How do you catch broken data models before the dashboards are wrong?

A model triage AI Employee that checks your transformation builds every hour: when a model fails, it reads the error, traces the cause, drafts a fix as a pull request, and alerts the team. Alert plus draft PR: a named human reviews and merges; it never merges on its own.

Problem

A dashboard rarely breaks by showing an error. It breaks by showing a number, a wrong number, because a transformation model upstream failed or silently changed its output, and nobody noticed until someone asked why revenue dropped. A renamed source column, a type that stopped casting, a test that started failing: the build breaks, the model goes stale or wrong, and everything downstream keeps rendering as if nothing happened. This is a narrower problem than general warehouse or pipeline health. The pipeline can be running fine and the warehouse fully up while a single transformation model is quietly producing garbage. Catching it means watching the model builds themselves, reading the actual failure, and knowing which model it is and which downstream dashboards it feeds. And the fix usually isn't a mystery; it's a small, mechanical change that someone has to notice, diagnose, and write before the wrong numbers spread.

What it does

Each hour the model triage AI Employee checks your transformation build results. When a model fails, it reads the error and the model's definition from Git, traces the likely cause, and opens a draft pull request with a proposed fix, then posts an alert naming the failed model and the dashboards it feeds. A named human reviews and merges; it never merges on its own.

How it works

See exactly how the work gets done.

Runs hourly against build results

A scheduled run fires every hour and reads the latest transformation build results, so a failed model is caught within the hour instead of when someone spots a wrong dashboard.

Triages to a root cause

For a failed model it reads the build error and the model's SQL from Git, and traces the failure to a cause, whether a renamed source column, a broken reference, or a failing test, rather than just reporting that something is red.

Reads Git and the warehouse, with permissions you set

It reads model definitions from the repository and build metadata from the warehouse with roles you scope. Credentials stay in memory, injected at run time, never exposed to the model.

Drafts a fix as a pull request

It writes the proposed change onto a new branch and opens a draft PR against your repo, with the diff, the failed model, and its reasoning in the description. It has no permission to push to your default branch or merge.

Alerts with the blast radius

It posts one alert per failure naming the model, the proposed PR, and the downstream dashboards that model feeds, so the team knows what's at risk before anyone opens them.

A named human merges

The draft PR waits for a reviewer. A named engineer reads the diff, approves or edits, and merges. Nothing reaches your models without that signature.

Guardrails

Runs in your environment

Every run is isolated inside your own infrastructure, reaching only the warehouse, the repository, and the channel it posts to. Your data and code never leave.

Never merges

It can open a draft pull request on a new branch and nothing more. It has no permission to push to your default branch or merge its own change.

A named human signs off

Every proposed fix waits for a named reviewer to read the diff and merge. The irreversible step is always a person's signature, never the AI Employee's.

Permissions you set

The Git and warehouse credentials are scoped roles that stay in memory, injected at run time, never exposed to the model or written to logs.

You own the rules

Which models it watches, how it triages, and what a fix may touch are yours, versioned and changed on your terms, not in a vendor dashboard.

The outcome

The broken model that used to surface as a wrong dashboard days later now surfaces within the hour, triaged to a cause with a fix already drafted and the blast radius named. The AI Employee catches it and proposes the fix; a named engineer reviews and merges.
