## Why add_comment is rated Medium

Adding a comment modifies an issue by appending new data, which is a Write operation. The comment can be edited or deleted afterward, making it reversible rather than destructive. The blast radius is low—an erroneous comment is easily corrected and causes minimal disruption to workflow or data integrity.

From the tool's own definition: "Tool description states 'Add a comment to an issue' - this creates new content (a comment) that is reversible through standard delete/edit operations."

## Use case

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

## Recommended policy (PolicyLayer)
