Detailed overview

Google Jules is an autonomous coding agent that takes on repository tasks and returns completed changes for review. Users select a GitHub repository and branch, write a task prompt (or assign via the 'jules' label on a GitHub issue), and Jules clones the repo to a cloud VM, plans the work using Gemini models, and produces a diff for review before creating a pull request. It performs repository analysis, produces change summaries, and suggests tests, fitting teams that want to delegate well-scoped coding work while keeping human review in the loop before merging.
