[**CriticalError**]

Potential KeyError: `fetch_prompt` returns `prompt_config["commit"]` but if the API call succeeds but returns a response without the "commit" key, this will raise a KeyError. The API type shows `PromptFetchResponse` has `commit` as `NotRequired[Optional[PromptCommitInfo]]`, meaning it might not be present in the response.

Potential KeyError in dictionary access: The `Prompt.get()` method assumes all expected keys exist in `prompt_config` without validation. If the API response is missing required fields like "name", "prompt", "tags", etc., this will raise a KeyError.

The assertion messages here are misleading. The test correctly asserts that the prompts are listed from newest to oldest (v3, v2, v1), but the failure messages state the opposite order. Updating them will improve clarity if this test fails in the future.

```suggestion
    assert prompt_list[0].prompt == "version 3", "First prompt in list should be the latest (version 3)"
    assert prompt_list[1].prompt == "version 2", "Second prompt in list should be version 2"
    assert prompt_list[2].prompt == "version 1", "Third prompt in list should be the oldest (version 1)"
```
