What problem does it solve?

Misconfigured health check endpoints and Kubernetes probes are a leading cause of cascade failures, rolling deploy outages, and latent production incidents in cloud-native applications. This Skill eliminates these critical defects by enforcing 2026 best practices for health check implementation.

Core Features & Use Cases

• Probe Separation Validation: Ensures liveness, readiness, and startup probes are correctly partitioned to prevent cascade restarts from dependency blips.
• Graceful Shutdown Auditing: Checks for proper preStop hooks and terminationGracePeriodSeconds configuration to avoid 5xx errors during rolling deploys.
• Compliance Enforcement: Validates RFC 9457 compliant response bodies, unauthenticated probe access, and circuit-breaker protected dependency checks.
• Use Case: For a Kubernetes-deployed microservice using a single /health endpoint for both liveness and readiness, use this Skill to identify the cascade-restart risk and get guidance to split into distinct /livez, /readyz, and /startupz endpoints.

Quick Start

Use the health-check-validator skill to audit the health endpoints and Kubernetes probe configuration of your deployed microservice.
