What Instrument does

Instrument adds Opik tracing to an existing Python or TypeScript app and verifies a real trace lands. It is used when you need to add observability to an LLM workflow, then confirm the trace in Opik and return the trace link.

Instrument is cataloged under AI Engineering on DirSkills. Instrument comes from a repository tagged claude-code, generative-ai, llm-observability, mcp and mcp-server.

Documentation

README

Excerpt

Instrument — Add Opik Tracing and Verify a Real Trace

Definition of done: a representative, safely-executed path produces a trace that is confirmed in Opik and a direct trace link is returned. If verification can't be completed safely or autonomously, stop at the first genuine blocker and return exactly one concrete next step. Code edits alone are not success.

Operate: opinionated in execution, conservative in code changes, automatic in routine decisions, uncompromising about verifying value — but never by running something unsafe.

Inputs

The entry point is just /opik-instrument (optionally /opik-instrument <path>). Infer everything else; treat these only as optional overrides the user may pass, never as required setup:
