WHY IT NEEDS A POLICY

Why create_quote_card needs a policy

This tool creates a new digital asset (a quote card) without executing arbitrary code, accessing sensitive data, deleting content, or moving money. The output is a static visual/text composition. While it modifies state by adding a new card, the operation is fully reversible and low-risk. Severity is low because misuse would only result in unwanted quote cards, with minimal blast radius.

From the tool's definition Tool description states 'Generate a quote card' — this creates new content (a quote card asset) that is stored or transmitted. The term 'generate' combined with 'create' indicates a write operation that produces a new artifact.
