WHAT IT DOES

What filters.createFilter does on Gojira

AI agents use filters.createFilter 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 filters.createFilter needs a policy

Creating a filter is a reversible write operation that adds a new configuration artifact to the system. It modifies the organization's saved filters but does not execute queries with external effects, delete data, or perform financial transactions.

From the tool's definition Tool name is 'createFilter' and description explicitly states 'Create a filter', indicating it creates new data structures within Jira/Atlassian (filters for saved searches, dashboards, or reports).
