World's first real-time command education tool - Learn terminal commands as you type with instant descriptions, safety warnings, and intelligent suggestions!

🎯 What Makes Terminal Tutor Revolutionary?

Terminal Tutor is the first and only terminal education tool that provides real-time command descriptions as you type - literally keystroke by keystroke. No more waiting, no more guessing, no more dangerous mistakes.

⚡ Real-Time Magic in Action

# As you type "git st" - predictions appear instantly:
$ git st█                           # ← You're typing here
🟢 SAFE - Show working tree status   # ← Live prediction appears below

Performance: 1.4-2.0ms response time (96% faster than target!) ⚡

⚠️ Requirements - Install Zsh First!

REQUIRED:

• ✅ Zsh shell - Real-time predictions ONLY work in Zsh (Bash/Fish not supported yet)
• ✅ Python 3.7+ - Python runtime required
• ✅ macOS/Linux - Native Unix support
• ✅ Windows - Via Git Bash or WSL2 (native PowerShell coming 2026)

Step 1: Check if you have Zsh installed

# Check if Zsh is installed:
which zsh

# ✅ If it shows: /bin/zsh or /usr/bin/zsh → Zsh is installed! Go to Step 2
# ❌ If it shows: nothing or "zsh not found" → Install Zsh in Step 2

Step 2: Install Zsh (if needed)

# macOS (Zsh pre-installed on macOS 10.15+)
# Skip to Step 3!

# Ubuntu/Debian/Linux Mint
sudo apt update && sudo apt install zsh

# Fedora/RHEL/CentOS
sudo dnf install zsh

# Arch Linux
sudo pacman -S zsh

Step 3: Switch to Zsh

Option A: Try Zsh NOW (temporary - recommended for testing)

zsh
# ↑ You're now in Zsh! Perfect for testing Terminal Tutor.
# To exit Zsh and return to your previous shell, type: exit

Option B: Make Zsh your DEFAULT shell (permanent)

chsh -s $(which zsh)
# ⚠️ Will ask for your password (your macOS/Linux login password - this is normal!)
# ℹ️ If you see "no changes made" → You're already on Zsh! Success!
# Close terminal and reopen → You'll be in Zsh automatically

# Verify it worked:
echo $SHELL  # Should show: /bin/zsh

💡 Recommended: Try Option A first to test Terminal Tutor, then use Option B to make it permanent if you like it!

🚀 Quick Start (2 minutes to awesome)

Step 1: Install with uv (recommended)

# Install uv if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install Terminal Tutor with uv
uv tool install terminal-tutor

Alternative: Install with pipx

# If you prefer pipx
pipx install terminal-tutor

Step 2: Activate real-time predictions

# Activate the magic (adds to ~/.zshrc)
terminal-tutor install

# Restart Zsh to load integration
exec zsh

Step 3: Test it works!

# Start typing slowly... watch predictions appear!
git st█
# You should see: 🟢 SAFE - Show working tree status

# Verify installation
terminal-tutor status
# Should show: 🟢 Enabled

You're now a command-line wizard! ✨

🌟 Core Features

🔮 Real-Time Predictions (Zsh - World First!)

• Keystroke-by-keystroke command education
• 1.4-2.0ms lightning-fast response time (avg 1.6ms)
• Live descriptions appear as you type
• Zero latency user experience

🧠 Intelligent Fuzzy Matching

• State-of-the-art algorithm with exponential position decay
• Surgical precision - no irrelevant suggestions
• Context-aware recommendations
• FZF-inspired smart scoring

# Smart suggestions for partial input (use debug for performance metrics)
$ terminal-tutor debug "git s"
───────────────────────────────────
🟢 SAFE git status - Show the working tree status
🟡 CAUTION git stash - Stash changes in a dirty working directory
🟢 SAFE git show - Show various types of objects
───────────────────────────────────
⏱️  1.2ms | 📊 3 matches | 🔍 fuzzy

🗣️ Natural Language Command Discovery

# Ask in plain English, get exact commands
$ terminal-tutor ask "how to list files"
ls - 🟢 SAFE - List directory contents

$ terminal-tutor ask "copy files recursively"
cp -r - 🟢 SAFE - Copy directories recursively

First-time setup: The ask mode requires an OpenAI API key. On first use, you'll be prompted to enter your key. Get one here: https://platform.openai.com/api-keys

# Configure API key manually
$ terminal-tutor config api-key set

# Check API key status
$ terminal-tutor config api-key status

# Remove stored API key
$ terminal-tutor config api-key clear

Security: API keys are stored in ~/.terminal_tutor_openai_key with 600 permissions (user read/write only) and never echoed to the terminal.

🛡️ Advanced Safety System

• 🟢 SAFE / 🟡 CAUTION / 🔴 DANGEROUS risk levels
• Smart pattern recognition for destructive commands
• Context-aware warnings with safety prompts
• False positive elimination through machine learning

📚 Comprehensive Command Database (459+ commands)

• Git: Complete workflow coverage (13 commands)
• Docker: Container lifecycle management (15 commands)
• Kubernetes: Cluster operations (13 commands)
• AWS CLI: Full cloud platform coverage (96 commands)
• System Commands: Unix/Linux essentials (41+ commands)
