Bash/Zsh wrapper that overrides claude to require an explicit workspace argument and automatically maps it to ~/.claude/settings.<workspace>.json, failing if no workspace or matching settings file is provided while transparently forwarding all additional CLI arguments.

claude-workspaces.sh

claude() {
  if [[ $# -lt 1 ]]; then
    echo "Usage: claude <workspace> [args...]" >&2
    return 1
  fi

  local workspace="$1"
  shift

  local settings_file="$HOME/.claude/settings.${workspace}.json"

  if [[ ! -f "$settings_file" ]]; then
    echo "Error: Settings file not found: $settings_file" >&2
    return 1
  fi

  command claude --settings "$settings_file" "$@"
}
