# Model Studio Digital Human

## Validation

```bash
mkdir -p output/aliyun-wan-digital-human
python -m py_compile skills/ai/video/aliyun-wan-digital-human/scripts/prepare_digital_human_request.py && echo "py_compile_ok" > output/aliyun-wan-digital-human/validate.txt
```

Pass criteria: command exits 0 and `output/aliyun-wan-digital-human/validate.txt` is generated.

## Output And Evidence

- Save normalized request payloads, chosen resolution, and task polling snapshots under `output/aliyun-wan-digital-human/`.
- Record image/audio URLs and whether the input image passed detection.

Use this skill for image + audio driven speaking, singing, or presenting characters.

## Critical model names

Use these exact model strings:
- `wan2.2-s2v-detect`
- `wan2.2-s2v`

Selection guidance:
- Run `wan2.2-s2v-detect` first to validate the image.
- Use `wan2.2-s2v` for the actual video generation job.

## Prerequisites

- China mainland (Beijing) only.
- Set `DASHSCOPE_API_KEY` in your environment, or add `dashscope_api_key` to `~/.alibabacloud/credentials`.
- Input audio should contain clear speech or singing, and input image should depict a clear subject.

## Normalized interface (video.digital_human)

### Detect Request
- `model` (string, optional): default `wan2.2-s2v-detect`
- `image_url` (string, required)

### Generate Request
- `model` (string, optional): default `wan2.2-s2v`
- `image_url` (string, required)
- `audio_url` (string, required)
- `resolution` (string, optional): `480P` or `720P`
- `scenario` (string, optional): `talk`, `sing`, or `perform`

### Response
- `task_id` (string)
- `task_status` (string)
- `video_url` (string, when finished)

## Quick start

```bash
python skills/ai/video/aliyun-wan-digital-human/scripts/prepare_digital_human_request.py \
  --image-url "https://example.com/anchor.png" \
  --audio-url "https://example.com/voice.mp3" \
  --resolution 720P \
  --scenario talk
```

## Operational guidance

- Use a portrait, half-body, or full-body image with a clear face and stable framing.
- Match audio length to the desired output duration; the output follows the audio length up to the model limit.
- Keep image and audio as public HTTP/HTTPS URLs.
- If the image fails detection, do not proceed directly to video generation.

## Output location

- Default output: `output/aliyun-wan-digital-human/request.json`
- Override base dir with `OUTPUT_DIR`.

accelint-react-best-practices

Included

React performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.

humanizer

Included

Humanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.
