This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.8-flash on 10/20/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 3 test cases the skill fixed. Same model, same prompt, with and without the skill.
When validating a Godot 4 responsive HUD layout during development, what three fundamental aspect ratio / resolution categories should be tested at minimum to detect major layout breakages?
| Checked | Without skill | With skill |
|---|---|---|
| Recommends testing at the base design resolution. | Passed | Passed |
| Recommends testing at an ultrawide aspect ratio. | Passed | Passed |
| Recommends testing at a tall mobile portrait aspect ratio. | Missed | Passed |

All examples target Godot 4.3+ with no deprecated APIs. GDScript is shown first, then C#.

Configure base resolution and stretch behaviour in Project > Project Settings > Display > Window.
Key settings and their .godot/project.godot keys:
| Setting | project.godot key | Recommended value |
|---|---|---|
| Viewport width | window/size/viewport_width | 1920 (or your base design width) |
| Viewport height | window/size/viewport_height | 1080 (or your base design height) |
| Stretch mode | window/stretch/mode | canvas_items (most games) |
| Stretch aspect | window/stretch/aspect | expand (fill screen) or keep (letterbox) |
| Scale factor | window/stretch/scale | 1 (adjust for pixel art integer scaling) |
Godot 4.7+: Projects newly created in Godot 4.7 already default
display/window/stretch/modetocanvas_itemsanddisplay/window/stretch/aspecttoexpand(previouslydisabled/keep) — the recommendations above are now the out-of-the-box values. Projects created on older versions are unchanged (the property default is stilldisabled), so set both explicitly when upgrading. See the 4.7 migration guide.
These can also be set at runtime:
GDScript:
# Read current viewport size
var viewport_size: Vector2 = get_viewport().get_visible_rect().size
# Change stretch mode at runtime
ProjectSettings.set_setting("display/window/stretch/mode", "canvas_items")
C#:
// Read current viewport size
test cases passed, vs 20 / 23 without
