opik — Open-source LLM Observability, Evaluation & Optimization

Opik (built by Comet) streamlines the entire LLM application lifecycle: deep tracing of LLM calls and agent activity, LLM-as-a-judge evaluation, experiment management, production monitoring at scale (40M+ traces/day), plus the Opik Agent Optimizer and Opik Guardrails. This skill is the routing-first wrapper — it picks the right deployment mode, wires the SDK, and drives the trace → evaluate → monitor → optimize loop.
