type-safety SKILL.md skillA
type-safety from jnpiyush/agentx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jnpiyush/agentx/type-safety@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:0682abd120fcb64dThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
