Brainstorming Ideas Into Designs

When to Use

• Before any creative work: creating features, building components, adding functionality, or modifying behavior
• User says "design a feature," "build a new," "explore approaches"
• NOT for: bug fixing (systematic-debugging), extracting existing knowledge (expert-interviewer), choosing between known options (debate)

Turn ideas into fully formed designs through collaborative dialogue. Understand context, ask questions one at a time, present design, get approval.

Wrong skill? Bug fixing → systematic-debugging. Extracting existing knowledge → expert-interviewer. Choosing between known options → debate.

Ensemble Mode (Multi-Perspective)

For broad, ambiguous, or high-impact prompts, brainstorming can activate ensemble mode — dispatching parallel perspective lenses (Product, Architecture, Reliability, Security, Simplicity, Contrarian) for richer exploration. See references/ensemble-mode.md for full protocol.

Activation: Apply skills/_shared/multi-agent-activation-rubric.md. Score ≥ 6 → ensemble. Score = 5 → ask user. Score < 5 → single-agent (this checklist). Cost cap: 1.5× single-agent tokens. Max lenses: 4.

Do NOT write any code or take implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.

Checklist (complete in order)

1. Explore project context — check files, docs, recent commits
2. Assess scope — if multiple independent subsystems, decompose first
3. Ask clarifying questions — one at a time, prefer multiple choice, understand purpose/constraints/success criteria
4. Propose 2-3 approaches — with trade-offs and your recommendation
5. Present design — in sections scaled to complexity, get approval after each section
6. Write design doc — save to docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md, commit
7. Spec review loop — dispatch spec-document-reviewer subagent; fix issues; max 3 iterations then escalate to human
8. User reviews written spec — ask user to review before proceeding
9. Transition — invoke plan-and-execute skill (or debate first if ≥3 viable approaches need formal comparison)

Understanding the Idea

• Check current project state first (files, docs, commits)
• If project too large for single spec, help decompose into sub-projects
• Ask one question per message
• Focus on: purpose, constraints, success criteria

Exploring Approaches

• Propose 2-3 different approaches with trade-offs
• Lead with your recommendation and explain why

Presenting the Design

• Scale each section to its complexity
• Ask after each section whether it looks right
• Cover: architecture, components, data flow, error handling, testing
• Design for isolation: smaller units with clear purpose and well-defined interfaces

Working in Existing Codebases

• Explore current structure before proposing changes — follow existing patterns
• Include targeted improvements for problems affecting the current work
• Don't propose unrelated refactoring

After the Design

1. Write spec to docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md
2. Run spec review loop (subagent reviewer, max 3 iterations)
3. User reviews written spec
4. If ≥3 viable approaches emerged — invoke debate to formally compare and red-team the already-surfaced approaches (NOT to generate new ones)
5. Invoke plan-and-execute skill for implementation plan

Key Principles

• One question at a time — don't overwhelm
• YAGNI ruthlessly — remove unnecessary features
• Explore alternatives — always 2-3 approaches
• Incremental validation — present, approve, move on

Example: Design Spec Output

# Design: Feature Name
## Approach: [Selected approach with rationale]
## Components: [Architecture, data flow, interfaces]
## Testing: [Strategy, edge cases]
## Status: Approved → invoke writing-plans

Failure Modes

Failure	Fix
Started coding before design approval	Delete code, restart from checklist step 3
Presented one approach as fait accompli	Back up, generate 2-3 alternatives with trade-offs
Skipped spec review loop	Dispatch spec-document-reviewer sub-agent before proceeding
