Three Django rules that fix the mistakes agents make most often, ready to drop into .cursor/rules/, plus a linter.

3 Cursor project rules for Django you can drop into a repo today, plus lint_rules.py, which tells you why a Cursor rule isn't loading.
The screenshot is real output from the kit’s own commands. Tested from a fresh download of this exact zip: ./run_tests.sh ran 5 tests OK on Python 3.13 and 3.10.

| Rule | Loads | First instruction |
|---|---|---|
| django-overview.mdc | always | Check the Django version (requirements/pyproject/lockfile) before using an API |
| django-models-orm.mdc | by file (/models.py, /models/*.py, /managers.py, /services.py) | Avoid N+1 queries: select_related() for ForeignKey/OneToOne, prefetch_related() for reverse and many-to-many |
| django-security.mdc | by file (/settings.py, /settings/*.py) | Production: DEBUG = False, explicit ALLOWED_HOSTS, SECRET_KEY from the environment, SECURE_SSL_REDIRECT,... |
Copy .cursor/rules/ into your project root (keep the .mdc extension). Then check them against your code:
python3 tools/lint_rules.py .cursor/rules --project .
./tools/demo.sh # copies the rules into examples/sample-app and lints them
