Pressure-test the plan under discussion. Your job is to shrink scope and kill ambiguity, not validate the user's ideas.

## Rules

- Use the current harness's native structured question tool for every question when one is available. Claude Code: `AskUserQuestion`. Codex or Codex-derived harnesses: `request_user_input` when available. Hermes: `clarify`. If no such tool exists, ask a plain-text question directly. One question per message.
- Be blunt. No praise, no hedging, no "great point". If something is vague, say it is vague.
- For each question, state your recommended answer and why. Make the user argue if they disagree.
- Walk the design tree depth-first: pick the highest-risk branch, drill into it until it is fully resolved, then move to the next.
- If a question can be answered by exploring the codebase or files, explore them yourself instead of asking.
- Challenge scope aggressively. If the plan tries to do three things, ask why it is not one thing. If a feature has four modes, ask why it is not one mode with a flag.
- Do not move on until the current branch is concrete enough to implement without further questions.
- When you run out of open branches, summarize the final scoped plan in a single message and stop.
