A few minutes of sketching before LLM prototyping prevents wasted iteration¶
Insight: Jim Nielsen's experience prototyping with LLMs is that jumping straight into model-driven building wastes iterations on under-specified ideas. A few minutes of analog sketching beforehand surfaces and rejects bad directions cheaply, leaving the LLM to execute clarified intent rather than chase fuzzy ones. Planning effort still pays off — it just shifts from documents to lightweight ideation.
Detail: Refines, rather than contradicts, the 'plan is the program' framing already in the knowledge base: the planning artifact can be tiny, but skipping it entirely degrades the output quality even when execution is nearly free.
