opentelemetry

opentelemetry is a skill for Claude Code from bendrucker/claude. It costs 27 tokens per session (394 once invoked), scanned A, original, MIT.

A set of conventions for adding OpenTelemetry tracing to software. OpenTelemetry is a common way to record requests and operations as traces so their behavior can be inspected later.

In plain words
What is it for?
Use it when instrumenting HTTP requests, database operations, remote calls, or messaging, and when testing the spans those operations produce.
Why use it?
It prevents inconsistent trace names, attributes, error states, and tests that make recorded data hard to search or compare.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

opentelemetry scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

OpenTelemetry

Span Naming

Use short, low-cardinality names from semantic conventions:

  • HTTP: GET /users/{id} (method + route template, never full URL path)
  • DB: SELECT users (operation + table)
  • RPC: grpc.health.v1.Health/Check
  • Messaging: orders process (destination + operation)

Attributes

Use semantic convention attribute names — never invent your own:

  • HTTP: http.request.method, url.full, http.response.status_code, server.address
  • DB: db.system, db.statement, db.namespace
  • General: error.type, service.name

Import from the versioned semconv package (e.g., go.opentelemetry.io/otel/semconv/v1.x).

Status

Only set status on errors: span.SetStatus(codes.Error, err.Error()). Never set Ok — unset is the success state. Call RecordError alongside SetStatus; it only adds a span event, doesn't change status.

For HTTP: 4xx is Error on client spans, Unset on server spans. 5xx is always Error.

Testing

Use in-memory exporters with SimpleSpanProcessor (not batch — batch introduces timing). Assert on exported spans' names, attributes, and status. No mocking needed.

Boundaries

Instrument network calls, I/O, and queue operations — not every function. Use span events (AddEvent) instead of separate log statements for events within a traced operation.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
