SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you quickly diagnose and resolve dbt errors and failing tests without guessing, by working from the full error outward to upstream causes and validating the fix end-to-end.

Core Features & Use Cases

  • Systematic error-driven troubleshooting: Read the COMPLETE error, classify it (compilation, database, or dependency/test issues), and identify the likely root cause.
  • Upstream-first investigation: Verify referenced models and sources so you don’t “fix” the wrong file when upstream columns or logic changed.
  • Validation that proves correctness: Enforce rebuilding with dbt build (not just compile), then verify output data and run relevant tests, including downstream impact.

Quick Start

Run the Skill when your dbt model is failing, and ask it to debug the issue by reading the full error, checking upstream models, applying the most likely fix, then rebuilding with dbt build and verifying the resulting data.

FAQPage Schema
How do I debug failing dbt models when compilation or test errors occur?

Debug failing dbt models by reading the complete error message, classifying it as compilation, database, or test failure, then inspecting compiled SQL and upstream models to pinpoint the root cause before applying fixes.

Why do my dbt models break after upstream changes and how can I trace the root cause?

dbt models break after upstream changes when referenced columns or logic shift; trace the root cause by verifying upstream models and sources, inspecting compiled SQL, and confirming the actual data output before fixing the correct file.

What's the best way to verify a dbt fix after correcting a failing model?

Verify a dbt fix by running dbt build to rebuild the model, not just compiling, then validating output data with dbt show and running dbt test to confirm correctness including downstream rebuilds.

How do I resolve dbt test failures without modifying the wrong file?

Resolve dbt test failures by reading the full error, investigating upstream models and sources first, inspecting compiled SQL and actual data, then applying corrections to the correct file and rebuilding with dbt build.

When should I inspect compiled SQL during dbt error troubleshooting?

Inspect compiled SQL during dbt error troubleshooting when a model fails or produces unexpected output, as it reveals how dbt translated macros and references, helping identify mismatches between upstream models and downstream dependencies.

Can debugging dbt errors help when downstream models break after project changes?

Debugging dbt errors systematically resolves downstream model breaks by tracing failures back to upstream root causes, fixing the correct source file, and validating end-to-end correctness through dbt build and dbt test with downstream rebuilds.
