start-genai-backend skillB

start-genai-backend is agent-read markdown (skill) from arthur-ai/arthur-engine: Start the GenAI Engine backend server and frontend UI. Use when you need to launch the API server and the frontend locally..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Start GenAI Engine Backend Server

## Step 1 — GPT Key Gate

Use the Read tool to read `./genai-engine/.env`.

Check that `GENAI_ENGINE_OPENAI_GPT_NAMES_ENDPOINTS_KEYS` is present and has a non-empty value (not just `GENAI_ENGINE_OPENAI_GPT_NAMES_ENDPOINTS_KEYS=` with nothing after the `=`).

If the value is missing or empty:
- **STOP immediately. Do not proceed to Step 2.**
- Tell the user: "Setup cannot continue. Please open `genai-engine/.env` and set `GENAI_ENGINE_OPENAI_GPT_NAMES_ENDPOINTS_KEYS` using the format: `MODEL_NAME::ENDPOINT_URL::API_KEY` (e.g. `gpt-4o::https://api.openai.com/::sk-...`). Run the skill again once the key is set."

## Step 2 — Delegate Startup to Bash Sub-Agent

Only proceed here if Step 1 passed. Spawn a Task sub-agent with subagent_type="Bash" and the following self-contained prompt:

---
Start the GenAI Engine backend and frontend. Report success or failure for each step.

**Step 1 — Verify PostgreSQL is running:**
```bash
cd genai-engine && docker compose ps db
```
If not running or unhealthy, start it:
```bash
cd genai-engine && docker compose up -d db && sleep 3
```

**Step 2 — Start the backend server in the background:**
```bash
