# 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.

```bash
/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`:

```yaml
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):

```markdown
# {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.
