Sub-100ms auth switching for AI coding CLIs (Claude Code, Codex, Gemini): swap subscription accounts instantly when you hit usage limits

caam - Coding Agent Account Manager

Sub-100ms account switching for AI coding CLIs with fixed-cost subscription plans. When you hit usage limits on Gemini Max, GPT Pro, or Gemini Ultra, don't wait 60 seconds for browser OAuth—just swap to another account instantly.

curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/coding_agent_account_manager/main/install.sh?$(date +%s)" | bash

Usage:

caam backup gemini alice@gmail.com      # Save current auth
caam activate gemini bob@gmail.com      # Switch instantly

🤖 Agent Quickstart (JSON)

Use --json in agent contexts. stdout = data, stderr = diagnostics, exit 0 = success.

# List available profiles (machine-readable)
caam list --json

# Show current status for all tools
caam status --json

# Switch accounts
caam activate gemini alice@gmail.com --json

The Problem

You're paying $200-275/month for fixed-cost AI coding subscriptions (Gemini Max, GPT Pro, Gemini Ultra). These plans have usage limits—not billing caps, but rate limits that reset over time. When you hit them mid-flow, the official way to switch accounts:

/login → browser opens → sign out of Google → sign into different Google →
authorize app → wait for redirect → back to terminal

That's 30-60 seconds of friction. Multiply by 5+ switches per day across multiple tools.

The Solution

Each AI CLI stores OAuth tokens in plain files. caam backs them up and restores
