This feature provides AI assistants with semantic search capabilities for PostgreSQL, TimescaleDB, and Tiger Cloud documentation, as well as prompts/guides for various Tiger Cloud features.
 
 The proxied documentation server ([pg-aiguide](https://github.com/timescale/pg-aiguide)) currently provides the following tools:
-- `view_skill` - Retrieve comprehensive guides for TimescaleDB features and best practices
-- `semantic_search_postgres_docs` - Search PostgreSQL documentation using natural language queries
-- `semantic_search_tiger_docs` - Search Tiger Cloud and TimescaleDB documentation using natural language queries
