Updating reusable custom functions across playbooks

A computing device, comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to perform operations including:
• causing display of a graphical user interface including a playbook editor of an information technology (IT) and security operations application, the playbook editor allowing a user to modify an initial user-provided code that defines a custom function for use in responding to a security or operational issue in an IT environment;
• receiving, by the IT and security operations application, input modifying the initial user-provided code associated with the custom function to obtain modified user-provided code, wherein a custom function block representing the custom function is included in each of a first playbook and a second playbook, and wherein each of the first playbook and the second playbook includes a respective plurality of function blocks implementing operations used to respond to security or operational issues in an IT environment;
• storing the modified user-provided code associated with the custom function in a source code repository;
• executing the first playbook including the custom function block, wherein execution of the first playbook includes obtaining and executing the modified user-provided code from the source code repository;
• and
• executing the second playbook including the custom function block, wherein execution of the second playbook includes obtaining and executing the modified user-provided code from the source code repository.
