SKILL.md (original)

Review the instructions the agent will receive before you install.

RulCode Development

Build and extend the RulCode platform — a React/Vite/TypeScript application for technical interview preparation covering DSA, system design, and frontend concepts.

Workflow

1. Understand the request

Identify which area of the platform the change targets:

  • Algorithm problems: Adding or editing problems in src/ covering arrays, strings, hashing, two pointers, sliding window, recursion, backtracking, trees, graphs, dynamic programming, and greedy algorithms
  • Visualizations: Step-by-step algorithm animations (see .agents/skills/visualization/SKILL.md)
  • UI components: React components using Tailwind CSS and shadcn/ui (components.json)
  • Backend/data: Supabase integration in supabase/

2. Set up the development environment

npm install
npm run dev

The project uses Vite (vite.config.ts) with TypeScript (tsconfig.json) and Tailwind CSS (tailwind.config.ts).

3. Implement the change

  • Follow existing patterns in src/ for component structure and naming
  • Use TypeScript strict mode conventions from tsconfig.app.json
  • Lint with ESLint (eslint.config.js)
  • Problems support multiple difficulty levels and multiple language implementations

4. Verify

npm run build
npm run lint

Check that the dev server renders the change correctly at the target route.
