+Title: Spectre1010
+Description: Favor the use of the instance of AnsiConsole over the static helper
+Category: Usage
+Severity: Info
+---
+
+## Cause
+
+A violation of this rule occurs when the static helper `AnsiConsole` is used when a field or method parameter of type
+`IAnsiConsole` is available.
+
+## Reason for rule
+
+Use of `IAnsiConsole` improves testability of the code, and also allows upstream callers the ability to customize the console
+capabilities and features. When a field variable or parameter is available it should be used to ensure the code takes advantage
+of that configuration.
+
+## How to fix violations
+
+To fix a violation of this rule, change from `AnsiConsole` to the name of the local instance.
+
+## Examples
+
+### Violates
+
+```csharp
+class Example
+{
+    private IAnsiConsole _ansiConsole;
+
+    public Example(IAnsiConsole ansiConsole) 
+    {
+        _ansiConsole = ansiConsole;
+    }
+
+    public Run()
+    {
+        AnsiConsole.WriteLine("Running...");
+    }
+
+}
+```
+
+### Does not violate
+
+```csharp
+class Example
+{
+    private IAnsiConsole _ansiConsole;
+
+    public Example(IAnsiConsole ansiConsole) 
+    {
+        _ansiConsole = ansiConsole;
+    }
+
+    public Run()
+    {
+        _ansiConsole.WriteLine("Running...");
+    }
+
+}
+```
