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 5.1 | $0.00040 | $0.00432 |
| Opus 5.5 | $0.00016 | $0.00173 |
| Sonnet 5.5 | $0.00008 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
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 1mo 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.
What it actually says
Brainstorming — Design Exploration
Turn ideas into fully formed designs through collaborative dialogue.
When triggered, present a design before implementation. The design scales to complexity: short (few sentences) for simple tasks, detailed (pages) for architectural changes. Always get approval before proceeding to code.
When to Activate
- User explicitly asks: "design this", "how should i build", "what's the approach", "plan this out"
- User describes a feature/component/refactor and asks for guidance before coding
- User wants to explore trade-offs or multiple approaches to a problem
Process
- Explore context — check relevant code files, docs, recent commits
- Ask clarifying questions — one at a time, prefer multiple choice, understand: purpose, constraints, success criteria, scope
- Propose 2-3 approaches — name each, describe trade-offs, state your recommendation
- Present design — scale to complexity (1-2 sentences for trivial, multiple sections for architecture), ask approval after each section
- Get approval — wait for user buy-in before writing code
Design Principles
- One question at a time — don't overwhelm
- YAGNI ruthlessly — remove unnecessary features
- Design for isolation — break into units with one purpose, well-defined interfaces, independently testable
- Explore alternatives — always 2-3 approaches, with trade-offs
- Scope check — if request spans multiple subsystems, decompose first
In Existing Codebases
- Explore current structure and patterns before proposing changes
- Include targeted fixes only if they block the current goal
- Don't propose unrelated refactoring
Output
Present design as prose (short or detailed based on complexity), then ask: "Does this look right?" Wait for approval before proceeding to implementation.
What ships with it
2 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.
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 Benkapner/claude-code-basecamp (18 stars, last pushed 27d ago), licensed MIT. It adds 40 tokens to every session and 432 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.

make-landing
A design workflow for creating several visual versions of a landing page, hero area, cover, or slide surface. Each version is previewed, shown to a person for selection, and the chosen direction is then applied to the main project.
art-director
Orchestrate iterative visual style searches with branch prompts, decision graphs, feedback loops, and final direction selection.
html-draft
Use when user wants a standalone HTML diagram in flat engineering blueprint style — architecture diagrams, system flows, technical spec sheets, component maps. Generates one HTML file using Tailwind v4 (browser CDN) for layout and D3 v7 (CDN) for SVG diagrams. User-invoked only — do NOT auto-trigger. Triggers on…
make-3d
A 3D design workflow that creates several versions of a model in separate copies of a scene. The versions are shown using the same example data so a person can choose one before it replaces the main model.
frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications.
frontend-design
Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.
