Generate production-ready Kubernetes manifests with Deployments, Services, ConfigMaps, and Ingress
npx claudepluginhub joshuarweaver/cascade-code-general-misc-4 --plugin glincker-claude-code-marketplaceThis skill is limited to using the following tools:
Generate complete Kubernetes manifests by analyzing your application. Creates Deployments, Services, ConfigMaps, Secrets, Ingress, and HPA with production best practices.
Generates design tokens/docs from CSS/Tailwind/styled-components codebases, audits visual consistency across 10 dimensions, detects AI slop in UI.
Records polished WebM UI demo videos of web apps using Playwright with cursor overlay, natural pacing, and three-phase scripting. Activates for demo, walkthrough, screen recording, or tutorial requests.
Delivers idiomatic Kotlin patterns for null safety, immutability, sealed classes, coroutines, Flows, extensions, DSL builders, and Gradle DSL. Use when writing, reviewing, refactoring, or designing Kotlin code.
Generate complete Kubernetes manifests by analyzing your application. Creates Deployments, Services, ConfigMaps, Secrets, Ingress, and HPA with production best practices.
Analyze the application to determine requirements:
# Detect application type
Use Glob/Grep to find:
- Dockerfile → Container config
- .env → Environment variables
- Port bindings
- Volume requirements
