Can I customize the test coverage threshold?

Yes, when using the --vitest flag, you can specify a custom coverage percentage (e.g., 90%) using the --coverage argument.

Can I use this with npm or Yarn?

This skill is specifically optimized for the Bun package manager to ensure maximum performance and modern dependency management.

Why does it default to Biome instead of ESLint?

Biome is significantly faster than ESLint and Prettier because it is written in Rust, and it simplifies your toolchain by providing linting and formatting in a single tool.

Does this skill support TypeScript?

Yes, it automatically detects and configures TypeScript settings for both Biome and legacy ESLint setups, including appropriate parsers and plugins.

Does it work with VS Code and Cursor?

Yes, it automatically generates a .vscode/settings.json file to enable features like format-on-save and automatic import organization for both Biome and Prettier.
