zod

Use safeParse instead of parse for Zod schema validation to catch errors gracefully. It returns a structured result object containing success status and error details, letting you handle invalid user input without throwing runtime exceptions.

Use Zod's type inference to automatically derive TypeScript types from your schema definitions. This Skill analyzes your validation code to ensure inferred input and output types stay synchronized with runtime parsing and transformations across your codebase.

The best way to compose nested Zod schemas is to combine primitives, enums, and object modifiers into reusable validation boundaries. This Skill reviews your schema structure to identify composition patterns that prevent duplicate validators and improve maintainability.

Use Zod coercion when you need to transform raw input types like strings into numbers or dates during validation. This Skill evaluates your coercion usage to ensure type transformations are applied safely without breaking inferred TypeScript output shapes.

Extract Zod error messages by flattening the safeParse result and traversing issue paths. This Skill recommends patterns for using flatten and issue paths to generate clear, user-friendly validation feedback for invalid form inputs.

Zod strict object behavior rejects unknown keys that are not defined in the schema. This Skill analyzes your object schema modifiers to verify strictness settings are correctly applied for your validation boundaries and parsing requirements.
