+# Desktop Pet Creator
+
+Create pixel-art chibi desktop pet companions for OpenWork's floating pet window.
+Given any character name, generate a complete pet package with animated spritesheet
+and place it in `~/.qwen/pets/` where OpenWork auto-discovers it.
+
+## Workflow
+
+### Step 1: Identify the Character
+
+Ask the user who they want as their desktop pet if not already specified.
+Then research the character's visual appearance:
+
+- **Team/organization colors** (e.g., McLaren papaya orange, Ferrari red)
+- **Outfit/uniform** (racing suit, school uniform, armor, etc.)
+- **Distinguishing features** (hair color/style, accessories, number, helmet)
+- **Personality traits** (for animation style — energetic, calm, goofy, serious)
+- **Iconic items** (steering wheel, lightsaber, guitar, etc.)
+
+Use web search if needed to gather visual reference. For well-known characters
+(F1 drivers, popular anime, etc.), rely on training knowledge.
+
+### Step 2: Design the Color Palette
+
+Define 8-12 colors for the character:
+
+| Color Role | Example (F1 Driver) | Example (Anime Character) |
+|---|---|---|
+| Primary outfit | Team color (papaya) | Uniform color (navy) |
+| Outfit dark | Darker shade | Darker shade |
+| Outfit light | Lighter shade | Lighter shade |
+| Skin | Warm skin tone | Skin tone |
+| Skin dark | Shadow skin | Shadow skin |
+| Hair | Character hair color | Character hair color |
+| Accent | Number/logo color | Eye color / accessory |
+| Shoe | Dark grey/black | Character shoe color |
+
+**Important:** All colors must be distinct and work at small pixel scale (3x = 9px details).
+
+### Step 3: Generate the Spritesheet
+
+Use the template script at `scripts/gen_spritesheet.py` as a starting point.
+The script generates a **1536×1872 pixel RGBA spritesheet** (8 columns × 9 rows,
+192×208 px cells) — the exact format OpenWork expects.
+
+**Run it like this:**
+```bash
+python3 <skill_dir>/scripts/gen_spritesheet.py \
+  --output ~/.qwen/pets/<character_id>/spritesheet.webp \
+  --config '{"name":"...","colors":{...},"features":{...}}'
+```
+
+Or copy and customize the script for characters that need unique visual elements
+not covered by the parameterized version.
+
+**The 9 animation rows are:**
+
+| Row | State | Description |
+|---|---|---|
+| 0 | idle | Breathing + blinking (8 frames) |
+| 1 | running-right | Running to the right (8 frames) |
+| 2 | running-left | Running to the left (8 frames) |
+| 3 | waving | Waving at user (8 frames) |
+| 4 | jumping | Jumping celebration (8 frames) |
+| 5 | failed | Sad/collapsed on error (8 frames) |
+| 6 | waiting | Idle tapping (8 frames) |
+| 7 | running | Generic running (8 frames) |
+| 8 | review | Thinking/examining (8 frames) |
+
+### Step 4: Create pet.json
+
+Write the manifest to `~/.qwen/pets/<character_id>/pet.json`:
+
+```json
+{
+  "id": "<character_id>",
+  "displayName": "<Display Name>",
+  "description": "<Short description — who is this character?>",
+  "spritesheetPath": "spritesheet.webp"
+}
+```
+
+Rules:
+- `id`: lowercase, no spaces, URL-safe (e.g., `piastri`, `satoru`, `goku`)
+- `displayName`: The name shown in the UI (e.g., "Piastri", "五条悟", "悟空")
+- `description`: One short sentence describing the character
+
+### Step 5: Verify and Activate
+
+1. Confirm the files exist:
+   ```bash
+   ls -lh ~/.qwen/pets/<character_id>/
+   ```
+
+2. Open the spritesheet in Preview for the user to check:
+   ```bash
+   open ~/.qwen/pets/<character_id>/spritesheet.webp
+   ```
+
+3. Tell the user to activate:
+   > Open **OpenWork → Settings → Appearance → Pet Companion**,
+   > click **Refresh**, then select **<Display Name>**.
+
+## Character Design Guidelines
+
+### Chibi Proportions
+- **Head**: ~40% of total height (big head = cute)
+- **Body**: ~30% of total height
+- **Legs**: ~25% of total height
+- **Scale**: Each "pixel" in the art = 3×3 actual pixels (scale=3)
+- **Character center**: approximately (96, 124) within the 192×208 cell
+
+### Drawing Order (back to front)
+1. Legs (behind body)
+2. Body / outfit
+3. Arms
+4. Head shape
+5. Hair (back layer)
+6. Hair (front/top layer)
+7. Face features (eyes, mouth, expression)
+8. Accessories (hat, helmet, glasses, etc.)
+9. Foreground details (number, logo, badge)
+
+### Animation Tips
+- **Idle**: subtle Y bob (0 to -2px) + blink every 3rd-4th frame
+- **Running**: alternating leg offset (±4px), body tilt (±2px), arm swing
+- **Waving**: one arm raised high, alternating frames
+- **Jumping**: Y offset curve (0 → -30 → 0), arms up
+- **Failed**: body tilt increases, then collapse to sitting pose
+- **Happy expression**: curved eyes (∧ shape), blush marks on cheeks
+- **Sad expression**: straight eyebrows, downturned mouth
+
+### Headgear Variants
+The template supports several headgear types. Set via `features.headgear`:
+- `cap` — baseball cap with brim (default for F1 drivers)
+- `helmet` — full racing helmet with visor
+- `none` — no headgear (just hair)
+- `hat` — generic hat
+- `hood` — hooded outfit
+- `crown` — royal crown
+- `horns` — devil/dragon horns
+- `ears` — animal ears (cat, dog, etc.)
+- `halo` — angel halo
+- `headband` — ninja/sports headband
+
+### Special Features
+Set via `features.extras` (list):
+- `glasses` — round or rectangular glasses
+- `scarf` — neck scarf
+- `tail` — animal tail
+- `wings` — small wings on back
+- `number` — chest number (set `features.number` to the number string)
+- `logo` — chest badge/logo area
+- `sweat_drop` — anime sweat drop (in waiting/failed states)
+
+## Example Characters
+
+### F1 Driver (e.g., Piastri, Norris, Verstappen)
+```json
+{
+  "colors": {
+    "outfit": [255, 135, 32],
+    "outfit_dark": [220, 110, 20],
+    "outfit_light": [255, 170, 80],
+    "hair": [120, 80, 40],
+    "number": [30, 30, 30]
+  },
+  "features": {
+    "headgear": "cap",
+    "number": "81",
+    "extras": ["logo"]
+  }
+}
+```
+
+### Anime Character (e.g., Gojo Satoru)
+```json
+{
+  "colors": {
+    "outfit": [30, 30, 50],
+    "outfit_dark": [20, 20, 35],
+    "outfit_light": [60, 60, 80],
+    "hair": [230, 230, 250],
+    "accent": [100, 180, 255]
+  },
+  "features": {
+    "headgear": "none",
+    "extras": ["glasses"]
+  }
+}
+```
+
+### Animal (e.g., Shiba Inu)
+```json
+{
+  "colors": {
+    "outfit": [220, 170, 100],
+    "outfit_dark": [180, 130, 70],
+    "outfit_light": [240, 200, 140],
+    "hair": [220, 170, 100],
+    "accent": [255, 255, 255]
+  },
+  "features": {
+    "headgear": "ears",
+    "extras": ["tail"]
+  }
+}
+```
+
+## Troubleshooting
+
+- **Pet not showing**: Click Refresh in Settings → Appearance → Pet Companion
+- **Colors look wrong**: Check that RGB values are tuples, not hex strings
+- **Spritesheet too large**: Must be under 5MB (webp lossless usually ~8-50KB)
+- **Animation jittery**: Ensure all 8 frames per row are visually distinct but not jarring
