dsh-antigravity

Google Antigravity / Cloud Code Assist model provider for DeepSeek Harness.

This is a DSH Web plugin, not a Pi extension. It registers a DSH LlmAdapter under provider route antigravity, stores OAuth credentials under DSH home, and talks to the Cloud Code Assist streaming API directly.

Unofficial integration. This project is not affiliated with or endorsed by Google. Use it only with accounts and services you are authorized to access.

Install into DSH Web

Option 1: Direct from GitHub

dsh plugin --profile web add github:LiZhenNet/dsh-antigravity

Option 2: From Local Release Tarball

npm run pack:dist
dsh plugin --profile web add ./dist/dsh-antigravity-0.0.1.tgz

The package declares a DSH bundle patch, so installation automatically mounts the host plugin and browser settings page.

If your DSH version does not support dsh plugin add, copy the package into the Web profile manually:

cp -R dsh-antigravity "$DSH_HOME/profiles/web/node_modules/"

Then add the plugin to the profile cordis.patch.yml:

- insert:
    - id: llm-antigravity
      name: dsh-antigravity

Restart DSH:

dsh web

Login

Open Settings > Antigravity and click Login. The settings page starts Google OAuth and refreshes quota after login completes.

After login, the settings page displays account information, live quota bars, reset times, and model selector options:

The plugin starts a loopback OAuth callback server at http://localhost:51121/oauth-callback. If the Web service cannot open a browser, run the terminal helper on the same machine:

node "$DSH_HOME/profiles/web/node_modules/dsh-antigravity/bin/antigravity-login.mjs"

Credentials are stored at:

$DSH_HOME/storages/antigravity-oauth.json

Keep that file private. It contains access and refresh tokens.

After login, select the Antigravity provider in DSH's model picker.
