# Art Skill

Complete visual content system for creating illustrations, diagrams, and visual content.

## Customization

**Before executing, check for user customizations at:**
`~/.Codex/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/`

If this directory exists, load and apply:
- `PREFERENCES.md` - Aesthetic preferences, default model, output location
- `CharacterSpecs.md` - Character design specifications
- `SceneConstruction.md` - Scene composition guidelines

These override default behavior. If the directory does not exist, proceed with skill defaults.

## MANDATORY: Output to Downloads First

```
ALL GENERATED IMAGES GO TO ~/Downloads/ FIRST
NEVER output directly to project directories
User MUST preview in Finder/Preview before use
```

**This applies to ALL workflows in this skill.**

## Voice Notification

**When executing a workflow, do BOTH:**

1. **Send voice notification**:
   ```bash
   curl -s -X POST http://localhost:8888/notify \
     -H "Content-Type: application/json" \
     -d '{"message": "Running the WORKFLOWNAME workflow from the Art skill"}' \
     > /dev/null 2>&1 &
   ```

2. **Output text notification**:
   ```
   Running the **WorkflowName** workflow from the **Art** skill...
   ```

---

## Workflow Routing

Route to the appropriate workflow based on the request.

  - Blog header or editorial illustration -> `Workflows/Essay.md`
  - Visualization or chart -> `Workflows/Visualize.md`
  - Mermaid flowchart or sequence diagram -> `Workflows/Mermaid.md`
  - Technical or architecture diagram -> `Workflows/TechnicalDiagrams.md`
  - Framework or 2x2 matrix -> `Workflows/Frameworks.md`
  - Stat card or big number visual -> `Workflows/Stats.md`
  - PAI pack icon -> `Workflows/CreatePAIPackIcon.md`

---

## Core Aesthetic

**Default:** Production-quality concept art style appropriate for editorial and technical content.

**UL Editorial Color Palette:**
```
Background: Light Cream #F5E6D3 or White #FFFFFF
Primary Accent: Deep Purple #4A148C (strategic, 10-20%)
Secondary Accent: Deep Teal #00796B (5-10%)
Structure: Black #000000
Text: Charcoal #2D2D2D
```

**Typography System (3-Tier):**
- Tier 1 (Headers): Valkyrie-style elegant wedge-serif italic
- Tier 2 (Labels): Concourse-style geometric sans-serif
- Tier 3 (Insights): Advocate-style condensed italic for callouts

**Load customizations from:** `~/.Codex/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/PREFERENCES.md`

---

## Image Generation

**Default model:** Check user customization at `SKILLCUSTOMIZATIONS/Art/PREFERENCES.md`
**Fallback:** nano-banana-pro (best text rendering)

### CRITICAL: Always Output to Downloads First

**ALL generated images MUST go to `~/Downloads/` first for preview and selection.**

Never output directly to a project's `public/images/` directory. User needs to review images in Preview before they're used.

**Workflow:**
1. Generate to `~/Downloads/[descriptive-name].png`
2. User reviews in Preview
3. If approved, THEN copy to final destination
4. Create WebP and thumbnail versions at final destination

```bash
# CORRECT - Output to Downloads for preview
bun run ~/.Codex/skills/Art/Tools/Generate.ts \
  --model nano-banana-pro \
  --prompt "[PROMPT]" \
  --size 2K \
  --aspect-ratio 1:1 \
  --thumbnail \
  --output ~/Downloads/blog-header-concept.png

# After approval, copy to final location
cp ~/Downloads/blog-header-concept.png ~/Projects/Website/cms/public/images/
```

### Multiple Reference Images (Character/Style Consistency)

For improved character or style consistency, use multiple `--reference-image` flags:

```bash
# Multiple reference images for better likeness
bun run ~/.Codex/skills/Art/Tools/Generate.ts \
  --model nano-banana-pro \
  --prompt "Person from references at a party..." \
  --reference-image face1.jpg \
  --reference-image face2.jpg \
  --reference-image face3.jpg \
  --size 2K \
  --aspect-ratio 16:9 \
  --output ~/Downloads/character-scene.png
```

**API keys in:** your agent config `.env` (e.g. `~/.agents/.env`)

## Examples

**Example 1: Blog header image**
```
User: "create a header for my AI agents post"
-> Invokes ESSAY workflow
-> Generates editorial illustration prompt
-> Creates image with consistent aesthetic
-> Saves to ~/Downloads/ for preview
-> After approval, copies to public/images/
```

**Example 2: Technical architecture diagram**
```
User: "make a diagram showing the SPQA pattern"
-> Invokes TECHNICALDIAGRAMS workflow
-> Creates structured architecture visual
-> Outputs PNG with consistent styling
```

**Example 3: Framework visualization**
```
User: "create a 2x2 matrix for security vs convenience"
-> Invokes FRAMEWORKS workflow
-> Creates hand-drawn framework visual
-> Purple highlights optimal quadrant
```

**Example 4: PAI pack icon**
```
User: "create icon for the skill system pack"
-> Invokes CREATEPAIPACKICON workflow
-> Generates 1K image with --remove-bg for transparency
-> Resizes to 256x256 RGBA PNG
-> Outputs to ~/Downloads/ for preview
```
