WHY IT NEEDS A POLICY

Why update_stream_settings needs a policy

This tool modifies stream configuration (title, description, privacy settings) but does not delete, destroy, execute arbitrary code, or move financial assets. The changes are reversible—settings can be updated again to different values. This places it squarely in the Write category.

From the tool's definition Tool description states it 'Update settings for the current stream such as title, description, or privacy settings' — the verb 'Update' combined with modifiable stream metadata (title, description, privacy) clearly indicates reversible modifications to data.
