Containers

Generate production-ready Docker configurations for .NET APIs with multi-stage builds, Alpine optimization, layer caching, and build scripts. Use when containerizing .NET applications, creating Dockerfiles, or optimizing existing Docker setups.

Master Kubernetes for managing containerized applications at scale.

WordPress Playground for instant browser-based WordPress testing. Use for quick demos, plugin testing, or ephemeral development environments without Docker.

Master Kubernetes cluster administration, from initial setup through production management. Learn cluster installation, scaling, upgrades, and HA strategies.

Generates entrypoint.sh script for Docker container runtime environment variable injection. Replaces placeholder values in built assets with actual environment variables at container startup.

Docker containerization for packaging applications with dependencies into isolated, portable units ensuring consistency across development, testing, and production environments.

Meta-agent that analyzes tasks and recommends optimal skill combinations with Feynman-style explanations. USE WHEN feeling overwhelmed by 51+ skills, uncertain which skills to apply, need guidance on skill orchestration, or want to understand skill synergies. This is a READ-ONLY analyzer - recommends but never modifies code.

Use when exploring Context level impact during scoping - system boundaries, actors, cross-container interactions, and high-level concerns

Review Dockerfiles for best practices, security, and optimization. Use when the user says "review Dockerfile", "optimize image", "Dockerfile best practices", "reduce image size", or asks to audit a container build.

System 테스트 작성 및 실행. pytest 기반, docker-compose.acceptance.yml 필수, 4단계 순서(infra→component→integration→scenarios). 네이밍 test_{대상}_{시나리오}_{예상결과}. poetry run pytest system-tests/ 실행. Fail Fast - 모든 응답 필드/타입/에러 엄격 검증, 예상외 필드/부작용은 실패 처리.

Troubleshoot and manage Kubernetes clusters, including resource inspection, debugging, pod logs, events, and cluster operations. Use when the user needs to diagnose issues, inspect workloads, analyze pod failures, or perform Kubernetes cluster operations.

Docker Compose 설정 문법 및 구성 검증. Use when (1) compose 검증, (2) config 확인, (3) compose 수정 후.

Scaffold API mocking infrastructure using Mountebank and Testcontainers for reliable integration testing.

This skill should be used when the user asks to "create a machine class", "configure Proxmox provider", "debug provider registration", "set up CEL storage selectors", "troubleshoot Omni provider", "check provider status", "create a Talos cluster", or needs guidance on Omni + Proxmox infrastructure integration for Talos Kubernetes clusters.

Implement idiomatic Kubernetes operations with label selectors, strategic merge patches, and proper error handling for production-grade CLI tooling.

Chrome debugging and inspection via local CDP Docker container

Docker and Docker Compose configuration and troubleshooting. Use for containers, services, volumes, networking, health checks, and deployment patterns.

WSL2 Ubuntu administration from Linux side. Profile-aware - reads preferences fromWindows-side profile at /mnt/c/Users/{WIN_USER}/.admin/profiles/{hostname}.jsonUse when: Inside WSL for apt packages, Docker, Python/uv, shell configs, systemd.Coordinates with admin-windows via shared profile ON THE WINDOWS SIDE.

Generate production-ready Helm charts for Kubernetes apps. Use when: (1) Deploying applications to Kubernetes, (2) Containerizing apps for Minikube/K8s, (3) Creating reusable deployment packages, (4) Needing parameterized K8s manifests, (5) Scaffolding new chart structures. Includes security contexts, resource limits, RBAC, NetworkPolicies, and multi-environment support (dev/prod). Provides templates for frontend, backend, and MCP server components.

Generate and manage Kubernetes manifests including deployments, services, and ingress. Use when deploying applications to Kubernetes or managing k8s resources.
