+## Cleaning Submodule Credentials
+
+By default, generated checkout steps set `persist-credentials: false`, which causes `actions/checkout` to remove credentials in its post-step. In repositories with submodules or sparse checkouts, that post-step can fail with missing submodule URL or path errors.
+
+Set `force-clean-git-credentials: true` on a checkout target to opt into an explicit cleanup step instead. The compiler emits the checkout with `persist-credentials: true`, then injects a `Clean git credentials after checkout` step immediately after it. The cleanup removes the credential helper and `http.*.extraheader` entries from both `.git/config` and any `.git/modules/*/config`, including nested submodules.
+
+```yaml wrap
+checkout:
+  - repository: org/monorepo-with-submodules
+    submodules: recursive
+    force-clean-git-credentials: true
+```

 ## Checkout Merging
 
 Multiple `checkout:` configurations can target the same path and repository. This is useful for monorepos where different parts of the repository must be merged into the same workspace directory with different settings (e.g., sparse checkout for some paths, full checkout for others).

 ## Troubleshooting
 
 - **Branch not created**: Ensure `create-orphan: true` or create manually.
-- **Validation failures**: Match `file-glob`, stay under `max-file-size` (10KB default), `max-file-count` (100 default), and `max-patch-size` (10KB default).
+- **Validation failures**: Match `file-glob`, stay under `max-file-size` (100KB default), `max-file-count` (100 default), and `max-patch-size` (10KB default).
 - **Patch too large**: If the total diff exceeds `max-patch-size` (default 10KB), the push is rejected. Reduce the number or size of changes, or increase `max-patch-size` in the configuration.
 - **Changes not persisting**: Check directory path, workflow completion, push errors in logs.
 - **Merge conflicts**: Concurrent pushes are handled: if another run has pushed since the branch was checked out, the GraphQL mutation replays your file diff on top of the latest remote state (your changes win).
