Zod app built with Claude Code? Let’s review it.
Expert code review for Zod apps built with Claude Code. We find Claude Code-specific bugs, fix Zod security issues, and optimize performance. From $19.
Claude Code issues we find in Zod projects
Problems specific to Claude Code's code generation patterns when building Zod apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Edge cases in complex logic
While Claude handles the main flow well, complex conditional logic sometimes has edge cases that produce incorrect results with unusual inputs.
Zod issues we check for
Common Zod problems that affect production readiness.
Incomplete schema validation
Zod schemas that validate the happy path but miss edge cases like empty strings, negative numbers, or overly long inputs that break downstream logic.
Schema-data mismatch
Zod schemas that don't match the actual API response or database shape, causing runtime parse errors that crash the application.
Missing transform and refinement
Schemas that accept raw input without transforming (trimming strings, normalizing emails) or refining (custom business rules), leading to dirty data in the database.
No error message customization
Default Zod error messages exposed directly to users, showing technical details like 'Expected string, received number' instead of user-friendly messages.
