Brainstorming

Brainstorming Skill

Turns a vague request into an approved design through focused Socratic questioning and tradeoff-honest alternatives. Does NOT permit any code to be written until the user has explicitly approved the design.

When to Use

• User describes a new feature or project.
• Requirements are unclear, conflicting, or ambiguous.
• An architectural decision needs to be made.
• Re-designing after a failed or rejected approach.
• User says "I want to build…", "let's make…", or "new feature".
• NOT when the user explicitly asks to skip design and prototype.

Prerequisites

• The edit tool to save the approved design.
• The ask_user tool to gather clarifications without spamming prose.
• A target file for the design (typically tasks/todo.md or docs/design.md).
• The user is actually available to respond — no design loops with a phantom user.

How to Run

1. Ask 3–5 Socratic questions to surface the real problem.
2. Present 2–3 alternative approaches with honest tradeoffs.
3. Recommend ONE with reasoning.
4. Walk the design in chunks: overview → architecture → data → API → edges.
5. Get explicit approval ("approved", "go", "ship it") before saving.
6. Save the approved design. Hand off to `executing-plans`.

Quick Reference

Procedure

Step 1: Socratic Questions (3–5 max)

Use the ask_user tool. Ask focused questions one at a time. Stop at five. More than five feels like interrogation.

Step 2: Present Alternatives

## Approaches

### Option A: <name>
- Pros: <…>
- Cons: <…>
- Effort: <rough estimate>

### Option B: <name>
- Pros: <…>
- Cons: <…>
- Effort: <rough estimate>

**Recommendation:** Option B — <specific reason>.

Be honest about tradeoffs. A fake "Option A" you do not believe in undermines trust.

Step 3: Walk the Design in Chunks

Present overview → architecture → data → API → edges. Pause for feedback after each chunk. Do not dump a 500-line document in one message.

Step 4: Get Explicit Approval

"Maybe" is not approval. "I'm not sure" is not approval. Ask what is bothering them and iterate. Only proceed when the user says "approved", "go ahead", "ship it", or equivalent.

Step 5: Save the Approved Design

Use edit to write to docs/design.md or tasks/todo.md:

## Approved Design: <feature>
Date: <YYYY-MM-DD>
Status: Approved

### Problem
<what we're solving>

### Solution
<what we're building>

### Architecture
<how it fits together>

### Acceptance Criteria
- [ ] <criterion 1>
- [ ] <criterion 2>

Hand off to the plan-before-code or executing-plans skill.

Pitfalls

• DO NOT start writing code while the design is still under discussion.
• DO NOT interrogate the user — five questions per round, maximum.
• DO NOT present a single "approach" with no alternatives. That is a decree, not a design discussion.
• DO NOT dump a 300-line design in one message. Chunk it.
• DO NOT treat "maybe" as consent. Get the word "approved".

Verification

• At least 3 Socratic questions were asked and answered.
• At least 2 alternatives were presented with honest tradeoffs.
• Design was walked in chunks with user feedback between them.
• Explicit approval ("approved" / "go ahead") is captured.
• Approved design is saved to docs/design.md or tasks/todo.md.
