WHY IT NEEDS A POLICY

Why coda_create_doc needs a policy

This tool creates new documents in Coda, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or perform reads. The severity is medium because creating documents could consume workspace resources or be used to generate unwanted content at scale, but the impact is reversible (documents can be deleted).

From the tool's definition Tool name 'coda_create_doc' and description 'Create a new Coda document' indicate creation of new data. The optional 'source_doc' parameter allows duplicating an existing document as a template, extending the scope to include copying operations.
