Today's events partition wrote 612K rows against a ~1.04M daily baseline, and 3 new columns appeared that your schema doesn't map. Looks like a truncated upstream export.
How an agent works
An agent watches one thing and acts on it. Not a workflow, just a standing watch that usually does nothing and acts the moment it should.
You stay in control
An agent does what you'd do, and only what you've authorized.
The same trusted numbers
It acts on the same governed metrics as your dashboards, and every action is logged and traceable.
You approve anything that writes
It alerts and recommends on its own; anything that changes data is yours to approve.
Try it on a test channel first
Point a new agent at a throwaway channel and watch its judgment before it touches anything real.
No false alarms
It remembers what it already flagged and waits before acting again, so it won't alert you about the same thing twice.
What you can put an agent on
Tie the files in S3 to the tables they feed
It checks the rows and partitions landing in your buckets against the warehouse tables they load and the source systems that produced them, then flags the gaps before your models run. You catch a truncated export or a missed partition while it's still a file in S3, not after it's poisoned every dashboard downstream.
Catch a schema change before it breaks the load
When a new column appears, a type shifts, or a field your pipeline depends on goes missing, it tells you which objects changed and what reads from them downstream. You hear about the drift while you can still adjust the mapping, instead of debugging a failed dbt run at 7am.
Know the moment an expected drop doesn't land
It learns the cadence of each prefix and watches for the file that should have arrived and didn't, or arrived far smaller than usual. You find out a feed is stale before the stale numbers reach anyone who'd act on them.
Run any Python it needs to get the job done
Beyond alerts and write-backs, an agent can run arbitrary Python, so it can do whatever the task actually requires: re-trigger a load, parse a malformed file, reshape a partition, or wire into your own orchestration. The action space is yours to define.
Why not just build it yourself?
You could rig one of these with a cron job and a Slack webhook in an afternoon. The watching is the easy part. Here's what you'd own forever, and don't, here:
- →The cross-source join: not one tool's data, but it reconciled against the rest of your stack
- →A trusted, consistent metric: the same number your dashboards use
- →The investigation into why, when something fires
- →A full audit trail of everything it did
- →The upkeep, when the schema drifts or the script breaks at 2am
The data it works from
Every Amazon S3 object, modeled and query-ready the moment you connect.
It runs on your real buckets (mixed file formats, half-documented prefixes, columns nobody mapped yet), not a tidy demo.
Where it acts
Slack
A message in the channel you choose, with the context and a button to act on it.
A summary in the inbox of the people who need to see it.
Webhook
A payload to your own systems, to wire the agent into whatever you already run.
Warehouse write-back
A flag written back to your warehouse for everything downstream to pick up.
