WHAT IT DOES

What crow_share does on Crow

AI agents use crow_share 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 crow_share is rated Medium

This tool shares data with external contacts over an encrypted P2P channel. It creates/transmits data to another party, which is a Write/Send operation. It includes a confirmation token mechanism suggesting reversibility before execution. The blast radius is medium — data is sent externally but not financial or destructive in nature. Confidence is slightly reduced because the description is truncated.

From the tool's definition Share a memory, research project, source, or note with a connected contact. The data is encrypted end-to-end. Returns a preview and confirmation token on first call; pass the token back to execute.

RECOMMENDED RULE

The rule that runs crow_share safely

crow_share Rate-limited

crow_share 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.
