Based on SOC occupation classification
Create a new implementation plan file for new features, refactoring existing code or upgrading packages, design, architecture or infrastructure.
Use when documenting significant technical or architectural decisions that need context, rationale, and consequences recorded. Invoke when choosing between technology options, making infrastructure decisions, establishing standards, migrating systems, or when team needs to understand why a decision was made. Use when user mentions ADR, architecture decision, technical decision record, or decision documentation.
Automatically creates or updates changelogs from git commits by analyzing commit history, categorizing changes and transforming technical commits into clear, customer-friendly release notes. Turns hours of manual changelog writing into minutes of automated generation.
Write modern, high-performance C# code using records, pattern matching, value objects, async/await, Span<T>/Memory<T>, and best-practice API design patterns. Emphasizes functional-style programming with C# 12+ features.
Manage NuGet packages using Central Package Management (CPM), dotnet CLI, and dotnet-outdated (command `dotnet outdated`) to inspect/update dependencies and diagnose restore issues. Never edit XML directly—prefer dotnet commands and dotnet-outdated.
Specialized skill for creating test doubles (Mock, Stub, Spy) using NSubstitute. Use when isolating external dependencies, simulating interface behavior, and verifying method calls. Covers complete guidance on Substitute.For, Returns, Received, Throws, etc.
