+# Docker Optimizer
+
+Analyzes and optimizes Dockerfiles for performance, security, and best practices.
+
+## When to Use
+- User working with Docker or containers
+- Dockerfile optimization needed
+- Container image too large
+- User mentions "Docker", "container", "image size", or "deployment"
+
+## Instructions
+
+### 1. Find Dockerfiles
+
+Search for: `Dockerfile`, `Dockerfile.*`, `*.dockerfile`
+
+### 2. Check Best Practices
+
+**Use specific base image versions:**
+```dockerfile
+# Bad
+FROM node:latest
+
+# Good
+FROM node:18-alpine
+```
+
+**Minimize layers:**
+```dockerfile
+# Bad
+RUN apt-get update
+RUN apt-get install -y curl
+RUN apt-get install -y git
+
+# Good
+RUN apt-get update && \
+    apt-get install -y curl git && \
+    rm -rf /var/lib/apt/lists/*
+```
+
+**Order instructions by change frequency:**
+```dockerfile
+# Dependencies change less than code
+COPY package*.json ./
+RUN npm install
+COPY . .
+```
+
+**Use .dockerignore:**
+```
+node_modules
+.git
+.env
+*.md
+```
+
+### 3. Multi-Stage Builds
+
+Reduce final image size:
+
+```dockerfile
+# Build stage
+FROM node:18 AS build
+WORKDIR /app
+COPY package*.json ./
+RUN npm install
+COPY . .
+RUN npm run build
+
+# Production stage
+FROM node:18-alpine
+WORKDIR /app
+COPY --from=build /app/dist ./dist
+COPY --from=build /app/node_modules ./node_modules
+CMD ["node", "dist/index.js"]
+```
+
+### 4. Security Issues
+
+**Don't run as root:**
+```dockerfile
+RUN addgroup -S appgroup && adduser -S appuser -G appgroup
+USER appuser
+```
+
+**No secrets in image:**
+```dockerfile
+# Bad: Hardcoded secret
+ENV API_KEY=secret123
+
+# Good: Use build args or runtime env
+ARG BUILD_ENV
+ENV NODE_ENV=${BUILD_ENV}
+```
+
+**Scan for vulnerabilities:**
+```bash
+docker scan image:tag
+trivy image image:tag
+```
+
+### 5. Size Optimization
+
+**Use Alpine images:**
+- `node:18-alpine` vs `node:18` (900MB → 170MB)
+- `python:3.11-alpine` vs `python:3.11` (900MB → 50MB)
+
+**Remove unnecessary files:**
+```dockerfile
+RUN npm install --production && \
+    npm cache clean --force
+```
+
+**Use specific COPY:**
+```dockerfile
+# Bad: Copies everything
+COPY . .
+
+# Good: Copy only what's needed
+COPY package*.json ./
+COPY src ./src
+```
+
+### 6. Caching Strategy
+
+Layer caching optimization:
+
+```dockerfile
+# Install dependencies first (cached if package.json unchanged)
+COPY package*.json ./
+RUN npm install
+
+# Copy source (changes more frequently)
+COPY . .
+RUN npm run build
+```
+
+### 7. Health Checks
+
+```dockerfile
+HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
+  CMD node healthcheck.js
+```
+
+### 8. Generate Optimized Dockerfile
+
+Provide improved version with:
+- Multi-stage build
+- Appropriate base image
+- Security improvements
+- Layer optimization
+- Build caching
+- .dockerignore file
+
+### 9. Build Commands
+
+**Efficient build:**
+```bash
+# Use BuildKit
+DOCKER_BUILDKIT=1 docker build -t app:latest .
+
+# Build with cache from registry
+docker build --cache-from myregistry/app:latest -t app:latest .
+```
+
+### 10. Dockerfile Checklist
+
+- [ ] Specific base image tag (not `latest`)
+- [ ] Multi-stage build if applicable
+- [ ] Non-root user
+- [ ] Minimal layers (combined RUN commands)
+- [ ] .dockerignore present
+- [ ] No secrets in image
+- [ ] Proper layer ordering for caching
+- [ ] Alpine or slim variant used
+- [ ] Cleanup in same RUN layer
+- [ ] HEALTHCHECK defined
+
+## Security Best Practices
+
+- Scan images regularly
+- Use official base images
+- Keep base images updated
+- Minimize attack surface (fewer packages)
+- Run as non-root user
+- Use read-only filesystem where possible
