Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00035 | $0.01067 |
| Opus 5 | $0.00017 | $0.00534 |
| Sonnet 5 | $0.00007 | $0.00213 |
| Haiku 4.5 | $0.00003 | $0.00107 |
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 4d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brainstorming Skill
A structured design process that prioritizes exploration and validation before implementation. Sourced from obra/superpowers.
Core Principle
Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it.
Brainstorming is complete only when the user explicitly approves the final design specification.
Process Flow
Follow these nine steps in order. Do not skip steps.
Step 1: Explore Project Context
- Review existing files, documentation, and recent commits
- Understand the codebase structure and conventions
- Identify relevant prior work and dependencies
- Note technical constraints and existing patterns
Step 2: Offer Visual Companion (If Needed)
- As a standalone message, offer to create mockups or diagrams
- Use visual content only when it adds clarity beyond text
- Keep this offer separate from clarifying questions
Step 3: Ask Clarifying Questions
- Ask one question at a time — never batch multiple questions
- Prefer multiple-choice framing when possible
- Focus on understanding:
- Purpose and goals
- Constraints and limitations
- Success criteria
- User expectations
- Continue until you have sufficient context to propose approaches
Step 4: Propose 2-3 Approaches
For each approach, present:
- Description — what the approach entails
- Trade-offs — pros and cons
- Complexity — relative effort and risk
- Recommendation — which approach you favor and why
Let the user choose or refine before proceeding.
Step 5: Present Design
Scale documentation to complexity:
- Simple projects — a few sentences covering the approach
- Medium projects — 100-200 words with key decisions
- Complex projects — 200-300 words covering architecture, interfaces, and data flow
Present design in sections and request approval after each section before continuing.
Step 6: Write Design Documentation
Save the approved design to a spec document. Include:
- Problem statement
- Chosen approach with rationale
- System design with component breakdown
- Key interfaces and data flow
- Assumptions and open questions
- Implementation sequence
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 ByeongminLee/nextjs-claude-code (3 stars, last pushed 5mo ago), licensed MIT. It adds 35 tokens to every session and 1,067 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
stitch-ideate
Conversational design ideation agent that researches trends, explores visual directions, and refines ideas through adaptive questioning — then produces a rich PRD document and auto-generates Stitch screens. Your design buddy that thinks deeply before designing.
stitch-design-system
Extracts a Stitch design and generates production code artifacts — CSS custom properties with dark mode tokens, a Tailwind v4 @theme block, and a semantic design system document. Run this before framework conversion skills.
stitch-orchestrator
Master entry point for all Stitch design workflows. Routes from user request → design spec → prompt assembly → screen generation → iteration (edit, variants, design systems) → design system extraction → framework conversion (Next.js, Svelte, HTML, React Native, or SwiftUI) → optional quality pass.
stitch-a11y
Audits Stitch-generated components for WCAG 2.1 AA accessibility issues and applies fixes — semantic HTML, ARIA attributes, keyboard navigation, focus management, and screen reader support.
stitch-animate
Adds a purposeful animation layer to Stitch-generated components — CSS transitions, Framer Motion (React/Next.js), or Svelte transitions. Always respects prefers-reduced-motion.
stitch-design-md
Analyzes a Stitch project's screens and synthesizes a natural-language DESIGN.md — visual atmosphere, color palette with hex values, typography rules, and Stitch-ready prompt snippets. Use this before stitch-loop or any multi-page build to establish design consistency.
