Harrness

A CLI coding assistant powered by OpenRouter's LLM API.

Setup

pip install python-dotenv openrouter

Create a .env file with your API key:

OPENROUTER_API_KEY=your_api_key_here

Usage

python main.py

The assistant will prompt for input. Type your request and press Enter. The LLM can use three tools:

• read_file - Read a file's contents
• list_files - List files in a directory
• edit_file - Edit a file (replace text or create new files)

When the LLM needs a tool, it responds with:

tool: TOOL_NAME({"arg": "value"})

Tool results are fed back to the LLM for context.
