## What it does

The skill gives the agent five self-contained references instead of one long document. Declarative setup covers YAML config through `opentelemetry-configuration`: `load_config_file`, `configure_sdk`, environment substitution, `OTEL_CONFIG_FILE`. The API reference lists import paths, tracer, meter and logger usage, propagation, and the `LoggingHandler` bridge that ties Python logs to traces. A third file walks through zero-code instrumentation with `opentelemetry-distro`, `opentelemetry-bootstrap` and `opentelemetry-instrument`, plus the contrib catalog and manual instrumentation.

Two more references handle tuning and breakage. Performance covers sampling, the batch span processor, periodic metric reader, views, asyncio context, exporters and graceful shutdown. The breaking-changes file is for auditing existing code against renamed or deprecated APIs and semantic convention shifts.

Version facts are not baked in. The agent is told to fetch PyPI for `opentelemetry-sdk`, `opentelemetry-configuration`, `opentelemetry-distro`, `opentelemetry-exporter-otlp` and contrib packages, and to pull the YAML schema from the `otel-declarative-config` skill. The bundled references reflect release 1.45.1 and contrib 0.66b1, so on a pinned older SDK expect answers that no longer match your code.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ollygarden/opentelemetry-agent-skills --skill otel-python -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ollygarden/opentelemetry-agent-skills --skill otel-python -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ollygarden/opentelemetry-agent-skills --skill otel-python -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ollygarden/opentelemetry-agent-skills otel-python
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ollygarden/opentelemetry-agent-skills --skill otel-python -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ollygarden/opentelemetry-agent-skills --path skills/otel-python
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ollygarden/opentelemetry-agent-skills --skill otel-python -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/ollygarden/opentelemetry-agent-skills/tree/HEAD/skills/otel-python/SKILL.md

## When to use it
- Wire up TracerProvider and MeterProvider in a Python service
- Turn on auto-instrumentation for FastAPI, Flask or Django without editing app code
- Move SDK configuration to declarative YAML
- Connect Python logs to traces with LoggingHandler
- Audit code for renamed APIs after an SDK upgrade

## Example prompts
- Set up OpenTelemetry in my FastAPI service using declarative YAML
- Why doesn't `opentelemetry-instrument` pick up my Flask app?
- Check this code for deprecated OpenTelemetry APIs after the SDK bump
