output/alicloud-ai-video-wan-r2v/validate.txt Pass criteria: command exits 0 and output/alicloud-ai-video-wan-r2v/validate.txt is generated. Output And Evidence Save reference input metadata, request payloads, and task outputs in output/alicloud-ai-video-wan-r2v/ . Keep at least one polling result snapshot. Use Wan R2V for reference-to-video generation. This is different from i2v (single image to video). Critical model names Use one of these exact model strings: wan2.6-r2v-flash wan2.6-r2v Prerequisites Install SDK in a virtual environment: python3 -m venv .venv . .venv/bin/activate python -m pip install dashscope Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials . Normalized interface (video.generate_reference) Request prompt (string, required) reference_video (string | bytes, required) reference_image (string | bytes, optional) duration (number, optional) fps (number, optional) size (string, optional) seed (int, optional) Response video_url (string) task_id (string, when async) request_id (string) Async handling Prefer async submission for production traffic. Poll task result with 15-20s intervals. Stop polling when SUCCEEDED or terminal failure status is returned. Local helper script Prepare a normalized request JSON and validate response schema: .venv/bin/python skills/ai/video/alicloud-ai-video-wan-r2v/scripts/prepare_r2v_request.py \ --prompt "Generate a short montage with consistent character style" \ --reference-video "https://example.com/reference.mp4" Output location Default output: output/alicloud-ai-video-wan-r2v/videos/ Override base dir with OUTPUT_DIR . Workflow Confirm user intent, region, identifiers, and whether the operation is read-only or mutating. Run one minimal read-only query first to verify connectivity and permissions. Execute the target operation with explicit parameters and bounded scope. Verify results and save output/evidence files. References references/sources.md
