How to standardize Claude Code dev environments: devcontainer.json, CI consistency, and team rollout
Add Anthropic's official Dev Container Feature (`ghcr.io/anthropics/devcontainer-features/claude-code:1.0`) to `.devcontainer/devcontainer.json` and three steps—write the config, rebuild the container, run `claude` to sign in—put every teammate's Claude Code behind the same container definition. The same definition feeds GitHub Codespaces and CI; a five-step rollout gets the whole team there.
