## Why linear_createIssueRelation is rated Medium

This tool creates relationships between issues (blocks, is blocked by, etc.), which modifies data in the Linear issue tracking system but does not delete, execute commands, or move financial resources. The action is reversible—relationships can be removed.

From the tool's own definition: "Tool name includes 'create' and description states 'Create relations between issues', indicating reversible creation of metadata linking issues together."

## Use case

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

## Recommended policy (PolicyLayer)
