sqlperfmon-review SKILL.md skillB
sqlperfmon-review from vanterx/mssql-performance-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it. Analyze Windows Performance Monitor counter data for a SQL Server host to establish whether the operating system itself is the bottleneck and which process is responsible. Applies 14 checks (PM1-PM14) covering SQL process CPU saturation, non-SQL CPU competition, privileged/kernel time, page life expectancy, virtual address space growth, OS memory exhaustion, logical disk latency, hot volumes masked by the _Total instance, compilation and recompilation rates expressed against batch throughput…

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 Perfmon Counter Review Skill ## Purpose Determine whether the operating system hosting SQL Server is itself the constraint, and attribute the consumption to a process. Applies 14 checks (PM1-PM14) across five categories: - **PM1-PM3** - CPU attribution: SQL Server process saturation, non-SQL process competition, and privileged/kernel time that points outside the engine - **PM4-PM6** - Memory: page life expectancy, virtual address space growth against committed memory, and OS-level memory exhaustion - **PM7-PM8** - Storage: logical disk latency per volume, and a hot volume hidden behind the `_Total` instance - **PM9-PM12** - Compilation and workload: compile and recompile rates expressed against batch throughput, plan cache object growth by cache type, and batch request baseline shifts - **PM13-PM14** - Client behaviour and collection integrity: attention (cancellation) rate, and gaps or too-short a sample window in the capture itself …

How to install
mdr add vanterx/mssql-performance-skills/sqlperfmon-review@git:20261006.86bfc4emdr add vanterx/mssql-performance-skills/sqlperfmon-review@sha256:2ca1870622322153Pin to a label like 1.0.0, or to a sha256 fingerprint for the exact contents. Either way, the exact version is written to mdr.lock. mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
