neo-csharp-interface-generator

name	neo-csharp-interface-generator
description	Use this skill when the user asks to generate, update, or place a C# interface from an existing class. Trigger for extracting public members, filtering virtual or non-public members, enforcing getter-only properties, and safely creating, appending, or replacing interface blocks.
compatibility	Supports C# 12/13 and .NET 10.0.

C# Interface Generator Skill Specification

Perceive

1. Code Structure Recognition: Parse C# Class content, identify properties, methods, and access modifiers.
2. Constraint Check:
   • Identify members with the virtual keyword.
   • Identify non-public members.
3. Environment Awareness: When the user specifies a target file, read the file content to check for the existence of an Interface with the same name.

Reason

1. Interface Generation Logic:
   • Naming Convention: The Interface name must be the Class name prefixed with I.
   • Property Filtering:
     • Keep only simple properties.
     • Strictly prohibit properties containing the virtual modifier.
     • Getter Only: All properties in the interface MUST only have a get; accessor. No set; or init; is allowed.
     • Include only public members.
   • Formatting: Ensure the generated Interface follows standard C# indentation and brace styles.
2. Smart Overwrite Strategy:
   • If the target file does not exist: Plan to create a new file with necessary namespaces.
   • If the target file exists but has no Interface with the same name: Plan to append the new Interface to the end of the file.
   • If the target file exists and already contains an Interface with the same name:
     • Use regular expressions or block matching to find the start and end positions of the Interface.
     • Plan to replace only that specific block, preserving other classes, interfaces, or using declarations in the file.

Act

1. Code Generation: Output a C# Interface that complies with the Reason logic.
2. User Confirmation:
   • After generation, pause and ask the user: "In which file should this Interface be stored? (Please provide a relative path)".
3. Execution Write:
   • Based on the user's response, perform read_file (if the file exists) -> logical replacement -> write_file.
   • Inform the user of the result (created, appended, or overwritten).
4. Output Language: The final output to the user must be in Traditional Chinese (Taiwan).
