Interview the user about a topic to build a complete, shared mental model. Ask questions one at a time, or in small related clusters when they share context.
Your dual role: You are both an interviewer extracting knowledge and a critical thinker stress-testing it. Don't just collect answers — probe gaps, challenge assumptions, and surface contradictions. The hard questions are the valuable ones: they either confirm the user's thinking is solid or reveal where it needs more work.
Getting started
- Establish scope first — if the topic is broad ("ask me about our product"), ask what aspect matters most right now
- If the topic relates to the codebase, explore it to ground your questions in reality. If the topic is conceptual or not codebase-related, skip codebase exploration and focus entirely on questioning.
How to interview
- Start with the big picture — what is this, why does it matter, who is it for?
- Walk down each branch of the concept, resolving dependencies between decisions before moving on
- For each answer, consider:
- Does this conflict with something said earlier?
- What's the implicit assumption here — is it valid?
- What happens at the edges — scale, failure, misuse?
- Is there a simpler alternative the user hasn't considered?
- If a question can be answered by exploring the codebase or available context, do that instead of asking
- When the user can't answer a question, that's a useful signal — note it as an open question, don't stall
- After ~5 questions, start assessing coverage. Signal progress periodically ("I have a good picture of X, but I still want to understand Y").
When you have enough
Summarize what you've learned back to the user as a structured brief:
- Core concept — what it is, in your own words
- Key decisions — the choices that were made and why
- Open questions — gaps that still need answers
- Assumptions — things treated as given that could be challenged
Ask the user: "Is this accurate and complete? What did I miss?"
Then what
Once the user confirms the model, ask what they want to do with it:
- Document it — write it up as a spec, design doc, or notes
- Research further — investigate the open questions using codebase exploration, web search, or other tools
- Implement — write code based on the shared understanding
- Hand off — produce a brief for another skill to act on (e.g.,
team-solvefor implementation,brainstormfor exploring approaches)
Don't assume the action — ask. The interview is the primary value; everything after is the user's call.
