 Use workflows that run on push events to automate reactive maintenance tasks like updating API references or identifying documentation updates needed for new features.
 </Tip>
 
+## Run history
+
+The [Workflows](https://dashboard.mintlify.com/products/workflows) page in the dashboard has a **Run history** tab that shows a unified view of all workflow runs across your project.
+
+Each run displays:
+
+- **Time** — when the workflow ran.
+- **Workflow** — which workflow triggered the run.
+- **Status** — the current state of the run: queued, running, failed, PR merged, PR closed, review needed, or no action needed.
+- **Summary** — a brief description of what the agent did.
+
+Use the workflow filter dropdown to view runs for a specific workflow. By default, the run history shows only runs with open pull requests. Toggle **Show all runs** to include runs where the pull request was already merged or closed.
+
+### Close a pull request
+
+If a workflow run opened a pull request that you don't want to merge, you can close it directly from the run history table without navigating to GitHub. Click the **Close PR** button on the run entry.
+
+### View changes in the editor
+
+Each run links to its branch in the dashboard editor so you can review the agent's changes before merging.
