+        The Unreal Engine SDK is documented on a SINGLE PAGE: docs-repo/docs/pages/client/sdk/unrealengine.md. Do NOT create new pages or subdirectories under client/sdk/.
+      docs-structure-desc: |
+        The site uses Vocs. Content lives in `docs-repo/docs/pages/`. Navigation is in `docs-repo/routes.ts`. SDK docs at `docs-repo/docs/pages/client/sdk/` are single `.md` files (bevy.md, javascript.md, unity.md, unrealengine.md, godot.md, rust.md, telegram.md), not subdirectories — the sole exception is `c/` which is a subdir.
