The Dilemma: AI Quota Exhaustion & Account Juggling
Google Antigravity is one of the most capable agentic coding systems available today, offering native access to top-tier reasoning engines like Claude 3.5 Sonnet and Gemini Pro. However, any developer or engineering team pushing serious code quickly encounters two painful bottlenecks:
- Strict Rolling Quotas: Heavy coding sessions deplete weekly caps and 5-hour rolling limits within hours.
- The Friction of Multi-Account Management: Many developers, students, and teams maintain multiple accounts—such as GitHub Student Developer Packs, personal accounts, client profiles, and dedicated organizational seats. But toggling between them requires logging out of the browser, clearing session cookies, copying OAuth tokens manually, and re-linking IDE databases.
To eliminate this friction permanently, I architected and released Antigravity Auth Vault (ag-auth)—a high-performance, cross-platform session vault, instant account switcher, and encrypted team database synchronizer.
Key Architectural Highlights
1. Instant 1-Key Profile Switching (<200ms)
By executing the 1-character alias @, developers launch an interactive, arrow-navigable terminal UI that lists all stored accounts, active surface bindings, and real-time AI quota bars. Switching active profiles takes under 200 milliseconds without ever touching a browser.
$ @
Select Universal Antigravity Account (↑/↓ arrow keys, Enter to switch, 1-9 direct, q to cancel):
▶ [1] student-pack@university.edu [Gem: 94.2% | Cld: 100.0%] [CURRENT ACTIVE] (CLI, IDE, App)
[2] work-lead@company.com [Gem: 88.5% | Cld: 100.0%] (CLI, IDE, App)
[3] team-ai-pool@gmail.com [Gem: 76.1% | Cld: 63.4%] (CLI)
[4] sandbox-dev@gmail.com [Gem: 99.0% | Cld: 100.0%] (CLI)
2. Multi-Surface Atomic Synchronization
Unlike basic token scripts that only update CLI configuration, ag-auth atomically updates the state across all three Antigravity surfaces simultaneously:
- Antigravity CLI (
agy): Updates~/.gemini/antigravity-cli/antigravity-oauth-tokenand system credentials. - Antigravity IDE: Atomically patches the SQLite
ItemTableinAntigravity IDE/User/globalStorage/state.vscdb. - Antigravity 2.0 Desktop: Synchronizes session state in
Antigravity/User/globalStorage/state.vscdb.
3. Zero-Knowledge AES-256-CBC Encryption
Security is paramount when handling authentication tokens:
- All sensitive tokens and credentials are encrypted on the client side using AES-256-CBC with key derivation via PBKDF2 (100,000 iterations) and cryptographic salts.
- Native integration with operating system keyrings: Apple Keychain (macOS), Secret Service / libsecret (Linux), and Windows Credential Manager (Windows).
- Local vault files are locked down with strict
0600file permissions.
4. Pooled Team Quotas & Cloud Sync
Engineering teams and student study groups can combine their accounts into a unified, encrypted quota pool. With a single command, connect ag-auth to any serverless PostgreSQL provider (Neon, Supabase, or private PostgreSQL):
ag-auth sync postgres://user:password@ep-cool-pool.neon.tech/neondb?sslmode=require
Every account is encrypted with a team passphrase before hitting the wire, ensuring that even the cloud database provider has zero visibility into plaintext tokens.
Instant 1-Line Execution
No manual NPM publishing or complex setup required. Run directly in any terminal:
npx github:axosecurity/antigravity-auth-vault
What This Does Automatically:
- Provisions the secure vault directory at
~/.antigravity-auth-vault. - Links the
ag-authexecutable and the instant@switcher to your user$PATH. - Enables shell tab autocompletion across
zsh,bash,fish, andPowerShell. - Captures your current session and presents real-time capacity meters.
