brainstorming

brainstorming is a skill for Claude Code, Codex from MadAppGang/claude-code. It costs 24 tokens per session (4,490 once invoked), scanned B, original, MIT.

A collaborative planning skill for exploring ideas with multiple AI models, scoring possible approaches, and checking confidence in the result.

In plain words
What is it for?
Use it to plan systems such as authentication, rate limiting, dashboards, or real-time data synchronization.
Why use it?
It helps teams compare alternatives and validate a design before implementation, especially for larger or uncertain features.

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 B, and why

brainstorming scanned grade B with 1 finding 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 2d 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.

Brainstorming v2.0: Resilient Multi-Model Planning

Turn ideas into validated designs through collaborative AI dialogue with resilient model execution and confidence-based validation.

Overview

This skill improves upon v1.0 by addressing critical reliability gaps:

Key v2.0 Improvements:

  • No AskUserQuestion dependency: Uses Task + Tasks for structured interaction
  • Fallback chains: 3+ models per role ensures completion even if some fail
  • Explicit parallelism: Documented Task call patterns for parallel execution
  • Defined algorithms: Consensus matrix and confidence scoring are mathematically specified

When to Use

Use this skill BEFORE implementing any feature:

  • "Design a user authentication system"
  • "Brainstorm approaches for API rate limiting"
  • "Plan architecture for a new dashboard feature"
  • "Evaluate options for real-time data synchronization"

Prerequisites

Required Setup

/plugin marketplace add MadAppGang/claude-code
skill install superpowers:using-git-worktrees
skill install superpowers:writing-plans

# 2. Verify OpenRouter access (for multi-model)
export OPENROUTER_API_KEY=your-key

# 3. Configure models in ~/.claude/settings.json

Workflow

Phase 0: Problem Analysis (200-300 words)

Objective: Capture problem scope, constraints, and success criteria

How to Ask Users (Without AskUserQuestion):

// Pattern: Use Tasks to track questions, Read/Write for presentation

// 1. Write question to temp file
await Write({
  file_path: "/tmp/brainstorm-q1.md",
  content: `## Question 1 of 3

**What are the main constraints or requirements for this feature?**

Please respond with:
- Functional requirements (what it must do)
- Non-functional requirements (performance, scale)
- Any existing dependencies or integrations
`
});

// 2. Present file and wait for user response
// User reads file, provides input via conversation

// 3. Summarize understanding
const problemSummary = await Write({
  file_path: "/tmp/brainstorm-problem.md",
  content: `## Problem Understanding

**Constraints identified:**
- [From user response]

**Success criteria:**
- [Measurable outcomes]

**Scope boundaries:**
- [What's in/out]

---

**Does this accurately capture the problem?** (Reply "yes" to proceed or clarify)
`

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.

brainstorming is a skill published in the GitHub repository MadAppGang/claude-code (279 stars, last pushed 5mo ago), licensed MIT. It adds 24 tokens to every session and 4,490 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
