How do I check whether this affects my code?

Confirm the affected operation and field in the repository commit you authorize. Inspect supported SDK and HTTP call-site matches, review dynamic or unmatched patterns, and choose the intended application behavior before approving a proposal. Schema validation, type checks, configured runtime checks, and your CI provide different evidence.
