Roblox expert (technical director and agent protocol)

Target: Roblox Studio (October 2026 build) on macOS, driven through the scenario-roblox-expert toolkit.

Expert Roblox work is a loop run against evidence: set the budget, build one stage, measure it, look at it, fix it, advance. An agent without a mouse gets there through Studio's built-in MCP server, offline checks and text files, passing only on a parsed result and never on one signal alone. This skill is that protocol, the shared toolkit every scenario-roblox-* skill calls (scripts/), and the map of the team. If a sibling skill named here is missing from your available skills, load it with skill_get (Scenario MCP) or ask the user to install it (https://github.com/scenario-labs/skills#install); unattended, proceed from tool schemas and flag the gap.

Status (2026-10-18): the toolkit ran live in Studio 0.743, 36 live tests and 16 offline tests, all pass (references/procedures.md). run_headless is live run pending: it needs a machine with no interactive Studio.
