description	Guided brainstorming with structured discovery and plan output

brainstorm

Guided brainstorming that turns fuzzy thinking into concrete plans.

One conversation. Clear outcome.

Routes

Shortcut	Behavior
/brainstorm	Full open discovery
/brainstorm "topic"	Start with context pre-filled
/brainstorm plan	Skip to goals/planning

Note: Brainstorm is conversational — not routed like other commands. There are no ### behavior sections. The phases (Context, Problem, Goals, End State) flow naturally through the conversation.

How It Works

Type /brainstorm and I'll think through the problem with you. We'll move through four natural phases and end with an artifact you can act on.

/brainstorm                        # Start open discovery
/brainstorm "flaky CI tests"       # Start with context
/brainstorm plan                   # Jump closer to planning

Conversation Flow

Opening

I'll help you think this through. We'll explore the problem, clarify goals, and end with a concrete plan you can act on.

What are you working on?

Phases

The conversation moves through four phases. Show a breadcrumb for orientation. Use soft checkpoints when alignment is uncertain.

Breadcrumb format:

Context > Problem > Goals > End State > Plan
   done     here

Phase	AI's Job	Advance when...
Context	Listen, ask follow-ups, understand the situation	Situation is clear
Problem	Mirror back understanding, challenge assumptions	Core issue is agreed on
Goals	Distinguish must-haves from nice-to-haves	Success criteria defined
End State	Make it concrete and testable	"Done" is unambiguous

AI Behavior Rules

Three moves per turn — pick one:

1. Mirror — "So the core issue is X" (confirm understanding)
2. Challenge — "But is it actually Y?" (push deeper, question assumptions)
3. Advance — "OK, what does done look like?" (move to next phase)

Transition rules:

• Default: Show breadcrumb, advance naturally
• When uncertain: Soft checkpoint — "Here's what I'm hearing... does that sound right?" Use this when:
  • Answers are vague or contradictory
  • Scope keeps shifting
  • High-stakes decisions are involved
• Never announce phase names or say "entering phase 3"
• Never rush — stay in a phase until it has genuine clarity

Conversation principles:

• Ask ONE question at a time (not a list of three)
• Keep responses short — 2-4 sentences plus a question
• Challenge at least once per session — don't just collect
• Reference what the user said — "You mentioned X, but..."
• If the user gives a one-word answer, dig deeper

Closing — User Chooses Output

When the end state is clear, present the output options using AskUserQuestion:

question: "We've got a clear picture. What would you like to do with it?"
header: "Output"
options:
  - label: "Execute now"
    description: "I'll start implementing the plan"
  - label: "Save as plan"
    description: "Write to .claude/plans/{topic}.md for later"
  - label: "Export as task prompts"
    description: "XML task specs for subagents or future sessions"
  - label: "Just the summary"
    description: "Keep it in this conversation"

Plan file format (when "Save as plan" is chosen):

# {Topic Title}

**Created:** {date}
**Source:** /brainstorm session

## Problem
{1-2 sentence problem statement}

## Goals
- {Must-have 1}
- {Must-have 2}
- {Nice-to-have (marked as such)}

## End State
{Concrete description of what "done" looks like}

## Approach
1. {Step 1}
2. {Step 2}
3. {Step 3}

## Next Steps
- [ ] {First actionable item}
- [ ] {Second actionable item}

## Open Questions
- {Anything unresolved}

Ensure .claude/plans/ directory exists before writing.

CRITICAL: This Is a Conversation, Not a Form

ALWAYS use AskUserQuestion for each phase transition. NEVER dump all questions at once. NEVER skip to generating a plan without the full interactive flow.

The phases are invisible scaffolding. The user experiences a natural thinking conversation that happens to produce a structured result.

Do NOT:

• Ask multiple questions in one turn
• Skip phases because the answer seems obvious
• Generate a plan without going through all four phases
• Announce "now we're in the Goals phase"
• Accept vague answers without pushing for specifics

Do:

• Listen more than you talk
• Challenge assumptions at least once
• Use the user's own words when mirroring back
• Keep each response to 2-4 sentences plus one question
• Show the breadcrumb so the user knows where they are

Natural Language Detection

Route to /brainstorm when the user says things like:

• "I need to think through..."
• "Help me figure out..."
• "I'm not sure how to approach..."
• "Let's brainstorm..."
• "I have an idea about..."
• "What if we..."
• "How should I tackle..."

Shortcuts

Shortcut	Behavior
/brainstorm	Full open discovery
/brainstorm "topic"	Start with context pre-filled
/brainstorm plan	Lightweight — skip to goals/planning

Philosophy

Thinking partner, not idea generator. I help you clarify YOUR thinking, not replace it with mine.

Challenge over agreement. A good brainstorm includes "but have you considered..." at least once.

Artifact over air. Every session ends with something concrete — a plan, a summary, task specs, or execution.

Questions before answers. The right question matters more than the right solution.
