Released 2026-06-01. Two ways to put AI agents in control of your automations: firing workflows, and knowing when to use each tool.
Agent trigger type
- Workflows have a new Agent trigger type in the workflow builder, alongside Schedule, Webhook, API, Form, Playground, and Workflow.
- An Agent trigger has no settings — you just define its input fields. Those inputs become the arguments the agent passes when it calls the workflow.
- In the agent editor, open Workflows the agent can trigger, pick the workflow, then choose its Agent trigger. Only Agent-type triggers are listed — other trigger types can't be fired by an agent.
- At run time the agent decides whether to call the workflow based on your "when should the agent trigger it?" description, and supplies the inputs you defined. The run shows up in your run history with an Agent trigger badge.
- Agent-triggered workflows are included on the Starter, Pro, and Business plans (monthly and annual). On the Free and Student tiers the Agent trigger type appears but is disabled with an upgrade note.
"When should the agent use this?" guidance
- In an agent's Allowed tools panel, every selected platform-tool action and AI model now has an optional "When should the agent use this?" note.
- The note is passed to the agent in its tool list, so it picks the right tool at the right moment instead of guessing — the same guidance workflow triggers already carry ("When to use: …").
- Everything is optional. Leave it blank and nothing changes; existing agents behave exactly as before.
