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that should use ExternalScout (via Context7) for live documentation instead of relying on potentially outdated training data.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:

#### 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
