Google Antigravity provider #

Login + streaming provider for Google Cloud Code Assist ("Antigravity"). Ported from oh-my-pi's google-antigravity implementation, including:

• OAuth flow with tier eligibility check and free-tier provisioning
• antigravity/hub/<version> User-Agent spoofing with live version discovery
• The per-request Antigravity envelope (agent/<agentId>/<ts>/<trajectoryId>/<step>, signed-decimal session id, model_enum / used_claude labels)
• daily-cloudcode-pa.googleapis.com with sandbox failover
• Live model discovery via fetchAvailableModels

Usage #

prime-agent -e ./packages/coding-agent/examples/extensions/google-antigravity
# then:
/login google-antigravity

For auto-discovery, copy this directory to ~/.prime/agent/extensions/.
