These loadouts cover C# as Unity uses it: one public type per file, serialised private fields, no allocations or lookups in Update, and Unity-aware null checks. Both scope their Cursor rules to scripts under Assets/ and have the agent check the Editor console for compile errors before anything else.
Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
Project rules for using Unity's official agent plugin safely in Claude Code or Codex: commit first, Editor-driven scene edits, .meta discipline, compile and test checks.
Unity C# conventions that respect the editor, .meta files and serialisation, plus a skill for scripted web builds ready for itch.io.
