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

Try saying

“use slack to slack …”

In a workflow

As a step in a multi-step workflow DAG:

{
  "id": "s1",
  "agent": "slack",
  "action": "SLACK_ADD_REACTION",
  "args": {
    "channel": "…",
    "timestamp": "…",
    "emoji": "…"
  },
  "depends_on": [],
  "outputs": []
}

Direct call

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

curl -X POST http://127.0.0.1:8000/execute_tool \
  -H "Content-Type: application/json" \
  -d '{"tool_name":"SLACK_ADD_REACTION","args":{"channel":"…","timestamp":"…","emoji":"…"}}'
