TypeScript/JavaScript Development Skill

Autonomous Development Workflow

Do not attempt to read or edit files outside the project folder
Add failing tests first, then fix them
Work autonomously in small, testable increments
Run targeted tests, and lint continuously during development
Prioritize understanding existing patterns before implementing
Don't commit changes, leave it for the user to review and make commits

Linting and Formatting

Lint:
```
yarn lint-eslint-pure
```
- Run ESLint on the codebase
Format:
```
yarn prettier
```
- Format code using Prettier
Type Check:
```
yarn type-check-pure
```
- Run TypeScript type checking
