# Ansight Logging Skill For Serilog

Use this skill when a user wants Serilog events to appear in Ansight session data.

## Goal

Attach an Ansight sink to the existing Serilog pipeline so application logs are mirrored into Ansight with `Runtime.Event(...)`.

## Required Constraints

- keep existing Serilog sinks and enrichers intact
- add an Ansight sink to Serilog; do not try to forward Ansight diagnostics out and stop there
- map Serilog levels into `AppEventType`
- emit exception events separately when `LogEvent.Exception` is present

## Workflow

1. Inspect the current `LoggerConfiguration`.
2. Add an `ILogEventSink` implementation that forwards log events into Ansight.
3. Map log levels:
   - `Verbose` and `Debug` -> `AppEventType.Debug`
   - `Information` -> `AppEventType.Info`
   - `Warning` -> `AppEventType.Warning`
   - `Error` and `Fatal` -> `AppEventType.Error`
4. Preserve the rest of the logging pipeline.
5. Build and verify the app.

## Implementation Pattern

```csharp
Log.Logger = new LoggerConfiguration()
    .WriteTo.Sink(new AnsightSerilogSink())
    .CreateLogger();
```

In real integrations, keep any existing `WriteTo` sinks and enrichers already configured by the app.

## Done Criteria

- Serilog events appear in Ansight timelines
- existing Serilog sinks continue to receive the same events
- level mapping is consistent
- exceptions are mirrored into Ansight
