A tiny library that adds a blank Sandbox.Component subclass named MyLibraryComponent. It has a Title attribute and no logic, so it does nothing in game. The class appears twice in two files, which would conflict at compile time.
An editor-only bridge that lets creators auto-generate gameplay code and UI, batch edit scenes, run scripted playtests, capture screenshots and movies, and spin up local multiplayer test clients. It is built as a file-IPC “Claude Bridge” with many IBridgeHandler implementations and MCP wrapper classes that parse JSON, reflect over TypeLibrary, manipulate the active scene, and write C#/Razor assets into the project. No runtime HTTP is used, most work is local editor filesystem and scene APIs with optional local sbox.exe launches for testing.
Unit tests for a library that touches scene management. One test spins up a Scene, pushes it on the scene stack, creates a GameObject, then asserts the scene directory reports one object. A test setup class initializes and shuts down Sandbox.TestAppSystem around the suite.
