lint-and-validate

Use the lint_runner.py script with the project path as argument. It detects package.json, runs npm run lint or npx eslint, then runs npx tsc --noEmit, and outputs a combined pass/fail JSON summary.

Run type_coverage.py against the project directory. It scans Python files, counts functions with and without type hints, measures Any usage, and reports a coverage percentage with pass or fail status.

Yes, the script handles Windows by appending .cmd to npm and npx commands, enabling shell mode for path resolution, and reconfiguring console output to UTF-8 encoding.

The runner uses Ruff for fast linting and style fixes, MyPy for static type checking, and Bandit for security issue detection. It detects Python projects via pyproject.toml or requirements.txt.

This happens when the project lacks package.json, pyproject.toml, or requirements.txt, so no ecosystem is detected. Add the appropriate config file or install ESLint, Ruff, or MyPy to enable checks.

Coverage below 50 percent for TypeScript or 40 percent for Python triggers a critical issue, as does excessive any or Any usage. Critical issues cause the script to exit with code 1.
