## What it does

The skill equips coding agents with a structured inventory of OpenTelemetry signals across specific releases. It catalogs components from collector repositories and instrumentation packages, storing each version in a separate markdown file like `opentelemetry-collector-contrib/receiver/kafkareceiver/v0.158.0.md`. The agent starts at `index.md` to locate exact versions or pick the closest prior release.

Data files outline trace spans, metric instruments with units, and log events alongside required attributes. The `scope_name` field records the instrumentation scope so runtime records match their components. In addition, conditional telemetry gated behind feature flags is documented in notes tables.

Because entries stem from automated LLM analysis of upstream repositories, double-checking against the original source code remains necessary for sensitive production setups.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- Inspect spans and metrics for an OpenTelemetry receiver at an exact version
- Audit attribute changes before upgrading collector components or SDKs
- Identify the correct instrumentation scope name for incoming logs
- Check which metrics require opt-in flags or experimental semantic conventions

## Example prompts
- Show all metrics and spans emitted by kafkareceiver in version v0.158.0
- Check if the telemetry changed between the current and target SDK versions
- Look up the instrumentation scope name for this collector component

description: Version-pinned inventory of the telemetry (spans, metrics, logs, attributes) emitted by OpenTelemetry collector components and SDK instrumentation packages. Use when working with a covered component — what it emits at a given version, or how emission changed across versions — and when upgrading a component or SDK version, to see the telemetry after the change.

# Telemetry Emissions

A registry of what telemetry OpenTelemetry components actually emit, pinned to
upstream versions.

> **Note:** The telemetry emissions in these files were detected by LLM
> analysis of the upstream source and may contain errors. Verify against the
> component's source or docs before relying on a row for critical decisions.

## Layout

```
<repo basename>/<path in repo>/v<version>.md
```

Example: `opentelemetry-collector-contrib/receiver/kafkareceiver/v0.158.0.md`

One file per scanned version. The files in a component directory are its
telemetry history; `index.md` lists every file — start there to see what is
covered.

## Looking up a component at a version

1. Find the component's directory (or its row in `index.md`).
2. Pick the file matching the target version exactly.
3. If there is no exact match, use the file with the highest version below the
   target and say the exact version is unverified.
4. If the component or version is not covered at all, say so — do not infer
   telemetry from semantic conventions.

## What a data file contains

Frontmatter (`repo`, `path`, `version`, `scope_name`, `commit_sha`,
`last_verified`), then per-signal tables:

- **Traces** — span name, kind, attributes, notes
- **Metrics** — metric name, instrument type, unit, attributes, notes
- **Logs** — log/event name, attributes, notes

`scope_name` is the component's instrumentation scope — the anchor for
matching runtime telemetry back to the component. When helper or pipeline
telemetry uses another scope, its rows name that scope in `Notes`.
`last_verified: null` means the historical verification date could not be
substantiated; recheck the pinned source before presenting its rows as verified.
Absent signals are omitted
entirely. `Notes` marks conditional emission (feature gates, opt-in config,
experimental semconv). `Sources` lists the upstream files the data came from.
