Generate vertical satisfying sugar-shell crack & pour shorts (WeryAI): text-to-video or dessert image to shell shatter and flowing center motion—first-three-second hook. Use when you need food ASMR cut, caramel crack dessert clips, or users ask for shell snap, lava pour, jelly wobble. SEO: sugar crack video; sugar crack video generation.

Sugar shell crack & pour video generation

Knife meets candied hawthorn shell—crack—shell splits, deep-red fruit pops—that frame loops forever. This skill targets those beats: shell break, lava pour, jelly wobble, sugar shards—crisp + flowing stacked for completion ceiling.

Text or one dessert image → 9:16 vertical.

Dependencies: WERYAI_API_KEY + Node.js 18+. When you run the CLI, scripts/video_gen.js must exist; WERYAI_VIDEO_API.md must exist under resources/ (supply both via publish or pre-use assembly). Full commands and JSON fields: see resources/WERYAI_VIDEO_API.md. No other Cursor skills. Default parameters and model tiers are in the tables below; live API limits follow weryai models. Before installing or running, review the bundled video_gen.js to confirm it meets your requirements. Pay particular attention to how it handles local files if you choose to allow their usage, ensuring this behavior aligns with the skill's intended workflow for image-to-video requests.

Prerequisites

• WERYAI_API_KEY must be set in the environment before running video_gen.js.
• Node.js 18+ is required. Prefer public https image URLs. If the assembled scripts/video_gen.js supports local file paths, review and verify the script first, then get explicit consent before it reads a local image and uploads it to WeryAI to obtain a public URL.
• Each successful wait run consumes WeryAI credits; re-running 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. Only WERYAI_API_KEY is read from the environment—do not rely on URL-related environment variables.
• Local image handling disclosure: Prefer public https image URLs. If the assembled scripts/video_gen.js supports local file paths, it may read a local image and upload it to WeryAI to obtain a public URL; require review / verification and explicit consent before using that path.
• 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. Verify whether the runtime can read local image files and upload them to WeryAI, and obtain explicit consent before using that path.

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.

When: The user gives only keywords, one line, or loose intent—or asks for richer video language. Exception: They paste a finished long prompt within the model's prompt_length_limit and ask you not to rewrite; still show the full text in the confirmation table.

Always add (video language): shot scale and angle; camera move or lock-off; light quality and motivation; subject action paced to duration; one clear payoff for this niche; state 9:16 vertical when this skill defaults to vertical.

Length: Obey prompt_length_limit for the chosen model_key when this doc lists it; trim filler adjectives before removing core action, lens, or light clauses.

Confirmation: The pre-submit table must include the full expanded prompt (never a one-line summary). Wait for confirm or edits.

Niche checklist

• Crack payoff: shell stress → snap, shards, powder dust; macro sugar texture; warm dessert light.
• Motion: slow break or single tap; interior reveal (mousse, fruit) if user asks.
• Audio: crisp crack if generate_audio true.

### Example prompts at the top of this file are short triggers only—always expand from the user's actual request.

Workflow

1. Confirm the user request matches this skill's scenario (text-to-video and/or image-to-video as documented).
2. Collect the user's brief, optional image URL(s), tier (best / good / fast) or an explicit model key.
3. Expand prompt (mandatory): Unless the user supplied a finished long prompt and explicitly asked not to rewrite it, expand the brief into a full English production prompt using ## Prompt expansion (mandatory) below. Do not call the API with only the user's minimal words.
4. Check the expanded prompt against the selected model's prompt_length_limit in the frozen tables in this document (when present); shorten if needed.
5. Verify duration, aspect_ratio, resolution, generate_audio, negative_prompt, and other fields against the frozen tables in this document and WERYAI_VIDEO_API.md.
6. Show the pre-submit parameter table including the full expanded prompt; wait for confirm or edits.
7. After confirmation, run node scripts/video_gen.js wait --json '...' with the expanded prompt.
8. Parse stdout JSON and return video URLs; on failure, surface errorCode / errorMessage and suggest parameter fixes.

CLI reference

sh

node scripts/video_gen.js wait --json '{"model":"…","prompt":"…","duration":5,"aspect_ratio":"9:16"}'

Definition of done

Done when the user receives at least one playable video URL from the API response, or a clear failure explanation with next steps. All parameters used must fall within the selected model's allowed sets in this document. The submitted prompt must be the expanded production prompt unless the user explicitly supplied a finished long prompt and asked not to rewrite it.

Boundaries (out of scope)

• We do not review platform compliance, copyright, or likeness; we do not warrant commercial usability of outputs.
• We do not provide offline rendering outside WeryAI, traditional NLE projects, or API field combinations not documented in this SKILL or WERYAI_VIDEO_API.md.
• Do not link to weryai-model-capabilities.md or shared ../references/ paths; use resources/WERYAI_VIDEO_API.md for CLI/API details.
• Do not hard-code absolute paths in this doc; run from the skill package root (next to SKILL.md) so scripts/ and resources/ paths resolve.

Example prompts

• Crème brûlée: knife taps shell, crack then lava pours, vertical food satisfying
• From this layer cake: slice motion, cream pull
• Food short: shell *snap* + jam burst, warm appetite light
• Satisfying dessert crack 9:16, shell shatter then gooey center pour

Text → sugar crack & pour

Describe dessert type and how it’s opened—no assets required. Good for batching different foods or testing shell vs. lava vs. jelly.

Say what it is (candied hawthorn shell / lava cake / flowing pudding / crystal jelly / filled dessert) and how it breaks (single slice / spoon press / toothpick poke / squeeze burst). Build prompt from shell thickness, viscosity, color contrast, plus crack sound, pour beat, and light.

Flow:

1. Collect food + cut style; extract shell feel, pour color, peak beat; build prompt
2. Show this run’s parameters; wait for confirmation:

   About to generate—confirm to start (reply "confirm" or list changes):

   • model: KLING_V3_0_PRO
   • aspect_ratio: 9:16
   • duration: 5
   • generate_audio: true
   • seamless loop: off (reply "loop" to append seamless loop, perfectly looping video, first and last frame identical)

3. After confirmation run node scripts/video_gen.js wait --json '…' with model, prompt, aspect_ratio, duration, generate_audio matching the table; parse stdout for URLs

Parameters:

Field	Value
model	KLING_V3_0_PRO
aspect_ratio	9:16
duration	5
generate_audio	true

Expanded prompt: Compose at generation time per ## Prompt expansion (mandatory) from the user's actual brief—do not reuse fixed sample paragraphs.

Expected outcome: Shell break + pour land in the first ~3 s; slow-mo is screenshot-friendly; ASMR synced to visuals; vertical ready to post.

Note: For lava shots, name the pour color in prompt (e.g. vivid matcha green lava, molten dark chocolate)—higher saturation and contrast vs. shell strengthens the hook.

Dessert image → crack / pour motion

Provide a dessert image URL; generate cut / pour motion anchored on that subject. Good for turning plating or product stills into video.

Prefer a publicly reachable https URL for the reference. Optional: motion direction (slice pour / shell shatter / jelly wobble / spoon crush). Infer shell, filling color, and shape from the image; keep look consistent with the reference.

Flow:

1. Collect URL + motion direction; infer food traits; build motion prompt
2. Show parameters; wait for confirmation:

   About to generate—confirm to start (reply "confirm" or list changes):

   • model: KLING_V3_0_PRO
   • aspect_ratio: 9:16
   • duration: 5
   • generate_audio: true
   • image: (your URL)
   • seamless loop: off (reply "loop" to enable)

3. After confirmation run node scripts/video_gen.js wait --json '…' including image plus same fields as text path; parse stdout

Parameters:

Field	Value
model	KLING_V3_0_PRO
aspect_ratio	9:16
duration	5
generate_audio	true
image	User image URL

Sample prompt:

Based on the provided image, animate this dessert being cut open: a sharp knife blade enters from the top in extreme close-up macro slow motion at 120fps, the outer shell or crust fractures cleanly along the cut line matching the color and texture of the original food in the image, the interior filling or lava erupts and flows outward maintaining the color palette visible in the image, warm side lighting enhances the viscosity of the flowing interior, ASMR crack and pour sound, the overall color tone and plating style matches the reference image, dark slate background

Expected outcome: Motion matches the dish; shell break and pour feel natural; strong before/after vs. still.

Note: Prefer public https URLs; login-gated links may fail the API. If the assembled scripts/video_gen.js supports local file paths, review/verify the script and explicitly consent before local read-and-upload to WeryAI. Clearer food and cleaner backgrounds improve accuracy.

Prompt boosters

Drop-in phrases by food type:

Shell shatter: crystalline sugar shell shatters, amber caramel crust fractures radially, tempered sugar explodes into prismatic shards, sugar crust collapses inward

Lava pour: molten lava erupts in viscous surge, liquid chocolate center oozes out slowly, thick custard floods the plate, lava flow catches backlight glowing translucent

Jelly wobble: jelly wobbles in satisfying slow motion, translucent cube trembles after cut, cross-section glistens catching blue backlight, jelly oscillation dampens slowly

Light: caustic light refraction through sugar crystal, backlit lava glowing at translucent edges, cold rim lighting on cut surface, warm amber bokeh in background
