+## Language Standards (load before writing code)
+
+| Language | When | Load |
+|----------|------|------|
+| GDScript (`.gd`) | Any GDScript authoring | `~/.claude/instructions/godot-code-standards.md` |
+| Rust (`.rs`) | Any `src/simulator/` work | `~/.claude/instructions/rust-code-standards.md` |
+| TypeScript (`.ts`, `.tsx`) | Any guide/package TS work | `~/.claude/instructions/typescript-code-standards.md` |
+| Python (`.py`) | Tools, scripts, data pipelines | `~/.claude/instructions/python-code-standards.md` |
+
+Hooks enforce these standards automatically on Write/Edit — they are not optional.

 ## Safety Rules
 - Never hardcode theme-specific strings in engine code
 - Never hardcode asset paths — always use `ThemeAssets.resolve()`
