# Kling 3.0 Omni Video Generator

This skill enables the generation and manipulation of videos using the Kling 3.0 Omni model. It provides a structured workflow for constructing API requests based on user intent, ensuring compliance with the model's complex parameter constraints.

## Reference Files

This skill includes the following reference files:

- `references/api_reference.md` — **Complete official API parameter reference**, including all fields, types, constraints, mutual exclusion rules (R1–R10), capability matrix, and invocation examples. **Read this file before constructing any API call.**
- `references/prompt_guide.md` — Kling 3.0 Omni prompt writing principles, official formula, template syntax, and few-shot examples for all major scenarios.
- `scripts/kling_api.py` — Python utility class for JWT authentication, task creation, and polling.

## Core Capabilities

- **Text-to-Video**: Generate a video from a textual description.
- **Image-to-Video**: Animate a static image with a descriptive prompt.
- **Video-to-Video (Editing)**: Modify an existing video based on a prompt (e.g., change subject, style).
- **Video-to-Video (Reference)**: Use an existing video as a reference for camera movement and style.
- **Multi-shot Generation**: Create a video with multiple distinct scenes or shots.
- **Audio Generation**: Generate video with synchronized audio, including speech and sound effects.

## Workflow: From User Intent to API Call

To correctly use the Kling API, you MUST follow this decision-making workflow to construct the API payload. The process is divided into two main stages: **Prompt Design** and **Parameter Construction**.

### Stage 1: Prompt Design

Before constructing the API call, you must first design the prompt(s) based on the user's request. The quality of the prompt is the single most important factor for a good result.

1.  **Consult the Prompting Guide**: Read `/home/ubuntu/skills/kling-video-generator/references/prompt_guide.md` to understand the core principles, official formula, and few-shot examples for writing effective prompts.

2.  **Identify the Scenario**: Determine which of the following scenarios the user is requesting:
    -   Single-shot video (from text, image, or video)
    -   Multi-shot video (storyboard with multiple scenes)

3.  **Write the Prompt(s)**:
    -   For **single-shot**, write a single, detailed prompt following the guide's formula.
    -   For **multi-shot**, write a separate prompt for each shot/scene.
    -   **Use Template Syntax**: If the user provides reference images, elements, or videos, you MUST use the `<<<image_1>>>`, `<<<element_1>>>`, `<<<video_1>>>` template syntax in the prompt to explicitly reference them. This is a core feature of the Omni model.

### Stage 2: Parameter Construction

Once the prompt(s) are ready, construct the final API request payload by following this decision tree. This ensures all parameter constraints and interdependencies, discovered through extensive testing, are respected.
