How to use the ephemeris.generate_tool_list_from_ga_workflow_files function in ephemeris

def load_shed_repos(runnable):
    if runnable.type.name != "galaxy_workflow":
        return []

    path = runnable.path
    if path.endswith(".ga"):
        generate_tool_list_from_ga_workflow_files.generate_tool_list_from_workflow([path], "Tools from workflows", "tools.yml")
        with open("tools.yml", "r") as f:
            tools = yaml.safe_load(f)["tools"]

    else:
        # It'd be better to just infer this from the tool shed ID somehow than
        # require explicit annotation like this... I think?
        with open(path, "r") as f:
            workflow = yaml.safe_load(f)

        tools = workflow.get("tools", [])

    return tools
