Run Gemini CLI in Agentastic
Google's terminal coding agent, with interactive prompts, plan mode, resume, and unattended runs.
What Agentastic adds
Give every task its own worktree, branch, or container.
Keep Gemini CLI's real CLI and your existing configuration.
Inspect the diff, run code review, test, and open a pull request.
Launch Gemini CLI
- Install the official CLI and sign in with your existing provider account.
- Open a repository in Agentastic. The connection is discovered from your PATH.
- Open Agent Home, choose Gemini CLI, describe the task, and select worktree, local, container, cloud, or remote mode.
Every run gets its own git worktree, so three tasks can share a repository without sharing a branch or a build directory.
What Gemini CLI supports
- Launch from a task description: supported
Type the task in Agent Home and Agentastic hands it to gemini at launch, so the run starts from your prompt instead of an empty session.
- Unattended runs: supported
Gemini CLI can run without stopping for per-tool confirmation, which is what makes an overnight or scheduled run finish on its own.
- Plan before editing: supported
Start Gemini CLI in a read-only pass that proposes an approach without touching the working tree, then approve it and let the same session execute.
- Resume a session: supported
Reopen the last Gemini CLI session for a worktree and keep its history — useful when reviewing the diff turns up one more change.
- Structured chat: not supported
Gemini CLI runs in its own terminal UI inside Agentastic; it does not expose a protocol Agentastic can render as a structured chat.
- Code review: not supported
Gemini CLI writes the change; pair it with a review-capable agent for the pass before merge.
Agentastic reads these from Gemini CLI's own CLI rather than emulating them, and modes it does not support stay out of the picker. The provider reference lists the exact flags for each launch, and how to compare coding agents covers what changes when you switch harnesses.
Gemini CLI questions
Is there a GUI for Gemini CLI?
Yes. Agentastic runs the real Gemini CLI CLI (gemini) in a native Mac workspace with a git worktree, terminal, diff view, and code review for each task.
How do I run multiple Gemini CLI sessions in parallel?
Start each task from Agent Home in worktree mode. Agentastic gives every run its own git worktree and terminal, so several Gemini CLI sessions can work in one repository without editing the same files.
How do I install Gemini CLI?
Run npm install -g @google/gemini-cli, then sign in the way Gemini CLI's documentation describes. Agentastic finds the gemini command on your PATH when you open a repository.
Does Agentastic charge for Gemini CLI?
No. Agentastic is free and does not proxy model calls. It launches Gemini CLI with the credentials and plan you already use, so any usage is billed by your provider, not by Agentastic.
