codeduet --version

macOS Permission Fix (if needed):

# If you get permission errors, use sudo:
sudo npm install -g @codeduet-cli/codeduet-cli@latest

# Or configure npm for user-level installs:
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.zshrc
source ~/.zshrc
npm install -g @codeduet-cli/codeduet-cli@latest

Install from source

git clone https://github.com/CodeDuet/codeduet-cli.git
cd codeduet-cli
npm install

# Install globally (may require sudo on macOS)
npm install -g .
# or with sudo if needed:
sudo npm install -g .

Verify Installation

After installation, test that all commands work:

codeduet --version
cd-cli --version
codeduet-code --version

Quick Start

# Start CodeDuet (multiple ways to launch)
codeduet
# or
cd-cli
# or
codeduet-code

# Example commands
> Explain this codebase structure
> Help me refactor this function
> Generate unit tests for this module

Session Management

Control your token usage with configurable session limits to optimize costs and performance.

Configure Session Token Limit

Create or edit .qwen/settings.json in your home directory:

{
  "sessionTokenLimit": 32000
}

Note: The .qwen directory name is maintained for backwards compatibility.

Memory Files

CodeDuet supports provider-specific memory files to customize AI interactions:

Supported Memory Files:

• CLAUDE.md - Custom instructions for Anthropic Claude interactions
• GEMINI.md - Custom instructions for Google Gemini interactions
• CHATGPT.md - Custom instructions for OpenAI ChatGPT interactions
• GROK.md - Custom instructions for xAI Grok interactions
• QWEN.md - Custom instructions for Qwen models

File Locations:

# Project-specific (highest priority)
./CLAUDE.md
./GEMINI.md  
./CHATGPT.md
./GROK.md
./QWEN.md

# Global (shared across projects)
~/.qwen/CLAUDE.md
~/.qwen/GEMINI.md
~/.qwen/CHATGPT.md
~/.qwen/GROK.md
~/.qwen/QWEN.md

Example Memory File Content:

# My Coding Preferences

## Code Style
- Use TypeScript for all new JavaScript projects
- Prefer functional programming patterns
- Use const/let instead of var
- Always include error handling

## Project Context  
- This is a React application using Next.js
- We use Tailwind CSS for styling
- Database: PostgreSQL with Prisma ORM

## Personal Preferences
- Explain complex code with comments
- Write comprehensive unit tests
- Follow clean architecture principles

Usage:

• Create memory files using the /memory command or save_memory tool
• Files are automatically discovered and loaded during conversations
• Project-level files take priority over global files
• Multiple memory files can be active simultaneously

Session Commands

• /compress - Compress conversation history to continue within token limits
• /clear - Clear all conversation history and start fresh
• /stats - Check current token usage and limits

📝 Note: Session token limit applies to a single conversation, not cumulative API calls.
