Suitable workflows
Developers using Google accounts, Gemini API keys or Vertex AI.
Limitations and billing

Pricing & usage
Free access; see limits
Account quota or metered Gemini / Vertex AI usage. The cost of metered usage or an external agent can be separate from the subscription.
Models & access
Google sign-in, Gemini API key, or Vertex AI credentials.
Verified families: Gemini.
Install and start the CLI

npm install -g @google/gemini-cliOpen your project folder in a terminal, then run:
geminiAccount and authentication
Choose Google sign-in, GEMINI_API_KEY, or Vertex AI on first launch.
Project configuration and tools
Use GEMINI.md for project context; configure extensions and MCP separately from authentication.
First task to try
Map the main modules and test commands before asking Gemini to change a file.
Script usage
This example asks for a project summary. Tool permissions still apply; a prompt is not a sandbox.
gemini -p "Summarize the project structure without modifying files."Related CLI tools

Project evaluation checklist
- Open a small, familiar project and confirm that your essential language tooling works.
- Give the agent one bounded change with an observable acceptance criterion.
- Review the diff, run the project’s checks and compare the result with your current workflow.
- Inspect usage after the task. Estimate a month of similar work, including any separate model or agent bill.
