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.
