Compare two SQL Server workload captures — a baseline and a current period, a fast day and a slow day, before and after an upgrade or configuration change, or production against test — to find what regressed and why. Applies 14 checks (WC1–WC14) covering capture comparability, per-query regressions and improvements matched by query_hash, new and disappeared heavy queries, systemic versus isolated regression, regression class (CPU-, reads- or wait-driven), execution-volume shifts, sp_configure…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SQL Server Workload Comparison Skill

## Purpose

Explain a difference between two captures of the same workload. Applies 14 checks (WC1–WC14) across four categories:

- **WC1** — Comparability: whether the two captures can be compared at all, and which checks they cannot support
- **WC2–WC10** — Query-level change: per-query regression and improvement matched by `query_hash`, heavy queries that appeared or disappeared, regression spread across the workload, the class of each regression (CPU, reads, or waiting), and execution-volume shifts with flat per-execution cost
- **WC11–WC13** — Configuration change: `sp_configure` `value_in_use`, server properties (version, edition, CPU count, memory), database options, and database-scoped configurations — including settings present on one side only
- **WC14** — Wait profile: a shift in the dominant wait category, compared per second per CPU so different window lengths and core counts do not distort it

How to install

The exact contents, by fingerprint
mdr add vanterx/mssql-performance-skills/sqlworkload-compare@sha256:257205115a91555f

The line at the top of this page pins the label git:20261015.4b8976e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
