Currently each programmer writing a bot for Google Wave is able to write whatever they want, sometimes providing support, but using their own, custom syntax. Having a set of commands which all (or many) bots implement would make the user experience far better, as users would then be able to easily find out how to use the bot, or where to find additional help.
botName@appspot.com /? //see /help
botName@appspot.com /help //brings up a list of commands available
botName@appspot.com /about //displays a summary of what this robot does
botName@appspot.com /devsite //provides a link to the developer’s site
botName@appspot.com /mode private //the bot’s responses are only shown to the person who invited it
botName@appspot.com /mode public //everyone in the wave sees the bot’s responses
I’ve also made a summary of this post available on the Google Wave Bots site. Please can you post any responses to that site, as this will allow all communications to be kept in the same place.
