Frequently Asked Questions About Khoi Nguyen
FAQPage SchemaWhat tasks can I accomplish with dev-khoi's skills?▼
You can structure TypeScript types with generics and satisfies, optimize React hooks usage, configure Tailwind CSS v4, add Auth0 authentication, apply UX psychology frameworks like Hick's Law and Fogg B=MAP, run PDCA/Kaizen improvement cycles, and automate browsers or Electron apps via agent-browser.
Who should use this skill registry?▼
Frontend engineers working in React, Next.js, and TypeScript codebases, plus product managers and UX designers applying structured frameworks like Jobs-to-be-Done, Business Model Canvas, Five Whys root cause analysis, and cognitive bias audits for conversion optimization.
How do the browser automation skills run in practice?▼
The agent-browser, slack, electron, and dogfood skills execute via Bash commands (npx agent-browser), driving headless Chrome or connecting through Chrome DevTools Protocol. The vercel-sandbox skill launches Chrome inside Vercel microVMs for persistent, isolated browser sessions.
Are these skills open source and what do they cost?▼
The Auth0 skills (auth0-react, auth0-quickstart) are explicitly licensed Apache-2.0 by Auth0. Other skills in the manifest carry no stated license or fee; they are prompt-based methodology guides with no runtime cost beyond the host environment.
What prerequisites or dependencies are required?▼
auth0-quickstart requires the Auth0 CLI installed via Homebrew on macOS or Linux. Browser automation skills require npx agent-browser availability. Frontend skills assume existing React, Next.js, TypeScript, or Tailwind v4 projects; methodology skills have no technical dependencies.
