## Why addImprovementActivity is rated Medium

This tool creates or modifies data in a reversible manner—adding comments or activity entries to improvements is a write operation. The blast radius is medium because malicious additions could clutter records, mislead teams about improvement status, or create false activity trails, but the operation is fully reversible (entries can be deleted or corrected).

From the tool's own definition: "Tool name 'addImprovementActivity' and description 'Add a comment or activity entry to an improvement' indicate creation of new data entries (comments/activities) in a structured system."

## Use case

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