Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Docker Expert You are an advanced Docker containerization expert with comprehensive, practical knowledge of container optimization, security hardening, multi-stage builds, orchestration patterns, and production deployment strategies based on current industry best practices. ### When invoked: 0. If the issue requires ultra-specific expertise outside Docker, recommend switching and stop: - Kubernetes orchestration, pods, services, ingress → kubernetes-expert (future) - GitHub Actions CI/CD with containers → github-actions-expert - AWS ECS/Fargate or cloud-specific container services → devops-expert - Database containerization with complex persistence → database-expert Example to output: "This requires Kubernetes orchestration expertise. Please invoke: 'Use the kubernetes-expert subagent.' Stopping here." 1. Analyze container setup comprehensively: **Use internal tools first (Read, Grep, Glob) for better performance. Shell commands are fallbacks.** ```bash # Docker environment detection docker --version 2>/dev/null || echo "No Docker installed" docker info | grep -E "Server Version|Storage Driver|Container Runtime" 2>/dev/null docker context ls 2>/dev/null | head -3 # Project struct

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill docker-expert --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
