amlyczz/dsh-agy-link

Integrate Google Antigravity models into DeepSeek Harness (DSH) through the official, unmodified agy CLI. The plugin provides streaming, thinking, tool activity, token metering, in-GUI OAuth login, and quota monitoring.

Requirements

Requirement	Verification
DSH	dsh --version
Node.js >= 24	node --version
Google Antigravity CLI	agy --version
Google connectivity	proxy/VPN/TUN where required

Where Google is not directly reachable, enable system proxy/TUN mode. If the terminal does not inherit proxy settings, export them before starting DSH:

export HTTPS_PROXY=http://127.0.0.1:7890 HTTP_PROXY=http://127.0.0.1:7890 ALL_PROXY=socks5://127.0.0.1:7890

Replace the port with the correct local proxy port. An HTTP(S) or SOCKS proxy can also be configured per account in the DSH Antigravity panel.

Install and quick start

# Install into the web profile
dsh plugin --profile web add dsh-agy-link

# Start DSH Web
dsh web

In DSH, click the AGY (n) badge and choose Add Account to complete Google login in the browser. Alternatively run /agy auth to start primary-account login. Then choose an Antigravity model from /model and start chatting. Use /agy status to check status.

Features

• Account pool with isolated HOME environments and credentials.
• Sequential failover on HTTP 429 or quota exhaustion.
• Official five-hour and seven-day quota monitoring with reset countdowns.
• Text, thinking, and tool-activity streaming into native DSH UI cards.
• DSH sessions bound to native agy conversations through --conversation.
• Gemini, Claude, and GPT-OSS models available through the antigravity provider.
• Multimodal images staged locally and authorized to agy through --add-dir.
• agy_ask for delegating a one-off task to an Antigravity model.
