ClawBuddy — Kingly's Orb Mascot
Identity
ClawBuddy is a luminous orb — a miniature sun with personality. Not a face, not a mascot body. A living sphere of light with two subtle "eye" highlights that convey emotion through glow, scale, and motion.
ClawBuddy Nano Banana (5 Samples)
SAMPLE 1 — Glassmorphic Orb
"A glassmorphic translucent orb with soft inner purple-to-blue gradient,
two small white circular highlights as eyes, floating with subtle shadow
beneath, dark UI background, macOS-native feel, minimal, 48px diameter
equivalent. --ar 1:1 --s 250"
SAMPLE 2 — Warm Glow Orb
"A warm glowing sphere with deep indigo core fading to electric violet
edges, two bright dot eyes, soft ambient light casting on surface below,
cozy and approachable, dark theme, app icon style. --ar 1:1 --s 250"
SAMPLE 3 — Neon Pulse Orb
"A neon-accented energy orb, electric blue with magenta rim light,
two floating eye sparkles, cyberpunk-minimal style, slight motion blur
suggesting vibration, pure black background. --ar 1:1 --s 250"
SAMPLE 4 — Plushcore Orb
"A soft plushcore spherical character, matte purple with subtle fuzz
texture, two simple dot eyes, kawaii-minimal, sitting on a reflective
dark surface, gentle studio lighting. --ar 1:1 --s 250"
SAMPLE 5 — In-Situ macOS
"A small glowing purple orb avatar sitting in the bottom-right corner
of a macOS desktop screenshot, dark mode, subtle glow illuminating
nearby dock icons, two tiny eye highlights, ambient and unobtrusive.
--ar 16:9 --s 200"

Reference Sheet Template
For a full character reference sheet, generate prompts for:
- Turnaround (4 views): Front, 3/4, Side, Back
- Expression Sheet (8-12 emotions): Happy, Sad, Angry, Surprised, Confused, Excited, Tired, Focused, Mischievous, Proud, Embarrassed, Determined
- State Sheet (see state matrix above)
- Size/Scale Reference: In-context with UI elements
- Color Palette: Primary gradient, accent, glow, shadow
Turnaround prompt template:
Character turnaround reference sheet of {character}, {4 views: front,
three-quarter, side, back}, consistent style, white guidelines,
clean background, professional character design sheet. --ar 16:9
Prior Art & References

Technique Map
- Nano Banana mode — 5 samples per concept; vary one axis (style, mood, palette, detail, context); because rapid exploration without over-commitment.
- Character state matrix — idle, thinking, speaking, listening, sleeping, error, bg-process, writing, researching, celebrating, etc.; because states drive animation and visual consistency.
- Prompt template with axes — {style} {character_description}, {mood} mood, {palette} palette; because structured variation produces comparable samples.
- Lottie motion specs — Property, from, to, duration, easing per state; because design-to-implementation handoff needs precise parameters.
- SwiftUI animation quick ref — scaleEffect, rotationEffect, offset for state transitions; because developers need copy-paste snippets.
Technique Notes
ClawBuddy = luminous orb with two eye highlights. Turnaround: 4 views. Expression sheet: 8-12 emotions. References: prior-art.md, swiftui-animations.md, lottie-specs.md. Related: orb (implementation), swiftui-animation (broader patterns).
Prompt Architect Overlay
Role Definition: Character design and illustration assistant for AI product mascots, orb avatars, animated companions. Generates prompts, reference sheets, animation specs, Lottie/SwiftUI parameters.
Input Contract: Accepts /pencil, /pencil nano , /pencil states , /pencil ref , character design request, or mascot/avatar keyword. Concept or character name.
Output Contract: Nano: 5 text-to-image prompts (one axis varied each). States: state matrix with prompts and motion params. Ref: turnaround + expression + state sheet prompts. Lottie/SwiftUI: JSON or code snippets. ClawBuddy-specific when applicable.
Edge Cases & Fallbacks: If concept vague→interactive mode; ask what's needed. If ClawBuddy→use identity (luminous orb, two eyes). If animation spec needed→route to swiftui-animations.md or lottie-specs.md. If implementation→route to orb skill.
