Arize Trace
Fix Arize ax CLI profile and API key setup when LLM trace export fails with 401 or missing profile—without probing auth proactively on every session.
Overview
Arize-trace is an agent skill most often used in Operate (also Build integrations) that walks through ax CLI profile repair so Arize LLM tracing works after auth or region misconfiguration.
Install
npx skills add https://github.com/github/awesome-copilot --skill arize-traceWhat is this skill?
- Use only when authentication fails (401, missing profile, wrong API key)—not as a proactive checklist
- Inspect state with ax profiles show before create versus update decisions
- Patch profiles with ax profiles update without rewriting unrelated fields
- Requires API keys via ARIZE_API_KEY env var—never pass raw keys on the command line
- Region correction example uses us-east-1b for endpoint mismatches
Adoption & trust: 864 installs on skills.sh; 34.6k GitHub stars; 2/3 security scanners passed (skills.sh audits).
What problem does it solve?
Your agent traces stop exporting because the ax profile has no API key, the wrong region, or no profile at all.
Who is it for?
Indie agent builders already using Arize ax who see 401 or missing-profile errors during trace setup.
Skip if: Projects with no Arize account or teams that need full OpenTelemetry instrumentation design before choosing a vendor.
When should I use this skill?
Authentication fails for Arize ax (401, missing profile, missing or wrong API key, wrong region)—not for routine pre-flight checks.
What do I get? / Deliverables
A valid ax profile points at the correct region with ARIZE_API_KEY referenced safely so trace upload can succeed again.
- Working ax profile with correct region and key reference
- Restored ability to export traces after auth errors

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Operate is the default shelf because this skill is invoked when observability export is broken in a running workflow, not when ideating features. Monitoring fits Arize tracing and ax profile configuration that keeps agent runs observable in production-like environments.
Where it fits
Traces suddenly return 401 after rotating keys—patch the active ax profile with ARIZE_API_KEY.
First-time hookup of an agent feature to Arize export when ax profiles show reports no profile.
How it compares
Targeted auth runbook for the ax CLI—not a full observability platform comparison or MCP server.
Common Questions / FAQ
Who is arize-trace for?
Solo builders and small teams using Arize ax to export LLM traces who need to fix profiles and API keys when connections fail.
When should I use arize-trace?
During Operate when monitoring breaks on 401 or missing profiles; during Build integrations when first wiring ax export after deploying an agent feature.
Is arize-trace safe to install?
The skill instructs shell CLI usage and secret handling via env vars—review the Security Audits panel on this Prism page and never commit API keys to the repo.

# 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
