+## ⚠️ CRITICAL: Always Run Pre-commit Before Pushing
+
+**ALWAYS run `pre-commit run --all-files` before pushing commits.** CI will fail if pre-commit checks don't pass. This is non-negotiable.
+
+```bash
+# Stage your changes first
+git add .
+
+# Run pre-commit on all files
+pre-commit run --all-files
+
+# If there are auto-fixes, stage them and commit
+git add .
+git commit --amend  # or new commit
+```
+

+- **Type errors** - mypy failures need manual fixes
+- **Linting** - ruff, pylint issues need manual fixes
