Brainstorming Ideas Into Designs and Specs

Process

Understanding the idea:

Before asking any question, ask yourself: What decision does this answer unlock? What assumption am I testing? If you can't name one, skip the question. Always state the reason when you ask.

• Check the current project state first (files, docs, recent commits) — don't ask what already exists

• One question per message; prefer multiple choice, but explain what range of answers would change your approach

Exploring approaches:

Before proposing options, ask yourself: Is there one clearly dominant choice? If yes, state it with your confidence rather than manufacturing false balance.

• For each approach, make trade-offs explicit: what you gain, what you give up, and under what conditions it wins or loses

• Lead with your recommendation and explain what about this specific situation makes it the right call — not generic pros/cons

Presenting the design:

Before presenting, ask yourself: What's the single most likely thing I got wrong? Name it explicitly and ask about it first.

• Scale sections to complexity: a few sentences if straightforward, up to 200-300 words if nuanced

• Check in after each section before moving on

• Cover what's relevant: architecture, components, data flow — add error handling and testing only if non-trivial

When to Stop Asking

Stop and present the design when you have:

• What problem this solves and who is affected

• The smallest thing that would count as working

• At least one constraint that would have changed your default design

Keep asking when:

• The stated want and actual problem don't match (probe for the real constraint)

• You're about to add scope the user didn't ask for (challenge it first)

• "Just make it work" — always get one concrete success scenario before designing

If remaining questions are about implementation details, stop — make a decision and surface it explicitly in the design.

NEVER

• NEVER ask a question or make a design decision without explaining the reasoning behind it — the user needs to understand trade-offs to make good decisions, not just respond to prompts. Bad: "Should we use REST or GraphQL?" Good: "Should we use REST or GraphQL? — your answer determines whether I design around flexible querying or simple endpoint contracts."

• NEVER ask about implementation approach before understanding the problem — users anchor to the first solution they hear. Bad: jumping to "here are 3 database options" before knowing the access patterns.

• NEVER present a design without identifying the single most likely thing you got wrong and asking about that explicitly

• NEVER treat "I want X" as the requirement — probe for the actual constraint driving it. Bad: designing a cache because "it's slow"; good: discovering the real bottleneck is a single expensive query that runs on every page load.

• NEVER ask multiple questions in one message even if they seem related — pick the most important one

• NEVER skip asking what success looks like on open-ended features — it surfaces unstated acceptance criteria that would otherwise invalidate the design

• NEVER manufacture 2-3 options when one is clearly dominant — false balance signals indecision and wastes time
