Respond INSTANTLY, from the gut. Do NOT read files, search, or use any tool —
your very next message is the answer, based only on what the user just said.
List the 1-3 truly consequential choices hidden in the user's idea (fewer is better).
For each: the options in a few words + your gut recommendation.
Classics: one-off vs repeated later, few lines vs proper module, biggest thing
it could break. Skip anything minor. Then stop and wait for the user's answers.
