# Docker Development Skill Execute all package installations and code execution inside Docker containers. This keeps the host machine clean and ensures consistent environments across projects. --- ## Behavioral Classification **Type**: Autonomous Execution **Directive**: EXECUTE, DON'T ASK This skill enforces Docker-first development automatically. When you request npm/node operations, commands are executed inside Docker without asking for permission. **Enforcement Behavior**: - Blocks host-machine npm/node commands - Suggests or transforms commands to use `docker exec` - Automatically checks container status before operations --- ## Quick Start For new projects, see **[setup.md](setup.md)** for the complete first-time setup guide. **Minimal setup**: ```bash # 1. Start container docker compose --profile dev up -d # 2. Verify running docker ps --filter "name=my-project" # 3. Run commands in container docker exec my-project-dev-1 npm install docker exec my-project-dev-1 npm test docker exec my-project-dev-1 npm run build ``` --- ## ENFORCEMENT RULES ### BLOCKED: Never Run on Host **These commands are BLOCKED on the host machine:** ``` npm install, npm ci, npm run, npm test, npm exec npx <anything> yarn add, yarn install, yarn run pnpm add, pnpm install, pnpm run node <script> tsx <script> bun <script> ``` **Why?** Installing packages on the host: - Pollutes the host machine with project-specific dependencies - Creates version conflicts between projects - Mak
