```

#### Install and run the monitor
```bash
# Install dependencies
npm install -g ccusage

# Clone and install the tool with uv
git clone https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor.git
cd Claude-Code-Usage-Monitor
uv tool install .

# Run from anywhere
ccusage-monitor
# or
claude-monitor
```

### 🔧 Legacy Installation Methods

#### Quick Start (Development/Testing)

For immediate testing or development:

```bash
# Install dependencies
npm install -g ccusage
pip install pytz

# Clone and run
git clone https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor.git
cd Claude-Code-Usage-Monitor
python claude_monitor.py
```

#### Prerequisites

1. **Python 3.7+** installed on your system
2. **Node.js** for ccusage CLI tool

#### Virtual Environment Setup

#### Why Use Virtual Environment?

Using a virtual environment is **strongly recommended** because:

- **🛡️ Isolation**: Keeps your system Python clean and prevents dependency conflicts
- **📦 Portability**: Easy to replicate the exact environment on different machines
- **🔄 Version Control**: Lock specific versions of dependencies for stability
- **🧹 Clean Uninstall**: Simply delete the virtual environment folder to remove everything
- **👥 Team Collaboration**: Everyone uses the same Python and package versions

#### Installing virtualenv (if needed)

If you don't have `venv` module available:

```bash
# Ubuntu/Debian
sudo apt-get update
sudo apt-get install python3-venv

# Fedora/RHEL/CentOS
sudo dnf install python3-venv

# macOS (usually comes with Python)
# If not available, install Python via Homebrew:
brew install python3

# Windows (usually comes with Python)
# If not available, reinstall Python from python.org
# Make sure to check "Add Python to PATH" during installation
```

Alternatively, use the `virtualenv` package:
```bash
# Install virtualenv via pip
pip install virtualenv

# Then create virtual environment with:
virtualenv venv
# instead of: python3 -m venv venv
```

#### Step-by-Step Setup

```bash
# 1. Install ccusage globally
npm install -g ccusage

# 2. Clone the repository
git clone https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor.git
cd Claude-Code-Usage-Monitor

# 3. Create virtual environment
python3 -m venv venv
# Or if using virtualenv package:
# virtualenv venv

# 4. Activate virtual environment
# On Linux/Mac:
source venv/bin/activate
# On Windows:
# venv\Scripts\activate

# 5. Install Python dependencies
pip install pytz

# 6. Make script executable (Linux/Mac only)
chmod +x claude_monitor.py

# 7. Run the monitor
python claude_monitor.py
```

#### Daily Usage

After initial setup, you only need:

```bash
# Navigate to project directory
cd Claude-Code-Usage-Monitor

# Activate virtual environment
source venv/bin/activate  # Linux/Mac
# venv\Scripts\activate   # Windows

# Run monitor
./claude_monitor.py  # Linux/Mac
# python claude_monitor.py  # Windows

# When done, deactivate
deactivate
```

#### Pro Tip: Shell Alias

Create an alias for quick access:
```bash
# Add to ~/.bashrc or ~/.zshrc
alias claude-monitor='cd ~/Claude-Code-Usage-Monitor && source venv/bin/activate && ./claude_monitor.py'

# Then just run:
claude-monitor
```

## ✨ Features & How It Works

### Current Features

#### 🔄 Real-time Monitoring
- Updates every 3 seconds with smooth refresh
- No screen flicker - intelligent display updates
- Live token consumption tracking across multiple sessions

#### 📊 Visual Progress Bars
- **Token Progress**: Color-coded bars showing current usage vs limits
- **Time Progress**: Visual countdown to next session reset
- **Burn Rate Indicator**: Real-time consumption velocity

#### 🔮 Smart Predictions
- Calculates when tokens will run out based on current burn rate
- Warns if tokens will deplete before next session reset
- Analyzes usage patterns from the last hour

#### 🤖 Auto-Detection System
- **Smart Plan Switching**: Automatically switches from Pro to custom_max when limits exceeded
- **Limit Discovery**: Scans previous sessions to find your actual token limits
- **Intelligent Notifications**: Shows when automatic switches occur

### Understanding Claude Sessions

#### How Claude Code Sessions Work

Claude Code operates on a **5-hour rolling session window system**:

1. **Session Start**: Begins with your first message to Claude
2. **Session Duration**: Lasts exactly 5 hours from that first message
3. **Token Limits**: Apply within each 5-hour session window
4. **Multiple Sessions**: Can have several active sessions simultaneously
5. **Rolling Windows**: New sessions can start while others are still active

#### Session Reset Schedule

**Default reference times** (in your configured timezone):
- `04:00`, `09:00`, `14:00`, `18:00`, `23:00`

> **⚠️ Important**: These are reference times for planning. Your actual token refresh happens exactly 5 hours after YOUR first message in each session.

**Example Session Timeline:**
```
10:30 AM - First message (Session A starts)
03:30 PM - Session A expires (5 hours later)

12:15 PM - First message (Session B starts)
05:15 PM - Session B expires (5 hours later)
```

#### Burn Rate Calculation

The monitor calculates burn rate using sophisticated analysis:

1. **Data Collection**: Gathers token usage from all sessions in the last hour
2. **Pattern Analysis**: Identifies consumption trends across overlapping sessions
3. **Velocity Tracking**: Calculates tokens consumed per minute
4. **Prediction Engine**: Estimates when current session tokens will deplete
5. **Real-time Updates**: Adjusts predictions as usage patterns change

### Token Limits by Plan

#### Standard Plans

| Plan | Approximate Limit | Typical Usage |
|------|------------------|---------------|
| **Claude Pro** | ~7,000 tokens | Light coding, testing, learning |
| **Claude Max5** | ~35,000 tokens | Regular development work |
| **Claude Max20** | ~140,000 tokens | Heavy usage, large projects |

#### Auto-Detection Plans

| Plan | How It Works | Best For |
|------|-------------|----------|
| **custom_max** | Scans all previous sessions, uses highest token count found | Users with variable/unknown limits |

### Smart Detection Features

#### Automatic Plan Switching

When using the default Pro plan:

1. **Detection**: Monitor notices token usage exceeding 7,000
2. **Analysis**: Scans previous sessions for actual limits
3. **Switch**: Automatically changes to custom_max mode
4. **Notification**: Displays clear message about the change
5. **Continuation**: Keeps monitoring with new, higher limit

#### Limit Discovery Process

The auto-detection system:

1. **Scans History**: Examines all available session blocks
2. **Finds Peaks**: Identifies highest token usage achieved
3. **Validates Data**: Ensures data quality and recency
4. **Sets Limits**: Uses discovered maximum as new limit
5. **Learns Patterns**: Adapts to your actual usage capabilities


## 🚀 Usage Examples

### Common Scenarios

#### 🌅 Morning Developer
**Scenario**: You start work at 9 AM and want tokens to reset aligned with your schedule.

```bash
# Set custom reset time to 9 AM
./claude_monitor.py --reset-hour 9

# With your timezone
./claude_monitor.py --reset-hour 9 --timezone US/Eastern
```

**Benefits**:
- Reset times align with your work schedule
- Better planning for daily token allocation
- Predictable session windows

#### 🌙 Night Owl Coder
**Scenario**: You often work past midnight and need flexible reset scheduling.

```bash
# Reset at midnight for clean daily boundaries
./claude_monitor.py --reset-hour 0

# Late evening reset (11 PM)
./claude_monitor.py --reset-hour 23
```

**Strategy**:
- Plan heavy coding sessions around reset times
- Use late resets to span midnight work sessions
- Monitor burn rate during peak hours

#### 🔄 Heavy User with Variable Limits
**Scenario**: Your token limits seem to change, and you're not sure of your exact plan.

```bash
# Auto-detect your highest previous usage
claude-monitor --plan custom_max

# Monitor with custom scheduling
claude-monitor --plan custom_max --reset-hour 6
```

**Approach**:
- Let auto-detection find your real limits
- Monitor for a week to understand patterns
- Note when limits change or reset

#### 🌍 International User
**Scenario**: You're working across different timezones or traveling.

```bash
# US East Coast
claude-monitor --timezone America/New_York

# Europe
claude-monitor --timezone Europe/London

# Asia Pacific
claude-monitor --timezone Asia/Singapore

# UTC for international team coordination
claude-monitor --timezone UTC --reset-hour 12
```

#### ⚡ Quick Check
**Scenario**: You just want to see current status without configuration.

```bash
# Just run it with defaults
ccusage-monitor

# Press Ctrl+C after checking status
```

### Plan Selection Strategies

#### How to Choose Your Plan

**Start with Default (Recommended for New Users)**
```bash
# Pro plan detection with auto-switching
ccusage-monitor
```
- Monitor will detect if you exceed Pro limits

## Troubleshooting

### No active session found
If you encounter the error `No active session found`, please follow these steps:

1. **Initial Test**:
   Launch Claude Code and send at least two messages. In some cases, the session may not initialize correctly on the first attempt, but it resolves after a few interactions.

2. **Configuration Path**:
   If the issue persists, consider specifying a custom configuration path. By default, Claude Code uses `~/.config/claude`. You may need to adjust this path depending on your environment.

```bash
CLAUDE_CONFIG_DIR=~/.config/claude ./claude_monitor.py
```
