Most editor integrations stop at reading and writing the place file; this one attaches to the running game. Luau can be evaluated inside a live server or client peer sharing the same require cache as the game's own scripts, breakpoints record each hit without pausing the session, and solo or multi-client playtests are started and stopped as tools. For performance work it captures script and micro profiler timings, breaks down memory, and analyses scene cost per peer. Creator Store insertion is handled carefully: an asset is previewed with its security scan, then stripped of scripts and package links and verified before being parented. A read-only inspector build exists for teams that will not allow DataModel writes.
