This Skill prevents software failures, security vulnerabilities, and data corruption by ensuring all external inputs are thoroughly validated before processing.
Use the Validating Inputs skill to check if this function properly validates all external parameters and handles edge cases.

Validate all external inputs—user data, API responses, database results, and file contents—by checking format, type, range, and length before processing. Apply explicit error handling and safe defaults across your codebase to block invalid data from corrupting downstream logic.
Use two-level defense: assertions for internal invariants to catch logic errors, and structured error handling for external data to ensure deterministic behavior. This approach prevents failures while maintaining data integrity under edge cases.
Review whether the function validates every external parameter for type, range, format, and security constraints, handles edge cases explicitly, and returns safe defaults or clear errors when validation fails.
Validate all data crossing system boundaries—user input, network payloads, database results, and file contents. Use assertions for values generated internally by your own code, which you control directly.
Combine validation rules at entry points with structured exception paths that reject malformed data early. Assert preconditions on internal function inputs and implement format and range checks before any downstream processing occurs.
