Databricks Streaming Guardian

The data-ops spine of the pack. Delta Lake, Liquid Clustering, Structured Streaming, and DLT each ship a different set of foot-guns that fire most visibly when production data flows through them at scale — and most of them are documented platform decisions that surprise engineers, not bugs. This skill's job is friction at trigger time (a hook that blocks the genuinely-irreversible op) plus deterministic recovery when something already broke.

Overview

Twelve foot-guns, grouped by the surface that triggers them. Eleven are owned outright (D01–D10, D12); the twelfth — D11, DLT rebuild cost — is shared with databricks-cost-leak-hunter: this skill checks the rebuild cost as part of pre-refresh safety, that skill owns ongoing cost optimization.
