What send_openclaw_message does on Nodebench

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

RISK

Why send_openclaw_message is rated Medium

This tool creates and transmits messages, which is a write operation with side effects (messages are sent and received by others). While not destructive or financial, it could be misused to send spam, impersonate users, or manipulate communications across multiple channels.

From the tool's definition Tool description states 'Send a message through any connected channel' - this is a write operation that creates/sends messages. The 'connected channel' suggests broad applicability across multiple communication systems.

send_openclaw_message Rate-limited

send_openclaw_message 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.
