CCS Installation Guide

Warning

Native shell installers (curl/irm) are deprecated. Use npm installation for all platforms. Legacy installers will be removed in v5.0.

npm Package Installation (Recommended)

Cross-Platform Installation

macOS / Linux / Windows

npm install -g @kaitranntt/ccs

Compatible with all package managers:

• npm install -g @kaitranntt/ccs
• yarn global add @kaitranntt/ccs
• pnpm add -g @kaitranntt/ccs
• bun add -g @kaitranntt/ccs

Benefits of npm installation:

• ✅ Cross-platform compatibility
• ✅ Automatic PATH configuration
• ✅ Auto-creates config files via postinstall script
• ✅ Easy updates: npm update -g @kaitranntt/ccs
• ✅ Clean uninstall: npm uninstall -g @kaitranntt/ccs
• ✅ Version pinning support
• ✅ Dependency management

What Happens During Install:

1. npm downloads and installs the package
2. Postinstall script automatically creates ~/.ccs/config.json and ~/.ccs/glm.settings.json
3. npm creates ccs command in your PATH

Note: If you use npm install --ignore-scripts, config files won't be created. Run without that flag:

npm install -g @kaitranntt/ccs --force

[!] DEPRECATED: One-Liner Installation (Legacy)

Warning

These installers are deprecated and will be removed in v5.0. They now auto-redirect to npm installation. Please use npm directly.

macOS / Linux

# Short URL (via CloudFlare)
curl -fsSL ccs.kaitran.ca/install | bash

# Or direct from GitHub
curl -fsSL https://raw.githubusercontent.com/kaitranntt/ccs/main/installers/install.sh | bash

Note: Scripts show deprecation warning and automatically run npm installation if Node.js is available.

Windows PowerShell

# Short URL (via CloudFlare)
irm ccs.kaitran.ca/install.ps1 | iex

# Or direct from GitHub
irm https://raw.githubusercontent.com/kaitranntt/ccs/main/installers/install.ps1 | iex

Note: Scripts show deprecation warning and automatically run npm installation if Node.js is available.

[!] DEPRECATED: Git Clone Installation (Legacy)

Warning

Git clone installation is deprecated. Use npm installation instead.

macOS / Linux

git clone https://github.com/kaitranntt/ccs.git
cd ccs
./installers/install.sh

Windows PowerShell

git clone https://github.com/kaitranntt/ccs.git
cd ccs
.\installers\install.ps1

Note: Scripts show deprecation warning and automatically run npm installation if Node.js is available.

Manual Installation

macOS / Linux

# Create directory
mkdir -p ~/.local/bin

# Download script
curl -fsSL https://raw.githubusercontent.com/kaitranntt/ccs/main/ccs -o ~/.local/bin/ccs
chmod +x ~/.local/bin/ccs

# Add to PATH (choose your shell)
# For bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

# For zsh
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

# For fish
echo 'set -gx PATH $HOME/.local/bin $PATH' >> ~/.config/fish/config.fish

Windows PowerShell

# Create directory
New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.ccs"

# Download script
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/kaitranntt/ccs/main/ccs.ps1" -OutFile "$env:USERPROFILE\.ccs\ccs.ps1"

# Add to PATH (restart terminal after)
$Path = [Environment]::GetEnvironmentVariable("Path", "User")
[Environment]::SetEnvironmentVariable("Path", "$Path;$env:USERPROFILE\.ccs", "User")

What Gets Installed

Executable Location:

• macOS / Linux: ~/.local/bin/ccs (symlink to ~/.ccs/ccs)
• Windows: %USERPROFILE%\.ccs\ccs.ps1

Configuration Directory (~/.ccs/):

~/.ccs/
├── ccs                     # Main executable (symlink target)
├── config.json             # Profile configuration
├── config.json.backup      # Single backup (overwrites each install)
├── glm.settings.json       # GLM profile
├── VERSION                 # Version file
├── uninstall.sh            # Uninstaller
└── .claude/                # Claude Code integration
    ├── commands/ccs.md     # /ccs meta-command
    └── skills/             # Delegation skills

Upgrade CCS

macOS / Linux

# From git clone
cd ccs && git pull && ./install.sh

# From curl install
curl -fsSL ccs.kaitran.ca/install | bash

Windows PowerShell

# From git clone
cd ccs
git pull
.\install.ps1

# From irm install
irm ccs.kaitran.ca/install.ps1 | iex

Auto PATH Configuration

The installer automatically configures your shell PATH:

Supported Shells:

• bash (.bashrc or .bash_profile)
• zsh (.zshrc)
• fish (.config/fish/config.fish)

How It Works:

1. Detects your current shell from $SHELL environment variable
2. Checks if ~/.local/bin already in PATH
3. If not, adds appropriate export to shell profile
4. Shows reload instructions

Idempotent:

• Safe to run multiple times
• Checks for existing CCS PATH entry before adding
• Won't create duplicate entries

Manual PATH Setup (if auto-config fails):

Bash/Zsh:

echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc  # or ~/.zshrc
source ~/.bashrc  # or source ~/.zshrc

Fish:

echo 'set -gx PATH $HOME/.local/bin $PATH' >> ~/.config/fish/config.fish

Requirements

macOS / Linux

• bash 3.2+
• jq (JSON processor, optional for enhanced features)
• Claude CLI

Windows

• PowerShell 5.1+ (pre-installed on Windows 10+)
• Claude CLI

Installing jq (macOS / Linux, optional)

# macOS
brew install jq

# Ubuntu/Debian
sudo apt install jq

# Fedora
sudo dnf install jq

# Arch
sudo pacman -S jq

Note:

• jq enhances GLM profile creation but is not required
• Windows uses PowerShell's built-in JSON support - no jq needed
• Installer creates basic templates without jq
