What customfields.setCustomFieldOptions does on Gojira

AI agents use customfields.setCustomFieldOptions to create or update resources in Gojira — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gojira environment.

WHY IT NEEDS A POLICY

Why customfields.setCustomFieldOptions needs a policy

This tool creates or modifies data (custom field options in Jira) in a reversible manner. It does not delete options permanently (Destructive), execute arbitrary code (Execute), or move money (Financial). However, the severity is high because misconfiguration could break workflows, affect all issues using this field, and impact team productivity across an organization-wide Jira instance.

From the tool's definition Tool description states 'Replace the option set on a custom field context' — this modifies custom field configuration. The verb 'Replace' indicates overwriting existing options, which is a reversible write operation.
