  "jsonrpc": "2.0",

## Why update_project is rated Medium

This tool modifies an existing project rather than creating or deleting it. The change is reversible since updates can be undone through subsequent modifications. The severity is medium because unintended project updates could disrupt team workflows, visibility, or project settings, but the changes themselves are not irreversible.

From the tool's own definition: "Tool name is 'update_project' and description states 'Update an existing Linear project' - both indicate modification of existing data (project configuration, settings, metadata, etc.)."

## Use case

AI agents use update_project 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.

## Recommended policy (PolicyLayer)
