1	# App Extensions Generator
2
3	Generate production app extension infrastructure -- Share Extensions for receiving content from other apps, Action Extensions for manipulating content in-place, Keyboard Extensions for custom input, and Safari Web Extensions for browser integration. Includes App Group data sharing between the host app and extensions.
4
5	## When This Skill Activates
6
7	Use this skill when the user:
8	- Asks to "add a share extension" or "share sheet extension"
9	- Wants to "receive content from other apps" or "accept shared content"
10	- Mentions "action extension" or "content manipulation extension"
11	- Wants to "add a custom keyboard" or "keyboard extension"
12	- Asks about "Safari extension" or "Safari web extension"
13	- Mentions "app extension" or "extension target" generically
14	- Wants to "share data between app and extension" or "App Groups"
15
16	## Pre-Generation Checks
17
18	### 1. Project Context Detection
19	- [ ] Check deployment target (iOS 16+ / macOS 13+)
20	- [ ] Check Swift version (requires Swift 5.9+)
21	- [ ] Identify project structure (find .xcodeproj or Package.swift)
22	- [ ] Identify source file locations
23
24	### 2. Existing Extension Detection
25	Search for existing extension targets:
26	```
27	Glob: */Extension/.swift, */Extension*/Info.plist
28	Grep: "NSExtensionPointIdentifier" or "NSExtensionPrincipalClass"
29	```
30
31	If existing extensions found:
32	- Ask if user wants to add another or modify existing
33	- Identify existing App Groups configuration
34
35	### 3. App Groups Detection
36	Check for existing App Groups setup:
37	```
38	Glob: */.entitlements
39	Grep: "com.apple.security.application-groups"
40	```
41
42	If App Groups exist, reuse the existing group identifier.
43
44	## Configuration Questions
45
46	Ask user via AskUserQuestion:
47
48	1. What type of extension?
49	- Share Extension (accept content from other apps, display share UI)
50	- Action Extension (manipulate content in-place -- transform text, edit images)
51	- Keyboard Extension (custom input keyboard with KeyboardViewController)
52	- Safari Web Extension (inject JavaScript/CSS into web pages)
53
54	2. What content types does it handle?
55	- Text (plain text, rich text)
56	- URLs (web links, deep links)
57	- Images (photos, screenshots)
58	- Files (documents, PDFs, archives)
59	- All (any content type)
60
61	3. Does the extension need to share data with the main app?
62	- Yes -- needs App Groups (shared UserDefaults, shared file container, shared Keychain)
63	- No -- extension is self-contained
64
65	## Generation Process
66
67	### Step 1: Read Templates
68	Read `templates.md` for production Swift code.
69
70	### Step 2: Create Extension Files
71	Based on extension type selected:
72
73	Share Extension:
74	1. `ShareViewController.swift` -- Main share extension view controller with content handling
75	2. `Info.plist` -- Extension configuration with activation rules
76
77	Action Extension:
78	3. `ActionViewController.swift` -- Action extension with content manipulation
79	4. `Info.plist` -- Extension configuration
80
81	Keyboard Extension:
82	5. `KeyboardViewController.swift` -- Custom keyboard with UIInputViewController
83	6. `Info.plist` -- Keyboard extension configuration
84
85	Safari Web Extension:
86	7. `SafariWebExtensionHandler.swift` -- Native message handler
87	8. `manifest.json` -- Web extension manifest
88	9. `content.js` -- Content script template
89
90	### Step 3: Create Shared Infrastructure
91	If data sharing selected:
92	10. `SharedDataManager.swift` -- App Group data sharing helper
93
94	### Step 4: Determine File Location
95	Extensions are separate targets:
96	- Share Extension -> `ShareExtension/`
97	- Action Extension -> `ActionExtension/`
98	- Keyboard Extension -> `KeyboardExtension/`
99	- Safari Web Extension -> `SafariWebExtension/`
100	- Shared code -> `Shared/` or within main app target
101
102	## Output Format
103
104	After generation, provide:
105
106	### Files Created
107

109	```

111	├── ShareViewController.swift # Main share extension view controller
112	└── Info.plist # Extension activation rules & config

116	```
117	ActionExtension/
118	├── ActionViewController.swift # Content manipulation controller
119	└── Info.plist # Extension activation rules & config

123	```
124	KeyboardExtension/
125	├── KeyboardViewController.swift # UIInputViewController subclass
126	└── Info.plist # Keyboard extension config
127	```

129	Safari Web Extension:
130	```
131	SafariWebExtension/
132	├── SafariWebExtensionHandler.swift # Native message handler
133	└── Resources/
