System Documentation
What problem does it solve?
It resolves conflicts between notebook outputs and warehouse/SQL results by enforcing a disciplined, evidence-first workflow to locate where the numbers first diverge.
Core Features & Use Cases
- Root-cause-first debugging: Reproduces the mismatch and traces backward through joins, filters, windowing, and unit alignment without applying speculative fixes.
- Phase-based investigation: Guides you through root-cause investigation, pattern analysis using a working reference, minimal hypothesis testing, and one-at-a-time implementation.
- Targeted mismatch scenarios: Covers disagreements in row counts, unique units, experiment metrics, sample ratios, timezones/window boundaries, join cardinality explosions, missing rows, hidden filters, and stale notebook state.
Quick Start
Use ds-systematic-debugging when your notebook and SQL disagree on treatment lift or row counts, and ask the agent to reproduce the mismatch and trace backward to the first transformation where values diverge.
