Slack

Slack tools send messages to the team's Slack channel via a configured webhook. These are useful for notifications and for agents to escalate questions to humans when confidence is low.

send_slack_message

Send a notification to the team's Slack channel.

Parameters

Parameter	Type	Required	Description
text	string	Yes	Message text (supports Slack markdown: *bold*, _italic_, `code`, >quote)

Example

{
  "name": "send_slack_message",
  "arguments": {
    "text": "New coverage published: *How Catena Labs is Reinventing PR* in TechCrunch. Sentiment: positive."
  }
}

ask_slack

Post a question to Slack when the agent needs human input. Use this when confidence is low about a decision -- for example, when it is unclear if an email represents a new opportunity, when a contact-outlet association is ambiguous, or when the next action is uncertain.

Parameters

Parameter	Type	Required	Description
question	string	Yes	The question for the team
context	string	No	Background context to help the team answer
options	string[]	No	Suggested options if applicable

Example

{
  "name": "ask_slack",
  "arguments": {
    "question": "Should this email from Sarah Chen about the AI conference be tracked as a new opportunity?",
    "context": "Sarah mentioned a panel spot at TechWorld 2026. We already have a TechWorld speaking opportunity in the pipeline but it's for a keynote, not a panel.",
    "options": [
      "Create a new opportunity for the panel",
      "Add to the existing TechWorld keynote opportunity",
      "Ignore -- not a good fit"
    ]
  }
}
