Interfaces: `IInterface`. - 2-space indent, 100-column limit. Braces on same line; always use braces. - One core class per file; filename matches main class (`MyClass.cs`). - Modifier order: public protected internal private new abstract virtual override sealed static readonly extern unsafe volatile async. - `using` directives alphabetical after `System` imports. ## Quick checklist - Match Google C# naming and formatting conventions - Keep code readable; prefer consistency within the file and package - Run language-appropriate linters/formatters when available - Document non-obvious behavior with brief, accurate comments - Defer to the official guide when this skill is silent ## Official guide
