Gemini CLI Full Course: Agentic Coding in the Terminal

Gemini CLI tutorial — moving AI out of the browser tab and into the terminal, where it can actually touch your codebase. Most developers use AI by copying code into a chat window and pasting the answer back, which works until the task spans more than one file. This course covers the alternative: agentic workflows where the model plans, executes, and iterates across multiple steps under your control. Installation and auth, interactive and non-interactive modes, context management and scoping to avoid token bloat, IDE integration, MCP and tooling, then the practical builds — debugging broken code, generating and running tests, refactoring a codebase, writing documentation, and wiring the CLI into CI/CD and team workflows. It closes on the part most tutorials skip: verifying correctness and catching hallucinations before they reach your repo.

Basic programming knowledge required — you should be comfortable in a terminal and with version control. A Google account is needed for authentication; check current free-tier limits before running large jobs against a real codebase.

⚠️ The Gemini CLI moves fast. Commands, flags, and IDE integrations change between releases, so if something in the video doesn't match what you see, check Google's current CLI documentation — the workflow patterns hold even when the syntax shifts.

⚠️ Before you point an agentic workflow at real code: work on a branch, commit before you start, and review every diff. An agent that can refactor across files can also break across files.
