brainstorming

brainstorming is a skill for Claude Code from ddtcorex/maestro-skills. It costs 46 tokens per session (3,114 once invoked), scanned A, a copy of brainstorming, MIT.

A planning guide for turning a coding idea into an agreed design or specification before implementation. It chooses a process based on whether the request is a feasibility check, a small change, or a larger piece of work.

In plain words
What is it for?
Use it to explore an idea, check whether something is possible, define a scoped code change, or prepare a design for approval.
Why use it?
It reduces the risk of building the wrong thing by clarifying context, requirements, and the proposed approach first.

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 yesterday.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/helper.js, scripts/server.cjs, scripts/start-server.sh, …), 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.

The opening of the file, as written. The whole thing — 295 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.

Before you start implementing, you must, in order:

  1. Lay out the approaches in a message of their own, and have your human partner pick one (see Lay out the approaches).
  2. Write the design doc, short or full (see Size the Work).
  3. Get their approval of that doc.
  4. Invoke the superpowers:writing-plans skill.

Two things aren't implementing: a spike they said yes to (see Spike to feel things out), and doing what they asked once they've opted out of the questions.

Look Before You Ask

In an existing project, or when they've given you context (a spec, a plan, a handoff, files they pointed at, earlier conversation), dig in before your first message. Read what they referred to and the code or material it connects to, and keep reading until you can explain how the relevant parts work today and what this change would touch. Never ask what the project or their context already answers.

Your First Message

Move the work forward, with one of these:

  • They've already said what they want (a spec, a plan, a detailed request): aim for about 200 words for the whole message. Echo their request back in your own words, so they can see whether you've got its shape: what they want, who it's for, and why, as far as they've said. Add what you found that bears on it: how the relevant parts work today and what the change would touch. If you found something they may not have considered that would change what they're asking for or how it has to be built, like a constraint, a conflict, or a cheaper path, say so plainly. How to build it comes later, once you understand what they want (see Lay out the approaches). End with one line inviting corrections, then one question about what they want: the thing their request leaves open whose answer would most change what gets built. Specs are often incomplete, so confirm before you build on one.
  • They haven't: one open question, in their own terms, about the biggest thing their request leaves unsettled. Say why you're asking: what the answer would change about what you build. For "a website for my bakery": "If it's mostly for people deciding whether to stop by, I'd lead with hours and what's in the case today; taking orders is a different site. What do you want someone to do when they land on it?"

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.
