The revenue column in your Ops KPI spreadsheet shows $218k for last week, but Stripe plus QuickBooks shows $244k for the same period. The gap opened three weeks ago when someone hardcoded a filter. 4 other sheets reference this number downstream.
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 your spreadsheet KPIs back to the source systems
It joins the numbers in your Google Sheets to the systems they were pulled from, and flags when a sheet has drifted from the source of truth. You find out before someone builds a deck on a stale export, not after the board meeting.
Catch the sheet that stopped getting updated
When a manually maintained spreadsheet goes quiet, it tells you which one, how long it has been stale, and what downstream reports depend on it. You hear about it while there is still time to refresh, not when someone asks why last month's numbers are in this month's report.
Flag when someone renames or reshuffles the columns
When a column header changes, a new tab appears, or rows shift in a way that breaks the expected structure, it surfaces exactly what moved and what queries or dashboards downstream would break. You catch the structural change before your pipeline does.
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: call an API, kick off a job, reshape the data, or wire into your own tooling. 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 Google Sheets object, modeled and query-ready the moment you connect.
It runs on your real Google Sheets (the merged cells, the inconsistent headers, the blank rows someone left in, the tabs named 'Sheet2 (old copy)'), 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.
Hand off to Fi
Kick the question to Fi to investigate the why and propose the fix.
MCP
Expose it to your own agents and tools over MCP, and drive it from your stack.
Run it in your own VPC or fully self-hosted. Everything it does is pure SQL and Python you can inspect.
