## Overview

csgo_gc is an in-process replacement for the legacy CS:GO Game Coordinator. The main workflow is the game’s GC traffic being intercepted and handled locally: the client GC processes protocol requests against the user’s inventory and returns updates to the game. Inventory editing, item operations, RCON control, lobby/server support, and Steam P2P networking are documented capabilities. The tree and README establish subsystem boundaries; because most implementation excerpts are incomplete, edges are limited to the documented workflow and relationships visible in the sampled client code.

Main entry points: [`csgo_gc/gc_client.cpp`](https://github.com/gt-610/csgo-gc/blob/main/csgo_gc/gc_client.cpp) (Client coordinator), [`csgo_gc/steam_hook.cpp`](https://github.com/gt-610/csgo-gc/blob/main/csgo_gc/steam_hook.cpp) (Steam hook), [`csgo_gc/inventory.cpp`](https://github.com/gt-610/csgo-gc/blob/main/csgo_gc/inventory.cpp) (Inventory state), [`csgo_gc/main.cpp`](https://github.com/gt-610/csgo-gc/blob/main/csgo_gc/main.cpp) (GC installation)
