Google Antigravity has introduced /boost, a slash command that activates an on-demand multi-agent reasoning pipeline for complex software engineering tasks. The feature targets scenarios where standard single-turn coding assistance falls short, including concurrency bugs, race conditions, and intricate refactoring jobs.

Unlike everyday interactive coding workflows, /boost breaks down complex problems, delegates focused workstreams to specialized subagents, and independently verifies solutions across iterative rounds. It sits between rapid interactive development and long-horizon multi-day campaigns, delivering deep reasoning within daily coding sessions.

When invoked, the tool runs a three-phase pipeline. In Phase 1, the Primary Orchestrator inspects workspace context and formulates an execution strategy. Phase 2 dispatches parallel subtasks to subagents handling implementation, investigation, and local verification. Phase 3 aggregates findings, validates against test suites, and loops errors back for automated correction before delivering a verified summary.

According to Hacker News, /boost is available across Antigravity surfaces, including Antigravity 2.0, and sits alongside the Default Agent and Teamwork (/teamwork-preview) modes in the platform's execution tiers.
