Unity pack

Default upstream: CoplayDev/unity-mcp. The IvanMurzak implementation remains a selectable inactive alternative.

codex plugin add ai-game-studio-unity@frabcd-ai-game-studio

The setup skill detects ProjectVersion.txt, package state, installed editors, OS boundary, and existing MCP conflicts. It plans a pinned server plus editor companion, discloses process/network/project-write permissions, and validates compilation, connection, tests, and a screenshot after confirmation. Disable stops the adapter; rollback restores Codex and Unity package/config backups.

Exact pins and commands live in the pack descriptor shipped with the plugin.
