# XMTP reactions

Send and receive emoji reactions, including thinking indicator patterns.

## When to apply

Reference these guidelines when:
- Reacting to user messages with emoji
- Showing processing/thinking state
- Receiving and handling reactions
- Implementing acknowledgment patterns

## Rule categories by priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Send | HIGH | `send-` |
| 2 | Receive | HIGH | `receive-` |
| 3 | Patterns | MEDIUM | `patterns-` |

## Quick reference

### Send (HIGH)
- `send-reaction` - Send emoji reactions to messages

### Receive (HIGH)
- `receive-reaction` - Handle incoming reactions

### Patterns (MEDIUM)

## Quick start

```typescript
// Send a reaction
await ctx.conversation.sendReaction({
  reference: ctx.message.id,
  action: "added",
  content: "👍",
  schema: "unicode",
});

// Thinking indicator pattern
await ctx.conversation.sendReaction({
  reference: ctx.message.id,
  action: "added",
  content: "⏳",
  schema: "unicode",
});

// Process...

await ctx.conversation.sendReaction({
  reference: ctx.message.id,
  action: "removed",
  content: "⏳",
  schema: "unicode",
});
```
