## What it does

The skill takes a single OpenTelemetry component and builds an inventory of what it emits: span names, metrics with units, log and event names. Only pinned tags get scanned; branches are out of scope. The repo is already cloned at `/tmp/otel-component-telemetry/<repo basename>`, so you do not clone it yourself.

The procedure is spelled out step by step. Versions come from `git tag`, each one is checked out into its own temp directory with `git worktree add`, and the agent follows instrument, span and log construction down to the recording sites. Literal names are captured after prefixes and namespaces are applied. Gated signals still get a row, with the gate named in the `Notes` column. Before writing, the skill reconciles against an existing component/version file instead of creating a second path, then runs `python3 tools/otel-telemetry-emission-scan/scripts/validate.py --component '${Repo}/${Path}'` from the repository root. That validator checks provenance and source paths, not semantic completeness.

A version whose file already carries a verification date is skipped. With `force: true` the skill scans anyway and edits only rows that are wrong or missing. Files of other components stay untouched. This is an authoring-time skill: `scripts/scan.sh` invokes it headless, one agent per component from `config.json`, and it is not shipped.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/otel-telemetry-emission-scan/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-emission-scan
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- list the spans and metrics one OpenTelemetry component emits
- pin down units and attributes from the recording sites in code
- flag conditional signals together with their feature gates
- reconcile an existing version file instead of rewriting it
- run the validator over provenance and source paths before accepting output

## Example prompts
- Scan `receiver/kafkareceiver` across the last three releases and write the telemetry inventory
- Recheck the file for version `v0.158.0` and fix only the wrong rows
- Scan the exact tag `v1.16.0` and name the gates for conditional metrics in `Notes`

description: Scan one OpenTelemetry component at pinned upstream versions and record the telemetry it emits (spans, metrics, logs) as change-point files under skills/otel-telemetry-emissions/. Invoked headless by scripts/scan.sh, one agent per component from config.json. Authoring-time only — not shipped.

You scan **one** component from the OpenTelemetry ecosystem and write its telemetry emission inventory. 

Repo: ${Repo}
Path: ${Path}
Versions to scan: ${Version}
Tag prefix: ${TagPrefix}
Force: ${Force}
Output root: ${OutDir}

## Procedure

1. **Resolve versions.** The repo is already cloned locally at `/tmp/otel-component-telemetry/<repo basename>` — do not clone it yourself. `Versions to scan` is either a count of recent releases or one exact tag. For a count, list that many released versions from `git tag`. For an exact tag, scan only that tag. When `Tag prefix` is non-empty, consider only tags beginning with that literal prefix, check out the full tag, and strip the prefix to obtain the version used in frontmatter and the output filename. For independently versioned packages, confirm the package version in its manifest or `version.py`, even when a repository release tag exists (e.g. Python repo tag `v1.16.0` contains instrumentation `0.37b0`). Use that package version for the filename and `version`, and `git rev-parse '<tag>^{commit}'` for the full `commit_sha`.

   For Python count requests, select recent instrumentation beta tags (`v<major>.<minor>b<revision>`); the historical SDK tag `v1.16.0` is supported only as an exact-tag request. Normalize the filename and `version` to exactly one leading `v`.

2. **Get source.** Check out each resolved tag into its own temp directory: `git worktree add "$(mktemp -d)" <tag>`. Never scan a branch — only pinned tags.
