Users can now wrap text in asterisks to instruct the AI to perform actions. Input like *you decide to tell a story* is transformed into "You decide to tell a story." before being sent to the AI, allowing users to prompt character behaviors directly.

Implementation

• Added TransformAsteriskActions() method with compiled regex \*([^*]+)\* for pattern matching
• Integrated transformation into ChatAsync() and GenerateRandomDialogAsync()
• Transformation removes asterisks, capitalizes first letter, adds punctuation if missing
• Handles edge cases: single characters, empty strings, multiple actions per message

Example transformations

*you wave* → "You wave."
Hello *you smile* how are you? → "Hello You smile. how are you?"
*a* → "A."

Documentation

• Added user-facing examples to README.md
• Added Pipeline protocol documentation for external integrations

Performance

• Uses RegexOptions.Compiled for frequently-called chat operations
• Optimized with StringBuilder.Append(string, int, int) overloads
