+## Deterministic Body Footers
+
+Use `body-footer` on `create-issue` or `create-pull-request` to append workflow-defined content after the agent-generated body:
+
+```yaml wrap
+safe-outputs:
+  create-issue:
+    body-footer: |
+      ---

+  create-pull-request:

+      ---
+      Review the generated changes before merging.
+```
+
+The body footer is appended even when `footer: false`. It is the final visible content in the body; hidden workflow metadata remains after it. The template supports `{workflow_name}` and `{run_url}` placeholders.
+
 ## PR Review Footer Control
 
 For PR reviews (`submit-pull-request-review`), the `footer` field supports conditional control over when the footer is added to the review body:
