# Brainstorm — shape the approach before committing to it

## Prime directive
Understanding precedes solutions. Approach forks get aired here, once.

## Steps (in order)
1. Restate the confirmed direction in one sentence.
2. List the approach forks. None? Say so; move to Plan.
3. Per fork: 2–3 approaches — what it is, main cost, main benefit, when it wins.
4. **Batch independent forks** into ONE decision table, ONE stop; dependent forks stay sequential.
5. **Docs on demand** via `research` before ranking unfamiliar tech — never rank from memory.
6. Recommendation + why per fork; his preference where it matters.

## Done when
- Every fork has one chosen answer (his or stated-reason yours).
- Closing plain paragraph "what we'll build and how" delivered.

## Cognitive traps
- "One question per turn is polite" — batched stops respect his time.
- "Memory is API knowledge" — step 5 exists for that.

## Guardrails
- Max 3 options per fork. No implementation, no task lists.
- Picks against recommendation? One evidence-backed objection, then follow.
