AI agents use bear-create-note to create or update resources in Bear Notes — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Bear Notes environment.
This tool creates new notes in the Bear application, which is a reversible write operation. Notes can be deleted or edited afterward. There is no destruction, code execution, financial impact, or irreversible data loss. The blast radius is minimal—at worst, an AI agent could create unwanted notes that the user can delete. This is categorized as Write rather than Destructive.
From the tool's definition Tool description states 'Create a new note' with 'optional title, content, and tags' that 'will be immediately available in Bear app.' This is a create operation that modifies the user's note library.

"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
