# External Library Registry

## Purpose

This file lists external libraries/frameworks that should use **ExternalScout** (via Context7) for live documentation instead of relying on potentially outdated training data.

## When to Use This

**ContextScout** checks this list when:
1. User asks about a library/framework
2. No internal context exists in `.opencode/context/development/frameworks/`
3. Query matches a library name below

**Action**: Recommend **ExternalScout** subagent

## Detection Patterns

ContextScout and ExternalScout should match queries containing:
- Library name (case-insensitive)
- Common variations (e.g., "next.js" vs "nextjs")
- Package names (e.g., "@tanstack/react-query")

**Examples**:
- "How do I use **Drizzle** with PostgreSQL?" → Match: Drizzle ORM
- "Show me **Next.js** App Router setup" → Match: Next.js
- "**TanStack Query** with Server Components" → Match: TanStack Query
- "**Better Auth** integration" → Match: Better Auth

## Adding New Libraries

To add a new library:
1. Add entry under appropriate category
2. Include: Name, aliases, docs link, Context7 command, common topics
3. (Optional) Add query optimization patterns
4. Update ExternalScout if needed (usually automatic)

**Template**:
```markdown
#### Library Name
- **Aliases**: `alias1`, `alias2`, `package-name`
- **Docs**: https://example.com/docs
- **Context7**: `use context7 for library-name`
- **Common topics**: topic1, topic2, topic3
```

## Usage by ExternalScout

ExternalScout uses this file to:
1. **Detect** which library the user is asking about
2. **Load** query optimization patterns for that library
3. **Build** optimized Context7 queries
4. **Fetch** live documentation
5. **Return** filtered, relevant results
