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. |
