brainstorm

Brainstorm

Collaborative discovery before planning. Answers WHAT to build and WHY — precedes /plan, which answers HOW.

Boundaries

This skill MAY: research (read-only), discuss, ask questions, write the brainstorm document. This skill MAY NOT: edit code, create files beyond the brainstorm document, run tests, deploy, implement anything.

NEVER write code during this skill. This is a discussion, not implementation.

Common Rationalizations

Shortcut	Why It Fails	The Cost
"Skip reframing — the user already knows what they want"	Users describe solutions, not problems. Without reframing, you build the wrong thing.	Days of rework when the real need surfaces
"Skip research — I'll brainstorm from scratch"	Reinventing what exists. The codebase has patterns, past brainstorms have context.	Wasted effort + inconsistency with existing decisions
"Keep exploring — we haven't found the perfect approach"	Diminishing returns. After 2-3 solid options, more exploration adds noise, not signal.	Analysis paralysis — nothing ships
"Let me just write some code to test this idea"	Brainstorming is for decisions, not prototypes. Code anchors you to an approach too early.	Premature commitment to the first thing that compiles

Phase 0: Assess Whether Brainstorming Is Needed

Entry: User has a topic or problem area.

Not everything needs a brainstorm.

If requirements are already clear and specific: Use AskUserQuestion with:

• question: "Your requirements seem clear enough for /plan. Brainstorm first, or go straight to planning?"

• header: "Approach"

• options:

  1. label: "Go to /plan (Recommended)", description: "Requirements are clear — skip brainstorming and start planning"
  2. label: "Brainstorm first", description: "Explore the problem space before committing to an approach"

• multiSelect: false

• If user selects Go to /plan → exit this skill, suggest /plan

• If user selects Brainstorm first → continue to Phase 1

Brainstorm when:

• The problem is ambiguous or has multiple valid approaches
• It's a significant feature with architectural implications
• The user isn't sure what they want yet
• There's real risk of building the wrong thing

Exit: Decision made — brainstorm or skip.

---

Phase 1: Reframe the Problem

Entry: User confirmed brainstorming is needed.

This is the critical step. Before exploring solutions, question the problem.

Use AskUserQuestion to ask ONE question at a time. Do not dump a questionnaire. Start with:

1. "What problem are we actually solving?" — Strip away assumptions. Get to the root need.
2. "Who has this problem and when?" — Context changes solutions.
3. "What does success look like?" — Not features, outcomes.

Continue asking until the problem is clear. Prefer multiple-choice questions when natural options exist. Validate assumptions explicitly: "I'm assuming X — correct?"

Exit: Problem statement is clear and reframed. Both you and the user agree on what you're solving.

Socratic Verification (High Challenge)

Before accepting the problem framing, apply Chain-of-Verification:

1. Generate 2-3 verification questions about the framing: "What would need to be true for this framing to be wrong?" "Is this the real problem, or a symptom?"
2. Answer each with evidence from past brainstorms, codebase patterns, or documented constraints.
3. Surface contradictions with past decisions: "This seems to conflict with [prior brainstorm]. Has the context changed?"
4. Use provisional confidence: "I see a potential issue with this framing — [evidence]. Worth exploring before we commit?"

Don't challenge obvious framings just to seem thorough. Challenge when you have evidence or genuine uncertainty.

See ../../super-intelligence/knowledge/socratic-patterns.md for technique details.

Phase 2: Research What Exists

Entry: Problem statement is clear (Phase 1 complete).

Check the project's CLAUDE.md for a "Toolkit Output Paths" table. Use those paths if present, otherwise use defaults.

Launch research agents in parallel:

• Task researcher("Find existing patterns related to: . Search docs/brainstorms/, docs/solutions/, docs/plans/, and codebase for similar features, past decisions, and prior art.")

Surface findings to the user:

>> Related brainstorm: docs/brainstorms/2026-02-15-notifications-brainstorm.md
>> Existing pattern: services/email-notifier/ (notification handling)
>> Past solution: docs/solutions/infrastructure/sse-auth-token-refresh.md

If no relevant findings: Say so. Don't invent relevance.

Exit: Findings presented. User has seen what exists before exploring approaches.

---

Phase 3: Explore Approaches

Entry: Research complete (Phase 2). User has context on what exists.

Through collaborative dialogue, explore 2-3 approaches. For each:

• What it optimizes for (speed, flexibility, simplicity, etc.)
• What it costs (complexity, maintenance, time, risk)
• Who's done this before (prior art in the codebase or industry)

Use AskUserQuestion to ask one question at a time. Start broad (purpose, users), narrow to specifics (constraints, edge cases).

If any open questions emerge: You MUST ask the user about each one. Do not assume answers or defer them silently.

Exit when:

• The approach is clear and the user signals a decision
• You've explored enough to choose (2-3 approaches with tradeoffs)
• The user says "proceed" or equivalent

Assumption Audit (after approach is chosen)

Once an approach is selected, run the Recursive Why loop before locking it in. This is mandatory — not optional.

The loop:

1. Extract assumptions — identify 3-5 things that must be true for this approach to work. These are often implicit: technical feasibility, team capability, data availability, user behavior, performance characteristics.

2. For each assumption, run the Recursive Why:

   Assumption: "We need real-time updates"
   → Why? "Because users expect instant feedback"
   → Why do they expect that? "Because... actually, we haven't validated this. A 5-second poll might be fine."
   → STOP: Hit "I don't know" — this is an unverified assumption.
   

3. Classify what you find:

   • Bedrock (verified, backed by evidence or hard constraint) → proceed with confidence
   • Unverified (believed but not proven) → flag to the user, ask whether to proceed, investigate, or mitigate
   • Weak (rests on habit or "that's how we do it") → challenge directly: "Is there a reason, or is this inertia?"

4. Surface to the user before moving to Phase 4:

   Assumption audit for [chosen approach]:
   ✓ Bedrock: PostgreSQL can handle the query pattern (verified in similar feature X)
   ? Unverified: Users need real-time updates (no data — assumed)
   ✗ Weak: "We always use WebSockets for this" (habit, not requirement)
   

5. Use AskUserQuestion if any unverified or weak assumptions are found:

   • question: "Found [N] unverified assumptions. How do you want to handle them?"
   • options: "Proceed anyway (accept the risk)", "Investigate before committing", "Reconsider approach"

Depth: 2-3 levels of "why" per assumption. Stop at bedrock, not at a fixed number.

See ../../super-intelligence/knowledge/socratic-patterns.md for evidence grounding and discovery-patterns.md → "Recursive Why" for the loop technique.

Phase 4: Capture Decisions

Entry: Approach chosen (Phase 3 complete).

For each decision made during brainstorming, capture:

• What was decided — the choice
• Why — the reasoning
• What was rejected — alternatives considered and why

Also capture:

• Open questions — things to resolve during planning or implementation
• Out of scope — things explicitly excluded

---

Phase 5: Write Brainstorm Document

Entry: Decisions captured (Phase 4 complete).

Output path: {brainstorms_path}/YYYY-MM-DD-{kebab-topic}-brainstorm.md (Default brainstorms_path: docs/brainstorms/)

Write the document with this structure:

---
title: "{Topic}"
type: brainstorm
date: YYYY-MM-DD
participants: [{who was involved}]
related:
  - {links to related brainstorms, plans, solutions found in Phase 2}
---

# {Topic}

## Problem Statement
{The actual problem, reframed from Phase 1}

## Context
{Key findings from Phase 2 — what exists, what's been tried}

## Chosen Approach
{High-level description of the selected approach}

## Why This Approach
{Decision rationale — what it optimizes for, why alternatives were rejected}

## Key Design Decisions

### Q1: {Decision topic} — RESOLVED
**Decision:** {What was decided}
**Rationale:** {Why}
**Alternatives considered:** {What else was explored and why it was rejected}

## Open Questions
{Questions that need to be answered during planning or implementation}

## Out of Scope
{Things explicitly excluded from this work}

## Next Steps
- `/plan` to create an implementation plan from these decisions

Memory Integration

Before writing, check if any decisions contradict past brainstorms surfaced in Phase 2. If a contradiction exists:

• Flag it explicitly in the document under the relevant Key Design Decision
• Note what changed: "Previously decided [X] in [brainstorm]. Now choosing [Y] because [context change]."

If a novel pattern was discovered during brainstorming (approach nobody's tried, new integration point, unexpected constraint), note it as a candidate for /compound in the Next Steps section.

Exit: Document written.

---

Phase 6: Handoff

Entry: Document written (Phase 5 complete).

Use AskUserQuestion with:

• question: "Brainstorm captured at {path}. What would you like to do next?"
• header: "Next step"
• options:
  1. label: "Proceed to /plan", description: "Turn these decisions into an implementation plan"
  2. label: "Keep exploring", description: "More questions or refine decisions before moving on"
  3. label: "Done for now", description: "Return later — to plan: /plan {brainstorm-path}"
• multiSelect: false

If user selects "Keep exploring": Return to Phase 3 and continue asking questions one at a time. When satisfied, update the document and return to this handoff.

If user selects "Proceed to /plan": Suggest running /plan {brainstorm-path}.

If user selects "Done for now": Confirm the path.

---

Validate

Before delivering the brainstorm document, verify:

• Problem was reframed — not just accepted at face value
• At least 2 approaches were explored with tradeoffs
• Assumption Audit ran on the chosen approach — assumptions classified as bedrock/unverified/weak
• No unverified or weak assumptions were silently accepted — user was asked about each
• Every decision has rationale and rejected alternatives documented
• Open questions are listed — nothing swept under the rug
• /plan can start from this document without asking "but what did you decide about X?"
• No code was written — only the brainstorm document was created

What Makes This Superpowered

• Problem Reframing (1.4): Questions the problem before solving it. Highest-leverage question: "What are we actually solving?"
• Opportunity Recognition (1.2): Researcher agent surfaces past work, patterns, and prior art before building new.
• AI-Augmented Discovery (1.3): Multi-source research synthesized into insights — connects dots across brainstorms, solutions, and code.
• AI Curiosity (1.1): Explores multiple approaches before committing. Rewards looking around, not jumping to the first idea.
