TDQS
Scored across 14 tools
Each tool has a clearly distinct purpose: navigation (get_children, get_descendants), property access/modification (get_properties, set_properties), instance lifecycle (create, delete, clone, move), selection (get_selection, set_selection), service handling (get_services, insert_service), and script execution (execute_luau). Even the related get_services and insert_service are distinguished by scope (list all vs. get/create one).
All tools follow a consistent verb_noun pattern in snake_case: get_, set_, create_, delete_, clone_, move_, insert_, execute_, find_. The naming is predictable and uniform across the entire set.
14 tools is well within the ideal 3-15 range. Each tool covers a specific operation without redundancy, making the set concise but comprehensive for interacting with Roblox Studio.
The tool surface covers the full lifecycle of instance manipulation (create, read, update, delete, clone, move), hierarchy traversal, selection, service access, and arbitrary Lua execution for advanced operations. No critical gaps are apparent for the stated purpose of bridging Roblox Studio.
