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.

Installation

Via npm (Recommended)

pi install npm:pi-antigravity-multi-account

To upgrade:

pi update npm:pi-antigravity-multi-account

Via Git

pi install git:andrraa/pi-antigravity

To upgrade:

pi update git:andrraa/pi-antigravity

Multi-Account Guide

Manage accounts and quotas using the /antigravity.account command:

Subcommand Syntax Description
(none) /antigravity.account Open interactive terminal account picker
login /antigravity.account login <alias> Authenticate a new Google account via OAuth and assign an alias
use / switch /antigravity.account use <alias> Switch active account and trigger live session reload
list / ls /antigravity.account list List all saved accounts with active account indicator (● [active])
usage / quota /antigravity.account usage Check real-time quota status across all saved accounts
save /antigravity.account save <alias> Save current active session credentials under a new alias
rename /antigravity.account rename <old> <new> Rename an existing account alias
delete / rm /antigravity.account delete <alias> Remove an account from storage
