Quality

Quality signals

See why the baseline tooling ships by default and which optional tools appear when you opt into deeper testing.

Default quality stack

Purrfold installs the baseline checks by default to catch regressions early and keep feedback close to the code.

React Doctor and React Scan are part of the default stack. Vitest, commitlint, and Playwright only appear when their install choices are selected.
