send_to_agent plugin
Critical infrastructure. This plugin provides the send_to_agent tool — the only way agents can send messages to each other through the relay.
What it does
Registers a single tool (send_to_agent) with Hermes' tool registry. The tool POSTs messages to the relay on www0, which routes them to the target agent's webhook.
Why it matters
Without this plugin, agents cannot communicate with each other. Inter-agent coordination, delegation, and status reporting all depend on it.
Do not remove this plugin. It was accidentally deleted once (2026-05-09) and broke all inter-agent messaging until restored.
