## What it does

This skill adds new visual layouts to the local handraw-style catalog. It assigns IDs based on type: SC for social cards, IG for infographics, SB for storyboards, and IP for characters. The workflow operates only inside the local repository. It edits `references/layouts.json` directly and never pushes commits automatically.

Images must convert to WebP losslessly. The skill uses Python and Pillow to handle this step. If Pillow is missing, asset processing stops immediately. The skill never crops or recolors supplied assets. It then creates a Markdown prompt file containing parallel layout descriptions in English and Chinese.

Batch mode keeps consecutive imports fast. The tool skips gallery rebuilds until you request a full sync. Once triggered, `build_layout_gallery.py` refreshes `layouts.html` and runs `validate_library.py` to catch broken entries.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add yang0/handraw-style --skill layout-library-importer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/layout-library-importer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/layout-library-importer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add yang0/handraw-style --skill layout-library-importer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/layout-library-importer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add yang0/handraw-style --skill layout-library-importer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/layout-library-importer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install yang0/handraw-style layout-library-importer
```

2. **Manually: put the files in place**
- File: `.github/skills/layout-library-importer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add yang0/handraw-style --skill layout-library-importer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/yang0/handraw-style --path skills/layout-library-importer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/layout-library-importer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yang0/handraw-style --skill layout-library-importer -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- convert layout images to lossless WebP format using Pillow
- register new layout entries in references/layouts.json with sequential IDs
- generate bilingual Markdown prompts documenting composition and whitespace
- rebuild the derived HTML gallery and validate library entries

## Example prompts
- Import this attached image as a new social-card layout
- Add this infographic layout to the library with composition constraints
- Rebuild the layout gallery and run the full validation check

# Layout Library Importer

Use this Skill when the user wants to add a new visual layout/type to the local hand-drawn layout gallery. This is a repository-local workflow: do not commit, push, publish, or install anything externally unless the user separately asks.

## Source of truth

Work from the repository root and read the live implementation before editing:

- `skills/handdraw-style-prompter/references/layouts.json` is the layout index.
- `skills/handdraw-style-prompter/references/layouts/*.md` is the authoritative bilingual prompt content.
- `images/layouts/social-cards/`, `images/layouts/infographics/`, `images/layouts/comic-storyboards/`, and `images/layouts/ip-characters/` hold the layout images; canonical assets use WebP.
- `skills/handdraw-style-prompter/scripts/build_layout_gallery.py` rebuilds the derived gallery.
- `skills/handdraw-style-prompter/scripts/validate_library.py` is the full validation command.

Preserve unrelated dirty work. Inspect `git status --short` before editing and do not reset, clean, or overwrite files outside the requested layout import.

## Import workflow

### Batch input mode

Unless the user explicitly asks to rebuild, treat consecutive layout imports as batch input. For each supplied image, convert it to WebP when needed, add its index entry, and create its bilingual prompt file, but do not rebuild `gallery/layouts.html` or run the full validator after each item.

When the user says `重建索引`, rebuild the layout gallery once from the accumulated canonical index and run the full validation and whitespace check. The canonical index is `references/layouts.json`; this request means regenerate and validate its derived gallery, not recreate the index entries already recorded.

1. Determine the next ID from the live index. Use the next number within the requested category: `SC-###` for `social-card`, `IG-###` for `infographic`, `SB-###` for `comic-storyboard`, `IP-###` for `ip-character`. Never reuse an existing ID or infer a number from a filename alone.
2. Treat the user-supplied image as the canonical visual source. The repository asset must always use the `.webp` extension. If the supplied image is already WebP, copy it to the category directory with the new ID. If it is another format, convert it to WebP losslessly using Python:

   ```powershell
   python -c "from PIL import Image; img = Image.open(r'<input>'); img.save(r'<target>.webp', format='WEBP', lossless=True)"
   ```
