WHAT IT DOES

What add_bullet_list does on Docx

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

WHY IT NEEDS A POLICY

Why add_bullet_list needs a policy

The tool creates or modifies document content in a reversible manner. It does not delete data (not Destructive), execute arbitrary code (not Execute), involve financial transactions (not Financial), or retrieve data without side effects (not Read). This is clearly a Write operation with low severity since document modifications are easily undone and have minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'add_bullet_list' and description 'Add a bulleted list' indicate the tool modifies a document by inserting formatted content.
