What is Faucet-Lobby CLAUDE.md?

A project guide for Faucet Lobby, a Python service that helps game servers announce themselves and lets players find available servers. It supports older and newer network protocols and removes servers that stop renewing their registration.

Use it when changing server registration, expiration, server-list queries, Gang Garrison 2 compatibility, or the web-based server list.

It clarifies how servers register, how clients search, and how expired entries are removed, which helps preserve compatibility between protocol handlers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00585	$0.00585
Opus 5.5	$0.00234	$0.00234
Sonnet 5.5	$0.00117	$0.00117

Security

Grade A, and why

Faucet-Lobby CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This is the Faucet Lobby - a game server lobby system originally created for Gang Garrison 2 but designed to be more generic. It's a Python-based server discovery system that allows game servers to register themselves and clients to query for available servers.

Architecture

The system consists of several key components:

Core Server Management (lobby.py):

GameServer class: Represents individual game servers with metadata (name, players, bots, maps, etc.)
GameServerList class: Manages server registration, expiration, and lookup using an expiration set
Servers auto-expire after 70 seconds unless re-registered every ~30 seconds

Protocol Handlers:

GG2LobbyRegV1: Legacy UDP registration protocol for Gang Garrison 2 servers
NewStyleReg: Modern UDP registration protocol supporting new-style server data
GG2LobbyQueryV1: Legacy TCP query protocol for client requests
NewStyleList: Modern TCP query protocol with structured server data

Web Interface (weblist.py):

LobbyStatusResource: HTTP interface showing active servers in browser-friendly format
Serves at port 29950 with status page at /status

Utilities:

expirationset.py: Time-based expiration tracking for server entries
ordereddict.py: Ordered dictionary implementation for Python compatibility

Network Ports:

29942: Legacy GG2 registration (UDP) and query (TCP)
29944: New-style registration (UDP) and query (TCP)
29950: Web interface (HTTP)

Protocol Support

The lobby supports both legacy Gang Garrison 2 protocols and a newer generic protocol defined in "Protocol Spec.txt". The newer protocol uses UUIDs for lobby identification and supports IPv6, structured key-value metadata, and better extensibility.

Running the Server

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Faucet-Lobby CLAUDE.md is an instructions file published in the GitHub repository Medo42/Faucet-Lobby (5 stars, last pushed 1y ago), licensed ISC. It adds 585 tokens to every session, about $0.0023 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
