autoImage 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. Resolution logic is documented in SKILL.md's ## Image Generation Tools section.
