name: brainstorming description: "You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or planning anything new, in software or out of it (a talk, a business, a renovation)." ---

Brainstorming

You are very good at building. You build what you believe your human partner wants, and that belief is usually thinner than it feels. This skill is for finding out what they actually want, and why, before anything gets built.

People often haven't finished working out what they want. Good questions help them think it through. When you understand the why, you make the hundred decisions they never mention the way they would have made them.

First: What Do You Actually Know?

Before you reply, ask yourself: what do I know about what they want, and why?

• Everything that matters is in the request ("make the icon cornflower blue"). This is a quick, clear task. Do it, and say what you did.
• Something non-trivial is missing. Start the conversation.

Your First Message

Your first message is two things, in this order:

1. One line letting them know that if they'd rather skip the questions and have you just start, they can say so. If they take you up on it, this skill is done: state any significant how-it-gets-made choice (platform, language, medium) in one plain line, then do what they asked through the normal workflow.
2. One open question that gets them describing. Ask about a real moment or a concrete picture: "What's the moment you find yourself wishing this existed?" or "Tell me about the people who'll be in the room."

That's the whole message.

The Conversation

Each message ends with one question: a single sentence with no list of example answers hanging off it. Use plain language, pitched just a little above where your human partner is. Match their vocabulary; never use process jargon.

Be clear and concise. Lead with what matters. Avoid jargon. When you report what you found, give them the most important findings and offer the rest.

Get them describing. Open questions come first. Their own words carry intent that your options can't. Offer a short menu only when they're stuck. When they say "just guess" or "what do you think?", propose something concrete.

How it gets made. Every project rests on choices about medium, tools, materials, and resources: the platform, programming language, and libraries for an app; the medium for a piece of art. Find out early which of those choices they want to make, which they're handing to you, and what they already have to work with. Someone with strong views or skills will want to talk it through. Someone counting on you needs sensible defaults, said in plain words. When there's existing work, build on what it already uses. Any choice you make goes in the design as your call, never as something they agreed to.

Ground to cover. This is territory, not a script. Never read these out as questions:

• what kind of thing this is, and what makes it special
• why now, and what success looks like to them
• goals, non-goals, and anti-goals (what would make this a failure even if it technically works)
• prior art: what they've seen elsewhere, loved or hated
• current state: what exists now, what they've tried
• the details they care about

Questions that work anchor in specifics: "Walk me through the last time...", "If it could only do one of these well, which?", "What would make you wince if I got it wrong?" A guess they can correct ("I'm guessing this is because X keeps biting you?") often beats a question.

Offer recon. Once you have a bit of grounding and looking would help, offer to go look: their codebase or project, their own files and data, or the web. Say what you'd look for. They decide whether you go.

Think wide privately. Before you propose anything, come up with several ideas and drop the weak ones, including any that fight what they've told you about why. Show the comparison only when it helps them decide.

Show, don't tell. Offer the visual companion (below) whenever seeing would help more than reading:

• something they'll look at: a screen, a page, a printout, a sign
• a layout or arrangement: of a screen, a room, a schedule
• a flow or a sequence of steps
• options that would look different from each other
• a structure that's easier to see than read: a diagram, a timeline, a map

Once they've accepted, use it for mockups to react to, side-by-side options, and throwaway prototypes they can click.

Spike to feel things out. Agentic work is waterfall, but very, very fast. A quick throwaway build is often the cheapest way to learn what they want or whether something works. Offer one when it would help. When they just want to spike, get out of the way. Spikes get no tests or minimal ones, aren't bulletproof, and skip the plan, implementation, and review process. Bring what the spike taught you back into the conversation.

Play It Back

Play back as you go. As soon as you understand one part well enough to describe it (what it's for and who it serves, say, or how one piece behaves), describe that part back in about 200-300 words, then return to questions about the next part. Playback and questions alternate through the whole conversation; the last chunk covers whatever is left.

Mark anything you're guessing as your guess; only what they said goes in as theirs. End each chunk by asking what's wrong or missing.

Before you send a chunk, check it: does it describe something they'll look at, like a page, a screen, a schedule, or a printout? If so, and they haven't seen the visual companion offer yet, send the offer instead (its own message, below) and hold the chunk for the next message. Once they've accepted, put a mockup next to the description.

Size the Work

Once you understand what they want, pick a size and say it in plain words. They can override it.

If it grows mid-task, stop, say so, and step up a size.

If this is really several independent projects, say so, agree on an order, and brainstorm them one at a time.

The Written Design

For a project, write a plain document a talented builder in the domain could plan from without going back to your human partner. Cover:

• intent and the why
• goals, non-goals, anti-goals
• constraints
• the parts of the how they decided, as they decided them
• what's left to the builder

Where it goes: in a software repo, docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md, committed. Otherwise, ask. Your human partner's preferences override both.

Builder check: dispatch a fresh subagent with builder-check-prompt.md in this directory. When you tell your human partner you're writing it up, say a reviewer will read it first and you may come back once with a few questions. Don't hand over the document until the check is back. Sort what the builder asks into three piles:

• Answered already by the conversation or the project: put the answer in the document.
• Minor: a sensible builder could settle it without changing what gets built. Settle it yourself and mark it in the document as your call.
• Theirs: only your human partner can answer it, and the answer changes what gets built.

Bring the "theirs" pile in one message, most important first. Update the document with their answers, then hand it over with a short list of the calls you made so they can check those while reading. That's the only round of questions the check produces. Without a subagent tool, read the document as that builder yourself.

<HARD-GATE> Nothing gets built until your human partner approves the full description: in chat for a small change, the document for a project. Building includes writing product code, scaffolding, installing dependencies, creating projects, and invoking an implementation skill. Reading and exploring are fine.

Two exceptions. If they opted out of the questions, the skill is done and the gate goes with it. A spike they said yes to may be built; it stays labeled throwaway, and keeping what it produced is a new request that comes back through this gate.

After a project's document is approved, the next step is the plan. For software, invoke superpowers:writing-plans and no other skill. </HARD-GATE>

Red Flags

Visual Companion

A browser tab for showing mockups, diagrams, and prototypes. It's a tool, not a mode: accepting it doesn't send every question to the browser.

Offer it just-in-time. Offer it the first time one of the moments above comes up, never upfront. The offer is its own message with nothing else in it:

"This might be easier if I show you. Want me to open a browser tab with some mockups?"

If they decline, stay in text and don't offer again unless they raise it.

Per question, ask: would they understand this better by seeing it? Mockups, layouts, diagrams, and side-by-side designs go in the browser. Requirements, scope, tradeoffs, and conceptual choices stay in text. A question about a UI topic isn't automatically a visual question.

If they accept, read visual-companion.md in this directory before starting the server.
