## 🔧 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.
