Terraform IaC設計 - モジュール設計、状態管理、セキュリティベストプラクティス

Token-efficient retrieval using depth levels (L0-L5) and heading-based sections. Use for any file reads.

This skill should be used when the user mentions "context is full", "running slow", "session performance", "memory optimization", "context pruning", "session health", "optimize session", "long session", or when noticing degraded response quality. Provides guidance for efficient context management during extended coding sessions.

Write and maintain CSS following project conventions using consistent methodologies like Tailwind CSS, BEM, CSS modules, or utility classes, while creating distinctive, aesthetically excellent designs. Use this skill when writing CSS styles, applying Tailwind utility classes, creating custom CSS, working with styling files (*.css, *.scss, *.module.css, globals.css, tailwind.config.*), maintaining design systems and design tokens, defining CSS variables for colors and spacing, implementing typography styles with unique font choices, creating atmospheric backgrounds and depth, adding animations and micro-interactions, avoiding framework style overrides, avoiding generic "AI slop" aesthetics (purple gradients, Inter/Roboto everywhere, cookie-cutter designs), optimizing CSS for production with purging and tree-shaking, or ensuring consistent styling patterns across the application. Apply this skill when styling components, refactoring CSS code, setting up design systems, choosing fonts and colors, creating animations, or reviewing styling approaches for consistency, maintainability, and aesthetic excellence.

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

Scaffold a new Ansible role via ansible-galaxy init

This skill should be used when implementing Supabase email/password authentication in Next.js applications. Automates the complete setup including client/server utilities, login/register pages, auth callback handling, middleware protection, and email configuration. Handles common errors like PKCE flow issues, cookie management, and admin role verification.

Structured telemetry library for Clojure/Script. Use when working with logging, tracing, structured logging, events, signal handling, observability, or replacing Timbre/tools.logging.

Enhanced Just-In-Time document loading system that intelligently discovers, loads, and caches relevant documentation based on user intent and project context. Use when users need specific documentation, when working with new technologies, when answering domain-specific questions, or when context indicates documentation gaps.

Create multi-stage Azure Pipelines with deployment gates and approvals. Use when implementing complex deployment pipelines with multiple environments.

Use this skill when the user asks about Rust module dependencies, dependency graphs, architecture visualization, cycle detection, DAG analysis, or module structure. Activate when you see phrases like "show module structure", "dependency graph", "visualize architecture", "check for circular dependencies", or "Mermaid diagram of modules".

Create best-in-class repository scaffolds with modern tooling, security, CI/CD, testing, and documentation. Works for code, data science, ontologies, APIs, and CLI projects.

WSL2 Ubuntu administration from Linux side. Profile-aware - reads preferences from Windows-side profile at /mnt/c/Users/{WIN_USER}/.admin/profiles/{hostname}.json Use 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.

Master end-to-end testing with Playwright to build reliable test suites that catch bugs, improve confidence, and enable fast deployment. Use when implementing E2E tests, debugging flaky tests, or establishing testing standards.

Analyze and optimize markdown documents for size, structure, and maintainability. Use when: (1) markdown files are too large or verbose, (2) documentation needs restructuring, (3) checking docs for quality issues, (4) converting prose to tables.

Validate Dapr component configs, sidecar annotations, and mTLS settings. Use when: (1) Creating Dapr Component manifests, (2) Adding Dapr annotations to deployments, (3) Configuring pub/sub, state stores, or bindings, (4) Before deploying Dapr-enabled applications, (5) Generating new Dapr components. Validates secrets management (secretKeyRef), scopes, mTLS, sidecar resource limits, and namespace configuration.

Master design patterns and SOLID principles. Learn creational, structural, behavioral patterns, and their real-world applications.

Build execution philosophy including TDD discipline, Minimal Intervention Principle, system awareness, and verification protocols. Use when implementing code, managing build phase, enforcing test-first practices, or preventing accumulative complexity. Triggers on: build phase, TDD, test first, red green refactor, minimal code, system awareness, implementation, code quality, verification protocols, build philosophy.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
