region errors mid-debug.
Skip if: Proactive observability setup, writing trace queries, or debugging application logic when auth already works.
When should I use this skill?
Authentication fails (401, missing profile, missing API key)—do not run proactively.
What do I get? / Deliverables
A valid `ax` profile with the correct region and API key reference is configured so tracing commands authenticate again.
- Corrected or new `ax` profile with API key and region
Recommended Skills
Journey fit
Observability credentials break in production and block LLM trace ingestion; canonical shelf is operate because the skill only runs after auth/profile errors surface. Monitoring covers LLM tracing backends; profile repair unblocks telemetry pipelines without changing application code.
How it compares
Credential repair for the `ax` CLI—not a full Arize onboarding or dashboard analytics skill.
Common Questions / FAQ
Who is arize-trace for?
Solo and indie developers who run the Arize `ax` CLI for LLM tracing and need to fix profile or API-key errors without exposing secrets on the command line.
When should I use arize-trace?
Use it in Operate when monitoring breaks due to auth: after 401 responses, "No profiles found", or a profile showing API Key (not set)—not before every trace session.
Is arize-trace safe to install?
It instructs shell commands and secret handling via environment variables; review the Security Audits panel on this Prism page and never paste API keys into chat or CLI flags.

# ax Profile Setup Consult this when authentication fails (401, missing profile, missing API key). Do NOT run these checks proactively. Use this when there is no profile, or a profile has incorrect settings (wrong API key, wrong region, etc.). ## 1. Inspect the current state ```bash ax profiles show ``` Look at the output to understand what's configured: - `API Key: (not set)` or missing → key needs to be created/updated - No profile output or "No profiles found" → no profile exists yet - Connected but getting `401 Unauthorized` → key is wrong or expired - Connected but wrong endpoint/region → region needs to be updated ## 2. Fix a misconfigured profile If a profile exists but one or more settings are wrong, patch only what's broken. **Never pass a raw API key value as a flag.** Always reference it via the `ARIZE_API_KEY` environment variable. If the variable is not already set in the shell, instruct the user to set it first, then run the command: ```bash # If ARIZE_API_KEY is already exported in the shell: ax profiles update --api-key $ARIZE_API_KEY # Fix the region (no secret involved — safe to run directly) ax profiles update --region us-east-1b # Fix both at once ax profiles update --api-key $ARIZE_API_KEY --region us-east-1b ``` `update` only changes the fields you specify — all other settings are preserved. If no profile name is given, the active profile is updated. ## 3. Create a new profile If no profile exists, or if the existing profile needs to point to a completely different setup (different org, different region): **Always reference the key via `$ARIZE_API_KEY`, never inline a raw value.** ```bash # Requires ARIZE_API_KEY to be exported in the shell first ax profiles create --api-key $ARIZE_API_KEY # Create with a region ax profiles create --api-key $ARIZE_API_KEY --region us-east-1b # Create a named profile ax profiles create work --api-key $ARIZE_API_KEY --region us-east-1b ``` To use a named profile with any `ax` command, add `-p NAME`: ```bash ax spans export PROJECT -p work ``` ## 4. Getting the API key **Never ask the user to paste their API key into the chat. Never log, echo, or display an API key value.** If `ARIZE_API_KEY` is not already set, instruct the user to export it in their shell: ```bash export ARIZE_API_KEY="..." # user pastes their key here in their own terminal ``` They can find their key at https://app.arize.com/admin > API Keys. Recommend they create a **scoped service key** (not a personal user key) — service keys are not tied to an individual account and are safer for programmatic use. Keys are space-scoped — make sure they copy the key for the correct space. Once the user confirms the variable is set, proceed with `ax profiles create --api-key $ARIZE_API_KEY` or `ax profiles update --api-key $ARIZE_API_KEY` as described above. ## 5. Verify After any create or update: ```bash ax profiles show ``` Confirm the API key and region are correct, then retry the original command. ## Space There is no profile flag for space. Save it as an environment variable — accepts a space **name** (e.g., `my-workspace`) or a base64 space **ID** (e.g., `U3BhY2U6...`). Find yours with `ax spaces list -o json`. **macOS/Linux** — add to `~/.zshrc` or `~/.bashrc`: ```bash export ARIZE_SPACE="my-workspace" # name or base64 ID ``` Then `source ~/.zshrc` (or restart terminal). **Windows (PowerShell):** ```powershell [System.Environment]::SetEnvironmentVariable('ARIZE_SPACE', 'my-workspace', 'User') ``` Restart terminal for it to take effect. ## Save Credentials for Future Use At the **end of the session**, if the user manually provided any credentials during this conversation **and** those values were NOT already loaded from a saved profile or environment variable, offer to save them. **Skip this entirely if:** - The API key was already loaded from an existing profile or `ARIZE_API_KEY` env var - The space was already set via `ARIZE_SPACE` env var - The user only used base64 pr
