opentelemetry-llm

opentelemetry-llm is a skill for Claude Code from a5c-ai/babysitter. It costs 18 tokens per session (393 once invoked), scanned A, original, MIT.

OpenTelemetry instrumentation for AI applications, adding traces that show how requests move through models and services. Traces can be sent to tools such as Jaeger or OTLP-compatible systems.

In plain words
What is it for?
It is for recording model calls, token and model details, errors, and request context across distributed AI applications.
Why use it?
It makes slow requests, failures, and relationships between services easier to investigate instead of leaving only isolated log messages.

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-llm 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 29d 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 LLM Skill

Capabilities

  • Configure OpenTelemetry SDK for LLM apps
  • Implement LLM-specific instrumentation
  • Set up trace exporters (Jaeger, OTLP)
  • Design semantic conventions for LLM

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
