SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill ensures the integrity of the ArenaMMO LobbyServer's authentication, matchmaking, and ticket issuance processes, maintaining security and compatibility.

Core Features & Use Cases

  • Authentication Invariants: Ensures that only the LobbyServer can issue signed AuthTickets, and credentials are verified securely.
  • Matchmaking Invariants: Manages player factions and queue operations with strict adherence to match size requirements.
  • Ticket Issuance Contract: Defines the structure and security requirements for AuthTickets to maintain compatibility and prevent unauthorized access.
  • Network & Security Guardrails: Implements flood defense, timeout handling, and login throttling to protect against attacks and maintain server stability.
  • Redis Pub/Sub Contract: Manages the communication between LobbyServer and GameServer through secure channels.

Quick Start

Use the lobbyserver-invariants skill to ensure compliance with the LobbyServer invariants during code updates or refactoring.

Frequently Asked Questions about lobbyserver-invariants

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I ensure secure authentication in multiplayer game server development?▼

Secure multiplayer authentication requires strict invariants, ensuring only the LobbyServer issues signed AuthTickets and verifies credentials safely. This prevents unauthorized access and maintains compatibility across the ArenaMMO environment.

What are the requirements for matchmaking queue operations in multiplayer games?▼

Matchmaking queue operations require managing player factions and strictly adhering to match size requirements. Following these invariants ensures fair and stable match assembly within the LobbyServer environment.

How does LobbyServer handle network security and flood defense?▼

Network security and flood defense are handled through timeout management, login throttling, and secure communication protocols. These guardrails protect the multiplayer server against attacks and maintain overall stability.

Can I use Redis Pub/Sub for LobbyServer and GameServer communication?▼

Yes, Redis Pub/Sub manages communication between the LobbyServer and GameServer through secure channels. This contract ensures reliable data exchange and maintains synchronization during multiplayer gameplay sessions.

Why does AuthTicket issuance require strict field ordering and random nonces?▼

AuthTicket issuance requires strict field ordering and random nonce generation to maintain structural compatibility and prevent unauthorized access. These security requirements ensure only valid, signed tickets are accepted.

When should I check LobbyServer invariants during game server updates?▼

You should check LobbyServer invariants during code updates or refactoring to ensure compliance with authentication, matchmaking, and ticket issuance rules. This preserves server stability and security integrity.
