Google recently launched Jules Tools, a command-line interface (CLI) designed specifically for their AI coding agent, Jules. This new tool allows developers to interact with Jules directly from the terminal, streamlining the process of managing coding tasks such as bug fixes, test writing, and code management without needing to switch to a browser.
Jules Tools is powered by Google’s Gemini model and operates asynchronously, enabling developers to execute instructions with minimal human intervention. The CLI allows for the creation of tasks, session monitoring, and local patch application, integrating seamlessly with existing workflows through scriptable commands. Developers can enjoy features such as repository memory for learning preferences, precise file selection, pull request comment responses, image upload capabilities, and improved diff viewing.
In addition to the CLI, Google also launched the Jules API, which offers developers the ability to create custom agents to automate more complex tasks across the software development lifecycle. This API seamlessly integrates with GitHub repositories, using a REST interface facilitated by simple curl commands. It enables developers to initiate sessions with natural language prompts to streamline tasks like app creation. This API, however, is still in early alpha stage.
Jules Tools aims to enhance the developer experience by integrating into the terminal environment — a place where developers spend a significant amount of their time. It is designed to work with various CI/CD systems and communication tools like Slack. Google is also exploring the extension of support for version control systems beyond GitHub, alongside better mobile notification features.
For those interested in exploring Jules Tools, it can be installed via npm and offers both command-based and interactive text user interface (TUI) modes. Google’s offering starts with a free plan allowing up to 15 daily tasks, with tiered paid plans available at $19.99 and $124.99 monthly, catering to different levels of developer needs. As AI coding agent competition intensifies, Jules Tools positions itself as a robust companion for modern software development practices.
