## Why gluecron_label_issue is rated Medium

This tool modifies issue metadata by attaching labels and potentially creating new labels in the repository. This is a write operation that changes repository state reversibly (labels can be removed or modified later). It does not delete data, execute arbitrary code, or move money, so it is Write rather than a more severe category.

From the tool's own definition: "Attach one or more labels to an issue. Labels are created if they don't yet exist on the repo."

## Use case

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

## Recommended policy (PolicyLayer)
