What is the difference between liveness and readiness probes?

Liveness probes determine if a container is still running and should be restarted if it fails. Readiness probes determine if a container is ready to accept traffic; if it fails, the container is removed from service load balancers.

Can this skill generate Kubernetes YAML configurations?

Yes, it provides optimized YAML snippets for livenessProbe and readinessProbe configurations, including recommended initial delays and failure thresholds.

Does this skill support frameworks other than Express.js?

Yes, while the primary examples use Express, the skill includes patterns and references for Python Flask, Java Spring Boot, and general RESTful implementations.

Why shouldn't liveness checks depend on external services?

If an external dependency like a database goes down, a liveness check that depends on it would cause your application to restart repeatedly, which doesn't fix the database but does create unnecessary downtime.

분석 및 모니터링

Implements robust health check endpoints to monitor service availability, readiness, and dependency health for production environments.

소개

This skill equips Claude with the expertise to implement production-ready health check patterns for web applications and microservices. It provides standardized templates for liveness, readiness, and startup probes, specifically optimized for Kubernetes and cloud load balancers. By automating the creation of these endpoints, the skill ensures that applications handle traffic gracefully, recover from failures through auto-scaling, and provide deep visibility into external dependency status—such as databases and caches—while following industry best practices for timeout and status code management.
