SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill introduces compile-time code generation using Roslyn Incremental Generators to reduce boilerplate, improve build times, and enable safer, more maintainable code.

Core Features & Use Cases

Incremental Pipeline: Build reliable generators that cache and reuse results for faster builds.
Semantic Analysis: Leverage Roslyn's semantic model without runtime overhead.
Marker Attributes & DI: Create marker attributes and dependency-injection-friendly patterns for generators.
Diagnostics & Troubleshooting: Emit diagnostics and diagnose performance issues in generators.

Quick Start

Create a generator project implementing IIncrementalGenerator and hook into ForAttributeWithMetadataName.
Define a marker attribute, then generate code for annotated types.
Consume the generated code in a consumer project and build.
