What it does

Otel JS is an agent skill from ollygarden/opentelemetry-agent-skills. OpenTelemetry in Node.js / JavaScript / TypeScript — NodeSDK, declarative YAML configuration, auto-instrumentations, ESM vs CJS import patterns. Use when adding, reviewing, or configuring OpenTelemetry in a Node.js service. Triggers on "setup otel in node", "js telemetry", "node tracing setup", "NodeSDK", "auto instrumentation node", "TracerProvider node", or any Node.js-related OTel question.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/declarative-setup.md`).

It sits in DevOps & Cloud, covering Observability. It works with OpenTelemetry, Node.js, JavaScript and TypeScript. The repository describes itself as: Vendor-neutral OpenTelemetry skills for AI coding agents like Claude Code, Cursor, and Codex, grounded in upstream sources. The licence is Apache-2.0.

When your agent uses it

Example prompts

“setup otel in node”
“js telemetry”
“node tracing setup”
“/otel-js”

Requirements

What it can do on your machine

Read from SKILL.md and the folder at commit 12296db. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- raw.githubusercontent.com
- opentelemetry.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Otel JS loads about 655 tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 143 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~101
When it runs · the whole SKILL.md, loaded when a task matches: ~655
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Otel JS is an agent skill from ollygarden/opentelemetry-agent-skills.js / JavaScript / TypeScript — NodeSDK, declarative YAML configuration, auto-instrumentations, ESM vs CJS import patterns.

When should I use Otel JS?

Otel JS fits situations like: configuring OpenTelemetry in a Node.js service; setup otel in node; Node tracing setup; auto instrumentation node.

How do I install Otel JS in Claude Code?

Run `npx skills add ollygarden/opentelemetry-agent-skills --skill otel-js -a claude-code`. Or copy the skill folder (skills/otel-js in ollygarden/opentelemetry-agent-skills) into .claude/skills/otel-js in your project. Claude Code loads it when a task matches its description.

How do I install Otel JS in Codex?

Run `npx skills add ollygarden/opentelemetry-agent-skills --skill otel-js -a codex`. Or copy the skill folder (skills/otel-js in ollygarden/opentelemetry-agent-skills) into .agents/skills/otel-js in your project. Codex loads it when a task matches its description.

Can I use Otel JS in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ollygarden/opentelemetry-agent-skills --skill otel-js -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/otel-js, .gemini/skills/otel-js, .github/skills/otel-js and .opencode/skills/otel-js in your project.

What does Otel JS need to run?

Going by SKILL.md and its folder, Otel JS needs the command-line tools its instructions call (npm). Our summary lists: Node.js.

Does Otel JS access the network?

SKILL.md names 2 domains. In commands or code: raw.githubusercontent.com and opentelemetry.io; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.

Is Otel JS safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Otel JS use?

Otel JS is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Otel JS use?

About 655 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.8k tokens, read only when the agent opens those files.

What are the alternatives to Otel JS?

Skills that share tags, products or a category with Otel JS: Azure Monitor Opentelemetry TS (microsoft/skills, 3.1k stars), Logfire Instrumentation (basicmachines-co/basic-memory, 4.1k stars), Applicationinsights Web TS (microsoft/skills, 3.1k stars) and Sls Dashboard Builder (alibaba/loongsuite-pilot, 201 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Otel JS?

ollygarden (a GitHub organization) maintains it in ollygarden/opentelemetry-agent-skills, which has 106 GitHub stars. The repository holds 19 skills in this directory. The repository was last updated on October 10, 2026.
