BEFORE (Narrow Descriptions):

- Only advertised "documentation" queries
- Missed: conceptual, comparison, troubleshooting, best practices, use case, etc.
AFTER (Comprehensive Descriptions):
docs_ask: "Answer ANY knowledge-based question about Hedera Network..."
- Explicitly lists: conceptual, how-to, comparison, troubleshooting,
best practices, use case, architecture, migration, security
- Auto-detects query intent for optimized responses
- Supports expertise levels (beginner, intermediate, advanced)
IMPACT:
✅ Conceptual questions now explicitly supported
✅ Comparison questions (Hedera vs X) now routed correctly
✅ Troubleshooting questions recognized
✅ Best practices queries handled
✅ Use case suitability questions addressed
✅ Architecture/system design questions supported
✅ Migration guidance available
✅ Security concerns properly addressed
✅ Intent-based answer optimization
✅ Expertise level customization

✨ RAG Tool Refactoring Complete!
The RAG tools now properly catch ALL types of Hedera questions:
- Tool descriptions are comprehensive and explicit
- Intent classification auto-detects question types
- Query expansion improves search relevance
- Expertise levels allow customized responses
- All 10 question intent types are supported
The RAG system will no longer miss questions like:
- "What is Hedera?" (was too conceptual)
- "Hedera vs Ethereum?" (was comparison)
- "Why did my tx fail?" (was troubleshooting)
- "Best practices for DeFi?" (was best practices)
Total indexed materials remain fully searchable (8,843 chunks).
