 ## Blueprints
 
-Blueprints provide templates for creating events.
+Blueprints are factory functions that create Nostr events with automatic tag extraction and proper NIP compliance. They eliminate manual tag building and reduce boilerplate code significantly.
+
+### Key Benefits
+
+1. **Automatic Tag Extraction**: Blueprints automatically extract hashtags (#word), mentions (nostr:npub), and event quotes (nostr:note/nevent) from text content
+2. **NIP Compliance**: Each blueprint follows the correct NIP specifications for its event type
+3. **Less Code**: Replace 50-100 lines of manual tag building with 5-10 lines
+4. **Type Safety**: Full TypeScript support with proper types for all options
+5. **Maintainable**: Centralized event building logic that's easier to update
+
+### Using Blueprints
 
 ```typescript
 import { EventFactory } from 'applesauce-core/event-factory';
 import { NoteBlueprint } from 'applesauce-common/blueprints';
 
-const factory = new EventFactory({ signer });
-
-// Create a note using blueprint
-const draft = await factory.build(NoteBlueprint({
-  content: 'Hello Nostr!',
-  tags: [['t', 'nostr']]
-}));
+const factory = new EventFactory();
+factory.setSigner(signer);
 
+// Create event from blueprint
+const draft = await factory.create(NoteBlueprint, content, options);
 const event = await factory.sign(draft);
 ```
 
+### NoteBlueprint (Kind 1)
+
+Creates short text notes with automatic hashtag, mention, and quote extraction.
+
+**What it handles automatically:**
+- Extracts `#hashtags` from content → `t` tags
+- Extracts `nostr:npub...` mentions → `p` tags
+- Extracts `nostr:note...` and `nostr:nevent...` quotes → `q` tags (NIP-18)
+- Adds custom emoji tags (NIP-30)
+
+```typescript
+import { NoteBlueprint } from 'applesauce-common/blueprints';
+
+// Simple note
+const draft = await factory.create(
+  NoteBlueprint,
+  'Hello #nostr! Check out nostr:npub1abc...',
+  {}
+);
+
+// With custom emojis
+const draft = await factory.create(
+  NoteBlueprint,
+  'Hello :rocket:!',
+  {
+    emojis: [{ shortcode: 'rocket', url: 'https://example.com/rocket.png' }]
+  }
+);
+
+// The blueprint automatically adds:
+// - ["t", "nostr"] for #nostr
+// - ["p", "decoded-pubkey"] for the npub mention
+// - ["emoji", "rocket", "https://example.com/rocket.png"] for custom emoji
+```
+
+**Options:**
+- `emojis?: Array<{ shortcode: string; url: string }>` - Custom emojis (NIP-30)
+- `contentWarning?: boolean | string` - Content warning tag
+
+**Before/After Example:**
+```typescript
+// ❌ BEFORE: Manual tag building (~70 lines)
+const hashtags = content.match(/#(\w+)/g)?.map(tag => tag.slice(1)) || [];
+const mentionRegex = /nostr:(npub1[a-z0-9]+)/g;
+const mentions = [];
+let match;
+while ((match = mentionRegex.exec(content)) !== null) {
+  try {
+    const { data } = nip19.decode(match[1]);
+    mentions.push(data);
+  } catch (e) { /* ignore */ }
+}
+// ... more extraction logic ...
+draft.tags = [
+  ...hashtags.map(t => ['t', t]),
+  ...mentions.map(p => ['p', p]),
+  // ... more tags ...
+];
+
+// ✅ AFTER: Blueprint handles everything
+const draft = await factory.create(NoteBlueprint, content, { emojis });
+```
+
+### NoteReplyBlueprint (Kind 1 Reply)
+
+Creates threaded note replies following NIP-10 conventions.
+
+**What it handles automatically:**
+- Extracts root event from parent's tags (NIP-10)
+- Adds proper `e` tags with markers (root, reply)
+- Copies `p` tags from parent for notifications
+- Extracts hashtags, mentions, and quotes from content
+- Uses `q` tags for quotes instead of `e` tags (correct semantic)
+
+```typescript
+import { NoteReplyBlueprint } from 'applesauce-common/blueprints';
+
+// Reply to a note
+const parentEvent = await eventStore.event(parentId).toPromise();
+
+const draft = await factory.create(
+  NoteReplyBlueprint,
+  parentEvent,
+  'Great point! #bitcoin',
+  {
+    emojis: [{ shortcode: 'fire', url: 'https://example.com/fire.png' }]
+  }
+);
+
+// The blueprint automatically:
+// 1. Finds root from parent's tags (if parent is also a reply)
+// 2. Adds ["e", rootId, relay, "root"]
+// 3. Adds ["e", parentId, relay, "reply"]
+// 4. Copies all ["p", ...] tags from parent
+// 5. Extracts #bitcoin → ["t", "bitcoin"]
+// 6. Adds emoji tag
+```
+
+**Options:**
+- `emojis?: Array<{ shortcode: string; url: string }>` - Custom emojis
+- `contentWarning?: boolean | string` - Content warning
+
+**Before/After Example:**
+```typescript
+// ❌ BEFORE: Manual NIP-10 threading (~95 lines)
+const parentRefs = getNip10References(parentEvent);
+const rootId = parentRefs.root?.e || parentEvent.id;
+const rootRelay = parentRefs.root?.relay || '';
+
+draft.tags = [
+  ['e', rootId, rootRelay, 'root'],
+  ['e', parentEvent.id, '', 'reply'],
+];
+
+// Copy p-tags from parent
+const parentPTags = parentEvent.tags.filter(t => t[0] === 'p');
+draft.tags.push(...parentPTags);
+if (!parentPTags.some(t => t[1] === parentEvent.pubkey)) {
+  draft.tags.push(['p', parentEvent.pubkey]);
+}
+// ... hashtag extraction ...
+// ... mention extraction ...
+
+// ✅ AFTER: Blueprint handles NIP-10 threading
+const draft = await factory.create(
+  NoteReplyBlueprint,
+  parentEvent,
+  content,
+  { emojis }
+);
+```
+
+### ReactionBlueprint (Kind 7)
+
+Creates reactions to events (likes, custom emoji reactions).
+
+**What it handles automatically:**
+- Adds `e` tag pointing to reacted event
+- Adds `k` tag for event kind
+- Adds `p` tag for event author
+- Handles custom emoji reactions (`:shortcode:` format)
+- Supports both string emoji and Emoji objects
+
+```typescript
+import { ReactionBlueprint } from 'applesauce-common/blueprints';
+
+// Simple like (+ emoji)
+const draft = await factory.create(ReactionBlueprint, messageEvent, '+');
+
+// Custom emoji reaction
+const draft = await factory.create(
+  ReactionBlueprint,
+  messageEvent,
+  {
+    shortcode: 'rocket',
+    url: 'https://example.com/rocket.png'
+  }
+);
+
+// String emoji
+const draft = await factory.create(ReactionBlueprint, messageEvent, '🚀');
+
+// The blueprint automatically adds:
+// - ["e", messageEvent.id]
+// - ["k", messageEvent.kind.toString()]
+// - ["p", messageEvent.pubkey]
+// For custom emoji: ["emoji", "rocket", "url"]
+```
+
+**Options:**
+- Second parameter: `emoji?: string | { shortcode: string; url: string }`
+
+**Before/After Example:**
+```typescript
+// ❌ BEFORE: Manual reaction building (~15 lines per adapter)
+draft.kind = 7;
+draft.content = typeof emoji === 'string' ? emoji : `:${emoji.shortcode}:`;
+draft.tags = [
+  ['e', messageEvent.id],
+  ['k', messageEvent.kind.toString()],
+  ['p', messageEvent.pubkey],
+];
+if (typeof emoji === 'object') {
+  draft.tags.push(['emoji', emoji.shortcode, emoji.url]);
+}
+
+// ✅ AFTER: Blueprint handles reactions
+const draft = await factory.create(ReactionBlueprint, messageEvent, emoji);
+```
+
+### GroupMessageBlueprint (Kind 9 - NIP-29)
+
+Creates NIP-29 group chat messages.
+
+**What it handles automatically:**
+- Adds `h` tag with group ID
+- Extracts hashtags, mentions, and quotes from content
+- Adds custom emoji tags
+- Handles message threading with `previous` field
+
+```typescript
+import { GroupMessageBlueprint } from 'applesauce-common/blueprints';
+
+// Send message to NIP-29 group
+const draft = await factory.create(
+  GroupMessageBlueprint,
+  { id: groupId, relay: relayUrl },
+  'Hello group! #welcome',
+  {
+    previous: [], // Array of previous message events for threading
+    emojis: [{ shortcode: 'wave', url: 'https://example.com/wave.png' }]
+  }
+);
+
+// The blueprint automatically adds:
+// - ["h", groupId]
+// - ["t", "welcome"] for #welcome hashtag
+// - ["emoji", "wave", "url"] for custom emoji
+```
+
+**Options:**
+- `previous?: NostrEvent[]` - Previous messages for threading (required, use `[]` if no threading)
+- `emojis?: Array<{ shortcode: string; url: string }>` - Custom emojis
+
+**Note:** The `previous` field is required by the type, but can be an empty array if you don't need threading.
+
+### DeleteBlueprint (Kind 5 - NIP-09)
+
+Creates event deletion requests.
+
+**What it handles automatically:**
+- Adds `e` tags for each event to delete
+- Sets proper kind and content format
+- Adds optional reason in content
+
+```typescript
+import { DeleteBlueprint } from 'applesauce-common/blueprints';
+
+// Delete single event
+const draft = await factory.create(
+  DeleteBlueprint,
+  [eventToDelete],
+  'Accidental post'
+);
+
+// Delete multiple events
+const draft = await factory.create(
+  DeleteBlueprint,
+  [event1, event2, event3],
+  'Cleaning up old posts'
+);
+
+// Without reason
+const draft = await factory.create(DeleteBlueprint, [event], '');
+
+// The blueprint automatically:
+// - Sets kind to 5
+// - Adds ["e", eventId] for each event
+// - Sets content to reason (or empty)
+```
+
+**Parameters:**
+- `events: (string | NostrEvent)[]` - Events to delete (IDs or full events)
+- `reason?: string` - Optional deletion reason
+
+### Adding Custom Tags
+
+Blueprints handle common tags automatically, but you can add custom tags afterward:
+
+```typescript
+// Create with blueprint
+const draft = await factory.create(NoteBlueprint, content, { emojis });
+
+// Add custom tags not handled by blueprint
+draft.tags.push(['client', 'grimoire', '31990:...']);
+draft.tags.push(['a', `${kind}:${pubkey}:${identifier}`]);
+
+// Add NIP-92 imeta tags for blob attachments
+for (const blob of blobAttachments) {
+  draft.tags.push(['imeta', `url ${blob.url}`, `x ${blob.sha256}`, ...]);
+}
+
+// Sign the modified draft
+const event = await factory.sign(draft);
+```
+
+### Protocol-Specific Tag Additions
+
+Some protocols require additional tags beyond what blueprints provide:
+
+```typescript
+// NIP-29: Add q-tag for replies (not in blueprint yet)
+const draft = await factory.create(GroupMessageBlueprint, group, content, options);
+if (replyToId) {
+  draft.tags.push(['q', replyToId]);
+}
+
+// NIP-53: Add a-tag for live activity context
+const draft = await factory.create(ReactionBlueprint, messageEvent, emoji);
+draft.tags.push(['a', liveActivityATag, relay]);
+```
+
+### Available Blueprints
+
+All blueprints from `applesauce-common/blueprints`:
+
+- **NoteBlueprint** - Kind 1 short text notes
+- **NoteReplyBlueprint** - Kind 1 threaded replies (NIP-10)
+- **ReactionBlueprint** - Kind 7 reactions (NIP-25)
+- **GroupMessageBlueprint** - Kind 9 group messages (NIP-29)
+- **DeleteBlueprint** - Kind 5 deletion requests (NIP-09)
+- **MetadataBlueprint** - Kind 0 profile metadata
+- **ContactsBlueprint** - Kind 3 contact lists
+- **ArticleBlueprint** - Kind 30023 long-form articles (NIP-23)
+- **HighlightBlueprint** - Kind 9802 highlights (NIP-84)
+- **ZapRequestBlueprint** - Kind 9734 zap requests (NIP-57)
+- And more - check `node_modules/applesauce-common/dist/blueprints/`
+
+### Best Practices
+
+1. **Always use blueprints** when creating standard event types - they handle NIPs correctly
+2. **Add custom tags after** blueprint creation for app-specific metadata
+3. **Don't extract tags manually** - let blueprints handle hashtags, mentions, quotes
+4. **Use proper emoji format** - blueprints expect `{ shortcode, url }` objects
+5. **Check blueprint source** - when in doubt, read the blueprint code for exact behavior
+
 ## Operations
 
 Operations modify existing events.

+## EventFactory
+
+### Overview
+
+The `EventFactory` class (moved to `applesauce-core/event-factory` in v5) provides a unified API for creating and signing Nostr events using blueprints.
+
+```typescript
+import { EventFactory } from 'applesauce-core/event-factory';
+
+// Create factory
+const factory = new EventFactory();
+
+// Set signer (required for signing)
+factory.setSigner(signer);
+
+// Optional context
+factory.setClient({ name: 'grimoire', address: { pubkey, identifier } });
+```
+
+### Creating Events with Blueprints
+
+Blueprints are templates for event creation. See the **applesauce-common** skill for detailed blueprint documentation.
+
+```typescript
+import { NoteBlueprint, NoteReplyBlueprint } from 'applesauce-common/blueprints';
+
+// Create a note
+const draft = await factory.create(
+  NoteBlueprint,
+  'Hello #nostr!',
+  { emojis: [{ shortcode: 'wave', url: 'https://...' }] }
+);
+
+// Sign the draft
+const event = await factory.sign(draft);
+
+// Or combine: create and sign
+const event = await factory.sign(
+  await factory.create(NoteBlueprint, content, options)
+);
+```
+
+### Factory Methods
+
+```typescript
+// Create from blueprint
+const draft = await factory.create(Blueprint, ...args);
+
+// Sign event template
+const event = await factory.sign(draft);
+
+// Stamp (add pubkey without signing)
+const unsigned = await factory.stamp(draft);
+
+// Build with operations
+const draft = await factory.build(template, ...operations);
+
+// Modify existing event
+const modified = await factory.modify(event, ...operations);
+```
+
+### Using with Actions
+
+EventFactory integrates seamlessly with the action system:
+
+```typescript
+import accountManager from '@/services/accounts';
+import { EventFactory } from 'applesauce-core/event-factory';
+import { NoteBlueprint } from 'applesauce-common/blueprints';
+
+const account = accountManager.active;
+const signer = account.signer;
+
+const factory = new EventFactory();
+factory.setSigner(signer);
+
+// Create and sign
+const draft = await factory.create(NoteBlueprint, content, options);
+const event = await factory.sign(draft);
+
+// Publish
+await pool.publish(relays, event);
+```
+
+### Common Patterns
+
+**Creating with custom tags:**
+```typescript
+// Let blueprint handle automatic extraction
+const draft = await factory.create(NoteBlueprint, content, { emojis });
+
+// Add custom tags afterward
+draft.tags.push(['client', 'grimoire', '31990:...']);
+draft.tags.push(['imeta', `url ${blob.url}`, `x ${blob.sha256}`]);
+
+// Sign
+const event = await factory.sign(draft);
+```
+
+**Error handling:**
+```typescript
+try {
+  const draft = await factory.create(NoteBlueprint, content, options);
+  const event = await factory.sign(draft);
+  await pool.publish(relays, event);
+} catch (error) {
+  if (error.message.includes('User rejected')) {
+    // Handle rejection
+  } else {
+    // Handle other errors
+  }
+}
+```
+
+**Optimistic updates:**
+```typescript
+// Create and sign
+const event = await factory.sign(
+  await factory.create(NoteBlueprint, content, options)
+);
+
+// Add to local store immediately
+eventStore.add(event);
+
+// Publish in background
+pool.publish(relays, event).catch(err => {
+  // Remove from store on failure
+  eventStore.remove(event.id);
+});
+```
+
