dsh-antigravity-oauth

English | 中文

Unofficial Gemini Cloud Code Assist login for DeepSeek Harness.

This is not Google Antigravity, not the public Gemini API, and not an official DeepSeek product.

Warning

Using this plugin can get the Google account banned, limited, or signed out. That risk is real. Nobody here can undo it.

Sign-in pretends to be the Antigravity desktop client (ideType: ANTIGRAVITY) and talks to daily-cloudcode-pa.googleapis.com /v1internal:streamGenerateContent. That is not Google AI Studio, not Vertex, and not a supported third-party integration. Google can change or shut this path without notice.

Read Google Terms of Service and the Antigravity / Gemini product terms before connecting. Prefer a spare Google account. Do not paste .dsh-antigravity-oauth.json, refresh tokens, callback URLs, or authorization codes into issues or screenshots.

The OAuth client id/secret in this repo are the public Antigravity desktop-app client, not your Google password. Account tokens stay in $DSH_HOME/.dsh-antigravity-oauth.json.

If you want a supported Gemini integration, use Google's official API / AI Studio products.

What it does

Settings nav	Antigravity
Harness route	agy-google-antigravity
Public models	gemini-3.8-flash, gemini-3.7-flash, gemini-3.5-flash
Auth file	$DSH_HOME/.dsh-antigravity-oauth.json
Search	search_web as a separate Cloud Code Assist googleSearch turn
Image	Not available on this route

It never reads or writes ~/.gemini, Antigravity app data, dsh-oauth-login's store, or Pi Agent auth.json. Do not merge this plugin with dsh-oauth-login.

It does not offer Claude, GPT-OSS, Gemini 3.6 / 3.1 Pro, official Gemini API keys, multi-account rotation, or DSH web_search / web_fetch on this route.

Install

Node 22.19+. This branch targets DeepSeek Harness 0.1.2-rc.1.

git clone https://github.com/aa2246740/dsh-antigravity-oauth.git
cd dsh-antigravity-oauth
npm install
DSHX_HARNESS=/absolute/path/to/deepseek-harness npm run build
dsh plugin --profile web add file:./dsh-antigravity-oauth

Keep the file: prefix. Restart the Web Host. Open Settings → Antigravity. In a new chat, pick agy-google-antigravity.

Sign in

1. Settings → Antigravity → Sign in.
2. Finish Google's consent screen.
3. If the window does not return, paste the redirect URL or authorization code into the form.

OAuth listens on http://127.0.0.1:51121/oauth-callback. Desktop OAuth here does not use PKCE.

If a turn 400s, TRANSPORT-storms, or leaves an unfinished tool call, start a new chat. Do not Continue that session.

Proxy and config

Settings → Antigravity can use Host environment, direct, or an explicit HTTP(S) proxy. Settings persist in $DSH_HOME/.dsh-antigravity-oauth.json.network.json. SOCKS-only ports are not enough.

- id: llm-antigravity-oauth
  name: dsh-antigravity-oauth
  config:
    nativeTools: true
    nativeSearch: true

Key	Default	Meaning
nativeSearch	true	Offer search_web and intercept it onto googleSearch
nativeTools	true	Forward DSH function tools after schema sanitizing
streamIdleTimeoutMs	300000	Idle stream timeout
retryPolicy	Harness default	Official dsh-llm retry policy

nativeSearch: false turns off Cloud Code Assist search. It does not bring DSH web_search back on this route.
