What is Jules by Google?

Turn labeled issues into auditable PRs with an agent that plans edits tests and explains every step

Jules is an experimental coding agent from Google designed to handle scoped engineering tasks with human oversight. You label a GitHub issue or call the CLI then Jules fetches your repository to a secure Google cloud VM. It drafts a concrete implementation plan using the latest Gemini models shows the exact files it will touch and asks for approval. When you confirm it edits code runs dependency install and tests and validates the result against your acceptance criteria. The agent then opens a pull request with a summary of decisions and links to diffs so reviewers move faster. Because Jules lives close to your repo and CI you avoid heavy local setup. Teams use it for framework upgrades mechanical refactors dependency bumps documentation fixes and small features that are well specified. For critical changes you stay in the loop confirm steps and enforce code owners. Early access materials emphasize auditability safety rails and repeatable workflows rather than black box magic which makes it attractive for production teams that need rigor with speed.
