# .NET Tag Helper Expert Skill ## Trigger On - The user requests to create, generate, or design a custom Razor Tag Helper in C#. - The user wants to encapsulate complex HTML/UI logic into reusable custom tags without using Partial Views or CSHTML. - The target framework is .NET 6.0 (LTS) and above. ## Workflow (Generator Pattern) Follow these steps exactly to create robust, high-performance C# Tag Helpers. ### Step 1: Perceive & Gather Requirements (Inversion) Before writing any code, ask the user to clarify the following if not already provided: 1. **Target HTML Tag**: What is the name of the custom tag in HTML? (e.g., `<my-button>`, `<user-card>`) 2. **Properties**: What parameters/attributes should this tag accept? (e.g., `theme`, `is-active`, `user-id`) 3. **Dependencies (DI)**: Does this tag need to query a database or call a service? (Needs Dependency Injection) 4. **Context**: Does it need to access `ViewContext` (e.g., to generate URLs or check model state)? ### Step 2: Reason & Design (Planning) Based on the answers: - **Class Naming**: Ensure the class name ends with `TagHelper` (e.g., `MyButtonTagHelper`). - **Target Element**: Apply `[HtmlTargetElement("my-button")]`. - **Properties**: Map HTML kebab-case attributes to C# PascalCase properties. Apply `[HtmlAttributeName("is-active")]` if necessary. - **Method Selection**: - If no IO/Async operations, override `Process`. - If using DI for database/API calls, override `ProcessAsync`. ### Step 3: Act (Code
