                 "TRELLO_TOKEN": "your_trello_token",
                 "LOG_PATH": "/path/to/log.txt",
                 "ENABLE_OBSIDIAN_TOOLS": "True/False",

                 "EMBEDDINGS_PATH": "/path/to/embeddings.json"
         }
      }
   }
}

Replace the paths and credentials with your actual values:

• ENABLE_CALENDAR_TOOLS: Set to True to enable Google Calendar tools
• ENABLE_NEWS_SEARCH: Set to True to enable Google News search
• ENABLE_WEB_PARSER: Set to True to enable the web parser tool

To enable semantic search capabilities, you'll need to install the Vector Search plugin for Obsidian.

After the reindexing process is complete, the plugin will generate a JSON file containing vector embeddings at the following location:
