Installation

1. Clone and build:

git clone <your-repo-url>
cd anthropic-cli
go build -o klod

2. Create a symlink for global access:

sudo ln -s $(pwd)/klod /usr/local/bin/klod

Or install via Go:

go install

Configuration

The tool looks for configuration files in the following order:

1. ~/.config/klod/config (XDG standard location)
2. ~/.klod.env (home directory)
3. .env in the current directory (for project-specific overrides)

Setup your config:

# Create the config directory
mkdir -p ~/.config/klod

# Create config file
cat > ~/.config/klod/config << EOF
ANTHROPIC_API_KEY=your-api-key-here
MODEL=claude-sonnet-4-5-20250929
SYSTEM_PROMPT=
EOF

Configuration options:

• ANTHROPIC_API_KEY (required): Your Anthropic API key
• MODEL (optional): Model to use (default: claude-sonnet-4-5-20250929)
• SYSTEM_PROMPT (optional): Custom system prompt for Claude

Usage

Start a conversation:

klod "Hello, how are you?"

This will:

1. Send your initial message to Claude
2. Stream the response in real-time
3. Enter an interactive chat mode where you can continue the conversation

Type exit or quit to end the conversation.

Examples

# Ask a quick question
klod "What is the capital of France?"

# Start a coding session
klod "Help me write a Python function to calculate fibonacci numbers"

# Use a different model (set in config)
# Edit your config file and change MODEL=claude-opus-4-5-20251101
klod "Explain quantum computing"
