Use this skill for any Kusto query or telemetry investigation specifically related to Fluid Framework or its partners. Triggers include: writing or running a Kusto query against the Office Fluid database, investigating Fluid Framework telemetry or error rates, querying Office_Fluid_FluidRuntime_* tables, looking up a Fluid session by Session_Id or docId, investigating a Fluid-related error in Loop or Whiteboard telemetry, monitoring an FF bump or partner ring deployment, checking Fluid render reliability or Scriptor errors, or when the user mentions Fluid-specific tables (Office_Fluid_FluidRuntime_*, OwhLoads, HostTracker, Scriptor) or Fluid-specific error types (dataCorruptionError, dataProcessingError, DeltaConnectionFailureToConnect, ICE, ACE). Do NOT trigger for general Kusto questions that are not related to Fluid Framework.
