WHY IT NEEDS A POLICY

Why linear_createIssue needs a policy

Creating a new issue is a reversible write operation that modifies Linear's project management state by adding data. It does not execute arbitrary code, delete data, or move money. The severity is medium because a compromised agent could spam issues or create misleading project entries, impacting team workflow and trust, but the operation itself is recoverable by deletion.

From the tool's definition Tool name 'linear_createIssue' and description 'Create a new issue in Linear' indicate data creation. The server description confirms it supports 'issue creation and management' through Linear's GraphQL API.
