## When Writing Code

- **Always pass `client` when instantiating a resource** — `client: DynamicClient` is required on `Resource` / `NamespacedResource` (and on `.get()` / `Event` APIs). Create it with `get_client()` (or `get_client(fake=True)` in tests); do not rely on implicit kubeconfig/client creation.
- No client-side validation in `to_dict()` — let the K8s/OCP API server return errors. Helper functions in resource classes CAN validate.
- Context managers for auto-cleanup: `with Pod(name="test", namespace="default") as pod:`
- Context managers for auto-cleanup: `with Pod(client=client, name="test", namespace="default") as pod:`
- Wait utilities: `wait_for_status()`, `wait_for_condition()` via timeout-sampler
- Sensitive data: add keys to `keys_to_hash` property for automatic log hashing
- Fake client for tests: `get_client(fake=True)` — no cluster required

## When Reviewing Code

- Verify resources are constructed with an explicit `client=` (and `.get()` / `Event` calls pass `client`)
- Verify generated code markers are intact — no manual edits between markers
- Check type hints on all new functions/parameters
- Verify tests exist for new helper methods (not needed for generated `__init__`/`to_dict`)

Reject positional arguments after client in Event APIs. These signatures accept positional namespace and selector arguments. A legacy second positional client value can bind to namespace instead of raising the required clear TypeError. Add * after client and test this contract.

  • ocp_resources/event.py#L21-L21: make arguments after client in Event.get keyword-only.
  • ocp_resources/event.py#L120-L121: make arguments after client in Event.list keyword-only.
  • ocp_resources/event.py#L158-L158: make arguments after client in Event.delete_events keyword-only.
