WHY IT NEEDS A POLICY

Why add_card_tag needs a policy

This is a Write-category tool because it modifies existing data (adds a tag to a card) in a reversible manner. The severity is medium because while the blast radius is limited to card metadata, misuse by an AI agent could spam tags across many cards or add inappropriate tags, causing moderate organizational disruption. The confidence is high due to clear description of the additive/write operation.

From the tool's definition Tool performs 'Add a tag to a card' — creates or modifies a relationship/property on an existing card, with reversible effects (tags can be removed).
