Go-Based Architecture — Built in Go for faster startup and lower resource usage
Multi-Step Reasoning — Plan and execute complex workflows across multiple files and shell commands
Multi-File Editing — Make changes across your entire codebase with natural language
Tool Calling — Execute shell commands, API calls, and file operations within agent workflows
Persistent History — Conversations persist across sessions; no need to re-explain context
Asynchronous Workflows — Background long-running tasks without blocking your terminal
Parallel Subagent Orchestration — Spawn concurrent agents for simultaneous subtasks
New Slash Commands — /goal and /schedule replace manual model selection
Plugin Architecture — Antigravity plugins replace old Extensions system
Shared Agent Harness — Core engine improvements apply to both CLI and desktop app
Free During Preview — No cost during evaluation period

Go-based architecture: faster startup, lower memory than Node.js alternatives
Asynchronous workflows: long-running tasks don't block your terminal
Parallel subagent orchestration: concurrent task execution from the command line
Persistent history: pick up conversations where you left off
Official Gemini CLI replacement: clear migration path with concept parity
Free during preview: zero cost to evaluate
Shared agent harness with Antigravity 2.0: improvements apply to both CLI and desktop
Plugin architecture: maintains extensibility for power users
Multi-file editing, tool calling, and multi-step reasoning in terminal
New slash commands (/goal, /schedule) enable structured autonomous workflows

No 1:1 parity with Gemini CLI Extensions at launch — custom setups need retesting
CLI is narrower than Antigravity 2.0 desktop app — no visual orchestration
Slash command model changed — Gemini CLI muscle memory needs adjustment
Preview pricing means eventual cost structure is unknown
Auto model selection means less explicit control than manual routing
New product with limited production track record at launch
