# arize-instrumentation

This skill adds Arize AX tracing to an LLM app: it detects the stack, wires auto-instrumentation and verifies that traces land.

## What it does

The skill runs in four steps: read the manifests and imports, fetch the one matching integration doc, wire auto-instrumentation, confirm a trace arrives. Phase one is read-only — no code or files get touched. In a monorepo or a project with several services it asks which target to instrument instead of picking one for you.

Routing follows the framework, not the provider SDK it wraps. An agent-framework app that imports `openai` somewhere is not a provider-page case. When the stack is missing from the routing table, the skill searches `llms.txt` for its integration page, and falls back to manual instrumentation when nothing matches.

You never paste secrets into the chat. The skill references `ARIZE_API_KEY` and `ARIZE_SPACE_ID`, which you set yourself in `.env` or your shell. It preserves or asks for the app's Arize region and export endpoint rather than assuming US. A project name is required — without it the request fails with HTTP 500, and `service.name` alone is not enough. Go has no integration doc, only a reference for install, wiring and manual spans.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Arize-ai/arize-skills --skill arize-instrumentation -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/arize-instrumentation/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/arize-instrumentation/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Arize-ai/arize-skills --skill arize-instrumentation -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/arize-instrumentation/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Arize-ai/arize-skills --skill arize-instrumentation -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/arize-instrumentation/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Arize-ai/arize-skills arize-instrumentation
```

2. **Manually: put the files in place**
- File: `.github/skills/arize-instrumentation/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Arize-ai/arize-skills --skill arize-instrumentation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Arize-ai/arize-skills --path skills/arize-instrumentation
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/arize-instrumentation/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Arize-ai/arize-skills --skill arize-instrumentation -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Arize-ai/arize-skills/tree/HEAD/skills/arize-instrumentation/SKILL.md

## When to use it
- add Arize AX tracing to an LLM app from scratch
- detect the stack and fetch the single matching integration doc
- wire auto-instrumentation without touching business logic
- filter generic HTTP spans so they don't flood the project
- add TOOL and CHAIN spans where no instrumentor covers them

## Example prompts
- Instrument this app with Arize AX tracing and verify a trace lands
- Detect my stack and wire Arize auto-instrumentation; I'll set the keys in `.env` myself
- For my raw Anthropic SDK app, add a TOOL span per tool call and a CHAIN span for the turn

description: Adds Arize AX tracing to an LLM application for the first time. Detects the stack, routes to the single matching integration doc, wires auto-instrumentation after user confirmation, and verifies traces land. Use when the user wants to instrument their app, add tracing from scratch, set up LLM observability, integrate OpenTelemetry or openinference, or get started with Arize tracing.

# Arize Instrumentation Skill

Add **Arize AX tracing** to an app for the first time: **detect the stack → fetch the one matching integration doc → wire auto-instrumentation → verify a trace lands.**

**Route locally.** Map the detected stack to a single doc page via [references/integration-routing.md](references/integration-routing.md) and fetch **only that page**. When the app uses an agent framework, route on the **framework**, not the provider SDK it wraps — a bare `openai`/`anthropic` import inside a framework app is not the integration target; route to a provider page only when the app calls the provider SDK directly with no framework in play. When the stack isn't listed there, search [llms.txt](https://arize.com/docs/llms.txt) for its integration page per the router; with no match, use [manual instrumentation](https://arize.com/docs/ax/instrument/manual-instrumentation). Never bulk-read the [PROMPT.md](https://arize.com/docs/PROMPT.md) aggregate.

**Rules:** inspect before mutating; tracing is additive, never change business logic; follow existing style; no secrets in code and **never ask the user to paste secrets (API keys, tokens) into the chat** -- reference `ARIZE_API_KEY`/`ARIZE_SPACE_ID` env vars only, set by the user in their own `.env`/shell; preserve or ask for the app's Arize region/export endpoint instead of assuming US -- see [references/regions-and-endpoints.md](references/regions-and-endpoints.md); ask before persistent local state (`ax` profiles, `.zshrc`, env vars) -- see [references/ax-profiles.md](references/ax-profiles.md).
