Every codebase collects small chores, technical debt and maintenance that end up slowing you down. Can you imagine an agent doing that work proactively, without you having to ask every time? Google is betting on proactive agents, and today Jules takes an important step in that direction.
What it means for Jules to be proactive
The goal isn't to replace the reactive model — prompts are still how you direct it — but to expand Jules' role so it thinks one step ahead. A proactive agent doesn't wait for you to report an error: it supervises, proposes fixes, prepares PRs and keeps the system healthy in the background while you focus on complex features and creativity.
Technically, this means combining continuous code scans, scheduled tasks and direct connections to your deployment platform to close the loop between failure and fix.
Real example: Stitch
The team behind Stitch set up a "pod" of Jules agents with daily tasks, each one assigned a specific role: performance tuning, security patches, accessibility improvements and increasing test coverage. The practical result was that Jules became one of the top contributors to the repository, freeing the human team to work on higher-value problems.
