Why prspec

Not a code review.
A test review.

the bug isn't in the code review. it's in the test review.

Missing tests

Finds the code paths nobody wrote a test for.

Risky Rails changes

Surfaces migrations, callbacks, and ActiveRecord patterns known to break in production.

Local-first

Runs on a local model by default. Your code doesn't have to leave your machine.
