What queue_post does on LinkedIn Poster

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

WHY IT NEEDS A POLICY

Why queue_post needs a policy

This tool creates and stores new content (a LinkedIn post) in a queue for future publication. This is a reversible Write operation—the queued post can be edited or deleted before publication. While it doesn't immediately publish (that appears to be the role of 'publish_post'), queuing is fundamentally a data creation/modification action.

From the tool's definition The tool 'queue_post' is described as queuing a LinkedIn post for later publishing. It creates a post entity in a queue system that will be published to the user's LinkedIn profile, modifying their social media presence by creating new content.
