+export function getRunSlashCommandDescription(): string {

+Description: Execute a slash command to get specific instructions or content. Slash commands are predefined templates that provide detailed guidance for common tasks. Commands can be built-in, defined globally, or project-specific.
+
+Parameters:
+- command: (required) The name of the slash command to execute (e.g., "init", "test", "deploy")
+- args: (optional) Additional arguments or context to pass to the command
+
+Usage:
+<run_slash_command>
+<command>command_name</command>
+<args>optional arguments</args>
+</run_slash_command>
+
+Examples:
+
+1. Running the init command to analyze a codebase:
+<run_slash_command>
+<command>init</command>
+</run_slash_command>
+
+2. Running a command with additional context:
+<run_slash_command>
+<command>test</command>
+<args>focus on integration tests</args>
+</run_slash_command>
+
+Note: Available commands depend on the project and global configuration. The tool will list available commands if an invalid command is specified. Commands can be:
+- Built-in: Predefined commands like "init" for codebase analysis
+- Global: Custom commands defined in ~/.roo/commands/
+- Project: Project-specific commands defined in .roo/commands/
+
+The command content will be returned for you to execute or follow as instructions.`
