## Why projects_update is rated Medium

This tool creates or modifies data reversibly by updating project attributes. It does not delete data (which would be Destructive) nor execute arbitrary code (which would be Execute). The impact is confined to project metadata changes, making it a Write operation. Severity is medium because unauthorized project modifications could disrupt task management workflows and team coordination, but changes are reversible.

From the tool's own definition: "Tool name 'projects_update' and description 'Update an existing project' indicate modification of existing data without deletion."

## Use case

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