A three-day agent replaced a startup's manual triage chore
A consultant built an agent in about three days for a growing startup. It reads incoming items, classifies them, extracts the key details, takes the routine action and logs it. By the client's estimate it cuts about 4.5 hours of weekly work to 0.5 hours of checking, with a person kept for odd cases.

Why it matters
Small, repetitive tasks eat more of the week than anyone likes to admit. Cases like this show an agent taking a chore off someone's plate end to end, not just suggesting what to do. It is one of 201 sightings filed under Productivity on Agent Sightings (number 29 by interest), and one of 183 involving Custom agent.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into your own agent or any similar agent and adjust the details to your situation.
Take this repetitive six-step process: read what comes in, classify it, extract the details, decide the next action, do it in the system, record it. Build an agent for the routine cases and flag anything unusual to me for a check.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
