Ln 774 Healthcheck Setup

What it does

This skill, Ln 774 Healthcheck Setup, automates the configuration of health check endpoints for Kubernetes probes and monitoring. It analyzes a project's dependencies (like databases or message queues) to define appropriate health checks and generates the necessary configurations for both .NET (.AspNetCore.Diagnostics.HealthChecks) and Python (FastAPI routes) applications. The goal is to quickly establish baseline monitoring by automatically setting up live, ready, and startup probes.

When to use it

• When deploying a new application to Kubernetes and needing to configure health checks.
• To ensure consistent health check implementation across multiple .NET or Python projects.
• For automating the initial setup of health check endpoints, reducing manual configuration effort.
• When integrating with existing monitoring systems that rely on Kubernetes probes.

Key capabilities

• Dependency Detection: Identifies dependencies like PostgreSQL, MySQL, Redis, RabbitMQ, and MongoDB based on project files (csproj for .NET, requirements for Python).
• Health Endpoint Definition: Defines three types of health endpoints: live, ready, and startup, following Kubernetes best practices.
• Kubernetes Probe Configuration: Generates configurations for Kubernetes probes including initialDelaySeconds, periodSeconds, timeoutSeconds, failureThreshold, and successThreshold.
• .NET & Python Support: Provides configuration guidance and implementation examples for both .NET (using ASP.NET Core health checks) and Python (using FastAPI).
• MCP Integration: Leverages MCP tools and documentation for current best practices in health check implementations.

Example prompts

• "Configure healthchecks for my .NET project."
• "Set up Kubernetes probes for a Python application with PostgreSQL dependency."
• "Generate the initial configuration for health checks, assuming Redis is a dependency."

Tips & gotchas

• Prerequisites: Requires a Context Store from ln-770 and access to the project's root directory (PROJECT_ROOT).
• Idempotency Check: The skill will skip execution if health check configurations are already present (indicated by specific grep patterns).
• Stack Requirement: The skill requires either a .NET or Python stack to be defined.
