WHAT IT DOES

What wf_publish_post does on Crow

AI agents use wf_publish_post 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 wf_publish_post is rated Medium

Publishing a post is a reversible write operation—the post can be unpublished, deleted, or edited afterward. It does not permanently destroy data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read).

From the tool's definition Tool description states it will 'Move a draft post into a collection (blog), making it public and federated over ActivityPub.' This creates and publishes content to a public platform, modifying the state of data by transitioning it from draft to published.

RECOMMENDED RULE

The rule that runs wf_publish_post safely

wf_publish_post Rate-limited

wf_publish_post stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
