Crescendo is a development accelerator enabling you to rapidly build PowerShell cmdlets that leverage existing command-line tools. Crescendo amplifies the command-line experience of the original tool to include object output for the PowerShell pipeline, privilege elevation, and integrated help information. A Crescendo module replaces cumbersome command-line tools with PowerShell cmdlets that are easier to use in automation and packaged to share with team members.

The 1.0.0 release includes the following features and benefits:

• Ability to define cmdlets from simple key/value statements in a JSON file
• Support for modular design - cmdlet definitions can be in a one or more JSON files
• A JSON schema that helps you create your Crescendo configuration using IntelliSense and tooltips
• Three styles of output handling code allowing you to separate your code from the cmdlet definitions for easier debugging and development
• Privilege elevation mechanisms in Windows, Linux, and macOS
• Crescendo generates a PowerShell script module ready for deployment
• While Crescendo requires PowerShell 7 or higher for authoring configurations, the generated module can run on Windows PowerShell 5.1 and higher
• Example configurations for you to copy and reuse
• Experimental Help parsers that provide proof-of-concept examples for auto-generating cmdlet configurations
