atlas-cloud skill
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.

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.
git clone --depth 1 https://github.com/OpenMontageInc/OpenMontage.git /tmp/OpenMontage mkdir -p ~/.claude/skills cp -r /tmp/OpenMontage/.agents/skills/atlas-cloud ~/.claude/skills/atlas-cloud

Atlas Cloud
Route complete productions through imageselector or videoselector. Call atlasimage or atlasvideo directly when the user names Atlas Cloud or an exact Atlas model. Never substitute a direct vendor endpoint for an Atlas request.
Set ATLASCLOUDAPIKEY. The aliases ATLASCLOUDAPIKEY and ATLASAPI_KEY are accepted for compatibility.
Preflight every paid call
search collection or invent a task suffix.
- Read tool.getinfo()["modelcatalog"]; do not infer availability from a
cost before submitting.
- Select an exact model id and operation supported by that catalog.
- Announce the Atlas tool, provider, exact model, request count, and estimated
- Use local-path inputs when convenient. The tool uploads them through Atlas.
- Save outputs inside the active projects// tree and inspect them.
Video routes
Use canonical OpenMontage fields:
tool.execute({
"prompt": "...",
"model": "minimax/h3/reference-to-video",
"operation": "reference_to_video",
"duration": 10,
"resolution": "2K",
"reference_images": ["projects/demo/character.png"],
"reference_audios": ["projects/demo/performance.wav"],
"output_path": "projects/demo/h3.mp4",
})For Gemini developer reference video, pass videoclips objects with url, start, and ends. For H3, callers may pass normalized referenceimages, referencevideos, and referenceaudios; the tool converts them to refers.
Do not silently clamp duration, resolution, or ratio. Invalid values must fail before billing with the supported choices in the error.
Image routes
Set generationmode to generate, edit, or decompose. Source images can be supplied as imagepath, imagepaths, imageurl, or image_urls.
tool.execute({
"prompt": "Replace the packaging with matte cobalt glass; preserve the logo",
"model": "google/nano-banana-2/edit",
"generation_mode": "edit",
"image_paths": ["projects/campaign/source.png"],
"resolution": "2k",
"output_path": "projects/campaign/revised.png",
})Result and failure contract
Both tools submit to Atlas, poll the returned prediction id, download every output, and return ToolResult provenance containing the provider, exact model, prediction id, submitted parameters, source URL, artifact paths, and estimated cost. A missing key, unsupported route, invalid enum, missing media input, failed prediction, timeout, or download failure must return a failed result without switching providers.
Confirm current pricing and schemas from the machine-readable model page (Accept: text/markdown) immediately before quoting or spending on a batch.
