bba-chat

Ask AI backend for the Big Brain Ape dashboard. The live Space is simzy-bba-chat.hf.space (Simzy/bba-chat).

The dashboard posts a question and polls this inbox for a role=agent reply. This server stores those messages and, after each POST /send, asks a Virtuals GAME ChatAgent that speaks as Big Brain Ape / BigBrain2Bot (Virtuals agent #96114, DegenClaw #1729).

@BigBrain2Bot on Telegram stays on Virtuals. This Space does not register a Telegram webhook.

How Ask AI uses it

The dashboard (app35.html) does this:

1. POST /send with {"text": "...", "user": "analysis-app"}.
2. Poll GET /messages?since=<user message ts> about every 4 seconds, for up to 120 seconds.
3. Render the first role=agent message whose ts is greater than that user timestamp.

The tasks page uses the same inbox with user: "Simzy".

Agent replies are produced by game-sdk 0.1.5:

from game_sdk.game.chat_agent import Chat, ChatAgent

agent = ChatAgent(api_key=os.environ["GAME_API_KEY"], prompt=AGENT_PROMPT)
chat = agent.create_chat(partner_id=user, partner_name=user)
response = chat.next(user_text)  # response.message is stored as role=agent

ChatAgent lives in game_sdk.game.chat_agent (not game_sdk.game.agent). The published 0.1.5 wheel includes that module. The key must start with apt- or the SDK raises before any call.

Sessions are per user. The SDK has no save/resume helper, so this app stores conversation_id in $BBA_CHAT_DATA/sessions.json and rebuilds Chat(conversation_id, client) for the next turn. If a conversation is finished or the next call fails, the id is dropped and create_chat runs again.

The Ask AI page hides agent text that contains telegram, on it, get back to you, or I'll review. GAME replies are rewritten so those phrases do not swallow the answer. POST /respond text is stored as sent.

HTTP contract

Method	Path	Body / query	Notes
GET	/		Health plus message count and whether GAME_API_KEY is set
GET	/health		Same booleans as /
GET	/messages	since (unix seconds, default 0)	{"messages": [...], "total": N}
POST	/send	{"text", "user"}	Stores role=user, then replies in the background
POST	/respond	{"text", "secret"}	Manual role=agent write. Does not call GAME
GET	/pending	secret	User messages after the latest agent message

User message shape: id, ts, role (user), text, user.

Agent message shape: id, ts, role (agent), text.

/ and /health include game_api_key_set and game_api_key_v2 (true only when the key starts with apt-). They never return the key.

Without GAME_API_KEY, /send still returns immediately and stores an agent message that says the key is not configured. A key that does not start with apt- stores that error instead of raising.

Secrets Casey must set on the Space

In the Space: Settings → Variables and secrets → New secret.

Secret	Required	Purpose
GAME_API_KEY	Yes, for live replies	Virtuals GAME v2 key. Must start with apt-. From the GAME console.
BBA_CHAT_SECRET	Recommended	Protects POST /respond and GET /pending. If unset, the process falls back to bba-chat-2026.

Do not put either value in the Dockerfile or the repo. The image only sets BBA_CHAT_DATA=/data.

Optional runtime setting (not a secret): BBA_CHAT_GAME_TIMEOUT seconds for the GAME HTTP calls. Default 75, clamped to 10–110 so a failure still lands inside the dashboard's 120 second poll.

After saving secrets, restart the Space so the container sees them.

Health check

curl -s https://simzy-bba-chat.hf.space/health

Expect "status": "ok" and "game_api_key_set": true once the secret is present. Then:

curl -s -X POST https://simzy-bba-chat.hf.space/send \
  -H 'Content-Type: application/json' \
  -d '{"text":"What are the three lenses?","user":"casey"}'
curl -s 'https://simzy-bba-chat.hf.space/messages?since=0'

A GAME reply usually shows up within 30–90 seconds. If the key is missing, the agent error row is written as soon as the background task runs.

Run locally

pip install -r requirements.txt
export BBA_CHAT_DATA=/tmp/bba-chat
export GAME_API_KEY=apt-your-key
export BBA_CHAT_SECRET=choose-a-secret
python app.py

The process listens on 0.0.0.0:7860. Messages go to $BBA_CHAT_DATA/messages.json. chat.json in this repo is the old stub and is not the live store.

Deploy

This repo is the Space source: Dockerfile, app.py, requirements.txt. Point the Hugging Face Space at this repo, or copy these files into Simzy/bba-chat, then set the secrets above and rebuild. Rebuilding without GAME_API_KEY keeps the inbox up and stores the not-configured agent message.
