Understand Downstream Impact Before Changing a dbt Model

Understand downstream impact before changing a model.

Analyze the blast radius of dbt model changes using dependency information and column-level lineage.

The problem it solves

A small dbt change can affect downstream marts, dashboards, and business processes. Teams need to know what depends on a model or column before merging changes.

What it does

Identifies downstream models and consumers.
Uses dbt graph context and column-level lineage.
Summarizes affected columns and risky dependencies.
Helps reviewers understand blast radius before merge.

When to use it

BEFORE

changing a shared staging or intermediate model

WHEN

renaming or removing columns

DURING

dbt refactors

WHEN

assessing change risk in a pull request

How it works

The skill locates the changed model, maps the dbt dependency graph, traces lineage, and reports downstream impact.
