The Jules Extension for Gemini CLI (developers.googleblog.com)

Gemini CLI has a new autonomous extension called Jules that lets developers offload asynchronous coding chores to a background “sidekick.” Jules runs in a VM where it clones your repository, installs dependencies, and edits files, so you can keep working interactively in Gemini CLI while long-running or repetitive tasks execute independently. The extension is part of the growing Gemini CLI ecosystem and is available now on GitHub. Technically, Jules is invoked with the /jules command (e.g., “/jules Convert commonJS modules to ES modules”) and you can query task progress with follow-up /jules prompts like “what is the status of my last task?”. Install requires Gemini CLI v0.4.0+ and is performed with: gemini extensions install https://github.com/gemini-cli-extensions/jules --auto-update (the --auto-update flag is optional). The VM sandboxing and autonomous edit capabilities accelerate refactors, dependency setup, and other background workflows, but also imply you should review automated changes and manage update preferences. Overall, Jules brings asynchronous, automated developer workflows into the terminal, improving productivity for coding, migration, and maintenance tasks.
