WHAT IT DOES

What karea_link_jira does on Karea

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

WHY IT NEEDS A POLICY

Why karea_link_jira needs a policy

Linking tasks is a reversible modification operation (the link can typically be removed). It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely retrieve information (Read). While it creates a relationship that connects systems, the primary action is adding/modifying data in the task management system, placing it squarely in the Write category.

From the tool's definition Tool description states 'Link a Karea task to a JIRA issue' — this creates a new link relationship between two systems, modifying the state of the Karea task by adding metadata/associations.
