rconsole.* is a console-window library shipped by some executors. It opens a separate terminal window owned by the executor and exposes print, input, clear, and similar calls.
Hyperion (Roblox’s anticheat) detects it, and the implementation was unfinished - disabled for now. It’ll come back in the future. For script output use Roblox’s native
print and warn, which write to the Roblox client output console.
