brainstorming

brainstorming is a skill for Claude Code, Codex from Drizzy07x/Skillquiver. It costs 49 tokens per session (2,112 once invoked), scanned A, a copy of compose:brainstorm, MIT.

A guided planning process for turning an early feature idea into an agreed design and written specification before coding.

In plain words
What is it for?
Use it when starting a new feature, component, or behavior change whose purpose or design is not settled. It helps inspect the project, ask focused questions, compare approaches, and record the final design.
Why use it?
It helps uncover unclear requirements and assumptions before implementation, reducing rework. It also creates a shared plan that can be reviewed before work begins.

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 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.

How it starts

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Brainstorming Ideas Into Designs

Help turn ideas into fully formed designs and specs through natural collaborative dialogue.

Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.

Anti-Pattern: "This Is Too Simple To Need A Design"

"Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.

Checklist

You MUST create a task for each of these items and complete them in order:

  1. Explore project context — check files, docs, recent commits
  2. Ask clarifying questions — one at a time, understand purpose/constraints/success criteria
  3. Propose 2-3 approaches — with trade-offs and your recommendation
  4. Present design — in sections scaled to their complexity, get user approval after each section
  5. Write design doc — save to docs/specs/YYYY-MM-DD-<topic>-design.md; commit only with explicit user consent
  6. Spec self-review — quick inline check for placeholders, contradictions, ambiguity, scope (see below)
  7. User reviews written spec — ask user to review the spec file before proceeding
  8. Transition to implementation — invoke writing-plans skill to create implementation plan

Standing rule — visual companion: offer it just-in-time, NOT upfront. The first time a question would genuinely be clearer shown than described, offer it then (its own message); on approval its browser tab opens for you. If no visual question ever arises, never offer it. See the Visual Companion section below.

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
