 MyDBA is an AI-powered VSCode extension that brings database management, monitoring, and optimization directly into your development environment. Built for developers and database administrators who want intelligent insights without leaving their IDE.
 
 ## 🚀 Features
 
-### Phase 1 MVP ✅ (Complete)
 - **Multi-Database Support**: MySQL 8.0+, MariaDB 10.6+ (GA versions only)
 - **AI-Powered Query Analysis**: Multi-provider support (VSCode LM, OpenAI, Anthropic, Ollama)
 - **Visual EXPLAIN Plans**: Interactive tree diagrams with pain point highlighting
 - **Query Profiling**: Performance Schema integration with waterfall charts
 - **Database Explorer**: Tree view with databases, tables, indexes, and processes
-- **Enhanced Process List**: Transaction detection with grouping by user/host/query
+- **Enhanced Process List**: Transaction detection with grouping by user/host/query, lock status badges
+- **Query History**: Track executed queries with favorites, search, and replay
 - **Security-First Design**: Credential isolation, production safeguards, query anonymization
 - **Documentation-Grounded AI**: RAG system with MySQL/MariaDB docs to reduce hallucinations
+- **Chat Integration**: `@mydba` commands in VSCode Chat with natural language support
 - **Editor Compatibility**: Works in VSCode, Cursor, Windsurf, and VSCodium
-- **Comprehensive Testing**: Integration tests with Docker, 70%+ code coverage
+- **Testing**: 186 unit tests passing, integration tests with Docker (coverage improving to 70%)

-Use `@mydba` in VSCode Chat for natural language database assistance:
+Use `@mydba` in VSCode Chat for conversational database assistance powered by AI.
+
+### Available Commands
+
+| Command | Description | Example |
+|---------|-------------|---------|
+| `/analyze` | Analyze query for anti-patterns and optimization opportunities | `@mydba /analyze SELECT * FROM users` |
+| `/explain` | Visualize query execution plan with pain point detection | `@mydba /explain SELECT * FROM orders WHERE status = 'active'` |
+| `/profile` | Profile query performance with stage-by-stage breakdown | `@mydba /profile SELECT COUNT(*) FROM large_table` |
+| `/optimize` | Get AI-powered optimization suggestions | `@mydba /optimize SELECT * FROM users JOIN orders` |
+| `/schema` | Explore table schema and relationships | `@mydba /schema users` |
+
+### Natural Language Queries
+
+Ask questions in plain English:
 
 ```
-@mydba /analyze SELECT * FROM users WHERE email = 'test@example.com'
-@mydba /explain SELECT * FROM orders WHERE created_at > '2024-01-01'
-@mydba /profile SELECT COUNT(*) FROM large_table
 @mydba how do I optimize this slow query?
 @mydba what indexes should I add to the users table?
+@mydba why is my query doing a full table scan?
+@mydba explain the difference between INNER JOIN and LEFT JOIN
+@mydba show me the current connections
 ```
 
+### Requirements
+
+- VSCode with Chat API support (VSCode 1.90+)
+- Requires an AI provider configured (VSCode LM/OpenAI/Anthropic/Ollama)
+- Enable with `mydba.ai.chatEnabled: true` (enabled by default)
+
+**Note**: Chat participant is not available in all VSCode-compatible editors. Works best in official VSCode with GitHub Copilot.
