Agent Skills: Geometric Elements Generator

Generate decorative geometric elements (corners, lines, arcs, frames) with precise control over colors, gradients, and transparency. Use when creating design assets, slide decorations, or any vector-like graphics programmatically. Can also analyze reference images and recreate geometric patterns.

Description
Generate decorative geometric elements (corners, lines, arcs, frames) with precise control over colors, gradients, and transparency. Use when creating design assets, slide decorations, or any vector-like graphics programmatically. Can also analyze reference images and recreate geometric patterns.

Geometric Elements Generator

Create decorative geometric elements with code using Pixie-python.

Quick Start

# Install dependency (first time only)
pip install pixie-python

# Generate element (ask user for brand color or check their brand guidelines)
python .claude/skills/geometric-elements/scripts/generate.py corner-accent \
  --color "#HEX_COLOR" \
  --size 200 \
  --output media/output/corner.png

Important: Always ask user for brand colors or check their brand guidelines skill (e.g., /thepexcel-brand-guidelines) before generating.

Available Elements

| Element | Command | Description | |---------|---------|-------------| | Basic Shapes | shape | circle, star, heart, hexagon, arrow, etc. | | Corner Accent | corner-accent | L-shaped corner decoration | | Line Divider | line-divider | Horizontal divider with gradient | | Arc Accent | arc-accent | Curved arc | | Frame Border | frame-border | 4-corner bracket frame | | Pattern | pattern | Repeating dots/crosses/diamonds | | Mandala | mandala | Sacred geometry / complex patterns |

Common Options

| Option | Description | Default | |--------|-------------|---------| | --color | Primary color (hex) | #D4A84B | | --color2 | Secondary color for gradient | None | | --size | Element size in pixels | 200 | | --width | Canvas width | 400 | | --height | Canvas height | 400 | | --stroke | Stroke width | 4 | | --output | Output file path | output.png | | --gradient | linear or radial | None | | --opacity | 0.0-1.0 | 1.0 | | --fill | Fill shape (vs stroke) | False |

Examples

Basic Shapes

# Circle (stroke)
python scripts/generate.py shape --style circle --color "#HEX" --size 100 --stroke 3

# Star (filled)
python scripts/generate.py shape --style star --color "#HEX" --size 100 --sides 5 --fill

# Available: circle, ellipse, rectangle, square, rounded-rect, triangle,
#   polygon, star, diamond, ring, cross, arrow, heart, hexagon, octagon, crescent

Corner Accent

python scripts/generate.py corner-accent --color "#HEX" --size 150 --stroke 4

Gradient Line Divider

python scripts/generate.py line-divider --color "#HEX" --color2 "#FFFFFF" --gradient linear --width 800

Mandala (Sacred Geometry)

python scripts/generate.py mandala --color "#CCC" --bg "#0A0A0A" --size 400 --rings 8 --layers 4 --stroke 1.5

Custom Elements (On-the-fly)

For complex patterns not in predefined commands, write Python directly:

import pixie
import math

image = pixie.Image(400, 400)
paint = pixie.Paint(pixie.SOLID_PAINT)
paint.color = pixie.Color(0.83, 0.66, 0.29, 1.0)  # RGB 0-1 range

ctx = image.new_context()
ctx.stroke_style = paint
ctx.line_width = 2
ctx.stroke_segment(50, 50, 350, 350)

image.write_file("output.png")

→ Full API: references/pixie-api.md

From Reference Image

User can send reference images for Claude to analyze and recreate:

  1. User sends image — screenshot, design reference, pattern
  2. Claude analyzes — identifies shapes, colors, proportions
  3. Claude writes code — using pixie-python API
  4. Output — PNG ready to use

Tips for good reference: Clear image, geometric patterns (not photos), specify hex colors if needed.

Tips

  1. Transparent bg — All outputs have transparent background by default
  2. High DPI — Use --size 2x for retina displays
  3. Gradients — Combine --gradient linear with --color and --color2
  4. Brand colors — Always confirm with user or their brand guidelines first
