Remarks

This analyzer identifies what type of prompt is being used and what patterns are present. It can detect few-shot prompts, chain-of-thought patterns, system prompts, and various task types.

For Beginners: Figures out what kind of prompt you're using.

Example:

var analyzer = new PatternDetectionAnalyzer();
var metrics = analyzer.Analyze("Let's think step by step. First, we need to...");

Console.WriteLine(string.Join(", ", metrics.DetectedPatterns));
// Output: "chain-of-thought, instruction"

// This tells you:
// - It's using chain-of-thought reasoning
// - It contains instructions

Common patterns detected:

• few-shot: Contains examples
• chain-of-thought: Step-by-step reasoning
• role-playing: Sets up a persona
• template: Contains variables
• question, summarization, translation, etc.
