Brainstorming

Q: How do I know the Brainstorming output is good?

The skill verifies itself against its own quality checks: ≥20 ideas spanning ≥5 distinct strategies — not variants of two ideas; The weird tail exists (ideas that risk sounding silly); Zero evaluative language in the divergent set; Criteria were stated before scoring, and trace to the requester's situation.

🔵 Stable🕐 updated 2026-10-06 ✅ 5/5 🔷 SkillSpec L3 pm-method

Run a real brainstorm — divergent generation without judgment, then convergent selection with explicit criteria — instead of listing ten obvious ideas and calling it creativity. Use when asked to brainstorm, generate ideas or options, explore a solution space, or name something. Produces a genuinely wide option set (including the weird tail), then a shortlist selected against named criteria with the rejects preserved.

What to give it

▸The problem or prompt — , and what an idea must accomplish to count

▸Constraints that are real — (budget/tech/brand) vs assumed — challenge one assumed constraint deliberately

▸What's been tried or rejected already — avoids retreading; also reveals the requester's hidden criteria

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓≥20 ideas spanning ≥5 distinct strategies — not variants of two ideas

✓The weird tail exists (ideas that risk sounding silly)

✓Zero evaluative language in the divergent set

✓Criteria were stated before scoring, and trace to the requester's situation

✓Rejects preserved with revival conditions

⚠️ What it refuses to do

Do not judge while generating — one "(unrealistic)" mid-list collapses the whole divergent phase

Do not produce ten polished-obvious ideas and stop — that's a search result, not a brainstorm

Do not let the criteria appear after the list has been read — that's rationalising a favourite

Do not delete the rejects — the ledger is half the artifact

Do not ship the shortlist without the wildcard — a fully-safe shortlist means the exercise removed everything it was for
