WHY IT NEEDS A POLICY

Why create_label needs a policy

Creating a label is a write operation that adds new metadata to a project. It is reversible (labels can be deleted or modified) and has minimal blast radius—miscreating labels does not corrupt data, delete information, or trigger external operations. This is clearly a Write-category tool with low severity.

From the tool's definition Tool name 'create_label' and description 'Create a new label in a project' indicate data creation. Labels are metadata that can be created and modified reversibly without irreversible consequences.

Verdict

create_label Rate-limited

create_label stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
