Gardening & plant growth video generation

A seed in soil, roots reaching down, cotyledons breaking the surface, stems stretching day by day, buds swelling, a flower opening in sun—ten seconds can hold a whole life cycle; that’s the magic of timelapse. Bunny with strawberries, bear with succulents, cat with balcony tomatoes: growth is the plot.

Dependencies: scripts/video_gen.js in this directory + WERYAI_API_KEY + Node.js 18+. No dependency on other Cursor skills.

Prerequisites

• WERYAI_API_KEY must be set in the environment before running video_gen.js.
• Node.js 18+ is required. Image inputs must be public https URLs (no local file paths).
• 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).
• Optional URL overrides (WERYAI_BASE_URL, WERYAI_MODELS_BASE_URL): video_gen.js defaults to https://api.weryai.com and https://api-growth-agent.weryai.com. Overrides are intended for testing or approved alternate endpoints. If these variables are set in your environment, confirm they point to hosts you trust—otherwise prompts, images, and your bearer token could be sent elsewhere.
• 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.

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

• Time language: time-lapse, visible days/weeks compression, light angle or shadow drift for elapsed time.
• Beats: seed/sprout/leaf/flower/fruit as applicable; hands or paws optional; terracotta, soil, glass root views.
• Payoff: harvest, full bloom, or filled planter clearer than start.

### 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 and API notes in this SKILL.md.
6. Show the pre-submit parameter table including the full expanded prompt; wait for confirm or edits.
7. After confirmation, run node {baseDir}/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

node {baseDir}/scripts/video_gen.js wait --json '{"model":"…","prompt":"…","duration":5,"aspect_ratio":"9:16"}'
node {baseDir}/scripts/video_gen.js wait --json '…' --dry-run
node {baseDir}/scripts/video_gen.js status --task-id <id>

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)

• Does not review platform compliance, copyright, or portrait rights; does not guarantee commercial usability of outputs.
• Does not provide non-WeryAI offline rendering, traditional edit timelines, or API field combinations not documented here.
• Does not hard-code absolute paths in the skill doc; {baseDir} means the skill package root (same level as SKILL.md).

Example prompts

• Bunny grows tomatoes on a balcony: seed to red fruit on the vine, vertical timelapse growth
• Use this succulent pot image: leaves plump and colors intensify over days
• Mushrooms from bag to harvest, healing natural light
• Cozy plant growth timelapse 9:16, window sunlight, cute animal gardener

Default parameters

API validity (default KLING_V3_0_PRO): Text-to-video duration only 5 / 10 / 15; aspect_ratio only 9:16, 1:1, 16:9. Image-to-video aspect_ratio only 9:16, 16:9, 1:1. No resolution field—do not send it. For fast tier with VEO: text-to-video VEO_3_1_FAST, image-to-video CHATBOT_VEO_3_1_FAST, with duration fixed at 8, aspect_ratio only 9:16 or 16:9. When switching model_key, follow the allowed sets in this section’s model/API constraints and the API validity note above; do not send resolution to models that do not support it.

Seed to sprout to flower and fruit

Purpose: Time-compressed growth from planting through a satisfying harvest or bloom. Hero beats: breaking soil and the final flower or fruit moment.

Describe the character and plant—no extra form:

e.g. “bunny grows strawberries” or “cat grows balcony tomatoes”—the skill fills in the full growth arc and visual detail.

Show parameters before generate:

Generating with the parameters below—reply confirm or say what to change:

• model: KLING_V3_0_PRO
• aspect_ratio: 9:16
• duration: 10
• generate_audio: false
• Loop seam: No (reply loop to enable; appends seamless loop to the prompt)

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

Parameter configuration:

Expected outcome: Clear time advance; sprouting and bloom/fruit as peaks; light cycles or angle shifts sell the passage of time; ending feels like a payoff.

Microscopic growth close-ups

Single-plant life at extreme detail: roots in a clear vessel, bud-to-full-bloom timelapse, mushroom from spore stage to pickable—no long story, one magnified process.

Name the plant and stage; then generate:

You must show all parameters in a table and wait for explicit user confirmation before submitting:

📋 Ready to generate—please confirm:

Parameter	This run	Notes
model	KLING_V3_0_PRO	Best default; say “cheap / draft / fast” → KLING_V3_0_STA; say “balanced” → WAN_2_6; or name a model

generate_audio	false	Whether to auto-generate audio
prompt	Full expanded English prompt (entire text for this run)	Revise before confirm

Reply “confirm” to start, or list what to change.

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

Prompt tips

Timelapse feel: time-lapse compression, days visible in seconds, light cycles through the sequence, daily shadows rotate revealing passage of time

Life beats: seedling breaks through soil surface, root tip emerges driven by gravity, flower petals open in slow motion, fruit swells and deepens in color

Texture: terracotta pot texture, soil granularity visible, glass-sided container reveals root system, morning window light on dew-covered leaves

Note: Say time-lapse explicitly or the model may output a static plant instead of growth. Adding light cycling or shadow angle changing strengthens the sense of elapsed time.
