+
+          Prerequisite: The Looker session must be in Development Mode. Use `dev_mode: true` first.
+
+          Parameters:
+          - project_id (required): The unique ID of the LookML project.
+          - file_id (optional): The ID of the file to filter tests by. This must be the complete file path from the project root (e.g., `models/my_model.model.lkml` or `views/my_view.view.lkml`).

+
+          Prerequisite: The Looker session must be in Development Mode. Use `dev_mode: true` first.

+          - test (optional): The name of the test to run.
+          - model (optional): The name of the model to run tests for.
+
+          Output:
+          A JSON array containing the results of the executed tests, where each object includes:
+          - model_name: Name of the model tested.
+          - test_name: Name of the test.
+          - assertions_count: Total number of assertions in the test.

+        description: |
+          This tool generates boilerplate LookML views directly from the database schema.
+          It does not create model or explore files, only view files in the specified folder.
+
+          Prerequisite: The Looker session must be in Development Mode. Use `dev_mode: true` first.
+
+          Parameters:
+          - project_id (required): The unique ID of the LookML project.
+          - connection (required): The database connection name.
+          - tables (required): A list of objects to generate views for. Each object must contain `schema` and `table_name` (note: table names are case-sensitive). Optional fields include `primary_key`, `base_view`, and `columns` (array of objects with `column_name`).
+          - folder_name (optional): The folder to place the view files in (defaults to 'views/').
+
+          Output:
+          A confirmation message upon successful view generation, or an error message if the operation fails.
