RACHEL (rachel-proxy)

RACHEL (Rpg Agent CHat Evaluation Loop) is an Agentic Harness Middleware that sits between an OpenAI-compatible chat client front-end (such as Janitor AI, Wyvern Chat etc.) and LLM completion providers (OpenRouter, OpenAI, Google Gemini, DeepSeek), running request payloads through a stateful LangGraph agent with a secure V8 code sandbox containing dice and contest RNG helper functions.

💻 Developer Setup

If you are cloning this repository for local development:

1. Install Python dependencies:

   pip install -e ".[dev]"
   

2. Build Frontend Assets (Required): The compiled static frontend directory (src/rachel/static/) is git-ignored. You MUST build the frontend before launching the backend server:

   python scripts/build_frontend.py --target local
   

3. Run the Server:

   uvicorn rachel.proxy:app --reload --host 0.0.0.0 --port 8000
   

4. Run Tests with Coverage: Ensure your code changes pass all tests and maintain at least 75% coverage:

   pytest --cov=src --cov-fail-under=75
   

Initial Setup & LLM Provider Credentials

Once the proxy starts, open the Admin Console in your browser at http://localhost:8000:

1. Proxy API Key: Enter the local admin key (printed to console logs or saved in data/proxy.key).
2. Provider Credentials: Configure your preferred provider (OpenRouter BYOK / PKCE, OpenAI, Google Gemini, or DeepSeek) directly in the Provider Credentials card.
3. Select your Active Provider and save settings.
