Gemini CLI: Automate Google Workspace from Your Terminal 2026
Google's Gemini CLI is an official command-line interface for interacting with Gemini 2.5 Pro and Google Workspace APIs directly from the terminal. Released in late 2025 and updated through 2026, the CLI provides a multi-turn chat interface with 1M token context, native tool access to Gmail, Calendar, Drive, Docs, and Sheets, plus code execution and web search capabilities. For developers and technical professionals who live in the terminal, the Gemini CLI eliminates the need to switch between multiple browser tabs and applications.

What You Can Do with Gemini CLI
Email management: 'Summarize my unread emails from this week, identify action items, and draft responses to the urgent ones.' Gemini reads your Gmail inbox, extracts key information from threads, identifies actionable items, drafts personalized responses, and presents them for review. Approve with 'send' and the CLI executes via the Gmail API.
Calendar and scheduling: 'Check my calendar for available slots this week and schedule a 30-minute review meeting with the engineering team.' Gemini queries your Calendar, identifies open slots that work for all invitees, creates the meeting with a generated agenda, and sends invites.
Document automation: 'Read the Q2 strategy doc, summarize key decisions, and create a presentation outline in a new Google Doc.' Gemini accesses the source doc, extracts structured information, creates a new doc with the outline, and shares it with specified collaborators.

Multi-step reasoning is where the CLI shines. A complex request like 'check my calendar for this week, pull the agenda docs for each meeting, analyze the total time spent per project category, and send me a weekly summary' triggers sequential Operations across Calendar, Docs, and Gmail APIs. Each step's output feeds into the next, with Gemini maintaining full context across the chain.
