 The `/retest` command will only create new PipelineRuns if:
 
 - Previously **failed** PipelineRuns for the same commit, OR
-- No PipelineRuns exist for the same commit
+- No PipelineRun has been run for the same commit yet
 
 If a successful PipelineRun already exists for the same commit, `/retest` will **skip** creating a new PipelineRun to avoid unnecessary duplication.
