Google Antigravity guide splits tasks into fast lanes

The smart take here is that agentic IDEs stop being useful when every task lives in one sprawling thread; context isolation is the real feature, not just more agents. Antigravity's editor/manager split makes that workflow feel intentional rather than bolted on.

• –Planning lanes should absorb architecture, task decomposition, and model choice so execution stays simple.
• –Fast lanes make sense for implementation, verification, and cleanup, especially when agents can hand back artifacts instead of raw logs.
• –Multi-model support only matters if teams match model strengths to the job: reasoning for planning, speed for routine edits, heavier models for tricky refactors.
• –Community feedback is mixed but revealing: reviewers praise planning, walkthroughs, and parallel work, while UI bugs, onboarding friction, and quota limits still get in the way.
