SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? It prevents unwanted prompt rewriting and model switching when generating videos, ensuring the Seedance 2.5 model receives the user's exact original prompt with validated duration and aspect ratio parameters. ## Core Features & Use Cases - Verbatim Prompt Passthrough: Forbids any rewriting, polishing, translation, or expansion of the user's video prompt before sending it to the generation tool. - Fixed Model Enforcement: Locks model_version to seedance_2.5 and refuses to downgrade or substitute other models. - Parameter Validation & Confirmation: Auto-suggests duration (5-30 seconds) and aspect ratio (16:9, 4:3, 1:1, 3:4, 9:16, 21:9) based on content type, then requires explicit user confirmation before generation. - Use Case: A marketer provides a finished prompt for a 15-second vertical product ad; the Skill confirms the exact prompt, 9:16 ratio, and duration, then generates the video without altering a single character. ## Quick Start Use the seedance-25 skill to generate a video with Seedance 2.5 using my exact prompt without any modifications.

FAQPage Schema
How do I generate a video with Seedance 2.5 without prompt rewriting?

Provide your final prompt and state it must be passed verbatim. The Skill locks model_version to seedance_2.5, displays your exact prompt in a confirmation block, and only calls the video tool after your explicit approval.

What aspect ratios does Seedance 2.5 video generation support?

Seedance 2.5 supports exactly six aspect ratios: 16:9, 4:3, 1:1, 3:4, 9:16, and 21:9. If you request an unsupported ratio, generation stops and you must choose from the supported list.

What video duration limits apply to Seedance 2.5?

Seedance 2.5 accepts integer durations from 5 to 30 seconds. Requests outside this range are rejected with a prompt to pick a valid duration rather than switching to another model.

Can the skill modify or improve my video prompt automatically?

No. The Skill treats your prompt as an immutable string and forbids expansion, polishing, translation, or adding style keywords. Any changes require you to supply a new final version, which is then passed verbatim.

What happens if the video tool does not support seedance_2.5?

Generation stops and the Skill explicitly informs you that the model is unavailable. It never downgrades or substitutes a different model version on its own.

When does the skill search the web before video generation?

Retrieval triggers when prompts mention Doubao character imagery or contain time-sensitive words like latest, recent, or today involving brands, people, or events. Retrieved facts are listed separately in the confirmation and never merged into your prompt.
