---Field Reference
| Field | Type | Default | Description |
|---|---|---|---|
version |
int | 1 | Schema version |
preferred_layout |
string|null | null | Pre-selected layout — surfaces as the top recommendation in Step 3 |

preferred_image_backend |
string | auto |
Image backend selection. auto = prefer runtime-native tool, fall back to the only installed backend, ask if multiple non-native are present. ask = always confirm on every run. <backend-id> (e.g., codex-imagegen, baoyu-image-gen, image_generate) = pin this backend when available; fall back to auto when it isn't. Absent = auto. |
custom_styles |
array | [] | Additional styles available alongside the 21 built-ins |
Backend resolution logic is documented in the ## Image Generation Tools section of SKILL.md. This doc only defines the field.
All fields in this schema are defaults only — they shape Step-3 recommendations and Step-4 defaults but never bypass Step 4 confirmation (see the ## Confirmation Policy section in SKILL.md).
Example backend ids:
| Value | Meaning |
|---|---|
codex-imagegen |
Codex built-in imagegen tool |
baoyu-image-gen |
baoyu-image-gen skill / script backend |
image_generate |
Generic runtime image tool such as Hermes |
