caam（caam 命令行）

CAAM — Coding Agent Account Manager

A Go CLI for instant account switching between fixed-cost AI coding subscriptions (Claude Max, GPT Pro, Gemini Ultra). When you hit rate limits, swap accounts in ~50ms instead of 30-60 seconds of browser OAuth friction.

Why This Exists

You're paying $200-275/month for fixed-cost AI coding subscriptions. These plans have rolling usage limits—not billing caps, but rate limits that reset over time. When you hit them mid-flow:

The Problem:

/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, 5+ times per day across multiple tools.

The Solution:

caam activate claude bob@gmail.com   # ~50ms, done

No browser. No OAuth dance. No interruption to your flow state.

How It Works

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

~/.claude.json ←→ ~/.local/share/caam/vault/claude/alice@gmail.com/
~/.codex/auth.json ←→ ~/.local/share/caam/vault/codex/work@company.com/

That's it. No daemons, no databases, no network calls. Just cp with extra steps.

Why This Works

OAuth tokens are bearer tokens—possession equals access. The CLI tools don't fingerprint your machine beyond what's already in the token file. Swapping files is equivalent to "being" that authenticated session.

Profile Detection

caam status uses content hashing:

1. SHA-256 hash current auth files
2. Compare against all vault profiles
3. Match = that's what's active

This means:

• Profiles are detected even if you switched manually
• No hidden state files that can desync
• Works correctly after reboots

Quick Start

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

# Backup current account
caam backup claude alice@gmail.com

# Clear and login to another account
caam clear claude
claude  # /login with bob@gmail.com
caam backup claude bob@gmail.com

# Switch instantly forever
caam activate claude alice@gmail.com   # < 100ms
caam activate claude bob@gmail.com     # < 100ms

# Check status
caam status

Two Operating Modes

1. Vault Profiles (Simple Switching)

Swap auth files in place. One account active at a time per tool. Instant switching.

caam backup claude work@company.com
caam activate claude personal@gmail.com

Use when: You want to switch between accounts sequentially (most common).

2. Isolated Profiles (Parallel Sessions)

Run multiple accounts simultaneously with full directory isolation.

caam profile add codex work@company.com
caam profile add codex personal@gmail.com
caam exec codex work@company.com -- "implement feature X"
caam exec codex personal@gmail.com -- "review code"

Each profile gets its own $HOME and $CODEX_HOME with symlinks to your real .ssh, .gitconfig, etc.

Use when: You need two accounts running at the same time in different terminals.

Supported Tools

Tool-Specific Details

Claude Code (Claude Max)

• Login: /login inside CLI
• Rate Limits: 5-hour rolling usage window
• Notes: When you hit limits, you'll see rate limit messages. Switch accounts to continue.

Codex CLI (GPT Pro)

• Login: codex login or codex login --device-auth (headless)
• Notes: Respects CODEX_HOME. CAAM enforces file-based auth by writing cli_auth_credentials_store = "file" to ~/.codex/config.toml.

Gemini CLI (Google One AI Premium)

• Login: Start gemini, select "Login with Google" or use /auth to switch modes
• Notes: OAuth cache stored in oauth_credentials.json, API key mode uses .env.

Smart Profile Management

Profile Isolation (Advanced)

Smart Profile Management

When you have multiple accounts across multiple providers, manually tracking which account has headroom becomes tedious. Smart Profile Management automates this decision-making.

Profile Health Scoring

Each profile displays a health indicator:

Health scoring combines:

• Token expiry: Time until OAuth token expires
• Error history: Recent authentication or rate limit errors
• Penalty score: Accumulated issues with exponential decay (20% reduction every 5 minutes)
• Plan type: Enterprise/Pro plans get slight scoring boosts

After ~30 minutes of no errors, penalty score returns to near zero.

Proactive Token Refresh

CAAM automatically refreshes OAuth tokens before they expire, preventing mid-session auth failures.

Smart Rotation Algorithms

When you run caam activate claude --auto:

Configure in ~/.caam/config.yaml:

stealth:
  rotation:
    enabled: true
    algorithm: smart  # smart | round_robin | random
  cooldown:
    enabled: true     # Warn when activating cooldown profiles

Cooldown Tracking

When an account hits a rate limit, mark it so rotation skips it:

# Mark current Claude profile (default: 60 min cooldown)
caam cooldown set claude

# Specify profile and duration
caam cooldown set claude/work@company.com --minutes 120

# View active cooldowns
caam cooldown list

# Clear a cooldown early
caam cooldown clear claude/work@company.com

When stealth.cooldown.enabled: true, activating a profile in cooldown warns and prompts for confirmation. Use --force to bypass.

Automatic Failover with caam run

Wrap CLI execution with automatic rate limit handling:

caam run claude -- "explain this code"

# If Claude hits rate limit mid-session:
# 1. Current profile goes into cooldown
# 2. Next best profile selected via rotation
# 3. Command re-executed with new account

Options:

Zero-friction aliases:

alias claude='caam run claude --'
alias codex='caam run codex --'
alias gemini='caam run gemini --'

Now claude "explain this" handles rate limits transparently.

Project-Profile Associations

Link profiles to project directories:

cd ~/projects/work-app
caam project set claude work@company.com

# Now whenever you're in this directory
caam activate claude  # Automatically uses work@company.com

Associations cascade: setting on /home/user/projects applies to all subdirectories unless a more specific association exists.

TUI shortcut: Press p to set the current profile as default for your working directory.

Preview Rotation Selection

$ caam next claude
Recommended: bob@gmail.com
  + Healthy token (expires in 4h 32m)
  + Not used recently (2h ago)

Alternatives:
  alice@gmail.com - Used recently (15m ago)

In cooldown:
  carol@gmail.com - In cooldown (45m remaining)

Useful for understanding rotation choices or scripting conditional logic.

Usage Analytics

CAAM tracks activation patterns and session durations across profiles, helping you understand usage distribution.

TUI Dashboard

Interactive terminal UI for visual profile management:

caam tui

TUI Features

• Visual profile list with health indicators
• Cooldown status display
• Project associations in status bar
• Hot reload: auto-refreshes when profiles are modified in another terminal

Workflow Examples

Daily Workflow

# Morning: Check what's active
caam status
# claude: alice@gmail.com (active)
# codex:  work@company.com (active)
# gemini: personal@gmail.com (active)

# Afternoon: Hit Claude usage limit
caam activate claude bob@gmail.com
claude  # Continue immediately with new account

Initial Multi-Account Setup

# 1. Login to first account using normal flow
claude  # /login → authenticate with alice@gmail.com

# 2. Backup the auth using email as profile name
caam backup claude alice@gmail.com

# 3. Clear and login to second account
caam clear claude
claude  # /login → authenticate with bob@gmail.com

# 4. Backup that too
caam backup claude bob@gmail.com

# 5. Switch instantly forever!
caam activate claude alice@gmail.com   # < 100ms
caam activate claude bob@gmail.com     # < 100ms

Parallel Sessions Setup

# Create isolated profiles
caam profile add codex work@company.com
caam profile add codex personal@gmail.com

# Login to each (one-time, opens browser)
caam login codex work@company.com
caam login codex personal@gmail.com

# Run simultaneously in different terminals
caam exec codex work@company.com -- "implement auth system"
caam exec codex personal@gmail.com -- "review PR #123"

Smart Rotation Workflow

# Let rotation pick the best profile
caam activate claude --auto
# Using rotation: claude/bob@gmail.com
# Recommended: bob@gmail.com
#   + Healthy token (expires in 4h 32m)
#   + Not used recently (2h ago)

# Hit a rate limit? Mark it
caam cooldown set claude
# Recorded cooldown for claude/bob@gmail.com until 14:30 (58m remaining)

# Next activation picks another profile automatically
caam activate claude --auto
# Using rotation: claude/alice@gmail.com

Zero-Friction Mode

# Add aliases to .bashrc/.zshrc
alias claude='caam run claude --'
alias codex='caam run codex --'

# Use tools normally
claude "explain this authentication flow"

# If rate limited mid-session, caam automatically:
# 1. Marks current profile as in cooldown
# 2. Selects next best profile via rotation
# 3. Re-runs command with new profile
# All transparent - you just see the output

Installation

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

# From source

cd coding_agent_account_manager
go build -o caam ./cmd/caam
sudo mv caam /usr/local/bin/

# Go install
go install github.com/Dicklesworthstone/coding_agent_account_manager/cmd/caam@latest

Tips

1. Use actual email as profile name — self-documenting, never forget which account
2. Backup before clearing: caam backup claude current@email.com && caam clear claude
3. Use --backup-current flag: caam activate claude new@email.com --backup-current
4. Check status often: caam status shows what's active across all tools
5. Don't sync vault across machines — auth tokens often contain machine-specific identifiers
6. Use caam paths — if auth file locations change in tool updates, this shows current paths

FAQ

Q: Does this work with API keys? No. CAAM is for fixed-cost subscription plans (Claude Max, GPT Pro, Gemini Ultra) that use OAuth. API keys don't need switching—just use different keys.

Q: Is this against terms of service? No. You're using your own legitimately-purchased subscriptions. CAAM manages local auth files—it doesn't share accounts, bypass rate limits, or modify API traffic. Each account still respects its individual usage limits.

Q: What if the tool updates and changes auth file locations? Run caam paths to see current locations. If they change, we'll update CAAM. File an issue if you notice a discrepancy.

Q: Can I sync the vault across machines? Don't. Auth tokens often contain machine-specific identifiers (device IDs, etc.). Backup and restore on each machine separately.

Q: What's the difference between vault and isolated profiles?

• Vault profiles (backup/activate): Swap auth in place, one account active at a time
• Isolated profiles (profile add/exec): Full directory isolation, run multiple accounts simultaneously

Q: Will switching break running sessions? May cause auth errors in running CLI. Best practice: switch before starting a new session, not during.

Q: How do I know which account I'm currently using? Run caam status. It shows the active profile for each tool based on content hash matching.
