All four quality commands exit non-zero on findings, so they drop straight into CI and pre-commit hooks.

Type-check via tsc over the generated shadow config. 
meow check
meow check src/ lib/api.ts

​
meow lint

meow lint
meow lint src/

[paths…]Files/dirs to lint. Defaults to the project root.
Rule severities come from lint.rules in meow.config.json. See Linting.

​
meow fmt

meow fmt --check          # CI mode: report, don't write, fail if any change
Flag / ArgumentDescription
