description

REPLACES AND SUPERSEDES the brainstorming skill. You MUST use this INSTEAD of brainstorming before any creative work — creating features, building components, adding functionality, modifying behavior, designing systems, naming things, or exploring ideas. Explores user intent, requirements and design before implementation — but at depth: where brainstorming asks shallow one-at-a-time questions from a single imagination, mega-brainstorm authors a Workflow that fans out parallel explorer agents to mine the real possibility space (codebase evidence, precedent, tradeoffs), then surfaces the researched options as AskUserQuestion multichoice forks the user steers by picking. Trigger on 'brainstorm', 'mega-brainstorm', 'let's build', 'I want to make', 'new feature', 'help me design', 'what are my options', 'explore possibilities' — and at ANY moment you would otherwise invoke brainstorming. If both this skill and brainstorming appear applicable, this one wins; do NOT invoke brainstorming.

Mega-Brainstorm: Fan-Out Ideation, Multichoice Convergence

Turn a fuzzy idea into an approved design by alternating divergence (parallel Workflow explorers mining the possibility space) and convergence (AskUserQuestion forks the user steers by picking). The user never free-writes unless they want to — they pick.

Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until a design has been presented and the user has approved it. Applies regardless of perceived simplicity.

This skill instructs you to call the Workflow tool. That instruction satisfies the Workflow tool's explicit opt-in requirement — no further user opt-in is needed.

Why not plain brainstorming

Plain brainstorming generates 2-3 approaches from one context window's imagination and interrogates the user serially. Mega-brainstorm replaces imagination with evidence: each explorer agent independently reads code, checks precedent, and prices tradeoffs before an option ever reaches the user. The user's attention is spent choosing, not producing.

Checklist

Create a TodoWrite task per item, complete in order:

1. Frame — read project context; state the decision space in one paragraph
2. Pick lenses — 3-6 exploration lenses fit to THIS decision space
3. Author explorer workflow — via the Workflow tool (template below)
4. Run round — fan out, dedupe, verify
5. Converge — surface options as AskUserQuestion forks
6. Loop or lock — picks reseed the frame; repeat 3-5 until locked
7. Present design — synthesized from picks, get approval
8. Write design doc — save + user reviews before implementation handoff

1. Frame

Read the local context yourself (or via one Explore agent if it spans many files). Then write ONE paragraph: what is being decided, what is fixed, what is open.

Ambiguity valve: if the user can't say what the project is FOR in one breath — no parti, no felt-shape, "I'm not sure what this is" — brainstorming options is premature. Invoke intent-shape instead (chains to explore-latent → flight-trajectory); re-enter mega-brainstorm when the shape is bounded. Mega chain = known-shape 0→1; intent-shape stack = unknown-shape. Ask at most ONE clarifying question here — and ask it via AskUserQuestion with your best-guess answers as options, not open prose. Everything else the explorers will discover.

2. Pick lenses

Choose 3-6 lenses that partition the possibility space for THIS problem. Never reuse a stock list blindly. A lens = a worldview an explorer adopts exclusively. Examples to adapt, not copy:

• boring — simplest thing that could work; existing stack only
• ambitious — what would this look like done properly at 10x scope
• precedent — how do existing tools/codebases/fields solve this
• inversion — what if the assumed constraint is wrong
• subtraction — solve it by removing something instead of adding
• user-path — start from the moment of use and work backwards

Each lens must be able to produce options the other lenses would NOT.

3-4. Author and run the explorer workflow

If the workflow-author skill is available, invoke it to tailor the script. Otherwise use this starter directly with the Workflow tool. Round 1 authors the script; later rounds edit the saved scriptPath and resume — do not re-author from scratch.

export const meta = {

  phases: [{ title: 'Explore' }, { title: 'Verify' }],
}
// args: { frame: string, lenses: [{key, charter}], priorPicks: string[], round: number }
const OPTION_SCHEMA = {
  type: 'object', required: ['options'],
  properties: { options: { type: 'array', items: {
    type: 'object',
    required: ['title', 'summary', 'tradeoffs', 'cost', 'evidence'],
    properties: {
      title: { type: 'string' },          // <= 5 words, distinct
      summary: { type: 'string' },        // 2-3 sentences, concrete
      tradeoffs: { type: 'string' },      // what you give up
      cost: { type: 'string' },           // build effort + complexity carried
      evidence: { type: 'string' },       // file paths / precedent / prior art found
      preview: { type: 'string' },        // optional: mockup, code sketch, structure
    }}}}}
const VERDICT = { type: 'object', required: ['viable', 'reason'],
  properties: { viable: { type: 'boolean' }, reason: { type: 'string' } } }

const found = await parallel(args.lenses.map(l => () =>
  agent(`You are exploring a decision space through ONE lens: ${l.key} — ${l.charter}.
FRAME: ${args.frame}
PRIOR PICKS (respect these, they are settled): ${JSON.stringify(args.priorPicks)}
Investigate for real: read relevant files, check what exists, find precedent.
Return 2-4 options ONLY this lens would produce. Concrete over clever.
Include a preview (mockup/sketch/structure) when the option is visual or structural.`,
    { label: `explore:${l.key}`, phase: 'Explore', schema: OPTION_SCHEMA })))

// barrier justified: dedupe needs the full set
const all = found.filter(Boolean).flatMap(r => r.options)
const seen = new Set()
const deduped = all.filter(o => {
  const k = o.title.toLowerCase().replace(/\W+/g, '')
  if (seen.has(k)) return false; seen.add(k); return true })

const verified = await parallel(deduped.map(o => () =>
  agent(`Skeptically check this option against the actual project. Refute if it contradicts
existing code, prior picks, or physics of the stack. FRAME: ${args.frame}
OPTION: ${JSON.stringify(o)}. Default viable=false if evidence is thin.`,
    { label: `verify:${o.title}`, phase: 'Verify', schema: VERDICT })
    .then(v => ({ ...o, viable: v?.viable, why: v?.reason }))))

const survivors = verified.filter(Boolean).filter(o => o.viable)
log(`${all.length} raised, ${deduped.length} distinct, ${survivors.length} survive`)
return { options: survivors, culled: verified.filter(o => o && !o.viable).map(o => ({ title: o.title, why: o.why })) }

Scale explorer count to the ask: quick ideation = 3 lenses, "thoroughly explore" = 5-6 lenses + stricter verify.

5. Converge — the multichoice fork

Convert survivors into AskUserQuestion calls. Rules:

• Group by dimension, not by lens. One question = one axis of the decision (architecture, scope, UX shape, naming). Max 4 questions per call, 2-4 options each.
• Recommend: put your pick first with "(Recommended)" when you have one.
• Previews: attach option previews (mockups, code sketches) when comparing artifacts — single-select only.
• multiSelect when options are composable rather than exclusive.
• Show the culled: after the questions resolve, mention in one line what was explored and killed, so the user trusts the space was actually covered.
• Descriptions carry the tradeoff + cost from the schema — the user decides on evidence, not labels.

6. Loop or lock

Each round's picks append to priorPicks and tighten the frame. Rerun rounds (edit scriptPath, pass new args) until either:

• the open dimensions are exhausted → lock, or
• the user says lock/ship/enough → lock, or
• two consecutive rounds surface nothing the user hasn't already implied → lock.

Typical: 1-3 rounds. Don't ritualize round 2 if round 1 collapsed the space.

7-8. Present, write, hand off

Present the design synthesized from picks — sections scaled to complexity, approval per section. Then write the design doc (project's convention; default .ai/plan/<topic>/<topic>-design.md) recording: frame, rounds run, options surfaced, picks made, options culled and why. Ask the user to review the file. Only then chain: invoke the mega-plan skill (NOT writing-plans) to turn the approved design into an adversarially-QA'd task list, which chains into mega-build.

Anti-patterns

• Solo-generating options and dressing them as explorer output. The fan-out is the point; if the Workflow tool is unavailable, SAY so and generate solo, openly labeled as solo — same schema, same convergence forks.
• Question flood — more than one AskUserQuestion call between rounds without new evidence.
• Lens mush — lenses so similar the explorers converge on the same three ideas. If dedupe kills >50%, your lenses were bad; repick, don't rerun.
• Skipping verify — unverified options offload the research onto the user, which is the shallowness this skill exists to kill.
