Frequently Asked Questions About Đức Cương
FAQPage SchemaWhat tasks can I accomplish with DucCuong159's skill registry?▼
You can optimize React and Next.js performance, manage state with Zustand, Redux Toolkit, and TanStack Query, design and tune PostgreSQL/MongoDB schemas, run k6 load tests, generate OpenAPI specs and Vitest tests, perform OWASP security assessments, and deploy to Vercel with Docker and GitHub Actions.
Who is the target audience for these skills?▼
Frontend and full-stack engineers working in TypeScript/JavaScript stacks, particularly React and Next.js developers, plus Node.js backend engineers handling PostgreSQL, MongoDB, Redis queues, WebSockets, JWT authentication, and CI/CD deployment pipelines.
How are these skills installed and run?▼
Skills are loaded as SKILL.md files into compatible agent environments; some require manual setup, such as running npm run setup for the Playwright skill to install Chromium, or pinning a reviewed commit before cloning the sql-sentinel analyzer.
Are these skills open source and what licenses apply?▼
Most skills are community-sourced under MIT licenses (e.g., LambdaTest, addyosmani, and stareezy-1 repositories) or Apache 2.0 (vibeship-spawner-skills), making them free to use; several personal or community skills carry no explicit license declaration.
What prerequisites do these skills assume?▼
A Node.js/TypeScript environment is the baseline, with specific skills requiring Playwright and Chromium, Docker and Docker Compose, Redis for BullMQ queues, PostgreSQL or MongoDB instances, and GitHub Actions runners for Lighthouse CI and deployment pipeline templates.
