About this skill
Image Optimizer
Your images are 5MB each and nobody noticed until Lighthouse screamed. This tool scans your images and tells you exactly what to optimize.
One command. Zero config. Just works.
Quick Start
npx ai-image-optimize ./public/images/
What It Does
- Scans image directories for optimization opportunities
- Identifies oversized images
- Suggests format conversions (PNG to WebP, etc.)
- Recommends responsive image strategies
Usage Examples
# Scan images directory
npx ai-image-optimize ./public/images/
# Scan assets folder
npx ai-image-optimize ./assets/
# Get detailed report
npx ai-image-optimize ./public/ --verbose
Best Practices
- Use WebP - smaller than PNG/JPEG with same quality
- Serve responsive images - don't send desktop images to mobile
- Lazy load below the fold - defer loading offscreen images
- Compress aggressively - 80% quality is usually fine
When to Use This
- Lighthouse says images are too big
- Page load times are slow
- Want to audit image usage
- Planning an optimization sprint

pdf-to-markdown
aliceisjustplaying
Convert entire PDF documents to clean, structured Markdown for full context loading. Use this skill when the user wants to extract ALL text from a PDF into context (not grep/search), when discussing or analyzing PDF content in full, when the user mentions "load the whole PDF", "bring the PDF into context", "read the entire PDF", or when partial extraction/grepping would miss important context. This is the preferred method for PDF text extraction over page-by-page or grep approaches.

This skill should be used when working on Godot Engine projects. It provides specialized knowledge of Godot's file formats (.gd, .tscn, .tres), architecture patterns (component-based, signal-driven, resource-based), common pitfalls, validation tools, code templates, and CLI workflows. The `godot` command is available for running the game, validating scripts, importing resources, and exporting builds. Use this skill for tasks involving Godot game development, debugging scene/resource files, implementing game systems, or creating new Godot components.
nano-banana-pro
garg-aayush
Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
