Real-time Gmail triage with urgent Slack alerts

Build me an agent workflow that triages my Gmail inbox in real time and pings me on Slack only when something is genuinely urgent.

Trigger: poll Gmail for new emails using the new_email event. Run on every new message that arrives in my inbox.

For each new email, the agent should: 1) Use Gmail Get a Message to fetch the full message and read the subject, snippet, and body. 2) Classify the email on two axes: priority (Urgent, Important, Normal, or Low) and intent (customer issue, sales reply, internal request, newsletter, automated notification, or other). The agent uses judgement here, this is not a deterministic pipeline.

Then apply a custom priority label in Gmail using Modify Message Labels. The labels are Priority/Urgent, Priority/Important, Priority/Normal, and Priority/Low. The first time a label is needed, create it via Gmail Create a Label, then reuse it for every subsequent email. List existing labels first if needed so we do not duplicate.

For anything classified as Urgent, post a concise alert to Slack using Send a Message into the channel #inbox-urgent. The Slack message should contain: sender name and email, a one-line summary of what they want, a suggested next action, and a link to the Gmail thread.

Important: skip the Slack alert for newsletters, calendar invites, and known automated senders (no-reply addresses, marketing domains, system notifications). These should still be labeled in Gmail but never posted to Slack. The Slack channel is for human-judgement urgency only.

Keep the Slack message short and skimmable. I should be able to glance at my phone and decide in five seconds whether to open the email now or later.
