⚡ Quick Start

Prefer manual setup? Here are the essential commands:

# Install with uv (recommended - fast, cross-platform, automatic PATH setup)
uv tool install ai-shell-command-generator

# Use with free local AI (no API key needed)
ai-shell -p ollama -q "find large files"

# Or use with cloud AI (interactive setup on first run)
ai-shell -p openai -q "find large files"

# Learn while you generate
ai-shell --teach -p ollama -q "backup my documents"

🚀 Installation

Option 1: Using uv (⭐ Recommended)

uv is the fastest, most reliable way to install Python CLI tools. It handles PATH setup automatically on all platforms.

# Install uv (one-time setup)
# macOS/Linux:
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell):
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# Then install ai-shell (works immediately, no PATH configuration needed!)
uv tool install ai-shell-command-generator

# Update to latest version
uv tool upgrade ai-shell-command-generator

# Uninstall cleanly
uv tool uninstall ai-shell-command-generator

Why uv?

• ✅ 10-100x faster than traditional package managers (written in Rust)
• ✅ Automatic PATH setup - works immediately on Windows/Mac/Linux
• ✅ Isolated environments - doesn't pollute your Python installation
• ✅ Simple updates - uv tool upgrade keeps you current
• ✅ Clean uninstall - removes everything cleanly

From Source (Development)

git clone https://github.com/codingthefuturewithai/ai-shell-command-generator.git
cd ai-shell-command-generator

# Install with all development dependencies
uv pip install -e ".[dev]"

Requirements: Python 3.10 or higher, uv installed

Development Setup

# Run tests
uv run pytest tests/ -v

🔑 API Key Setup

Option 1: Automatic Setup (Easiest for Beginners)

Just run the tool! When you select OpenAI or Anthropic for the first time:

ai-shell -p openai -q "your query"

You'll be prompted:

🔑 OpenAI API Key Required

What would you like to do?
1. Enter my OpenAI API key now (I'll save it for you)
2. I'll set it manually via environment variable
3. Use Ollama instead (free, no API key needed)

Select option 1, paste your key, and it's saved to ~/.ai-shell-env forever!

Option 2: Manual Setup

Environment Variables (All Platforms)

# Linux/macOS
export OPENAI_API_KEY="your-key-here"
export ANTHROPIC_API_KEY="your-key-here"

# Windows PowerShell
$env:OPENAI_API_KEY="your-key-here"
$env:ANTHROPIC_API_KEY="your-key-here"

Project-Specific (.env file)

# Create .env in your project directory
echo "OPENAI_API_KEY=your-key-here" > .env
echo "ANTHROPIC_API_KEY=your-key-here" >> .env

Global Config (Persistent)

# Create ~/.ai-shell-env in your home directory
cat > ~/.ai-shell-env << EOF
OPENAI_API_KEY=your-key-here
ANTHROPIC_API_KEY=your-key-here
EOF

Option 3: Ollama (No API Key Needed!)

# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Pull a model
ollama pull gpt-oss:latest

# Use immediately
ai-shell -p ollama -q "find large files"

Recommended models:

• gpt-oss:latest - OpenAI's GPT-OSS model
• qwen2.5-coder:7b - Excellent for coding tasks
• deepseek-r1:8b - Good reasoning capabilities
• mistral-nemo:12b - Balanced performance

Where AI Shell Looks for API Keys

Priority order:

1. Environment variables (you set with export)
2. ./.env file in current directory
3. ~/.ai-shell-env file in your home directory
4. Prompts you to enter and saves to ~/.ai-shell-env

Simple and predictable!

Non-Interactive Mode

Perfect for scripts and automation:

# Basic usage (shell required for safety)
ai-shell -p ollama -s bash -q "find all Python files modified today"

# With OpenAI
ai-shell -p openai -m gpt-5-nano -s bash -q "compress directory"

# With Anthropic
ai-shell -p anthropic -m claude-3-5-haiku-20241022 -s bash -q "backup documents"

# Auto-copy to clipboard
ai-shell -p ollama -s bash -q "show disk usage" --copy

# Disable risk check (for trusted automation)
ai-shell -p ollama -s bash -q "clean temp files" --no-risk-check

# Windows PowerShell
ai-shell -p ollama -s powershell -q "find large files"

# Windows CMD
ai-shell -p ollama -s cmd -q "list files"

⚠️ Note: Shell (-s) is required in non-interactive mode for safety. This prevents wrong commands in CI/CD pipelines.

Utility Commands

# Check version
ai-shell --version

# List available models for a provider
ai-shell --list-models openai
ai-shell --list-models anthropic
ai-shell --list-models ollama

📚 Teaching Mode

Learn shell commands while generating them:

# Start in teaching mode
ai-shell --teach -p ollama -q "find files modified in last 24 hours"

What you get:

═══════════════════════════════════════════════════════════
📚 TEACHING MODE
═══════════════════════════════════════════════════════════

COMMAND:
  find . -type f -mtime -1

BREAKDOWN:
  find . - search from current directory
  -type f - only files (not directories)
  -mtime -1 - modified in last 24 hours

OS NOTES:
  macOS uses BSD find (no -printf option)
  -mtime uses 24-hour periods
  Use -mmin for minute-level precision

SAFER APPROACH:
  find . -type f -mtime -1 -ls
  (preview files before any action)

WHAT YOU LEARNED:
  ✓ find searches recursively by default
  ✓ -mtime uses days, -mmin uses minutes
  ✓ Negative numbers mean "less than"
  ✓ Always preview before destructive operations

Interactive teaching features:

• Ask questions - "What does -mtime mean?"
• See examples - Variations with different options
• What-if scenarios - "What if I only want .txt files?"
• Alternative approaches - Different ways to solve the same problem

# List available models
ollama list

# Pull a model
ollama pull gpt-oss:latest

Shell Issues

Wrong command syntax generated:

• Make sure you specified the correct shell with -s
• In non-interactive mode, shell is REQUIRED
• Check: ai-shell -s powershell -q "query" for PowerShell
• Check: ai-shell -s cmd -q "query" for Windows CMD

Shell not detected correctly:

• Override in interactive mode when prompted
• Or specify explicitly with -s bash or -s powershell

Platform-Specific

Windows:

• PowerShell and CMD both supported
• Git Bash works with -s bash
• WSL works with -s bash

macOS:

• Uses BSD-compatible commands automatically
• Both bash and zsh supported (zsh uses bash mode)
