## Description

Generate or edit images and videos through the Atlas Cloud gateway. Use for Atlas-hosted Seedance 2.5/2.0, Gemini Omni Flash, MiniMax H3, Seedream 5.0, GPT Image 2, Nano Banana 2, or when one ATLASCLOUD_API_KEY should access multiple media model families.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Atlas Cloud

Route complete productions through `image_selector` or `video_selector`. Call
`atlas_image` or `atlas_video` directly when the user names Atlas Cloud or an
exact Atlas model. Never substitute a direct vendor endpoint for an Atlas request.

Set `ATLASCLOUD_API_KEY`. The aliases `ATLAS_CLOUD_API_KEY` and `ATLAS_API_KEY`
are accepted for compatibility.

## Preflight every paid call

1. Read `tool.get_info()["model_catalog"]`; do not infer availability from a
   search collection or invent a task suffix.
2. Select an exact model id and operation supported by that catalog.
3. Announce the Atlas tool, provider, exact model, request count, and estimated
   cost before submitting.
4. Use local-path inputs when convenient. The tool uploads them through Atlas.
5. Save outputs inside the active `projects/<project-id>/` tree and inspect them.

## Video routes

| Family | Operations | Exact route notes |
|---|---|---|
| Seedance 2.5 | text, image, reference | `bytedance/seedance-2.5/{text,image,reference}-to-video`; image mode uses `image` plus optional `last_image`; reference mode accepts up to 30 images, 10 videos, and 10 audios (including audio-only); 4, 30s; $0.134/s |
| Seedance 2.0 | text, image, reference | `bytedance/seedance-2.0/{text,image,reference}-to-video`; 4, 15s; $0.112/s |
| Gemini Omni Flash | text, image, reference, video edit | Standard routes use `google/gemini-omni-flash/...`; developer routes exist for text/image/reference only. Standard image mode uses one `image`; standard reference uses `images`; developer reference requires one `video_clips` object. |
| MiniMax H3 | text, image, reference | `minimax/h3/{text,image,reference}-to-video`; image mode supports optional `end_image`; reference mode requires `refers` objects; 4, 15s; 768P/2K; $0.10/s |
