+## Workshop Format: Interview Mode
+
+When the workshop brief specifies `**Format:** Interview` (or the user requests "interactive interview mode"), the between-rounds flow changes for the interview round:
+
+### How Interview Mode Works
+
+Instead of agents writing responses to each other, the facilitator (team lead) conducts a live interview with the user:
+
+1. **Collect all agent questions** — Read all Round 1 output files to gather every question.
+2. **Group thematically** — Organize questions into 5-7 thematic clusters (e.g., "The Vision," "The Confusion Type," "The Emotional Loop"). Questions from different agents that probe similar territory go together.
+3. **Present via AskUserQuestion** — Present each group using the `AskUserQuestion` tool, one group at a time (1-3 questions per group). For each question:
+   - Include the asking agent's name and domain
+   - Include the full question text with context
+   - Include the agent's reasoning for why the question matters
+   - Provide 2-4 option choices that represent distinct answer categories
+   - Always allow free-text via the "Other" option (automatic)
+4. **Capture nuance** — The user's free-text notes often contain the most important insights. Capture these verbatim in the transcript.
+5. **Summarize between groups** — After each group, briefly reflect back the key finding before moving to the next group.
+6. **Write full transcript** — When all groups are done, write the complete interview to `docs/workshops/{name}/lead-interview.md` with:
+   - Every question and full answer (verbatim where the user provided free text)
+   - Key findings per answer
+   - An interview summary section with the major revelations
+   - "What Survives" and "What Changes" sections
+
+### Why AskUserQuestion
+
+The user CANNOT see agent messages, task details, or file contents in the conversation. They only see your text output and AskUserQuestion prompts. Present all question context directly — never assume the user has read agent outputs.
+
+### Distributing Interview Results
+
+When creating Round 3 (proposal) tasks after an interview round, include the full transcript path and a summary of the major reframe in every agent's task description. If the user requests it, instruct agents to read the verbatim transcript.
