A guided questioning process that turns a vague software idea or problem into a written specification before implementation begins.

In plain words
What is it for?
Use it to explore features, products, migrations, or other ideas that lack clear requirements.
Why use it?
It clarifies goals, limits, constraints, success measures, and risks before code or architecture decisions are made.

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 9d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brainstorming

Structured pre-implementation design exploration. Transforms a vague idea into a written spec through focused, one-at-a-time questioning before any code is written, any plan is created, or any architecture is decided. The spec is the deliverable - everything else follows from it.

No code until the spec is written and approved.

When to Use

  • The user says "I want to build X" but has no written requirements
  • A feature request exists as a sentence or two with no detail
  • The user asks "how should I build X" before defining what X actually is
  • Someone says "let's brainstorm" or "help me figure this out"
  • A problem statement exists but the solution space is unexplored

Quick Start

/brainstorming user authentication for a SaaS app
/brainstorming migrate our monolith to services
/brainstorming                                     # asks what to explore

If $ARGUMENTS is provided, use it as the initial topic and skip straight to Phase 1. If no argument, ask: "What idea, feature, or problem would you like to explore?"


Workflow

This skill uses guided phases - each phase is a separate file loaded one at a time. Every phase ends with a gate where you must wait for user confirmation before proceeding. Do not skip phases or merge them.

Phase File What it covers
1 Intake Read context, classify maturity, summarize understanding
2 Divergence Expand problem space with one-at-a-time questions across 7 categories
3 Convergence Narrow to concrete scope, lock must-haves and non-goals
4 Spec Writing Write full spec from gathered material, run quality checklist
5 Approval Get explicit user approval, hard-gate implementation

Start by loading Phase 1. After the user confirms each phase, load the next. Never load multiple phases at once. Never skip a phase.

Changes

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.
