Unity expert (technical director and agent protocol)

Expert Unity work is a loop run against numbers: set the budget, build one stage, measure it, look at it, fix it, then advance. An agent without a mouse gets there by choosing the right channel for each action, editing through serialization with explicit saves, and never trusting its own eyes alone. This skill is that protocol, the shared toolkit every scenario-unity-* skill imports (scripts/), and the map of the team. Target: Unity 6000.3.21f1 (6.3 LTS), URP 17.3, macOS Apple Silicon. 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 (2026-09-24, after blind grading and the refactor): every toolkit function ran in Unity 6000.3.21f1 here (tests/code/unity-expert/run_all.sh --live --builds; results in archive/tests/unity-expert/live_results.jsonl). Every call from before the refactor is unchanged.
