# CmdForge Collections

> **Document Status (January 2026)**: Collections are fully implemented:
> - ✅ API endpoints (`/api/v1/collections`, `/api/v1/admin/collections`)
> - ✅ Web UI pages (`/collections`, `/collections/:name`)
> - ✅ Admin management UI (`/dashboard/admin/collections`)
> - ✅ Database schema
> - ✅ CLI commands (`cmdforge collections list/info/install`)
> - ❌ Registry repo sync - Not implemented (collections managed via admin UI)

Collections are curated groups of tools that can be installed together with a single command.

## Use Cases

1. **Thematic bundles**: "writing-toolkit" with grammar, tone, simplify tools
2. **Application stacks**: "data-science" with json-extract, csv-insights, etc.
3. **Source bundles**: "fabric-text" with all Fabric text processing patterns
4. **Workflow packages**: Tools that work well together for a specific task

## CLI Usage

```bash
# List available collections
cmdforge collections list

# List in JSON format
cmdforge collections list --json

# View collection details
cmdforge collections info writing-toolkit

# View details in JSON format
cmdforge collections info writing-toolkit --json

# Install all tools in a collection
cmdforge collections install writing-toolkit

# Install with pinned versions from collection
cmdforge collections install writing-toolkit --pinned
```

### Example Output

$ cmdforge collections list
