Implement robust input validation with server-side checks, client-side UX feedback, specific error messages, allowlist strategies, and consistent validation across all entry points. Use this skill when validating user input in web forms, API endpoints, or background jobs; when implementing server-side validation for security and data integrity; when adding client-side validation for immediate user feedback; when validating data types, formats, ranges, and required fields; when providing clear, field-specific error messages; when implementing allowlist strategies instead of blocklists; when sanitizing user input to prevent injection attacks (SQL, XSS, command injection); when validating business rules at the appropriate application layer; when applying validation consistently across web forms, API endpoints, and background jobs; or when designing validation architecture for security and user experience.
