## Why linear_addIssueToProject is rated Medium

This tool creates or modifies a relationship between an existing issue and a project—a reversible write operation. It does not execute code, delete data, or move money. The blast radius is medium because misuse could clutter projects or associate issues with incorrect projects, but the action is reversible (the issue can be removed from the project).

From the tool's own definition: "Tool name 'addIssueToProject' and description 'Add an existing issue to a project' indicate modification of a project's state by adding an issue relationship."

## Use case

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