The new Twilio CLI beta offers several features that make it easier for developers to interact with Twilio's services. The CLI allows users to run tasks in their terminal without needing to visit the Twilio console, and it ships with hundreds of commands for navigating and controlling Twilio's services. Auto-completion is enabled by default, making it easy to discover new commands, and the `--help` flag provides information on how to use each command. The CLI also offers configurable output options, allowing users to adjust the format of their output to suit their needs. Additionally, the tool enables piping attachment data into email commands and automatically sets up local webhook URLs for development, making it easier to work with Twilio's services in a local environment. Furthermore, the CLI has a powerful plugin system that allows developers to extend its functionality with new commands and features.
