What this developer tool does
The validator applies a transparent set of browser-based structural and maintainability rules and calculates syntax-safety, type-safety, consistency, and maintainability scores.
Structural scan → profile rules → weighted violations → category scores → pass/warning/fail result.
Project-wide type resolution and tsconfig behavior require the official TypeScript compiler.
Example
Input:
export function parse(value: any) {
return value;
}Expected use: Run the selected mode and review the generated output and statistics.Tips for better output
- Use Recommended for general application code.
- Strict is useful for public libraries and shared packages.
- Scoring weights are shown in the report.
- Use tsc and ESLint for authoritative project validation.
