# Art Skill

Visual content generation system using **Excalidraw hand-drawn** aesthetic with dark-mode, tech-forward color palette.

## Output Location

```
ALL GENERATED IMAGES GO TO ~/Downloads/ FIRST
Preview in Finder/Preview before final placement
Only copy to project directories after review
```

## Workflow Routing

Route to the appropriate workflow based on the request:

  - Technical or architecture diagram -> `Workflows/TechnicalDiagrams.md`
  - Blog header or editorial illustration -> `Workflows/Essay.md`
  - Comic or sequential panels -> `Workflows/Comics.md`

---

## Core Aesthetic

**Excalidraw Hand-Drawn** - Clean, approachable technical illustrations with:
- Slightly wobbly hand-drawn lines (NOT perfect vectors)
- Simple shapes with organic imperfections
- Consistent hand-lettered typography style
- Dark mode backgrounds with bright accents

**Full aesthetic documentation:** `$PAI_DIR/skills/Art/Aesthetic.md`
