+## Retry a failed run
+
+If a workflow run fails, you can retrigger it from the dashboard without waiting for the next scheduled run or push event. Retriggering reruns the workflow with the same trigger context as the original run, so the agent receives the same repository, branch, and pull request information.
+
+You can retry runs from scheduled (cron), manual, and merge triggers. You cannot retry successful runs or runs from disabled or deleted workflows.
+
+1. Go to the [Workflows](https://dashboard.mintlify.com/products/workflows) page in your dashboard.
+2. Click a workflow to open its run history.
+3. Find a run with a **Failed** status and click **Retry**.
+
+The new run appears in the run history with its own status. Retriggered runs count toward your monthly run limit if they succeed.

 Each workflow keeps a log of past runs, including the status and a summary of changes made.
