Gemini Workspaces: Maintainer Onboarding

Gemini Workspaces allow you to offload heavy tasks (PR reviews, agentic fixes, full builds) to a high-performance GCP worker. It uses a Unified Data Disk architecture to ensure your work persists even if the VM is deleted or recreated.

1. Local Prerequisites

Before starting, ensure you have:

• GCloud CLI: Authenticated (gcloud auth login).
• GitHub CLI: Authenticated (gh auth login).
• Project Access: A GCP Project ID where you have Editor or Compute Admin roles.

2. Initialization

Run the setup script using npx tsx to ensure all dependencies are available:

npx tsx .gemini/skills/workspaces/scripts/setup.ts

What happens during setup:

1. Auth Discovery: It will detect your GEMINI_API_KEY (from ~/.env) and GH_TOKEN.
2. Project Choice: You will be prompted for your GCP Project and Zone.
3. Infrastructure Check: It verifies if your worker (gcli-workspace-<user>) exists.
4. SSH Magic: It generates a local .gemini/workspaces/ssh_config for seamless access.

3. Provisioning

If the setup informs you that the worker was not found, provision it:

npx tsx .gemini/skills/workspaces/scripts/fleet.ts provision

This creates a VM with a 10GB Boot Disk and a 200GB Data Disk. Initialization takes ~1 minute.

4. Finalizing Remote Setup

Run the setup script one last time to clone the repo and sync credentials:

npx tsx .gemini/skills/workspaces/scripts/setup.ts

When you see "ALL SYSTEMS GO!", your workspace is ready.

5. Daily Usage

Once initialized, you can launch tasks directly through npm:

• Review a PR: npm run workspace <PR_NUMBER> review
• Fix a PR: npm run workspace <PR_NUMBER> fix
• Check Status: npx tsx .gemini/skills/workspaces/scripts/status.ts
• Stop Worker: npx tsx .gemini/skills/workspaces/scripts/fleet.ts stop (Recommended when finished to save cost).

Troubleshooting

• Permission Denied (Docker): The orchestrator handles this by using sudo docker internally.
• Dubious Ownership: The system automatically adds /mnt/disks/data/main to Git's safe directory list.
• Missing tsx: Always prefer npx tsx when running scripts manually.
