Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Reactions Choose reactions when lightweight feedback can safely remain attached to an existing item and does not require a written reply. Each reaction attaches to one named source item and does not create a separate conversation by itself. Slack developer docs document reaction target parameters, skin tone modifiers, already-reacted errors, access errors, and reaction_added event broadcast.
