type-safety skillA
type-safety is agent-read markdown (skill) from jnpiyush/agentx: Apply type safety patterns including nullable types, validation, static analysis, and strong typing. Use when adding type annotations, implementing nullable reference types, validating inputs with value objects, configuring static analysis tools, or designing type-safe APIs..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Type Safety > **Purpose**: Use type systems to catch errors at compile/analysis time rather than runtime. > **Goal**: Prevent null errors, type mismatches, and invalid states. > **Note**: For implementation, see [C# Development](../../languages/csharp/SKILL.md) or [Python Development](../../languages/python/SKILL.md). --- ## When to Use This Skill - Adding type annotations to existing code - Implementing nullable reference types - Building type-safe APIs with value objects - Configuring static analysis tools - Designing strongly-typed data transfer objects ## Prerequisites - Language with type system support ## Decision Tree ``` Type safety concern? +-- Adding types to existing code? | +-- Greenfield? -> Enable strict mode from day one | +-- Legacy codebase? -> Enable strict incrementally (file-by-file) | +-- Third-party input? -> Validate at boundary, trust internally +-- Choosing a type strategy? | +-- Primitive obsession? -> Introduce value objects (Email, Money, UserId) | +-- Magic strings/numbers? -> Replace with enums or constants | +-- Nullable confusion? -> Enable nullable reference types, annotate everything +-- Handling unknown data? …

How to install
mdr add jnpiyush/agentx/type-safety@v1.0.0mdr add jnpiyush/agentx/type-safety@sha256:0682abd120fcb64dPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
