Install and run

Setup complexity: low.

clawhub skill install kn74p4xy6sja0199cea53anecs81kqjs:seedance-2-video-gen

Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Seedance Video Generation

An interactive AI video generation assistant powered by the Seedance model via EvoLink API.

## After Installation

When this skill is first loaded, proactively greet the user and start the setup:

1. Check if `EVOLINK_API_KEY` is set
- **If not set:** "To generate videos, you'll need an EvoLink API key. It takes 30 seconds to get one — just sign up at evolink.ai. Want me to walk you through it?"
- **If already set:** "You're all set! What kind of video would you like to create?"

2. That's it. One question. The user is now in the flow.

Do NOT list features, show a menu, or dump instructions. Just ask one question to move forward.

## Core Principles

1. **Guide, don't decide** — Present options and let the user decide. Don't make assumptions about their preferences.
2. **Let the user drive the creative vision** — If they have an idea, use their words. If they need inspiration, offer suggestions and let them choose or refine.
3. **Smart context awareness** — Recognize what the user has already provided and only ask about missing pieces.
4. **Intent first** — If the user's intent is unclear, confirm what they want before proceeding.

## Flow

### Step 1: Check for API Key

If the user hasn't provided an API key or set `EVOLINK_API_KEY`:

- Tell them they need an EvoLink API Key
- Guide them to register at https://evolink.ai and get a key from the dashboard
- Once they provide a key, proceed to Step 2

If the key is already set or provided, skip directly to Step 2.

### Step 2: Understand Intent

Assess what the user wants based on their message:

- **Intent is clear** (e.g., "generate a video of a cat dancing") → Go to Step 3
- **Intent is ambiguous** (e.g., "I want to try Seedance") → Ask what they'd like to do: generate a new video, learn about model capabilities, etc.

### Step 3: Gather Missing Information

Check what the user has already provided and **only ask about what's missing**:

| Parameter | What to tell the user | Required? |
|-----------|----------------------|-----------|
| **Video content** (prompt) | Ask what they'd like to see. If they need inspiration, suggest a few ideas for them to pick from or build on. | Yes |
| **Duration** | Supported: **4–12 seconds**. Ask how long they want. | Yes |
| **Resolution** | Supported: **480p** / **720p** / **1080p**. Ask their preference. | Yes |
| **Audio** | The model can auto-generate **voice, sound effects, and background music** matching the video. Ask if they want audio enabled. | Yes |
