Generate quizzes and manage multiplayer contests with Mistral and Supabase

Description

Quick overview
This workflow powers MindArena’s quiz features by generating and retrieving quizzes in Supabase, managing multiplayer contest rooms via a single webhook, and producing personalized quiz-performance feedback using Mistral Cloud.

How it works
Receives a POST request to /webhook/generate-quiz, sends the topic, difficulty, and question count to Mistral Cloud to generate multiple-choice questions, and stores the quiz and questions in Supabase before returning the quiz_id.
Receives a request to /webhook/get-quiz, fetches the quiz and its questions from Supabase by quiz_id, and returns a combined JSON payload to the client.
Receives a POST request to /webhook/ai-feedback, sends the submitted quiz performance data to Mistral Cloud via an AI Agent to generate structured tutoring feedback.
Parses the AI output into overall_performance, strengths, areas_to_improve, and practical_suggestion, falling back to default feedback when the AI returns invalid JSON.
Receives a POST request to /webhook/arena-management, routes by action, and uses Supabase to create rooms (including generating quiz questions), join rooms, start contests, fetch contest questions, submit scored results, and return a ranked leaderboard.

Setup
Add a Supabase API credential and ensure your Supabase project has the required tables (at minimum: quizzes, questions, rooms, room_players, and contest_results).
Add a Mistral Cloud API credential for the Mistral chat model used for quiz generation and performance feedback.
Deploy the workflow and configure your frontend to call the webhook endpoints (/webhook/generate-quiz, /webhook/get-quiz, /webhook/ai-feedback, and /webhook/arena-management) with the expected JSON fields such as quiz_id, action, and room/answer payloads.
For the arena flow, generate a quiz first (or pass a valid quiz_id) before calling startContest, and ensure createRoom includes valid max_players (2–10) and number_of_questions.
