## 🔧 Implementation Strategy

### Dual-Versioning Approach

To satisfy both **local development needs** (using official versions) and **repository flexibility** (offering both versions), a dual-versioning strategy was implemented:

#### Local Environment (Developer Machine)

```
skills/
├── docx -> docx-official          (symlink)
├── pdf -> pdf-official             (symlink)
├── pptx -> pptx-official          (symlink)
├── xlsx -> xlsx-official           (symlink)
├── brand-guidelines-anthropic/
├── brand-guidelines-community/
├── internal-comms-anthropic/
├── internal-comms-community/
```

**Result**: Local development uses official Anthropic versions by default.

#### GitHub Repository

```
skills/
├── docx-official/                  (official Anthropic)
├── docx-community/                 (community version)
├── pdf-official/                   (official Anthropic)
├── pdf-community/                  (community version)
├── pptx-official/                  (official Anthropic)
├── pptx-community/                 (community version)
├── xlsx-official/                  (official Anthropic)
├── xlsx-community/                 (community version)
├── brand-guidelines-anthropic/
├── brand-guidelines-community/
├── internal-comms-anthropic/
├── internal-comms-community/
```

**Result**: Repository users can choose between official and community versions.
