Compare two sessions

Goal: put two receipts next to each other and see the ratio between them — which run cost more, and by how much.

aireceipts compare "email format" "intermittently"

Each argument is a selector — an index, a session id, or a title substring. aireceipts prints both receipts, then a one-line ratio:

Add email format validation to the signup form and add a unit test for it. The signup form is in src/components/SignupF… cost 1.9× Can you fix the flaky login test in src/auth/login.test.ts? It's failing intermittently in CI. ($0.18 vs $0.09)

The closing line is the whole point: the first session cost 1.9× the second ($0.18 vs $0.09). Note the second receipt also surfaces a ⚠ Bash loop ×5 waste line — comparison is often how a cheaper-looking run turns out to have burned its budget in a loop.

On a wide terminal the two receipts render side by side; on a narrow one they stack, as above. Either way the numbers are identical.
