Catch a funnel step that stopped converting, with the numbers either side

Mitra checks your core funnel in Mixpanel every six hours and compares each step's conversion against the same hours over the past two weeks. When a step drops well below its usual rate, Mitra posts the before and after numbers to Slack and opens a Linear issue. A normal reading posts nothing.

The prompt

Every six hours, check the signup funnel in Mixpanel and compare each step's conversion with the same hours over the past two weeks. If a step has dropped well below its usual rate, post the before and after numbers to #product in Slack and open a Linear issue.

What the agent actually does.

Read the funnel
The agent pulls every step of your signup funnel from Mixpanel for the last six hours — how many people entered each step and how many made it through.
Compare with the usual rate
Each step is set against the same hours over the previous two weeks, so a quiet Sunday morning is not mistaken for a broken step.
Decide whether anything is worth saying
Only a step that fell well below its normal range is raised. A run that finds nothing ends quietly, which is what keeps the channel worth reading.
Raise it with the numbers
The Slack message names the step, the rate before, the rate now and how many people dropped out, so the first question anyone asks is already answered.
Open an issue to own it
A Linear issue carries the same numbers and a link back to the funnel, so the alert becomes work with an assignee instead of a message that scrolls away.

Make it yours.

Product managers and engineers on a product where a broken step in the funnel is usually found by a customer. If your alerting says a rate crossed a line but never what the rate was, this is the gap. Change any of this by saying so — there is nothing to rewire.

Read the funnel from PostHog or Amplitude instead of Mixpanel.
Watch checkout and onboarding as two separate funnels in the same run.
Skip the Linear issue overnight and post to Slack only until morning.

Questions, answered.

How do I get an alert that says what changed, not just that something changed?

Ask for the numbers in your instructions and Mitra includes them. The agent reads the step's conversion now and its usual rate over the past two weeks, then posts both with the count of people affected. Mitra compares the two readings and reports the difference; the cause is still your call.

What stops an anomaly agent from becoming noise?

A run that finds nothing posts nothing, so Mitra speaks only when a step sits well outside its recent range. You decide how far outside counts, in one sentence, and can raise the bar after a week of watching. Mitra records every run, including the quiet ones.
