Nano Banana Pro OpenRouter Adapter
This skill is a deterministic adapter around OpenRouter image generation. It is
intended for meta-skill skill_exec use, not as an open-ended agent surface.
Contract
- During MetaSkill execution, accepts only the parent-resolved, process-local
provider lease. The credential, endpoint, and proxy never enter
with, argv,
the plan, or persisted run data. Direct standalone CLI use may still provide
OPENROUTER_API_KEY.
- Does not read
.env files, prompt for credentials, print credentials, or
write credentials to disk.
- Uses only the model, base URL, output directory, and local path prefix passed
by the caller.
- Saves generated image bytes under the supplied output directory.
- Emits one
IMAGE_READY: JSON line per saved image.
- A missing/invalid required MetaSkill lease exits 78 before any provider
submission. Provider failures after submission emit
IMAGE_GENERATION_FAILED
with exit 0 so the webpage can bind a replacement slot without auto-replay.
Meta-Skill Payload Mode
When stdin is JSON containing media_slots, image_slots, slots, or
page_outline, the adapter generates image slots and preserves already
downloaded images. Structured slots are preferred over free-form outline text:
{
"requirement_framing": "...",
"media_slots": {"slots": [{"slot_id": "hero-visual", "modality": "image"}]},
"page_outline": "..."
