Observability Skill

The three pillars of production visibility: Logs (what happened), Metrics (how often / how fast), Traces (why was this request slow). Without observability, production is a black box.

When to Activate

• Setting up a new service for production
• Debugging production issues without enough information
• Adding monitoring or alerting to an existing service
• Implementing health checks (readiness/liveness probes)
• Setting up error tracking (Sentry, Honeybadger)
• Integrating OpenTelemetry tracing
• Adding structured logging to replace printf-style logs
