Easy Claude Code devcontainer workflows (github.com)

Smithclay’s new claudetainer tool auto-configures a Claude Code devcontainer so you can “code from anywhere” in under two minutes. It spins up an isolated devcontainer (using Anthropic’s official image) with a persistent shell session, hooks, slash commands, specialized sub-agents, and utilities like ccusage and gitui. Install via Homebrew, run claudetainer init [python|node|go|rust|shell], claudetainer up, claudetainer ssh, then launch claude inside a zellij/tmux multiplexer (or MOSH for mobile). It uses SSH key auth (passwordless), supports Docker Desktop on macOS, and integrates push notifications, mobile-optimized layouts, and GitHub-presets for sharing team configs. For AI/ML engineers this lowers friction for iterative model-assisted coding and remote collaboration: reproducible devcontainers + Anthropic’s runtime give environment parity and safer isolation, while automated quality-control hooks and sub-agents streamline code generation, review, and CI-style checks. Mobile-first features (MOSH + zellij, layouts, notifications) enable on-the-go interactions with Claude Code, and the CLI includes management and health commands (list, doctor, rm). The project is MIT-licensed, documents architecture/presets/testing, and builds on community hooks from existing Claude Code setups—making it easy to extend, audit, and adopt in team workflows.
