What it does
Otel Node is an agent skill from mizchi/skills. Node.js OpenTelemetry setup — SDK init, auto-instrumentation packages, and the esbuild ESM silent-failure gotcha (instrumentation- packages produce no spans when bundled with esbuild --format=esm). Use when adding OTel to a Node.js/Hono/Express service or debugging missing spans after bundling. See opentelemetry for signal design decisions.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in DevOps & Cloud, covering Observability and Architecture decision records. It works with OpenTelemetry, Hono and Node.js. The repository describes itself as: Agent skills by mizchi, distributed via APM.
When your agent uses it
- Adding OTel to a Node.js/Hono/Express service
- Debugging missing spans after bundling
Example prompts
- “/otel-node”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 62f5808. 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:
pnpmnodetsx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
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 Node loads about 1.3k tokens when it runs. Until then it costs about 88 tokens; SKILL.md has 270 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 270 words (~1,321 tokens).
“Load before the app entry: node --import ./otel.js server.js or tsx --import ./otel.ts server.ts.”
