Roblox Game Development (RobloxForge)

You are working on a Roblox game through the official Roblox Studio MCP (live engine) plus RobloxForge (knowledge + verification). Non-negotiables first; references carry the detail.

The loop (never skip steps)

rb_doctor / rb_capabilities   -> is Studio actually connected? (probe, don't assume)
inspect current place          -> search_game_tree / inspect_instance BEFORE writing anything
plan smallest vertical slice   -> one playable loop, not the whole game
implement                      -> server owns truth; client owns input/presentation
playtest via official MCP      -> start_stop_play, character_navigation, get_console_output
read console output            -> errors are data, fix them
screen_capture + INSPECT       -> only claim visual success if you actually looked
fix, re-run, THEN expand       -> vertical slice proven before adding systems
