Expert reference for the Dev Container ecosystem. Consult this skill whenever the user is setting up a dev container, configuring or debugging devcontainer.json, working in a Docker-based development environment, or asking about dev containers, GitHub Codespaces, DevPod, or Zed — even if they don't say "devcontainer" explicitly. Covers the full Dev Container spec, schema validation, tool-specific behaviors and limitations (VS Code, Cursor, Zed, Codespaces, CodeSandbox, Podman), Features and Templates (choosing, authoring, publishing), lifecycle scripts, environment variables, port forwarding, multi-container setups, and official best practices from containers.dev and devcontainers.github.io. Also use when the user is confused by container behavior that differs between tools, wants to write or publish a custom Feature, or needs to validate or debug a devcontainer.json.
Create reproducible development environments with Dev Containers, Nix flakes, and Devbox for consistent toolchains across teams. Use when onboarding developers, standardizing build environments, or eliminating "works on my machine" problems.
Creates devcontainers with Claude Code, language-specific tooling (Python/Node/Rust/Go), and persistent volumes. Use when adding devcontainer support to a project, setting up isolated development environments, or configuring sandboxed Claude Code workspaces.
Diagnose devcontainer configuration problems and guide development environment setup. This skill should be used when the user asks to 'set up devcontainer', 'fix container startup', 'configure VS Code dev container', 'Codespaces setup', or has Docker development environment issues. Keywords: devcontainer, docker, VS Code, Codespaces, container, development environment, Dockerfile.
Guide for setting up secured VS Code dev containers for coding agents. Use when creating or hardening a DevContainer to sandbox Claude Code or other coding agents, configuring Docker socket proxies, handling VS Code IPC escape vectors, setting up git worktree support, or verifying security controls. Covers threat model, three-layer defence architecture, Node.js/pnpm setup, and verification testing.
