## Why create_issue_label is rated Medium

This tool creates a new label, which is a reversible write operation. It adds metadata to a Linear workspace without deleting or modifying existing data. The severity is medium because creating labels has limited scope (organizational metadata) but could be misused to spam labels or confuse issue organization. It is not critical because labels don't contain sensitive data and can be deleted.

From the tool's own definition: "Tool name is 'create_issue_label' and description states 'Create a new Linear issue label', indicating a create/write operation that adds a new label resource to a Linear workspace."

## Use case

AI agents use create_issue_label 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)
