What problem does it solve?
Type assertions on external or unvalidated data bypass runtime checks, risking unsafe type assumptions. This Skill clarifies the safe vs unsafe use of type assertions and advocates validation when data originates outside your control.
Core Features & Use Cases
- Distinguish between Type Guard and Type Assertion.
- Use runtime validation (e.g., schema parsing) before applying assertions to external data.
- Safer patterns for parsing JSON, API responses, and user input.
Quick Start
Validate external input with a type guard or schema before asserting its type; avoid blind casting and rely on explicit validation.
