Plan mode is great, but to me that's just prompting your LLM agent of choice to generate an ad-hoc, imprecise, and incomplete spec.

The downside of specs is that they can consume a lot of context window with things that are not needed for the task. When that is a concern, passing the spec to plan mode tends to mitigate the issue.
