WHAT IT DOES

What create_project_note does on Repsona

AI agents use create_project_note to create or update resources in Repsona — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Repsona environment.

WHY IT NEEDS A POLICY

Why create_project_note needs a policy

This tool creates new data (a project note) which is a Write operation. It does not execute arbitrary code, delete data, move money, or cause irreversible changes. The severity is medium because unauthorized note creation in projects could lead to data pollution, misinformation, or disruption of project workflows, but notes are typically retrievable and modifiable.

From the tool's definition Tool description states '指定したプロジェクト内にノートを作成します' (creates a note within a specified project). The verb 'create' indicates data creation with reversible effects.
