Google Antigravity introduces Boost deep reasoning (/boost)

The /boost slash command launches a three-phase, multi-agent pipeline that breaks complex software problems into discrete subtasks, assigns them to specialized implementation and investigation agents, and iteratively verifies solutions with local builds and full test suites. It is intended for high-intensity tasks such as concurrency bugs, algorithmic optimizations, and multi-file refactorings, delivering a verified code change and concise summary without additional setup.
