Google Antigravity introduces /boost for deep reasoning in software engineering tasks

Introducing /boost for Complex Software Tasks

Google Antigravity has introduced /boost, a new slash command designed to activate an on-demand multi-agent reasoning pipeline. This tool targets challenging software engineering tasks that go beyond the capabilities of standard single-turn coding assistance, such as complex bugs, race conditions, and intricate refactoring.

Addressing the Middle Ground of Development Complexity

Modern software development encompasses a range of complexities, from everyday coding to long-horizon campaigns. /boost specifically addresses the interactive, high-intensity developer productivity needs for deep reasoning tasks like high-difficulty concurrency bugs, algorithmic optimization, and multi-file architecture puzzles. It integrates multi-agent deep reasoning directly into coding sessions without requiring extensive setup.

Three-Phase Multi-Agent Reasoning Pipeline

When invoked, /boost initiates a three-phase multi-agent reasoning pipeline. The Primary Orchestrator first receives the prompt, analyzes the workspace context, and formulates an execution strategy. It then breaks down complex challenges into discrete, verifiable subtasks and identifies the necessary specialized workstreams.

Parallel Execution and Verification by Subagents

In the second phase, the Orchestrator dispatches focused subtasks to specialized subagents operating in isolated scopes. These subagents perform implementation workstreams, such as constructing code solutions and generating unit tests, and investigation workstreams, including root-cause debugging and dependency analysis. Subagents also conduct local verification by executing build targets and test suites to validate hypotheses before reporting results. The pipeline aggregates findings and runs regression checks before presenting the final outcome.
