Analyze SQL Server wait statistics to identify why the server or a session is slow. Applies 45 checks (V1–V45) covering I/O, locks, parallelism, memory, CPU, TempDB, log I/O, network, latch contention, log space exhaustion, poison/throttle waits, backup I/O, insert hotspots, cumulative skew detection, multi-snapshot trend analysis, In-Memory OLTP, Columnstore, Query Store, Transaction/DTC, Service Broker, Full Text Search, Parallel Redo, forced memory grants, grant timeouts, stolen memory…
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 Wait Statistics Review Skill ## Purpose Analyze SQL Server wait statistics and identify the dominant bottleneck using the **Waits and Queues** methodology (Microsoft's *Performance Tuning Using Waits and Queues* whitepaper, as developed by Paul Randal of SQLskills and Brent Ozar's First Responder Kit — sources in `references/community-practices.md`). Applies 45 checks (V1–V45): V1–V18 classify each significant wait type into its root cause and produce a prioritized remediation plan; V19–V26 perform multi-snapshot trend analysis when 3+ time windows are provided — detecting worsening trends, spikes, peak periods, and emerging bottlenecks; V27–V29 cover specialized scenarios (PAGELATCH on user databases, backup I/O, cumulative skew from outlier events); V30–V36 cover modern feature wait types (In-Memory OLTP, Columnstore, Query Store, Transaction/DTC, Service Broker, Full Text Search, Parallel Redo); V37–V40 add DMV-level memory and I/O detail — forced memory grants, grant timeouts, stolen memory, and file-level I/O latency (requires optional capture queries); V41–V44 cover SQL 2019/2022 IQP/PSP/ADR feature-specific wait types and TempDB memory-optimized metadata… …

How to install
mdr add vanterx/mssql-performance-skills/sqlwait-review@sha256:f37a445726cbed0fThe line at the top of this page pins the label git:20261016.b128771, 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.
