+# Recent Workflow Documentation Creator
+
+This workflow automatically creates GitHub pull requests to document recently deployed Vellum workflows.
+
+## Description
+
+A scheduled workflow that runs daily to:
+1. Fetch all workflow deployments created in the last 24 hours
+2. Process each deployment by fetching its workflow code
+3. Use a GitHub agent to create pull requests with workflow examples
+
+## Key Features
+
+- **Scheduled Trigger**: Runs automatically at 10:00 AM Mountain Time daily
+- **Map Node Pattern**: Processes multiple deployments concurrently (max concurrency of 4)
+- **Tool-Calling Agent**: Uses Claude with GitHub integration tools to:
+  - Create new branches
+  - Commit workflow code and README files
+  - Open pull requests
+- **Parallel Outputs**: Returns multiple outputs simultaneously (PR URLs, comments, deployments JSON)
+
+## Workflow Structure
+
+```
+Scheduled Trigger → FetchRecentDeployments → ProcessDeployments (Map) → {
+    DeploymentsOutput,
+    CommentsOutput,
+    PrUrlsOutput
+}
+```
+
+## Notable Patterns
+
+1. **Subworkflow with Map Node**: The `ProcessDeployments` node is a Map Node that contains its own subworkflow for processing each deployment.
+
+2. **Vellum Integration Tools**: Uses `VellumIntegrationToolDefinition` with Composio's GitHub integration for branch/file/PR operations.
+
+3. **Custom Node Display**: Nodes use custom icons and colors for better visual organization in the UI.
+
+4. **API Client Access**: Accesses the Vellum client via `self._context.vellum_client` for fetching deployment data.
+
+## Use Case
+
+This workflow is perfect for teams who want to automatically document their workflows as they're deployed, maintaining an up-to-date examples repository without manual intervention.
