AI agents use storybloq_note_update to create or update resources in Storybloq — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Storybloq environment.
This tool modifies existing notes within the storybloq context management system. Updates are reversible (prior versions can be restored or notes re-edited), so it falls under Write rather than Destructive. The severity is medium because unintended note modifications could lose context important to ongoing projects, but the effect is contained within project metadata rather than production systems.
From the tool's definition Tool name 'storybloq_note_update' and description 'Update an existing note' indicate modification of stored data. The verb 'update' is characteristic of reversible write operations.
