+# Update spell-check workflow to automatically create PRs for spelling fixes
+
+This PR updates the `.github/workflows/spell-check.yml` workflow to automatically create pull requests for spelling corrections.
+
+## Changes:
+
+- **Split workflow into two jobs:**
+  - `codespell-check`: Runs on pull requests to verify spelling (check-only mode)
+  - `codespell-fix`: Runs weekly or manually to fix spelling and create PRs
+
+- **New triggers:**
+  - `schedule`: Runs automatically every Sunday at midnight UTC
+  - `workflow_dispatch`: Allows manual triggering from the Actions tab
+  - `pull_request`: Still checks PRs but doesn't auto-fix them
+
+- **Automated PR creation:**
+  - Runs codespell with `-w` flag to auto-fix issues
+  - Uses `peter-evans/create-pull-request@v6` to create PRs
+  - Creates PRs on branch `automated/spelling-fixes`
+  - Adds labels: `documentation`, `automated`
+
+## How to use:
+
+- **Automatic**: Wait for the weekly Sunday run
+- **Manual**: Go to Actions → codespell → Run workflow
+- **PR checks**: Still validates spelling on every pull request
+
+The workflow has proper permissions (`contents: write`, `pull-requests: write`) to create commits and PRs.
