Installation

pip install quasar-ai

Setup API Keys

IMPORTANT: You must provide your own API keys. QUASAR does not include any API keys.

Option 1: Using .env file (Recommended)

Create a .env file in your project directory:

# Groq (recommended - fast inference)
GROQ_API_KEY_1=gsk_your_key_here
GROQ_API_KEY_2=gsk_your_second_key_here

# Cerebras
CEREBRAS_API_KEY_1=csk_your_key_here
CEREBRAS_API_KEY_2=csk_your_second_key_here

# Ollama runs locally - no API key needed
# Default: http://localhost:11434

# Web Search (optional but recommended)
# QUASAR has multiple web tools with fallback support
# Get free key at: https://tavily.com
TAVILY_API_KEY=tvly_your_key_here

Option 2: Using Environment Variables

# Groq
export GROQ_API_KEY_1="gsk_your_key_here"
export GROQ_API_KEY_2="gsk_your_second_key_here"

# Cerebras
export CEREBRAS_API_KEY_1="csk_your_key_here"

Multiple Keys

You can add multiple keys per provider (e.g., GROQ_API_KEY_1, GROQ_API_KEY_2, GROQ_API_KEY_3). If a key hits rate limits, QUASAR automatically rotates to the next available key.

• Groq: https://console.groq.com
• Cerebras: https://cloud.cerebras.ai

Usage

Interactive Mode (REPL)

quasar
# or
quasar --interactive

Single Command

quasar "create a hello.py file that prints Hello World"
quasar "explain main.py"
quasar "fix the bug in utils.py"
quasar "list files in current directory"

Specify Workspace

quasar --workspace /path/to/project "add tests for api.py"

Custom Model Selection

By default, QUASAR automatically selects the best model. You can override with --model:

quasar --model cerebras/qwen-3-32b "explain this code"
quasar --model groq/llama-3.3-70b-versatile "create a REST API"
quasar --model ollama/qwen2.5-coder:7b "fix the bug"

Project Configuration (.quasar/)

On first run, QUASAR creates a .quasar/ directory in your workspace with project-specific configuration:

.quasar/
├── context.md    # Your project rules & preferences
├── memory.json   # Session history & recent files
├── mcp.json      # MCP server configuration
├── hooks/        # Custom lifecycle hooks (templates provided)
└── backups/      # Automatic file backups

context.md

Customize QUASAR's behavior for your project by editing .quasar/context.md:

• Project Description: Help QUASAR understand your project goals
• Code Style: Your preferred conventions (type hints, naming, etc.)
• Important Files: Key files QUASAR should be aware of
• Project Rules: Custom rules for QUASAR to follow

hooks/

Add custom Python hooks to control QUASAR's behavior:

• PRE_TOOL_USE: Run before any tool execution
• POST_TOOL_USE: Run after tool execution
• ON_COMPLETE: Run when task completes

Templates are provided in .quasar/hooks/ - rename .template files to .py to activate.

mcp.json

QUASAR supports Model Context Protocol (MCP) for extending tool capabilities with external servers.

{
  "mcpServers": {
    "my-server": {
      "command": ["python", "my_mcp_server.py"],
      "description": "Custom MCP server"
    }
  }
}

Backup & Recovery

QUASAR automatically backs up files before modifying or deleting them.

• Location: .quasar/backups/
• Auto-cleanup: Last 50 backups kept
• Restore: Ask QUASAR to "list backups" or "restore backup"

Security

QUASAR blocks access to sensitive files:

• .env files (all variants)
• SSH keys (.ssh/id_rsa, etc.)
• AWS credentials (.aws/credentials)
• Certificates (.pem, .key, .p12, .pfx)

Updating

pip install --upgrade quasar-ai
