How to use it

You normally trigger this by describing what you want in chat — the agent selects SIGNAL_DELETE automatically. For example:

Try saying
“use signal to signal …”

In a workflow

As a step in a multi-step workflow DAG:

json
{
  "id": "s1",
  "agent": "signal",
  "action": "SIGNAL_DELETE",
  "args": {
    "recipient": "…",
    "timestamp": 1
  },
  "depends_on": [],
  "outputs": []
}

Direct call

For scripting, call it directly via POST /execute_tool. Every tool returns { success, message, data }.

bash
curl -X POST http://127.0.0.1:8000/execute_tool \
  -H "Content-Type: application/json" \
  -d '{"tool_name":"SIGNAL_DELETE","args":{"recipient":"…","timestamp":1}}'
