WHY IT NEEDS A POLICY

Why linkedin_assets_upload needs a policy

Uploading media assets creates new data in LinkedIn and modifies the user's content library. This is reversible (assets can be deleted) and has no financial or destructive implications. However, it has medium severity because an AI agent could upload inappropriate, misleading, or confidential content that damages the user's professional reputation or violates LinkedIn's terms of service.

From the tool's definition Tool name 'upload' and description 'Upload media assets (images/videos)' indicate creation/modification of data on LinkedIn. This is a write operation that creates new media assets in the user's LinkedIn account.
