# Refactor and enhance prompt handling logic and tests, update Kotest
version and modularize `AbstractTransport`
- Added more post-conditions/scenarios to ServerPromptsTest
- Extracted `AbstractTransport` to a dedicated file for modularity.
- Improved Protocol connection state validation: When disconnected, the
Protocol will throw `IllegalStateException` instead of `Error`.
- Minor Kotlin fixes and suppressions to improve code quality.
