brainstorming

name	brainstorming
description	Use when exploring design options, starting new features, or needing to think before coding. Two modes: design (explore approaches with trade-offs) and challenge (stress-test decisions). No implementation until design is approved.

Brainstorming

GATE: no code, no files, no impl until design presented and approved.

Design Mode (default)

1. Explore context -- read files, docs, recent commits
2. Clarify -- one question at time, not list
3. Propose 2-3 approaches with trade-offs
4. Optional: HTML mockup -> agent-browser -> annotated screenshot
5. Present design -> get approval
6. Write spec doc if needed

Challenge Mode

1. Question every assumption -- "Why this? What breaks if X changes?"
2. Present alternatives
3. Push back on weak reasoning
4. Find edge cases -- "Empty list? 10,000 items?"
5. Consensus only when all concerns addressed

When to Use

Situation	Mode
New feature / architecture choice	Design
Review proposed approach / risky refactor	Challenge
"Should we use X or Y?"	Design -> Challenge winner
