retellai-observability

Quick Review

Strong observability skill with comprehensive metrics, tracing, and alerting implementation guidance. The description clearly explains when to invoke the skill for Retell AI monitoring needs. Task knowledge is excellent with concrete code examples for Prometheus metrics, OpenTelemetry tracing, structured logging, and AlertManager rules. Structure is well-organized with clear sections and tables. However, novelty is moderate—while the integration specifics are useful, setting up standard observability patterns (Prometheus + OpenTelemetry + Grafana) is relatively common and could largely be accomplished by a CLI agent with general monitoring knowledge. The skill adds value through Retell AI-specific metric definitions and pre-configured alert thresholds, but doesn't introduce highly complex or unique patterns that would be token-intensive to generate from scratch.
