## New Features

### ExternalScout Subagent (v2.0.0)
- Fetches live, version-specific documentation for external libraries via Context7 API
- Supports 18+ libraries: Drizzle, Better Auth, Next.js, TanStack, Cloudflare Workers, AWS Lambda, Vercel, Shadcn/ui, Radix UI, Tailwind CSS, Zustand, Jotai, Zod, React Hook Form, Vitest, Playwright
- Lazy-loads query patterns for specific libraries only
- Filters and formats results by relevance (Critical → High → Medium)
- Fallback to official docs via webfetch
- 42% token reduction via research-backed optimization
- Added to registry with skill:context7 dependency

### Context7 Skill

- Added 3-tier execution priority system
- 20% token reduction via visual operators (→, |, @refs)
- Simplified XML structure (4% XML) for multi-model compatibility (Claude, Gemini, GPT-4)
- Added external library detection and ExternalScout recommendation
- Added dependency: subagent:externalscout
- 100% behavior preservation

Context7 Skill

Purpose

Fetches live, version-specific documentation for external libraries and frameworks using the Context7 API. Ensures you always get current API patterns instead of potentially outdated training data.

Golden Rule: Always fetch live docs for external libraries—training data may be outdated.

Quick Start

The ExternalScout subagent is the recommended way to fetch external documentation. It handles:

  • Library detection
  • Query optimization
  • Documentation filtering and sorting
  • Formatted results with code examples

Invocation:

Use ExternalScout to fetch documentation for [Library Name]: [your specific question]

Example:

Use ExternalScout to fetch documentation for Drizzle ORM: How do I set up modular schemas with PostgreSQL?

Alternative: Direct Skill Usage

You can also invoke the Context7 skill directly via bash:

# Step 1: Search for library
curl -s "https://context7.com/api/v2/libs/search?libraryName=LIBRARY&query=TOPIC" | jq '.results[0]'

# Step 2: Fetch documentation
curl -s "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=OPTIMIZED_QUERY&type=txt"

See SKILLS.MD for detailed API documentation.

Supported Libraries

See library-registry.md for the complete list of supported libraries including:

  • Database & ORM: Drizzle, Prisma
  • Authentication: Better Auth, NextAuth.js, Clerk
  • Frontend: Next.js, React, TanStack Query/Router/Start
  • Infrastructure: Cloudflare Workers, AWS Lambda, Vercel
  • UI: Shadcn/ui, Radix UI, Tailwind CSS
  • State: Zustand, Jotai
  • Validation: Zod, React Hook Form
  • Testing: Vitest, Playwright

Adding New Libraries

To add a new library to the registry:

  1. Edit library-registry.md
  2. Add entry under appropriate category:
    #### Library Name
    - **Aliases**: `alias1`, `alias2`, `package-name`
    - **Docs**: https://example.com/docs
    - **Context7**: `use context7 for library-name`
    - **Common topics**: topic1, topic2, topic3
    
  3. (Optional) Add query optimization patterns
  4. ExternalScout will automatically detect the new library

  • ContextScout: .opencode/agent/subagents/core/contextscout.md
