Seedance2.5

Plan and prompt video production from material the user can verify. This skill produces an editable production plan and prompt pack; the active Seedance interface determines the generation controls and renders the final media.

Capabilities

Read references/video-routes.md for the chosen route. Read references/route-templates.md to produce a route-specific brief and prompt preamble. Read references/production-contract.md before any multi-clip production task. Read references/prompt-patterns.md while writing or repairing prompts.

Honest boundary

• Preserve supplied facts, dialogue, people, products, and reference assets. Ask rather than fill gaps with plausible fiction.
• Build prompts, plans, and QA; do not claim to render the final video, clone a person, create a voice, or use a platform feature unless the active interface supports it.
• Require authorization for reference images, videos, voices, performers, and brands. Do not imitate protected characters or living performers without permission.
• Treat the active Seedance UI/API as authoritative for duration, aspect ratio, audio, editing, and reference-asset controls.

Workflow

1. Lock the production brief

Record only what changes the output: target audience and platform, source material, approved facts/assets, delivery format, sound policy, and whether the work is draft or locked.

For marketing work, use only claims supported by the user’s brief. For talking-head work, keep the supplied language intact and plan supporting visuals rather than rewriting the speaker’s voice.

2. Select the smallest route

Do not force every request through a screenplay workflow. A 15-second product demo needs proof beats; a talking-head edit needs B-roll timing; a short drama needs a scene ledger. Use the relevant route template and omit unrelated deliverables.

3. Plan before prompting

Make the visible story clear before adding style words. Each clip needs a purpose, an opening state, one playable change, and an ending state. Carry confirmed state forward; do not reset people, props, location, lighting, or product details between clips.

4. Write prompts in production order

Use the structure in references/prompt-patterns.md: references, start state, camera/action, dialogue/sound, end state, and only necessary constraints. Prefer observable direction over vague labels such as “premium” or “cinematic.”

5. QA the pack

Validate the route brief first:

python3 scripts/validate_video_plan.py --route short-video path/to/plan.md

For a multi-clip pack, run:

python3 scripts/validate_prompt_pack.py path/to/prompt-pack.md

Replace short-video with marketing, talking-head, product-demo, or narrative as appropriate. Resolve errors. Treat warnings as a prompt to manually check whether the next clip has enough inherited state.

Delivery

Return only the route-relevant artifacts: brief, fact/asset list, beat or clip plan, prompt pack, and unresolved assumptions. For multi-clip work, include the validator result.
