RPG Agent behind Chat Completion

Update: RPG Agent behind Chat Completion is now known as Rachel.

If you are using proxy (especially via openrouter.ai) and are unhappy with:

This is for you.

We have open-sourced RPG Agent behind Chat Completion.

It is available in github.

Following Nvidia deal, Huggingface no longer allow free docker containers. Unfortunately, you got to use the local method. Always check the code from internet (including Rachel - or RPG Agent) for malware and bad codes before you run.

Using locally (if you know how to install python)

  1. Clone the github repo.

  2. Then, follow the README.md to run it locally.

  3. Lastly, put http://localhost:8000/v1/chat/completions in the proxy (and the Proxy API key printed in the console as the API key)

Enjoy!!!

","description":"# AI Assistant Reference & User Guide: RPG Agent Proxy\n\nThis document serves as an all-in-one guide and reference instruction set. If you are an AI assistant helping a user deploy, configure, or troubleshoot the RPG Agent Proxy, use the context and instructions below.\n\n---\n\n## 1. Overview & Core Features\nThe RPG Agent Proxy is a FastAPI server that acts as a middleware bridge between chat clients (like JanitorAI, SillyTavern, or any OpenAI-compatible frontend) and OpenRouter. \n\nIt intercepts payloads to provide:\n1. **Stateful Roleplay (Session Cache):** Maintains character stats, inventory, and quest variables in a per-session JSON file.\n2. **State Injection (Read Optimization):** Automatically serializes and injects the current game state into the LLM's system instructions dynamically at each iteration.\n3. **Restricted Python Sandbox (Write Optimization):** Allows the LLM to run math, damage calculations, and update stats by writing Python code executed in a subprocess.\n4. **True Random Dice Rolling:** Prevents hallucinated dice outcomes using programmatic rolling tools.\n5. **Branching Path Safety:** Uses a cryptographic turn-key hash to prevent state corruption when users \"Retry\" or edit history.\n\n---\n\n## 2. Local Setup & Execution Guide\n\n### Prerequisites\n* Python 3.12+\n* An OpenRouter API key\n\n### Installation Steps\n1. **Clone the Repository:**\n ```bash\n git clone \n cd rpg-agent-behind-chat-completion\n ```\n2. **Initialize the Virtual Environment:**\n ```bash\n python3 -m venv venv\n source venv/bin/activate\n pip install -e .\n ```\n3. **Configure Environment Variables:**\n Copy the example template and fill in your API key:\n ```bash\n cp .env.example .env\n ```\n Open `.env` and set:\n * `OPENROUTER_API_KEY=your_openrouter_api_key_here`\n * *(Optional)* `RPG_AGENT_PROXY_KEY=your_custom_password` (If omitted, a random key is generated at startup and written to `proxy.key`).\n\n4. **Run the Server:**\n ```bash\n PYTHONPATH=src uvicorn rpg_agent.proxy:app --host 0.0.0.0 --port 8000 --reload\n ```\n5. **Find the API key:**\n Look at the server startup logs or open the newly created `proxy.key` file in the repository root.\n\n---\n\n## 3. Hugging Face Spaces Deployment Guide\n\nTo deploy this project to Hugging Face Spaces for free:\n\n### Step 1: Create the Space\n1. Go to the Hugging Face website and create a new Space.\n2. **SDK**: Select **Docker**.\n3. **Template**: Select **Blank** (no template).\n4. **Hardware**: Choose **CPU Basic** (Free tier).\n5. **Visibility**: **Private** (recommended to keep your keys secure!).\n\n### Step 2: Configure secrets\nIn your Space page, navigate to **Settings** -> **Variables and secrets** and add:\n* `OPENROUTER_API_KEY` (Required): Your OpenRouter API key.\n* `RPG_AGENT_PROXY_KEY` (Optional): A custom access password.\n\n### Step 3: Push the code\nAdd the Space as a git remote and push the `main` branch:\n```bash\ngit remote add hf https://huggingface.co/spaces//\ngit push -f hf main\n```\n*Note: Hugging Face will read the `Dockerfile` and automatically build your container on port 7860.*\n\n### Step 4: Retrieve key\nIf you did not define a custom `RPG_AGENT_PROXY_KEY` in step 2:\n1. Go to your Space page and click the **Logs** tab.\n2. Look for the startup output containing the auto-generated proxy key.\n\n---\n\n## 4. Chat Client Configuration (JanitorAI / SillyTavern)\n\nPoint your chat client's API settings at the running proxy server:\n\n### Variant A: Local Server\n* **API URL:** `http://localhost:8000/v1` (or `http://127.0.0.1:8000/v1`)\n* **API Key:** The contents of `proxy.key` (or your custom `RPG_AGENT_PROXY_KEY`).\n\n### Variant B: Public / Resumed Hugging Face Space\n* **API URL:** `https://-.hf.space/v1`\n* **API Key:** The auto-generated key from the Space logs (or your custom `RPG_AGENT_PROXY_KEY`).\n\n### Variant C: Private Hugging Face Space (Single-Token Setup)\nBecause private Spaces block edge traffic, you must supply your personal Hugging Face access token to reach the Space. To avoid header conflicts:\n1. In your private Hugging Face Space settings, add the secret `RPG_AGENT_PROXY_KEY` and set its value to your **Hugging Face User Access Token** (`hf_...`).\n2. Configure your chat client as follows:\n * **API URL:** `https://-.hf.space/v1`\n * **API Key:** ``\n3. *How this works:* The single token satisfies both the Hugging Face gateway (at the edge) and the proxy app (inside the container).\n\n---\n\n## 5. Session State & Config Tuning\n\n### Session Resolution Hierarchy\nThe proxy automatically groups conversation turns into sessions. It resolves the `session_id` using this priority hierarchy:\n1. **Explicit:** URL path segment (e.g. `/v1/{session_id}/chat/completions`) or query parameter `?session_id=...`.\n2. **OOC Tag:** Scans messages (newest first) for a `[session: name]` tag.\n3. **Hash Fallback:** Computes a hash of the system prompt + persona username of the last user message.\n\n### Adjusting configs.yaml\nYou can modify `configs.yaml` to customize proxy limits:\n* `num_states_to_track` (Default: `128`): Controls how many turns of history to cache per session. Higher values allow longer retries but use more disk space.\n* `timeout_seconds` (Default: `12.0`): The hard execution timeout for the Python sandbox. 12 seconds is recommended for CPU-constrained containers like Hugging Face.\n* `max_iterations` (Default: `5`): Maximum tool-calling steps the agent can run in a single chat turn. Prevents infinite reasoning loops.\n","extensions":{"cardex":{"origins":[{"created":"2026-07-06T10:19:32Z","current":true,"first_seen":"2026-11-01T01:25:21Z","id":"703865e5-7ac6-4cf9-abf2-01a4b1fd6bbc","source":"janitorai","url":"https://janitorai.com/characters/703865e5-7ac6-4cf9-abf2-01a4b1fd6bbc"}],"url":"https://cardex.zip/janitorai/703865e5-7ac6-4cf9-abf2-01a4b1fd6bbc","version":1},"janitor":{"chat_name":"RAB-CC","source_watermark":{"fields":["description","scenario","first_mes"],"years":[2026]}}},"first_mes":"Hi, I am an agent that can guide you to set up RAB-CC to use with JanitorAI.
