Analyzes and optimizes Dockerfiles to reduce image size, improve build time, and enhance security. Use when optimizing Docker images, reducing build times, or improving Dockerfile structure.
Docker containerization patterns for Python/React projects. Use when creating or modifying Dockerfiles, optimizing image size, setting up Docker Compose for local development, or hardening container security. Covers multi-stage builds for Python (python:3.12-slim) and React (node:20-alpine -> nginx:alpine), layer optimization, .dockerignore, non-root user, security scanning with Trivy, Docker Compose for dev (backend + frontend + PostgreSQL + Redis), and image tagging strategy. Does NOT cover deployment orchestration (use deployment-pipeline).

Batch optimize images for web delivery. Converts to WebP, generates multiple sizes, and creates blur placeholders.
This skill should be used when the user asks to "optimize images", "compress images", "reduce image file size", "make images smaller", "optimize PNGs", "optimize JPEGs", "speed up website images", "reduce bundle size images", or needs help with image compression for web projects. Provides workflows and scripts for batch image optimization using sharp.
