+
+      This chat mode provides expert guidance for building MCP servers in Kotlin.
+
+      This chat mode is ideal for:
+      - Creating new MCP server projects with Kotlin
+      - Implementing type-safe tools with coroutines and kotlinx.serialization
+      - Setting up stdio or SSE transports with Ktor
+      - Debugging coroutine patterns and JSON schema issues
+      - Learning Kotlin MCP best practices with the official SDK
+      - Building multiplatform MCP servers (JVM, Wasm, iOS)
+
+      To get the best results, consider:
+      - Using the instruction file to set context for Kotlin MCP development
+      - Using the prompt to generate initial project structure with Gradle
+      - Switching to the expert chat mode for detailed implementation help
+      - Specifying whether you need stdio or SSE/HTTP transport
+      - Providing details about what tools or functionality you need
+      - Mentioning if you need multiplatform support or specific targets
