    You say

    Identify why our Stripe adapter sends integers but the checkout service uses floats, then create a patch to use minor units consistently.

    Your agent does

    I found float leakage in checkout_service.ts. I created a patch to: 1. Introduce a Money type. 2. Update the Stripe adapter to map to this type. 3. Add a test case for JPY zero-decimal handling.

    What you get

    Eliminate floating-point math in monetary calculation paths.Align API schemas with database decimal precision.Standardize major and minor unit conversions across services.Implement deterministic rounding and allocation logic.Verify currency exponent handling for international payments.

    About this skill

Detect float leakage, exponent mismatch, double conversion, inconsistent totals, and currency loss; prepare bounded patches and deterministic local tests without live payment APIs, customer charges, policy changes, or production-data migration.
