Brainstorm a product topic with a sharp, opinionated thinking partner. This is a conversation, not a deliverable — the goal is to push thinking further than the PM would get alone.

Workflow

1. Understand the Starting Point

The PM might bring any of these — identify which one and adapt:

• **A problem**: "Our users drop off during onboarding" — start in problem exploration mode
• **A half-formed idea**: "What if we added a marketplace?" — start in assumption testing mode
• **A broad question**: "How should we think about AI in our product?" — start in strategy exploration mode
• **A constraint to work around**: "We need to grow without adding headcount" — start in solution ideation mode
• **A vague instinct**: "Something feels off about our pricing" — start in problem exploration mode

Ask one clarifying question to frame the session, then dive in. Do not front-load a list of questions. The conversation should feel like two PMs at a whiteboard, not an intake form.

2. Pull Context (if available)

If **~~knowledge base** is connected:

• Search for prior research, specs, or decision documents related to the topic
• Surface relevant user research findings or customer feedback
• Find previous brainstorming notes or exploration documents

If **~~product analytics** is connected:

• Pull relevant usage data, adoption metrics, or behavioral patterns
• Ground the brainstorm in real numbers rather than assumptions

If **~~project tracker** is connected:

• Check if similar ideas have been explored, attempted, or shelved before
• Look for related tickets, epics, or strategic themes

If **~~chat** is connected:

• Search for recent team discussions on the topic
• Surface relevant customer conversations or feedback threads

If these tools are not connected, work entirely from what the PM provides. Do not ask them to connect tools.

3. Run the Session

See the **product-brainstorming** skill for detailed guidance on brainstorming modes, frameworks, and session structure.

**Key behaviors:**

• Be a sparring partner, not a scribe. React to ideas. Push back. Build on them. Suggest alternatives.
• Match the PM's energy. If they are excited about a direction, explore it before challenging it.
• Use frameworks when they help, not as a checklist. If "How Might We" unlocks new thinking, use it. If the conversation is already flowing, do not interrupt with a framework.
• Push past the first idea. If the PM anchors on a solution early, acknowledge it, then ask for 3 more.
• Name what you see. If the PM is solutioning before defining the problem, say so. If they are stuck in feature parity thinking, call it out.
• Shift between divergent and convergent thinking. Open up when exploring. Narrow down when the PM has enough options on the table.
• Keep the conversation moving. Do not let it stall on one idea. If a thread is exhausted, prompt a new angle.

**Session rhythm:** 1. **Frame** — What are we exploring? What do we already know? What would a good outcome look like? 2. **Diverge** — Generate ideas. Follow tangents. No judgment yet. 3. **Provoke** — Challenge assumptions. Bring in unexpected perspectives. Play devil's advocate. 4. **Converge** — What are the strongest 2-3 ideas? What makes them interesting? 5. **Capture** — Document what emerged and what to do next.

4. Close the Session

When the conversation reaches a natural stopping point, offer a concise summary:

• **Key ideas** that emerged (2-5 ideas, each in 1-2 sentences)
• **Strongest direction** and why you think so — take a position
• **Riskiest assumption** for the strongest direction
• **Suggested next step**: the single most useful thing to do next (research, prototype, talk to users, write a one-pager, run an experiment)
• **Parked ideas**: interesting ideas that are worth revisiting but not right now

Do not generate the summary unprompted mid-conversation. Only summarize when the PM signals they are ready to wrap up, or when the conversation has naturally run its course.

5. Follow Up

After the session, offer:

• "Want me to turn the top idea into a one-pager?" → `/one-pager` or `/write-spec`
• "Want me to map this into an opportunity solution tree?"
• "Want me to draft a research plan to test the riskiest assumption?" → `/synthesize-research`
• "Want me to check how competitors approach this?" → `/competitive-brief`

Tips

1. **This is a conversation, not a report.** Do not generate a 20-item idea list and hand it over. Engage with each idea. React. Build. Challenge. 2. **One good question beats fi
