 ## Validation and failures
 
-After writing the target file, the tool builds it through [`Light.GuardClauses.SourceValidation`](../tools/source-export/Light.GuardClauses.SourceValidation/) using `netstandard2.0` or `net10.0` to match the selected source target.
+After writing the target file, the tool builds it through [`Light.GuardClauses.SourceValidation`](../tools/source-export/Light.GuardClauses.SourceValidation/) using `netstandard2.0` or `net10.0` to match the selected source target. Set `ValidateGeneratedFileBuild` to `false` to skip this validation when the caller will validate the output separately.
 
 If generation throws, the tool prints the exception and returns a non-zero exit code. If validation fails, it prints the captured build output and returns the build's non-zero exit code. In either case, a file already generated is left in place for diagnosis. Do not publish or commit custom output unless the command and matching validation complete successfully.
