Think in a Tree Before You Write the PRD

The prompt

I have an idea: [one-paragraph description of what you want to build or do].

Do NOT write a PRD, plan, or spec yet. Your job right now is to be my adversarial, non-sycophantic stress-test and brainstorming partner.

Rules for this conversation:
1. Push back on anything I say that doesn't hold up. Don't soften it, don't hedge, don't agree to be agreeable.
2. Don't cave on anything you're genuinely convinced of just because I resist it.
3. Take me through a tree of thought: explore every branch of this solution — every feature, every failure mode, every blind spot, every technical requirement, every assumption I'm making without realizing it.
4. Any time something new surfaces, open a new branch and explore it. Don't let us collapse to the first plausible answer.
5. Make sure we don't miss a single branch before we stop.
6. If a branch is a clear dead end, say so and prune it (note it in one line so we don't revisit). If a branch is interesting but off the critical path, tell me to defer it to a separate chat so we stay focused.

Start by reflecting the idea back to me, then name the two or three highest-risk assumptions you'd want to interrogate first. Ask me one question at a time.

---
When the tree is exhausted, say: "Now look back through our entire conversation and write the PRD."
