qwen3-coder-agent 0.1.1

A terminal-based agent for interacting with Qwen3-Coder models

Qwen3-Coder Terminal Agent

A powerful terminal interface for interacting with the Qwen3-Coder model, featuring secure API key management, hybrid token counting, and intelligent rate limiting.

Features

• Hybrid Token Counting: Combines local estimation with API validation for accurate token counting
• Secure API Key Management: Environment-based configuration with secure storage
• Adaptive Rate Limiting: Intelligent handling of rate limits with predictive throttling
• Context Management: Dynamic windowing for large conversations
• Terminal UX: Clean interface with real-time token usage
• Session Persistence: Save and load conversation history

Installation

Option 1: Install from PyPI (recommended)

pip install qwen3-coder-agent

Option 2: Install from source

1. Clone the repository:

   git clone https://github.com/qaaph-zyld/qwen3-coder_cli.git
   cd qwen3-coder_cli
   

2. Create and activate a virtual environment (recommended):

   python -m venv venv
   # On Windows:
   venv\Scripts\activate
   # On macOS/Linux:
   source venv/bin/activate
   

3. Install the package in development mode:

   pip install -e .
   

Configuration

Create a .env file in your project directory with your API configuration:

QWEN_API_KEY=your_api_key_here
QWEN_API_BASE=https://api.qwen.com/v1  # Default value, update if different
MAX_CONTEXT_TOKENS=4000  # Adjust based on your model's context window

Security

API Key Management

• Never commit your API key to version control
• The .env file is included in .gitignore to prevent accidental commits
• For production use, consider using a secure secret management solution

Token Security

• API keys and tokens are only sent to the Qwen3 API endpoint
• All API communications are encrypted with HTTPS
• Token usage is tracked locally but never stored with the conversation history

Best Practices

1. Rotate your API keys regularly
2. Use the principle of least privilege when generating API keys
3. Monitor your API usage for any unexpected activity
