run_lookml_tests

This skill runs LookML tests in the project, filtered by file, test, and/or model. These filters work in conjunction (logical AND).

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

Parameters:

project_id (required): The unique ID of the project to run LookML tests for.
file_id (optional): The ID of the file to run tests for. This must be the complete file path from the project root (e.g., models/my_model.model.lkml or views/my_view.view.lkml).
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.
assertions_failed: Number of assertions that failed.
success: Boolean indicating if the test passed.
errors: Array of error objects (if any), containing details like message, file_path, line_number, and severity.
warnings: Array of warning messages (if any).

Parameters

Name	Type	Description	Required
project_id	string	The id of the project to run LookML tests for.	Yes
file_id	string	Optional id of the file to run tests for.	No
test	string	Optional name of the test to run.	No
model	string	Optional name of the model to run tests for.	No

switch_git_branch

This skill is used to switch the git branch of a LookML project. This only works in dev mode.

Parameters:

project_id (required): The unique ID of the LookML project.
branch (required): The branch to switch to.
ref (optional): The ref to change a branch with reset --hard on a switch operation.

Parameters

Name	Type	Description	Required	Default
project_id	string	The project_id	Yes
branch	string	The git branch to switch to	Yes
ref	string	The ref to switch the branch to using `reset --hard`.	No	``

update_project_file

This skill modifies the content of an existing LookML file within a specified project.

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.
