README

Overview

pi-antigravity-multi-account is a native provider extension for the Pi Coding Agent that enables direct access to Google Cloud Code and Antigravity models (Gemini Flash, Claude 3.7/Sonnet, Opus, and GPT-OSS).

It features native OAuth authentication, seamless switching across multiple Google accounts, real-time quota pool monitoring, and automatic token refresh without requiring external CLI dependencies.

Features

  • Standalone Native Provider: Direct streamSimple implementation with zero external binaries or CLI dependencies.
  • Interactive Account Switcher: Select and switch accounts dynamically via a terminal picker (/antigravity.account).
  • Single-Step Alias Authentication: Link multiple Google accounts under custom named aliases (/antigravity.account login <alias>).
  • Simultaneous Quota Dashboard: Inspect remaining hourly and weekly quota pools across all stored accounts simultaneously.
  • Zero-Downtime Session Reloading: Switching accounts purges model/project caches and invokes live session reloading immediately.
  • Resilient Request Handling: Exponential backoff retry with jitter on 429 (Too Many Requests) and 503 (Service Unavailable).
  • Connection Prewarming: Pre-establishes TLS handshakes with persistent keep-alive pools to eliminate cold-start latency.
  • Secure Local Storage: Credentials are saved to ~/.pi/agent/antigravity-accounts.json with strict POSIX 0o600 permissions.

Compatibility

  • Requires Pi 1.3.0 or newer; development and regression tests target 1.3.0.
  • This remains a native Cloud Code provider, not a wrapper around agy. Existing Pi OAuth and account aliases stay independent of Google's shared OS-keyring login.
  • Google's official CLI installer resolved to 1.4.2 when checked on October 20, 2026. Its release version does not establish compatibility with this unofficial wire protocol.
  • The native User-Agent uses CLI 1.4.2 and build changelist 1001591392 extracted from the installed official binary. This is static verification, not a captured runtime request; enterprise/ADC authentication, shared keyring credentials, and full CLI parity are not claimed.
  • Pi request payload, response-header, and provider-stream observation hooks are supported.
