brainstorming

brainstorming is a skill for Claude Code from guanyang/open-agent-hub. It costs 46 tokens per session (2,300 once invoked), scanned A, a copy of brainstorming, MIT.

A planning guide for turning a software idea or change into a clear design before coding. It helps decide how much discussion and documentation the work needs.

In plain words
What is it for?
Clarifying requirements, exploring implementation options, designing features, and preparing specifications for software work.
Why use it?
It reduces the risk of coding the wrong thing or overlooking important requirements. It also provides a way to handle both small changes and larger, less-defined projects.

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

brainstorming 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 5d ago.

The scan reads SKILL.md. This mod also ships 27 executable files (scripts/helper.js, scripts/index.js, scripts/node_modules/accepts/index.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.
