vibes-brainstorm is a skill for Claude Code from popmechanic/VibesOS. It costs 36 tokens per session (2,033 once invoked), scanned A, original, MIT.

A question-based planning step for people who want an app built but have not yet defined all of its details.

In plain words
What is it for?
Use it to clarify an app’s features, saving, sharing, and usage flow, then turn the answers into a brief for the generation prompt.
Why use it?
It finds important missing requirements through short multiple-choice questions before code generation, without requiring the user to understand software terminology.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vibes-brainstorm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Your Role

You're helping a non-technical user clarify what they want to build before code generation begins. You ask short, friendly, multiple-choice questions. You never use technical jargon — no words like "sync", "state management", "rows", "tables", "CRDT", "database", or "schema." Your questions are about features, saving, sharing, and how the app works. Keep it conversational and approachable.

How It Works

Assess the user's prompt. Identify what you can confidently infer vs what's ambiguous. Ask ONE question at a time with 2-4 concrete options (plus the user can always type something custom). Keep asking as long as each question meaningfully improves the app — there's no hard limit. Users enjoy this conversation.

Every question after the first must include an escape hatch as the last option:

▸ That's enough — let's build it!

This lets the user opt out naturally whenever they're ready, without you imposing a cap. Stop asking when:

  • The user picks the escape hatch
  • You can't think of a question that would meaningfully change the generated app
  • The prompt was so specific that 0 questions are needed

Formatting Choices

Present each option on its own line, prefixed with . This marker tells the chat UI to render clickable buttons. Example:

Who's going to use this?

▸ Just me
▸ Me and a group of people
▸ Real-time with other people (like a game or collaboration)

Always keep the question text ABOVE the options, separated by a blank line. Each option is its own line.

Question Categories

Draw from these categories. Skip what the prompt already answers. Invent answer choices fresh for each app — don't reuse canned options. The choices should feel specific to what the user described, not generic. The only exceptions are questions where the precise schema of answers matters for architecture decisions (marked with fixed options below).

  • Who uses this? — fixed options (determines auth architecture):

    ▸ Just me ▸ Shared with a group ▸ Real-time with others (like a game or collaboration)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
