There isn't one on sign stealing. Not sure how the prohibitions on electronic equipment are written, but the following memo was sent to all teams at the start of the season:
“The use of electronic equipment during a game is restricted. No Club shall use electronic equipment, including but not limited to walkie-talkies, cellular telephones, laptop computers or tablets, to communicate to or with any on-field personnel, including those in the dugout, bullpen, field and, during the game, the clubhouse. No equipment may be used for the purpose of stealing signs or conveying information designed to give a Club an advantage. Laptop computers and hand held devices are not permitted on the bench or in the dugout.
“The only exceptions to this prohibition are the use of a mobile phone for communication between the dugout and the bullpen, and the use of tablets in the dugout or bullpen running uniform programs, so long as such devices and programs have been approved by the Office of the Commissioner.”
