10 Claude Prompts for Faster Code Reviews (With Examples)

5. Does This Change Break Backward Compatibility?

Prompt: Analyze this diff for backward compatibility issues. Check for:

• Removed or renamed public API methods.
• Changed function signatures.
• Modified database schema without migration.
• Changed JSON field names in request/response bodies.
• Changed environment variable names.
• Altered default behavior.

List each breaking change with its severity (breaking vs. deprecation-worthy) and a migration path.

11Three things changed:
12- Method name
13- Param type name
14- Return type name
15
16Migration Path:
171. Update all client-side code to use `addUser` instead of `createUser`.
182. Ensure that the new parameter type (`CreateUserParams`) is used in place of `UserParams`.
193. Adjust any downstream logic expecting a `Promise<User>` return value to handle `Promise<UserRecord>`.
