WHAT IT DOES

What lemmy_unfollow_community does on Crow

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

RISK

Why lemmy_unfollow_community is rated Medium

Unfollowing/unsubscribing from a community modifies the user's subscription state on Lemmy. This is a reversible action (the user can re-follow the community), so it falls under Write rather than Destructive. The blast radius is low as it only affects the user's own community membership.
