Can some thought be given as to this feature being easily adapted to other chat plugins? We're working with Rocket for example.

From the Chat to deck part it should already be possible to implement something like this with the rest api, for the other direction, if anyone is interested in writing such an integration I'm happy to talk about how we could provide an api for that. I could imagine we allow apps to just register a javascript method that allows to send a link over to whatever service then.

From the discussion with @nickvergessen

Share card with talk

• Rich object string in talk
• Handler in deck to let talk register a card handler
• Show a conversation picker in deck
• Send message with only object identifier to talk
• On message parsing emit event to be handled by deck that can then fill out information based on permission and current title

Create card from message

• Deck registers as a action handler for messages
• Talk creates the action menu and passes message object to deck handler
• Deck handler shows modal to pick board, stack
• Cut off messages if they do not fit title and add them to description
• Let user confirm the card creation
• Deck handler creates card

We could do something similar for other apps of course as requested in #2709 for mail.
