 ## Meta Tools (Beta)
 
-Meta tools enable dynamic tool discovery and execution without hardcoding tool names. The search functionality uses **hybrid BM25 + TF-IDF search** for improved accuracy (10.8% improvement over BM25 alone).

-### Hybrid Search Configuration
-
-The hybrid search combines BM25 and TF-IDF algorithms. You can customize the weighting:
-
-```python
-# Default: hybrid_alpha=0.2 (more weight to BM25, proven optimal in testing)
-meta_tools = tools.meta_tools()
-
-# Custom alpha: 0.5 = equal weight to both algorithms
-meta_tools = tools.meta_tools(hybrid_alpha=0.5)
-
-# More BM25: higher alpha (0.8 = 80% BM25, 20% TF-IDF)
-meta_tools = tools.meta_tools(hybrid_alpha=0.8)
-
-# More TF-IDF: lower alpha (0.2 = 20% BM25, 80% TF-IDF)
-meta_tools = tools.meta_tools(hybrid_alpha=0.2)
-```
-
-**How it works:**
-- **BM25**: Excellent at keyword matching and term frequency
-- **TF-IDF**: Better at understanding semantic relationships
-- **Hybrid**: Combines strengths of both for superior accuracy
-- **Default alpha=0.2**: Optimized through validation testing for best tool discovery
