AS 关键字定义多个阶段。在第一阶段进行源码编译、依赖安装；在第二阶段仅拷贝最终产物（如编译后的二进制文件或静态资源）到轻量级基础镜像（如 Alpine 或 Distroless）中。RUN 指令，清理构建过程中的临时文件（如 npm cache clean, apt-get clean）。package.json, go.mod），运行安装命令，最后再拷贝源代码。这能显著提高后续构建速度。alpine, slim 版本，或 Google 的 distroless 镜像以降低攻击面。.git, node_modules, tests, docs），减小上传给 Docker daemon 的上下文体积。depends_on 及其 condition: service_healthy（结合 healthcheck）确保依赖服务就绪后再启动主应用。docker-compose.override.yml 或 env_file 实现不同环境的差异化配置。bridge（默认隔离）、host（无隔离，高性能）、none 及自定义 overlay 网络。bind mounts（挂载主机目录，常用于开发）和 named volumes（由 Docker 管理，常用于生产）。USER 指令切换到非特权用户。docker scan (Snyk), Trivy 或 Clair 检查镜像中的已知 CVE。--cpus, --memory，防止容器资源耗尽攻击（DoS）。--cache-from 提升流水线中的镜像构建速度。docker login, push 流程。# 查看容器资源占用 (CPU, Memory, Network)

Multi-agent collaboration plugin that spawns N parallel subagents competing on the same task via git worktree isolation. Agents work independently, results are evaluated by metric or LLM judge, and the best branch is merged. Use when: user wants multiple approaches tried in parallel — code optimization, content variation, research exploration, or any task that benefits from parallel competition. Requires: a git repo.
Design production-grade multi-agent orchestration systems. Covers five core patterns (sequential pipeline, parallel fan-out/fan-in, hierarchical delegation, event-driven, consensus), platform-specific implementations, handoff protocols, state management, error recovery, context window budgeting, and cost optimization.
App Store Optimization toolkit for researching keywords, optimizing metadata, and tracking mobile app performance on Apple App Store and Google Play Store.
