Blackbox Code

Key Features

• Code Understanding & Editing - Query and edit large codebases beyond traditional context window limits
• Workflow Automation - Automate operational tasks like handling pull requests and complex rebases
• Enhanced Parser - Adapted parser specifically optimized for BlackboxAI models
• Vision Model Support - Automatically detect images in your input and seamlessly switch to vision-capable models for multimodal analysis

Installation

Prerequisites

Ensure you have Node.js version 20 or higher installed.

curl -qL https://www.npmjs.com/install.sh | sh

Install from source

git clone https://github.com/blackboxaicode/cli.git
cd cli
npm install
npm install -g .

Quick Start

# Start Blackbox Code
blackbox

# 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 .blackboxcli/settings.json in your home directory:

{
  "sessionTokenLimit": 32000
}

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.

Vision Model Configuration

Blackbox Code includes intelligent vision model auto-switching that detects images in your input and can automatically switch to vision-capable models for multimodal analysis. This feature is enabled by default - when you include images in your queries, you'll see a dialog asking how you'd like to handle the vision model switch.

Skip the Switch Dialog (Optional)

If you don't want to see the interactive dialog each time, configure the default behavior in your .blackboxcli/settings.json:

{
  "experimental": {
    "vlmSwitchMode": "once"
  }
}

Available modes:

• "once" - Switch to vision model for this query only, then revert
• "session" - Switch to vision model for the entire session
• "persist" - Continue with current model (no switching)
• Not set - Show interactive dialog each time (default)

Disable Vision Models (Optional)

To completely disable vision model support, add to your .blackboxcli/settings.json:

{
  "experimental": {
    "visionModelPreview": false
  }
}

Tip: In YOLO mode (--yolo), vision switching happens automatically without prompts when images are detected.

Authorization

API Key Authentication

For programmatic access or advanced use cases, you can authenticate using an API key:

Getting Your API Key:

1. Navigate to the API Keys section of your BLACKBOX dashboard
2. Your API key will be displayed on this page
3. Click the copy icon to copy the key to your clipboard
4. Run blackbox configure and you will be able to set the key

Important: Treat your API key like a password! Do not share it publicly or commit it to version control.

Usage Examples
