It has everything to do with your prompt and why Claude Code has a plan mode: because the quality of your planning, prompting, and inputs significantly affects the output.
replyYour assertion, then, is that even a 1 sentence prompt is as good as a 5 section markdown spec with detailed coding style guidance and feature, by feature specification. This is simply not true; the detailed spec and guidance will always outperform the 1 sentence prompt.
No, I use plan mode and have several rounds of conversation with it, but lately I've been doing tasks where it does tons of independent research and finds complicated conclusions in an existing old codebase. I don't really feel like either of those count as "a prompt".
replyThe plan mode is useful because if you do corrections during development mode it does that silly thing where it leaves comments referring to your corrections.
