OpenCode Antigravity Multi-Account Setup Package

Automated, portable setup package for OpenCode with the Antigravity OAuth plugin (opencode-antigravity-auth), pre-configured multi-account rotation, and Gemini 3.7 Flash as default.

What's Included

Full Model Definitions (opencode.json & opencode.jsonc):
- google/antigravity-gemini-3.7-flash (Default fast model)
- google/antigravity-gemini-3.1-pro (Reasoning / Pro model)
- google/antigravity-claude-sonnet-4-6 (Claude Sonnet)
- google/antigravity-claude-opus-4-6-thinking (Claude Opus with extended thinking)
Multi-Account Auto-Rotation (antigravity.json):
- Configured with hybrid account selection strategy and balance scheduling mode.
- Automatically switches accounts when rate limits (429) or quota exhaustion occurs.
Saved Google Accounts (antigravity-accounts.json):
- Pre-authenticated and verified Google accounts ready for immediate use.
Automated Compatibility Patch (scripts/patch-plugin.py):
- Patches opencode-antigravity-auth to seamlessly route gemini-3.7 requests to the Antigravity backend API.
One-Click Installers (install.sh for Linux/macOS/WSL, install.ps1 for Windows PowerShell).

Quick Start (Automated Installation)

Linux / macOS / WSL

Extract the archive:

bash
1tar -xzf opencode-antigravity-setup.tar.gz 2cd opencode-antigravity-package
Run the installer:

bash install.sh
Verify and start using:

bash
1opencode run "Say hello from Gemini 3.7 Flash!" 2opencode

Windows (PowerShell)

Extract the archive:

powershell
1tar -xzf opencode-antigravity-setup.tar.gz 2cd opencode-antigravity-package
Run the installer script:

powershell
1Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass 2.\install.ps1
Verify:

opencode run "Say hello from Gemini 3.7 Flash!"

Manual Installation (Step-by-Step)

If you prefer to manually place the files without running the installer:

Copy configuration files to ~/.config/opencode/:

bash
1mkdir -p ~/.config/opencode 2cp -r config/* ~/.config/opencode/ 3chmod 600 ~/.config/opencode/antigravity-accounts.json
Copy cache packages (optional, speeds up first load):

bash
1mkdir -p ~/.cache/opencode/packages 2cp -r cache/packages/* ~/.cache/opencode/packages/
Apply the compatibility patch:

python3 scripts/patch-plugin.py
Test:

opencode run "Hello"

Multi-Account Management

How Auto-Rotation Works

The plugin automatically monitors quota and rate limits. When a request hits a rate limit (HTTP 429) or soft quota threshold:

switch_on_first_rate_limit: true immediately selects the next available account.
scheduling_mode: "balance" distributes requests to maximize availability.
If an account temporarily enters a cooldown, it automatically recovers once the rate limit reset time passes.

Adding More Accounts

To add another Google account to the rotation pool:

opencode auth login

Select Google -> OAuth with Google (Antigravity).
Complete authentication in your browser.
The new account will be added to ~/.config/opencode/antigravity-accounts.json and immediately included in rotation.

Managing or Checking Account Quotas

Run opencode auth login and choose:

Check quotas: View remaining fraction of API quota for each account.
Manage accounts: Enable or disable specific accounts for rotation.

Changing Default Models

To change the default model, edit ~/.config/opencode/opencode.json:

json

{
  "model": "google/antigravity-gemini-3.7-flash",
  "small_model": "google/antigravity-gemini-3.7-flash"
}

Available Antigravity models you can set:

"google/antigravity-gemini-3.7-flash" — Gemini 3.7 Flash with thinking
"google/antigravity-gemini-3.1-pro" — Gemini 3.1 Pro with thinking
"google/antigravity-claude-sonnet-4-6" — Claude Sonnet 4.6
"google/antigravity-claude-opus-4-6-thinking" — Claude Opus 4.6 Thinking

You can also specify models per command:

opencode run "Write a compiler in Rust" --model google/antigravity-claude-opus-4-6-thinking --variant max

Troubleshooting

1. Resetting Stale Rate Limits or Disabled Accounts

If accounts were marked disabled or stuck in a cooldown from previous network errors:

bash

python3 - <<'PY'
import json
p = "/root/.config/opencode/antigravity-accounts.json"  # or ~/.config/opencode/...
with open(p) as f: d = json.load(f)
for a in d.get("accounts", []):
    a["enabled"] = True
    for k in ["rateLimitResetTimes", "coolingDownUntil", "cooldownReason", "verificationRequired", "verificationRequiredAt", "verificationRequiredReason", "verificationRequiredType", "verificationUrl"]:
        a.pop(k, None)
with open(p, "w") as f: json.dump(d, f, indent=2)
print("Accounts reset and enabled!")
PY

2. Re-applying Plugin Patches After npm Updates

If OpenCode or npm updates the plugin in the future, simply re-run:

python3 scripts/patch-plugin.py

3. Port Conflict during `opencode auth login` (Port 51121)

If the local auth server port is blocked:
