Data Pipeline CLI Extension

Build a command-line tool that extends a data pipeline framework with custom commands for managing pipeline metadata and generating reports.

Capabilities

Plugin Registration

Register a custom command that can be invoked from the command line. The command should be automatically discovered and available when the tool is installed.

• Installing the package makes a metadata command available that can be invoked from the CLI @test

Metadata Display Command

Implement a command that displays metadata about available pipelines in the project.

• Running metadata list displays a formatted list of all registered pipelines with their names @test
• Running metadata list --format json outputs pipeline information in JSON format @test

Pipeline Statistics Command

Implement a command that shows statistics about a specific pipeline.

• Running metadata stats <pipeline_name> displays the number of nodes, inputs, and outputs for the specified pipeline @test
