Audits a SQL Server migration plan with 15 checks (Y1-Y15) for version, edition, platform, and source-topology compatibility, then dispatches to sqlmigration-security-review, sqlmigration-objects-review, and other specialised skills for overlap areas. Use this skill when a user is planning, mid-flight on, or validating a SQL Server migration via backup/restore or log shipping/Always On seeding, mentions moving databases between instances/editions/versions, off a Failover Cluster Instance, or to Azure SQL, or asks "what breaks if I migrate to X". Trigger whenever migration readiness, cross-version compatibility, or cutover risk is the topic.

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, plan cache object growth, batch request baseline shifts, client cancellation rate, and counter collection integrity. Use this skill when a .blg or relog CSV is supplied, when sys.dm_os_performance_counters output is pasted, when CPU is high but no query explains it, when the host is suspected rather than the database, or when asked whether SQL Server or something else on the server is consuming the machine.
