Holy ceremony & celebration style transform (Seedance 2.0)

Blessed spectacle: volumetric holy shafts, gold dust, white rose petals, dignified poses, choir-wide audio hints when enabled.

Dependencies: WERYAI_API_KEY + Node.js 18+. This skill uses only SEEDANCE_2_0. When you run the CLI, {baseDir}/scripts/video_gen.js must exist; WERYAI_VIDEO_API.md must exist under {baseDir}/resources/ (supply both via publish or pre-use assembly). Full commands and JSON fields: see resources/WERYAI_VIDEO_API.md. No other Cursor skills required.

Prerequisites

• WERYAI_API_KEY must be set before running video_gen.js.
• Node.js 18+; image inputs must be public https URLs (no local paths).
• Model (caller / agent): The bundled video_gen.js requires a non-empty model in JSON—if model is missing or blank, the CLI exits with MISSING_PARAM (no default model). The script does not enforce this skill's allowed model in code: you must set "model":"SEEDANCE_2_0" for this package and show it in the confirmation table before submit—see WERYAI_VIDEO_API.md (model row).
• Each wait run may consume credits; re-run creates new paid tasks.

Security, secrets, and API hosts

• WERYAI_API_KEY: Treat as a secret. Only configure it if you trust this skill's source; it is listed in OpenClaw metadata as requires.env / primaryEnv so installers know it is mandatory at runtime (never commit it inside the skill package).
• API hosts (fixed in video_gen.js): Video tasks use https://api.weryai.com; the models list uses https://api-growth-agent.weryai.com. Child skills must not document or rely on URL environment-variable overrides—only WERYAI_API_KEY is read from the environment.
• Higher assurance: Run generation in a short-lived or isolated environment (separate account or container), and review scripts/video_gen.js (HTTPS submit + poll loop) before production use.

Prompt expansion (mandatory)

video_gen.js does not expand prompts. Before every wait --json, turn the user's short or vague brief into a full English production prompt that re-styles the described event into this skill's look.

When: User input is short, vague, or missing cinematic detail. Exception: They supply a finished long prompt within 2000 characters and ask you not to rewrite—still show the full text in the confirmation table.

Always add: shot size and angle; camera move; lighting and color grade aligned to this skill; subject action paced to duration; one clear payoff; platform framing (9:16 unless user chose another allowed ratio); if generate_audio is true, describe ambience / SFX in generic words (no copyrighted music references).

Length: Stay within prompt_length_limit 2000 for SEEDANCE_2_0; trim adjectives before losing the core transformation beat.

Confirmation: The pre-submit table must include the full expanded prompt.

Style transformation checklist

• Light: soft gold rim + cool fill for cleanliness; lens bloom controlled.
• Color: white, gold, soft champagne—avoid muddy shadows.
• Space: cathedral scale or grand hall pillars—even if implied with light shafts.
• Motion: slow raise of hands, crown moment, gentle spin—proud not chaotic.
• Particles: confetti as blessing, soft sparkles, not clutter.
• Sound (if on): organ pad, distant choir, bell swell—generic descriptors.

Fits: Weddings, graduations, product launches, year-end gratitude, faith-positive mood.

### Example prompts below are richness targets only—always derive from the user's actual brief.

Workflow

1. Confirm the request matches this skill (text-to-video and/or single image-to-video).
2. Collect the user's brief, optional image URL, and tier (best / good / fast)—all map to SEEDANCE_2_0 with different duration defaults (see Recommended models).
3. Expand prompt (mandatory): Unless the user opted out with a finished long prompt, expand using ## Prompt expansion (mandatory). Do not submit only the user's minimal words.
4. Validate model is SEEDANCE_2_0 only; validate duration, aspect_ratio, resolution, generate_audio against the frozen tables.
5. Show the confirmation table with the full expanded prompt; wait for confirm or edits.
6. Run node {baseDir}/scripts/video_gen.js wait --json '...'.
7. Parse stdout JSON; return videos URLs or explain errors.
8. When presenting playable URLs to the user, use Markdown inline links only (e.g. [Video](https://...)). Do not wrap user-facing links in code fences.

CLI reference

node {baseDir}/scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"…","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}'

Full reference: WERYAI_VIDEO_API.md.

Definition of done

Done when the user gets at least one playable Video-style link, or a clear failure with next steps. Submitted prompt must be the expanded prompt unless the user explicitly opted out. Never use another model_key in this skill.

Boundaries (out of scope)

• Do not use any model other than SEEDANCE_2_0 for this package.
• Do not link to weryai-model-capabilities.md or shared ../references/ paths; use resources/WERYAI_VIDEO_API.md for CLI/API details.
• Do not use local file paths for image; never embed the secret value of WERYAI_API_KEY in files.
• Do not invent API fields; do not send negative_prompt (not supported for this model).
• Do not wrap user-facing playable URLs in Markdown code fences.

Example prompts

• Team high-five → golden light burst, slow motion, confetti rain, vertical
• Opening gift box → rays from inside, white petals drift, gentle awe
• HTTPS family photo → soft halation, ceremonial frame, warm dignity

Model and API constraints (frozen for this skill)

Derived from node {baseDir}/scripts/video_gen.js models alignment at authoring time; re-run models after platform upgrades. This skill is locked to SEEDANCE_2_0 only.

Text-to-video

Image-to-video (single image)

Recommended models

Tier only changes duration / resolution / audio defaults—never the model.

Default parameters

Scenario: Text-to-video style transform

Flow

1. Capture the user's mundane event in one or two sentences.
2. Expand into English with the Style transformation checklist; keep identity generic unless user names a character.
3. Confirmation table → user confirm.
4. Execute:

node {baseDir}/scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"\x3Cexpanded>","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}'

5. Return [Video](url) links.

Scenario: Image-to-video style transform

Before use: image must be https:// and reachable.

1. Plan how the still re-styles in motion (props, light, environment) without breaking likeness if the user requests preservation.
2. Expand prompt; add image to the confirmation table.
3. After confirm:

node {baseDir}/scripts/video_gen.js wait --json '{"model":"SEEDANCE_2_0","prompt":"\x3Cexpanded>","image":"https://…","duration":10,"aspect_ratio":"9:16","resolution":"720p","generate_audio":true}'

4. Return [Video](url) links.

Loop seam (optional)

If the user asks for a seamless loop, append a short English trio at the end of the expanded prompt: seamless loop, perfect loop, ends where it begins—no separate API flag.
