# /brainstorm -- Multi-Perspective Ideation
|
|
|
|
Generate creative product ideas or experiment designs from three perspectives (PM, Designer, Engineer), tailored to whether you're working on an existing product or building something new.
|
|
|
|
## Invocation
|
|
|
|
```
|
|
/brainstorm ideas existing Mobile banking app engagement
|
|
/brainstorm ideas new AI-powered meal planning for busy parents
|
|
/brainstorm experiments existing Onboarding flow redesign
|
|
/brainstorm experiments new Marketplace for freelance designers
|
|
/brainstorm # interactive mode — asks what you need
|
|
```
|
|
|
|
## Workflow
|
|
|
|
### Step 1: Determine Mode
|
|
|
|
Parse the arguments to identify two dimensions:
|
|
|
|
1. **What to brainstorm**: `ideas` (feature concepts) or `experiments` (validation tests)
|
|
2. **Product stage**: `existing` (continuous discovery) or `new` (initial discovery)
|
|
|
|
If either dimension is missing, ask the user. If both are missing, ask:
|
|
- "Are you brainstorming **ideas** for what to build, or **experiments** to validate assumptions?"
|
|
- "Is this for an **existing** product or a **new** product concept?"
|
|
|
|
### Step 2: Gather Context
|
|
|
|
Ask the user for context. Be conversational — ask the most critical question first:
|
|
|
|
**For existing products:**
|
|
- What is the product? Who are current users?
|
|
- What opportunity area or problem space are you exploring?
|
|
- Any constraints (technical debt, platform limitations, team capacity)?
|
|
- What has been tried before?
|
|
|
|
**For new products:**
|
|
- What is the product concept? What problem does it solve?
|
|
- Who is the target user? What's their current alternative?
|
|
- What stage are you at? (napkin sketch, validated problem, early prototype)
|
|
- What are the riskiest assumptions?
|
|
|
|
Accept context from uploaded files (PRDs, research docs, strategy decks), pasted text, or conversation.
|
|
|
|
### Step 3: Generate Output
|
|
|
|
**If brainstorming ideas** — apply the **brainstorm-ideas-existing** or **brainstorm-ideas-new** skill:
|
|
- Generate ideas from three perspectives: Product Manager (user value, business impact), Designer (UX, delight, accessibility), Engineer (technical innovation, platform leverage, scalability)
|
|
- For each idea: name, description, target user impact, feasibility assessment
|
|
- Rank the top 5 ideas with rationale
|
|
- Flag which ideas could be quick wins vs. strategic bets
|
|
|
|
**If brainstorming experiments** — apply the **brainstorm-experiments-existing** or **brainstorm-experiments-new** skill:
|
|
- For existing products: suggest A/B tests, prototypes, fake-door tests, wizard-of-oz, concierge experiments, and spikes
|
|
- For new products: create XYZ+S hypotheses and suggest pretotype experiments (landing pages, explainer videos, pre-orders, concierge MVPs)
|
|
- For each experiment: hypothesis, method, success criteria, effort estimate, expected timeline
|
|
- Rank by learning-per-effort ratio
|
|
|
|
### Step 4: Deepen and Iterate
|
|
|
|
After presenting initial results, offer:
|
|
- "Want me to **detail** any of these ideas into a fuller spec?"
|
|
- "Should I **identify assumptions** behind the top ideas?" (chains into the `identify-assumptions-existing` or `identify-assumptions-new` skill)
|
|
- "Want to **design experiments** to validate the top ideas?" (chains into experiment mode)
|
|
- "Should I **prioritize** these against your current backlog?" (chains into the `prioritize-features` skill)
|
|
|
|
## Output Format

|
## Notes
|
|
|
|
- For existing products, ground ideas in current user behavior and validated problems
|
|
- For new products, focus on desirability and feasibility risks first
|
|
- If the user uploads a research doc or interview transcript, extract insights before brainstorming
|
|
- Encourage breadth first, then depth — generate many ideas before evaluating
